1 1.0 QUALIFICATION BY ANALYSIS This EQPR is intended to be used when buying Anderson Greenwood Crosby brand pressure relief valves manufactured by Pentair/Anderson Greenwood Crosby to Ontario Power Generation (hereinafter OPG) for use throughout its nuclear sites in safety-related applications which require being environmentally qualified (EQ). OPG Engineer (see the Contract Standard for definition of Engineer ) generally assesses and qualifies electrical equipment for use in EQ applications 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 replicated and verified. These critical characteristics may be shown on one or more of a number of different documents including the manufacturer s catalogue, manufacturer s drawing(s), test reports, 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. 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 OPG purchase order (P.O.) 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 P.O. item description. Pentair/Anderson Greenwood Crosby is advised that the following item has been assessed and environmentally qualified by the OPG Engineer for use in nuclear safety-related applications based on the primary controlled documents as listed below. Anderson Greenwood Crosby model 83CF48-6L pressure relief valve with the following age-sensitive EQ critical components: Viton seat (O-ring), Viton bushing seal, Viton seal for blowdown adjustment screw or plug as described in Anderson Greenwood Crosby Drawing: C98697 (corresponding OPG drawing: NA44-DRAW ). All the items and spare parts are to be supplied in accordance with the requirements on the approved drawing(s) and OPG Design/Technical specifications referenced in the OPG P.O. item description. 2.0 CHANGES IN DESIGN AND SUBSTITUTION OF QUALIFIED MATERIALS Changes made to the Pentair/Anderson Greenwood Crosby items that were originally assessed and environmentally qualified by OPG are to be tracked. Pentair/Anderson Greenwood Crosby 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 are not deemed to be reported to the client (since fit, form, and function are met), can invalidate the equipment qualification. Changes to nonmetallic components are of particular interest to OPG. Pentair/Anderson Greenwood Crosby shall notify the OPG Buyer using the forms identified below, if any changes have or are to take place to the item shown in the OPG P.O. item description, which is assessed and qualified by OPG. This clause applies to purchase orders placed on or after March 20, 2018 Page 1 of 6

2 Pentair/Anderson Greenwood Crosby shall ensure contractual provisions and QA program requirements imposed on suppliers and sub-suppliers are such that Pentair/Anderson Greenwood Crosby shall be notified of any such changes that may occur within the supply chain. If any of these changes take place then Pentair/Anderson Greenwood Crosby 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, Pentair/Anderson Greenwood Crosby 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 shall 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 Pentair/Anderson Greenwood Crosby s input to the decision, the decision of the Design Authority shall be final. Pentair/Anderson Greenwood Crosby is advised that: The items will be installed in a nuclear safety system. That system shall 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 shall perform their intended safety function following exposure to this 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. 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 shall certainly dictate the need to evaluate the effect of the change to ensure that the new item shall 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 Pentair/Anderson Greenwood Crosby manufactures and supply to OPG, Pentair/Anderson Greenwood Crosby shall implement and maintain a quality assurance program that provides assurance that the design, materials used in construction, methods used in fabrication/construction, non-destructive testing, are such that the Pentair/Anderson Greenwood Crosby item both meets the design requirements and is equivalent to the Pentair/Anderson Greenwood Crosby item evaluated and qualified by OPG Engineer. This clause applies to purchase orders placed on or after March 20, 2018 Page 2 of 6

3 In order to provide this assurance Pentair/Anderson Greenwood Crosby QA program/manual as audited/accepted by OPG shall meet the requirements of CSA CAN3-Z , or CSA N QA standards, including the requirement for material traceability. Traceability is required by this contract, and therefore in accordance with CSA standards CAN3-Z299.1/2/3-85 or CSA N299.1/2/3-16, Pentair/Anderson Greenwood Crosby 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. 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 an authorized registrar (i.e. ASME, TSSA, other Canadian provincial jurisdiction) shall be required, in accordance with the CSA N285.0 standard. Any item sourced from any other facility shall be dedicated by Pentair/Anderson Greenwood Crosby using suitable EPRI methodology, under the Pentair/Anderson Greenwood Crosby s QA program as audited/accepted by OPG. All items shall be traceable to Pentair/Anderson Greenwood Crosby plant located in Mansfield, Massachusetts. 4.0 INSPECTION AND TEST PLAN AND SPECIAL PROCESS PROCEDURE ACCEPTANCE In accordance with CSA CAN3-Z299.2/3-85 QA standards, Pentair/Anderson Greenwood Crosby shall prepare the Inspection and Test Plan (I&TP) document as part of the QA program requirements. A copy of the completed I&TP, signed by the authorized QA representative as a minimum, shall be submitted to OPG with the shipment. However, OPG review and acceptance of the I&TP prior to initiating the work is required only 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 and supplied to OPG. OPG Engineer reserves the right to identify a list of special process and non-destructive examination procedures that shall 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 Pentair/Anderson Greenwood Crosby and Pentair/Anderson Greenwood Crosby 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. Pentair/Anderson Greenwood Crosby 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. 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 OPG acceptance for changes will in turn delay completion of the work Pentair/Anderson Greenwood Crosby is to notify the OPG s Buyer at least one week in advance of the expected delay; in order that OPG Buyer can expedite OPG Engineer acceptance and thus avoid said delay. OPG reserves the right to review these during QA program audit or contract specific inspections in order to satisfy itself that manufacturing and inspection activities are appropriately planned, authorized and controlled. Pentair/Anderson Greenwood Crosby critical process procedures and ITP shall be available for audit by OPG source inspectors. 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. This clause applies to purchase orders placed on or after March 20, 2018 Page 3 of 6

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 Pentair/Anderson Greenwood Crosby shall provide evidence of that registration by way of a Canadian Registration Number (CRN) along with the shipment.
