Procurement Engineering Standard Purchase Clause

Transcription

1 1.0 QUALIFICATION BY TESTING AND ANALYSIS This EQPR is intended to be used when buying Valve Positioners, Regulators, Actuators and Spare Parts manufactured by Dresser Inc., formerly Dresser Flow Control-Masoneilan Operations (hereinafter Dresser) for use throughout Ontario Power Generation (OPG) sites in nuclear safety-related applications which require environmental qualification (EQ). Note: OPG EQ DRESSFLOB is the applicable EQPR clause for the Safety Relief Valves and Safety Valves manufactured by Dresser-Consolidated Operations. 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. Dresser 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: Valve Positioner(s) certified to - Dresser Report # TR-012, R01, Environmental Qualification of Dresser 2 Nuclear Control Valve (Item 105) for Wolsong 2, 3, 4. Actuators and spare parts as described in the Dresser certified drawings which have been accepted by OPG and are referenced in the P.O. item description. Pressure regulators and spare parts certified to: Dresser Test Report TR-045, R01, Environmental and Seismic Qualification Tests of Dresser Size 160 Actuator and Accessories for Qinshan NGS Unit 1 & 2 or Dresser Test Report TR-039, R00, Environmental and Seismic Qualification of Dresser Item 110, 3 Control Valve SCN543L0771, and Masoneilan North American Operations Dresser Valve & Controls Division Report No , R03, Generic Nuclear Safety-Related Qualification for Model 8005N Electropneumatic transducer and 77N-4 Airset per IEEE , IEEE , and IEEE This clause applies to OPG Purchase Orders placed on or after April, 2015 Page 1 of 7

2 2.0 CHANGES IN DESIGN AND SUBSTITUTION OF QUALIFIED MATERIALS Changes made to EQ items manufactured and supplied by Dresser that were originally tested or previously assessed and environmentally qualified by OPG are to be tracked. Dresser 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. Changes to non-metallic components are of particular interest to OPG. Dresser shall ensure contractual provisions and QA program requirements imposed on suppliers and subsuppliers is such that Dresser will be notified of any such changes that may occur within the supply chain. If any of these changes take place then Dresser shall notify the OPG 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, Dresser 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. The 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 OPG Design Authority may solicit Dresser s input to the decision, the decision of the OPG Design Authority will be final. Dresser 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 OPG 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 OPG Engineer accepts that changes in design, sub-suppliers, materials, and manufacturing methods may be necessary as technology and manufacturing processes change with time. The OPG Engineer also accepts that companies may not be able to track all changes that occur over a long period of time. It is The OPG 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 Dresser manufacture/supply to OPG, Dresser shall implement and maintain a quality assurance program that provides assurance that Dresser tracks material substitutions, design changes, sub- This clause applies to OPG Purchase Orders placed on or after April, 2015 Page 2 of 7

3 supplier 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, Dresser s QA program shall meet the requirements of minimum 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, Dresser shall assign to each product or service or batch a unique identification/unique identifier such as serial number, date code, batch code to distinguish apparently identical products. Dresser s QA Manual as audited/accepted by OPG to the requirements of CSA Z , along with the requirements specified in the purchase order is acceptable to OPG to meet this requirement. Non-conformances with a disposition to Repair or Use-as-is require the concurrence of all responsible parties, and submission to OPG for acceptance. 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 N and Update No. 2 standard. All the Dresser items and spare parts shall be traceable to Dresser audited location in Avon, Massachusetts. Dresser s distributor in Canada shall also implement a quality assurance program that: Provides assurance that there is no substitution of product specified in the purchase orders without prior approval. Such requests are to be submitted to the OPG Engineer for approval using N-FORM-10393, Provides rigorous controls to ensure that batch trace controls are not lost during the process of receiving, storing, packaging, and shipping the subject products. Conveys/transfers information to and from Dresser in an accurate and timely fashion. In order to provide the required assurance, Dresser Canadian distributor s quality assurance program shall meet the requirements of CSA Z (distribution activities). 4.0 INSPECTION AND TEST PLAN AND SPECIAL PROCESS PROCEDURE APPROVALS For initial procurement of new items not previously manufactured/supplied by Dresser for use in nuclear safety-related applications requiring being EQ at OPG, Dresser shall submit an Inspection and Test Plan (ITP) to OPG for review and acceptance following the award of the contract and prior to initiating the work described on the plan, unless directed otherwise in the OPG purchase order. ITP required under CSA CAN3 Z299.2/3-85 need not be resubmitted for review and acceptance if they have been previously accepted by OPG. Changes to the ITP shall to be submitted to OPG for acceptance. For repeat orders Dresser s Certificate of Conformance statement, that: the item supplied is equivalent to the item previously manufactured/supplied and environmentally qualified by OPG s Engineer, and meets the requirements outlined in Section 1.0 above, it is deemed to satisfy the requirements for further review and acceptance of ITPs, manufacturing, testing and special process procedures. The ITP Plan may be in any format to meet the Company s needs but as a minimum, should indicate: As a first step in developing the ITP Dresser shall verify that the primary controlled documents identify the materials of construction of the item(s). Where Dresser identify additional non-metallic components that are not specified in the primary controlled document, Dresser shall obtain further direction from the OPG Engineer to verify that these additional components do not affect the Engineer s EQ Assessment that the item is qualified for installation in EQ applications at OPG. This clause applies to OPG Purchase Orders placed on or after April, 2015 Page 3 of 7

4 The methods by which Dresser will verify the materials/compounds used and their equivalency to those used in the assessed (based on the tests or analysis) items, as specified in item description and/or primary controlled documents, The products or services to be subcontracted and the quality assurance program requirements imposed on the subcontractors, The methods by which Dresser verifies subcontractors performance (incoming inspection, verification and test, source surveillance, etc), The identification of each inspection and test point located relative to the production cycle, The characteristics to be inspected and tested together with the sampling plan and acceptance criteria to be used (including those used for final inspection), Justification for using a sampling plan (i.e. How does Dresser show that the lot is homogeneous), Customer witness and or hold points (if applicable), If lots or batches will be used, Records to be maintained during and after inspections, 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. Dresser should make no significant change to the ITP, critical process procedures, or NDE procedures without notification to the OPG Engineer for those changes and using the procedure described in section 3.0 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 acceptance for changes shall delay completion of the work, Dresser is to notify the OPG via OPG Buyer at least two weeks in advance of the delay occurring in order that the OPG 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 and 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. Dresser shall provide evidence of that registration by way of a Canadian Registration Number (CRN) along with the shipment. 6.0 CSA ELECTRICAL SAFETY CERTIFICATION/APPROVAL This section is N/A 7.0 SEISMIC QUALIFICATION REQUIREMENTS Dresser 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.
