1 1.0 QUALIFICATION BY ANALYSIS This EQPR is intended to be used when buying Hayward Gordon pumps and spares from Numet Engineering currently part of Rolls-Royce Civil Nuclear Canada Ltd (hereinafter Numet Engineering) for use throughout Ontario Power Generation (hereinafter OPG) nuclear sites in safety-related applications which require environmental qualification (EQ). Notes: The pumps are classified as ASME Section III Class 3. Hayward Gordon, the Original Equipment Manufacturer (OEM) is not qualified in OPG Approved Supplier List to manufacture and supply these nuclear class items. Rolls-Royce Civil Nuclear Canada Ltd has entered OEM partnership with Hayward Gordon Pumps to supply Hayward Gordon Pumps and associated spare parts. The CRNs provided for this product name will be under the name of the Rolls-Royce Civil Nuclear Canada Ltd. Therefore, Numet Engineering (part of Rolls-Royce Civil Nuclear Canada Ltd) is the Manufacturer of Record for these pumps. Once it has been established that an item is environmentally qualified (EQ), 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 replicated and verified. These critical characteristics may be shown on one or more of a number of different documents including manufacturer s drawing(s), test reports, bill(s) of materials, technical 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. See EPRI NP-5652 and TR 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 OPG purchase order (P.O.) item description. Numet Engineering is advised that the item shown in the P.O. item description has been assessed and qualified by the OPG Engineer for use in nuclear safety-related applications based on the primary controlled documents referenced in the OPG P.O. item description. All the items and spare parts are to be supplied in accordance with the requirements of the OPG Design/technical specifications referenced in the OPG P.O. item description. If there is no primary controlled documents referenced in the item description Numet Engineering is to contact the OPG Buyer for further direction. If there is a discrepancy between the primary controlled document, OPG specification data sheet and the required item description, Numet Engineering shall contact the OPG Buyer for resolution, using the forms referenced in section 2.0 below. 2.0 CHANGES IN DESIGN AND SUBSTITUTION OF QUALIFIED MATERIALS Changes made to the Numet Engineering items that were previously assessed, and qualified by OPG are to be tracked. Numet Engineering 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 for the commercial applications and not deem to be reported to the client (since fit, form, and function are met), can invalidate the equipment qualification. Changes to non-metallic components are of particular interest to OPG. This clause applies to purchase orders placed on or after March 20, 2018 Page 1 of 7

2 Numet Engineering shall notify OPG Buyer using the forms identified below, if any changes have or are to take place to the item shown in the purchase order item description which is assessed and qualified by OPG. Numet Engineering shall ensure contractual provisions and QA program requirements imposed on suppliers and sub-suppliers are such that Numet Engineering will be notified of any such changes that may occur within the supply chain. If any of these changes take place then Numet Engineering shall notify 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, Numet Engineering 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 the item. Although the Design Authority may solicit Numet Engineering s input to the decision, the decision of the Design Authority will be final. Numet Engineering is advised that: The items 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 items could be subjected to a harsh environment consisting of chemical and pressure transients, radiation, steam, and elevated temperature and pressure or submergence. It is possible that the design basis accident could occur at a time when the items have already been subjected to many years of normal operation and are nearing the end of their useful operating life. These items have been rigorously evaluated, and the OPG Engineer expects that they will perform their intended safety function following exposure to their harsh environment. OPG s Environmental Qualification Assessment (EQA) has established that the items may not perform their 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 these items. 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. 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 items ability to perform their intended safety function following a Design Basis Accident as even minor changes may dictate the need to retest or re-qualify the items. In any event, it will certainly dictate the need to evaluate the effect of the change to ensure that the new item will perform the same intended safety function as the items that were previously qualified. The "changes" referred to in this section are interpreted to mean any changes in materials of construction, changes in manufacturing processes that affect interchangeability, changes in form, fit and function, or any changes from the original design or performance requirements. Insignificant changes that do not affect any of these criteria (i.e. that do not result in a change in the item part number) are considered to be outside the scope of this requirement. 3.0 QUALITY ASSURANCE PROGRAM REQUIREMENTS For the EQ items that Numet Engineering manufactures/supplies to OPG, Numet Engineering shall implement, and maintain a QA program that provides assurance that the design, materials used in construction, methods used in fabrication/construction, non-destructive testing are such that, the Numet Engineering item both meets the design requirements, and is equivalent to the Numet Engineering item evaluated and EQ by OPG Engineer for use in nuclear safety applications based on the applicable primary controlled document(s). In order to provide this assurance Numet Engineering/Rolls-Royce Civil Nuclear Canada quality assurance program as audited/accepted by OPG shall meet the requirements of CSA CAN3-Z , or CSA N QA Standards including the requirement for product traceability. This clause applies to purchase orders placed on or after March 20, 2018 Page 2 of 7

3 Numet Engineering/Rolls-Royce Civil Nuclear Canada quality program as audited/accepted by OPG to the requirements of CSA CAN3-Z or CSA N QA Standards along with the requirements specified in the purchase order is acceptable to OPG to meet this requirement. Traceability is required by the contract, and therefore in accordance with CSA CAN3-Z or CSA N standards, Numet Engineering 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. 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 items shall be traceable to Numet Engineering/Rolls-Royce Civil Nuclear Canada audited location in Peterborough, Ontario. 4.0 INSPECTION AND TEST PLAN AND CRITICAL PROCESS PROCEDURE ACCEPTANCE In accordance with CSA CAN3-Z299.2/3-85 or CSA N299.2/3-16 QA standards, Numet Engineering shall prepare the Inspection and Test Plan (I&TP) document as part of the QA program requirements. A copy of the I&TP, signed by the authorized QA representative as a minimum, shall be submitted to OPG with shipment. However, OPG review and acceptance of the I&TP prior to proceeding with fabrication is only required when the Inspection and Test Plan Submission Requirement clause QA-I&TP is specified elsewhere in the OPG Contract P.O. This includes the situation for initial procurement of new items not previously manufactured & supplied to OPG. The OPG Engineer reserves the right to identify a list of special process and non-destructive examination procedures that must be submitted for acceptance prior to completing the work described on these procedures. It is agreed that OPG will not retain copies of these critical process procedures. Approved copies of these procedures are to be retained by Numet Engineering and Numet Engineering shall provide evidence that the work has been done in accordance with the approved procedures when called upon to do so by OPG s source inspector. The list will be identified at the time that the OPG Engineer reviews the Inspection and Test Plan. Numet Engineering shall make no significant change to the I&TP, critical process procedures, or NDT procedures without notification to, and acceptance from the OPG Engineer for those changes. The plan and associated procedures as well as any change/upgrade of the subject plan and associated procedures are to be submitted for approval 4 weeks prior to commencement of the work outlined on the plan or procedure. Numet Engineering should allow 3 weeks for approval. In the event that delay in receiving the OPG Engineer s review and acceptance will delay completion of the work, Numet Engineering is to notify OPG Buyer at least a week in advance of the delay occurring in order that OPG Buyer can expedite OPG Engineer review and acceptance and thus avoid the delay. If an expedited approval is required to meet the scheduled date of delivery, Numet Engineering is responsible for contacting the OPG Engineer to indicate the urgency and expedite the review and acceptance process. OPG Buyer will assist the Numet Engineering in this process. Notes: 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. This clause applies to purchase orders placed on or after March 20, 2018 Page 3 of 7

4 5.0 PRESSURE RETAINING ITEMS REGISTRATION WITH AUTHORIZED INSPECTION AGENCY Pressure retaining items are to be registered with an Authorized Inspection Agency (AIA). Piping systems shall be registered by technical standards & safety authority (TSSA), located in Ontario. Pressure vessels, storage vessels, pumps, valves, fittings or supports shall be registered as follows: By TSSA located in Ontario, or By Association of Chief Inspectors (ACI) central located in Prince Edward Island. ACI central provides registration for several Canadian provinces, including New Brunswick. As New Brunswick is the only one of these provinces that has nuclear class installations, registration shall be requested for the province of New Brunswick. Fittings are as defined in CSA N and update 2: clause and Table 1. 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 Numet Engineering shall provide evidence of that registration by way of a Canadian Registration Number (CRN) along with the shipment. For nuclear class 1, 2 or 3 components and materials, Numet Engineering shall supply items that meet the requirements of NCA 4000 (for components) or NCA 3800 (for materials). Additionally, in compliance with CAN/CSA-N & Update No. 2, Numet Engineering is to provide a History Docket which is to include at minimum: Statutory Declaration, Certified Material Test Report (CMTR) for SST housing material, Certificate of Compliance referencing serial numbers and applicable test data. The pumps are classified as ASME Section III Class 3. Rolls-Royce Civil Nuclear Canada Ltd has entered OEM partnership with Hayward Gordon Pumps to supply Hayward Gordon Pumps and associated spare parts. The CRNs provided for this product name will be under the name of the Rolls-Royce Civil Nuclear Canada Ltd. Therefore, Numet Engineering (part of Rolls-Royce Civil Nuclear Canada Ltd) is the Manufacturer of Record for these pumps. Code Reconciliation It is understood that the items to be installed in an ASME Section III Class 1, 2, or 3 applications will be manufactured in accordance with the latest revision of the ASME code in effect at the time of manufacture. Since Nuclear Power Plants have different applications and require that components be manufactured to different code effective dates as early as Numet Engineering will provide a code reconciliation statement which identifies any changes to the ASME code since the summer (addendum) of 1974 and shows that these changes have had no effect on the design of the component. If a change has occurred, refer to Section 2 for the corrective course of action that will be required. 6.0 SEISMIC QUALIFICATION REQUIREMENTS Numet Engineering shall demonstrate the seismic qualification for the item(s) is in accordance with the OPG Design/technical specification referenced in the OPG Purchase Order (P.O.) item description. Demonstration of the seismic qualification is permitted by physical testing and/or analysis. For repeated orders Numet Engineering s Certificate of Conformance statement that the item supplied is equivalent to that originally supplied by Numet Engineering (see Section Certification to Accompany Shipment ), is deemed to satisfy the OPG Engineer s requirement for seismic qualification of the item. 7.0 MARKING AND TAGGING OF THE ITEM 7.1 Complete pump 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).
