Procurement Engineering Standard Purchase Clause

Transcription

1 1.0 QUALIFICATION BY TESTING AND ANALYSIS This EQPR is intended to be used when buying valves and related parts from Valcor Engineering Corporation (hereinafter Valcor) for use throughout Ontario Power Generation (OPG) sites in nuclear safety-related applications which require environmental qualification (EQ). OPG Engineer (see the Contract Standard for definition of Engineer ) generally assesses and qualifies electrical equipment for use in applications which require Environmental Qualification (EQ) by conducting qualification tests (or referring to qualification tests performed by others) whereas mechanical items are generally qualified by analysis. Once it has been established that an item is environmental qualified, it is necessary to ensure that successive purchases of the item shall be equivalent to the qualified item. In order to do so, it is necessary to clearly establish the critical characteristics of the qualified item so that these can be need to be replicated and verified. These critical characteristics may be shown on one or more of a number of different documents including test reports, qualification reports, the manufacturer s catalogue, manufacturer s drawing(s), bill(s) of material, specification(s) etc. So as not to limit the generality of the foregoing list, the document that describes the critical characteristics that need to be replicated shall be referred to herein as the primary controlled document. For EQ materials it is essential that the primary controlled document clearly identifies the materials of construction as well as other critical characteristics of the item. EPRI NP-5652 and TR may be used as a guideline for a more detailed explanation of critical characteristics. The primary controlled document shall be selected by OPG Engineer and stipulated in purchase order item description. In every instance, the content of the primary controlled document shall be under rigorous revision control. In instances when the primary controlled document defines most but not all critical characteristics, and in instances when the primary controlled document provides configuration or material selection options, the required characteristic or material option(s) shall be stipulated in the purchase order item description. Valcor item shown in the purchase order item description has been assessed and environmentally qualified by the OPG Engineer for use in nuclear safety related applications based on the following primary controlled documents: Report No: QR , Rev. B, dated 09/18/2002 titled: Qualification Test Report for Solenoid Valve Models V , V , V , V , V , V , V , and V Report No: MR Rev. D, titled: Similarity Qualification Report for Solenoid Valves V /5/6 to Solenoid Valves V and V dated April 19, 1996 Report No: MR , Rev. A, titled: Similarity Qualification Report for Solenoid Valves V dated December 20, 1999 Report No. QR , titled Qualification Test Report for IEEE Class 1 E Solenoid Valve P/N V Valve Type I Report No. QR , titled Qualification Test Report on SNUPPS Solenoid Valve dated Feb 26,1999 Note: Test reports revision levels as indicated above or latest revision as accepted by OPG. 2.0 CHANGES IN DESIGN AND SUBSTITUTION OF QUALIFIED MATERIALS Changes made to environmentally qualified items manufactured and supplied by Valcor that were originally tested or previously assessed and environmentally qualified by OPG are to be tracked. Valcor shall advise OPG in the event that changes take place in the following areas: design of the product, material/compounds used, manufacturing methods, non-destructive testing procedure, and test reports. Some changes, which may appear insignificant and not deem to be reported to the client (since fit, form, and function are met), can invalidate the equipment nuclear performances. This clause applies to purchase orders placed on or after June 29, 2016 Page 1 of 6

2 Changes to non-metallic components are of particular interest to OPG. Valcor shall ensure contractual provisions and QA program requirements imposed on suppliers and subsuppliers is such that Valcor will be notified of any such changes that may occur within the supply chain. If any of these changes take place then Valcor shall notify the buyer using the Vendor Parts/ Material Substitution Control form N-Form during bidding or the Concession Application form N-Form subsequent to contract award. As an alternative to the preceding paragraph, Valcor shall notify the OPG Buyer, using the same forms, if for any reason it is unable to provide assurance that there have been no such changes since the item was originally evaluated/ tested for use in a nuclear safety application. OPG Buyer will forward all such notifications to the Design Authority in OPG. The responsible Design Authority shall make all decisions relating to the need to re-evaluate and/or re-test and the item. Although the Design Authority may solicit Valcor s input to the decision, the decision of the Design Authority will be final. Valcor is advised that: This item will be installed in a nuclear safety system. That system will be required to operate following a very unlikely but theoretically possible design basis accident. If such an accident occurred the item could be subjected to a harsh environment consisting of chemical and pressure transients, radiation, steam, and elevated temperature. It is possible that the design basis accident could occur at a time when the item has already been subjected to many years of normal operation when it is nearing the end of its useful operating life. This item has been rigorously evaluated /tested, and the Engineer (see the Contract Standard for definition of Engineer ) expects that it will perform its intended safety function following exposure to this harsh environment. The Environmental Qualification Assessment (EQA) has established that the item may not perform its intended safety function if there is a substitution of materials, changes in design, or changes in manufacturing methods. This is especially true for changes or substitutions of non-metallic components used in the construction of this item. Some non metallic components are known to be subject to degradation in a harsh environment and can deteriorate quickly when exposed to steam, heat, or especially when exposed to high levels of radiation. The Engineer accepts that changes in design, sub-suppliers, materials, and manufacturing methods may be necessary as technology and manufacturing processes change with time. The Engineer also accepts that companies may not be able to track all changes that occur over a long period of time. It is The Engineer s objective to minimize unnecessary changes that would necessitate a reevaluation of the item s ability to perform its intended safety function following a Design Basis Accident as even minor changes may dictate the need to retest or re-qualify the item. In any event, it will certainly dictate the need to evaluate the effect of the change, and a revision to the EQA to ensure that the new item will perform the same intended safety function as the item that was previously qualified. 3.0 QUALITY ASSURANCE PROGRAM REQUIREMENTS For the EQ items that Valcor manufacture/supply to OPG, Valcor shall implement and maintain a quality assurance program that provides assurance that Valcor tracks material substitutions, design changes, subsupplier changes, manufacturing and non-destructive testing process changes that may occur during the course of time and that the items meet the design requirements and are equivalent to those originally evaluated and environmentally qualified by OPG. In order to provide such assurance, Valcor s QA program shall meet the requirements of CSA Z QA standard, including the requirement for product traceability. Traceability is required by this contract, and therefore in accordance with CSA Z299.1/2/ QA standards, Valcor shall assign to each product, service or batch a unique identification/unique identifier such as serial number, date code, batch code to distinguish apparently identical products. Valcor s QA program as audited/accepted by OPG, along with the requirements specified in the purchase order is acceptable to OPG to meet this requirement. This clause applies to purchase orders placed on or after June 29, 2016 Page 2 of 6

3 Non-conformances with a disposition to Repair or Use-as-is require the concurrence of all responsible parties, and submission to OPG for acceptance. In addition: For ASME Section III materials, the quality program shall meet the requirements of ASME, Section III, subsection NCA 3800 or NCA 4000 (where the scope of the quality program includes acting as a material organization), to the code edition and addenda specified in the purchase order. For ASME, Section III components, the quality program shall meet the requirements of ASME, Section III, subsection NCA 4000, to the code edition and addenda specified in the purchase order. A valid certificate of authorization issued by by an authorized registrar (i.e. ASME, TSSA, other Canadian provincial jurisdiction etc) shall be required, in accordance with the CSA N285.0 standard. All the Valcor items and spare parts shall be traceable to Valcor audited location in Springfield, NJ. 4.0 INSPECTION AND TEST PLAN AND SPECIAL PROCESS PROCEDURE APPROVALS Inspection and Test Plans required under CSA CAN3 Z299.2/3-85 need not be resubmitted for approval if they have been previously accepted by OPG. Changes to these shall to be submitted to OPG for acceptance. For repeat orders Valcor s Certificate of Conformance statement, that the item supplied is equivalent to the item previously qualified by OPG s Engineer, and meets the requirements outlined in Section 1 above is deemed to satisfy the requirements for further review and approval of Inspection and Test Plans, manufacturing, testing and special process procedures. Valcor shall make no significant change to the I&TP, critical process procedures, or NDT procedures without notification to the OPG Engineer for those changes. This notification is to be received at least 4 weeks prior to the commencement of the work to be changed and shall be accompanied by a detailed description of the planned change (including detailed procedures where applicable). Note: Personnel performing inspection, witnessing or monitoring of item critical characteristics for their acceptance must not be those who have performed the work being inspected or report directly to immediate supervisors responsible for producing the work unless specifically permitted otherwise in the I&T Plan and agreed to in writing by the customer before the contract is let. Valcor shall make no significant change to the I&TP, critical process procedures, or NDE procedures without notification to the OPG Engineer for those changes and using the procedure described in section 3. This notification is to be received at least 4 weeks prior to the commencement of the work to be changed and shall be accompanied by a detailed description of the planned change (including detailed procedures where applicable). In the event that a delay in receiving the OPG Engineer s approval for changes shall delay completion of the work, Valcor is to notify the OPG via OPG Buyer at least two weeks in advance of the delay occurring in order that the buyer can expedite engineering approval and thus avoid the delay. 5.0 REGISTRATION WITH TECHNICAL STANDARDS AND SAFETY AUTHORITY Pressure retaining items are to be registered with the Pressure Vessel Division of the Technical Standards and Safety Authority (TSSA) of the Province of Ontario. This registration shall be in accordance with CAN/CSA- N & Update No. 2 and the ASME code and class specified on the OPG Design/technical specification referenced in the OPG purchase order (P.O.) item description. For nuclear class 1, 2 or 3 components and materials, Valcor shall maintain a quality assurance program that meets the requirements of NCA 4000 (for components) or NCA 3800 (for materials) and hold valid appropriate ASME certificate of authorization (N, NPT, QSC). This clause applies to purchase orders placed on or after June 29, 2016 Page 3 of 6

4 Code Reconciliation: Items shall be manufactured in accordance with the Technical Tender Document Specification in the P/O. Since the items have different applications in OPG s Nuclear Power Plants and require that components be manufactured to different code effective dates as early as 1974 (Summer Addendum), Valcor shall manufacture the item in accordance with P/O requirement including ASME code year, and addenda. If is not possible to manufacture the item to the required code year, Valcor shall provide a code reconciliation statement which identify any changes to the ASME code since the code effective date reflected on the drawing referenced in the item description shown in the purchase order. This statement shall indicate that the changes to the code have had no effect on the design of the component. If a change to the code has impacted the design or manufacture of the item, Valcor shall identify that change using the forms noted in Section 2, Changes in Design and Substitution of Qualified Materials. 6.0 CSA ELECTRICAL SAFETY CERTIFICATION/APPROVAL As per Ontario Electrical Safety Code, it is Valcor s responsibility to obtain and provide evidence that the item supplied is electrically safe. The item shall bear the CSA certification symbol or CSA/ESA approval sticker, which identifies that the item is certified for use in Canada. Spare parts are not approved as individual items; these are only approved once incorporated into the item and hence spare parts will not be labeled with CSA approval symbol. 7.0 SEISMIC QUALIFICATION REQUIREMENTS Valcor is to demonstrate the seismic qualification for the item(s) are in accordance with the OPG Design/Technical specification referenced in the OPG purchase order (PO) item description. For repeated orders Valcor Certificate of Conformance statement that the item supplied is equivalent to that originally supplied by Valcor (see Section Certification to Accompany Shipment ) is deemed to satisfy the Engineer s requirement for seismic qualification of the item. 8.0 MARKING AND TAGGING Whenever possible, a permanent, corrosion resistant metal tag shall be affixed to each item. Tags are to be permanently attached when appropriate with mechanical fasteners (e.g., screws, rivets, weld or stainless steel wire). Self-adhesive labels and glue are prohibited to ensure that the tag shall not come off during accident conditions. The tag shall be applied in such a manner so as not to affect the function of the item. If it is not possible to attach a tag, Valcor may permanently mark, etch or scribe data on the item, whichever is applicable and appropriate usually based on equipment size. This tag and/or appropriate marking on the item shall contain the following information as defined in the item specific design specification. Manufacturer s name and model number/part number Manufacturer s unique identifier such as serial number, batch/lot control number or cure date/ manufacturer date (to ensure traceability) Design pressure at design temperature (as applicable) Pressure Rating Voltage Rating Power rating in watts Valcor shall provide the following details either on the metal tag described above or on an additional tag attached to the item by a stainless steel wire in such a manner so as not to affect the function of the item: Canadian Registration Number (CRN) (as applicable) Nuclear class, code effective date, CSA Approval symbol or Electrical Safety Authority approval sticker This clause applies to purchase orders placed on or after June 29, 2016 Page 4 of 6

5 OPG Catalog ID number All marking and tagging shall be clear, unambiguous and indelible. Alternatively, spare parts not marked or tagged shall be shipped in suitable packaging and labeled as outlined in Section 9 below. 9.0 PROTECTION FROM DEGRADATION DURING SHIPMENT OR STORAGE All orifices shall be plugged and/or sealed as applicable, to prevent ingress of foreign materials, dust, dirt, etc. The items shall be individually packaged and protected from degradation during shipment in accordance with ASME NQA-1a-2009, Part II, Subpart 2.2 Level B. Individual packaging shall provide protection from ultraviolet (UV) radiation, where applicable. Where sealed packaging is used, the seal is to be such that the item can be removed for inspection and resealed in the same package for long term storage in Level B. It is OPG s intention to store EQ materials in level B storage. Packaging requirements for level B items are specified in NQA-1a-2009, Part II, Subpart 2.2, section 302.2, which refers to Level A packaging specification defined in section with the exclusion of requirement 302.1(a) (b) Items shall have been inspected for cleanness immediately before packaging. Dirt, oil residue, metal chips, or other forms of contamination shall have been removed by approved cleaning methods. Any entrapped water shall have been removed (c) Items not immediately packed shall be protected from contamination (d) Items requiring protection from water vapor, salt air, dust, dirt or other forms of contamination penetrating the package, shall be packaged with a barrier (e) Items that require protection from damage during shipping and handling shall be packaged in containers or crates (see para. 307 of NQA-1a-2009, Part II, Subpart 2.2) (f) Items that can be damaged by condensation trapped within the package shall be packaged with approved desiccant inside the sealed waterproof and vapor-proof barrier or by an equivalent method (g) All openings into items shall be capped, plugged or sealed. Weld end preparations shall be protected against corrosion and physical damage (h) Items packed in containers shall be blocked, anchored, braced or cushioned to prevent physical damage to the item or barrier (i) Items and their container shall be identified by marking.

Manufacturer s unique identifier such as serial number, batch/lot control number or cure date/ manufacturer date (to ensure traceability) Date of manufacture. Item shelf life (if applicable) OPG s Purchase order number. OPG s Catalogue Id. number. Notes: Valcor s Packaging and Shipping Procedure S903 (latest revision) is acceptable if it meets the requirements of ASME NQA-1a-2009, Part II, Subpart 2.2. Resealing of Valcor provided packaging requires use of heat seal equipment. In situations where Valcor cannot provide the spare parts packaging with UV protection, a second set of unused labels shall be provided with the marking as detailed above. This clause applies to purchase orders placed on or after June 29, 2016 Page 5 of 6

6 Valcor is to include a shelf life statement, when applicable, with every purchase order indicating the shelf life of each item (Catalog ID Number) on the purchase order. Shelf life for every item should be assigned by Valcor under their quality assurance program as reviewed and in accordance with industry (e.g., EPRI, Mil Spec, etc.) recommended shelf life values for similar components. Shelf life can be determined by using EPRI methodology: EPRI Report NP6408, Guidelines for Establishing, Maintaining and Extending the Shelf Life Capability of Limited Life Items (NCIG-13): Typical Data from EPRI Report: NP6408, App. B, List of Generic Shelf Lives (Partial List) Material Shelf life in years (EPRI NP6408 May 1992) EPDM/EPR 60 Neoprene 36 Nitrile 14 Nomex 60 PEEK (Polyetheretherketone) 20 Teflon 60 Viton 49 Tefzel 60 OPG Receiving Inspector should not accept the item for delivery if the remaining shelf life is less than 70% of the available shelf life at the time of delivery without prior written consent CERTIFICATION TO ACCOMPANY SHIPMENT Valcor shall supply a certificate, which shall accompany the shipment of the item or spare part. This certificate shall be signed by Valcor s QA authority and shall certify that: The item has been manufactured in accordance with Valcor QA program (compliant with the requirements of 10CFR50 App. B) as audited/accepted by OPG and any additional requirements of the OPG purchase order.
