ENCLOSUREI Response to RAIs Necessary to Complete Supplement 22 to the Watts Bar SER Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 Qualification Methods 3.11 - EQ- 1. In its FSAR amendments and supplemental letters, TVA stated that qualification tests and analyses for safety-relatedelectrical equipment were conducted in accordancewith the requirements of 10 CFR 50.49 and the guidelines of NUREG-0588, Revision 1. In NUREG-0588, Revision 1, the NRC staff presents detailedprocedures for qualifying safety-relatedelectrical equipment in a harsh environment. The NUREG-0588 criteriaapply to equipment that is importantto safety as defined in 10 CFR 50.49.
The staff concluded that the qualificationmethods used by TVA are consistent with NRC regulationsand are, therefore, acceptable. However, based on the extensive layup period of equipment within WBN Unit 2, the NRC staff must review, priorto fuel load, the assumptions used by TVA to re-establisha baseline for the qualified life of equipment. The purpose of the staffs review is to ensure that TVA has addressedthe effects of environmental conditionson equipment during the layup period.
Pleaseprovide the assumptions used by TVA to re-establish a baseline for the qualified life of equipment based on the extensive layup period of equipment within WBN Unit 2.
Response: For WBN Unit 2 equipment and cables that are not being replaced prior to startup, the layup period will be addressed in the qualified life evaluations. Engineering defines the service temperature and radiation dose conditions for the period following installation and prior to Unit 2 startup. The aging that occurred during this pre-operational period will be addressed in the qualified life calculations.
For the Reactor Building and Main Steam Valve Vault, the temperature will be assumed to be 1000 F for conservatism (Calculation MDQ00200020100374, Unit 2 Layup Temperatures inside Reactor Building and MainSteam Valve Vault, has shown the value to be less than 1000 F). All other areas are per the environmental drawings.
For all areas except the Reactor Building, the radiation dose will be assumed to be 1.5 times the normal 40 year dose for conservatism (the actual layup period from Unit 1 criticality to Unit 2 startup will be significantly less than 20 years). For the Reactor Building, the normal dose per the environmental drawings would be unreasonably high; thus, a conservative value of 1.5 times the normal 40 year dose of the Annulus is assumed (this is significantly higher than the actual dose since no dose source is present inside the Unit 2 Reactor Building during the layup period).

ENCLOSUREI Response to RAIs Necessary to Complete Supplement 22 to the Watts Bar SER Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 For cables which were installed during the layup period from Unit 1 criticality to Unit 2 startup, consideration is given to additional heat rise due to energized Unit 1 cables. Engineering will document applicable cases for input to the qualified life evaluations.
Electrical Equipment in a Harsh Environment 3.11 - EQ - 2. Please provide TVA's EQ programprocedures for WBN Unit 2.
Response: The EQ program procedures for WBN Unit 2 are:
0 25402-3DP-GEE-00001, Rev. 0, "Equipment Environmental Qualification (EQ) Program"; and
- 25402-000-GPP-0000-NI 106, Rev. 3, "Equipment Environmental Qualification."
These procedures were created for the construction phase of Unit 2 based on the existing Unit 1 EQ program to implement the equivalent requirements. Upon completion of construction, the Unit 1 procedures will be the governing documents.
Attachment 1 provides copies of the two procedures.
3.11 - EQ - 3. The NRC staff requested TVA confirm that equipment being replacedor refurbished will be qualified as Category I, as required by 10 CFR 50.49. In its response dated September 1, 2010, TVA stated that "replacedequipment is being procuredqualified to the NUREG-0588, Category I requirements." TVA also stated, however, that a small population of components is being refurbished. The NRC staff reviewed these components as noted below.
- a. All 6.9 kV motors will be refurbished TVA considers the refurbishment activities to be routine maintenance that do not impact the qualification of the motors. The staff considers that routine maintenance activities should result in increasingthe EQ of the motors to Category I status in accordance with 10 CFR 50.49. Pleasejustify refurbishment of all 6.9 kV motors impact on EQ.
Response: The refurbishment of the 6.9 kV motors for Unit 2 involves routine maintenance activities. These maintenance activities do not modify the Category II motor insulation system originally supplied by Westinghouse. Motors which only require routine maintenance will remain Category II qualified.
In some cases, the maintenance activities determine the need to rewind the motor. The rewound motor insulation system will be qualified in accordance with the EPRI motor rewind program which meets Category I criteria. Motors which El -2
ENCLOSURE1 Response to RAIs Necessary to Complete Supplement 22 to the Watts Bar SER Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 require a rewind will be Category I qualified. Currently, one of the Unit 2 Containment Spray pump 6.9 kV motors is being rewound to repair insulation damage.
- b. Terminal Blocks TVA stated that it noted during a field walkdown that the terminalblocks installedin the EQ application for WBN Unit 2 are GE-make CR151B.
According to TVA, these terminal blocks are qualified to NUREG-0588, Category I. VA further noted that design modifications have been issued to inspect and replace the EQ terminalblocks that are found damaged or degraded with equivalent CR151B blocks.
Please clarify the use of the term "equivalent"(e.g., identical, similar) regardingthe replacementterminal blocks. If the blocks are similar,please complete a similarity analysis and provide it to the NRC staff for review.
Response: For EQ applications, the replacement terminal blocks will be new GE CR151B terminal blocks certified to test reports that document qualification to NUREG-0588, Category I criteria.
TVA stated that the original WBN Unit 2 MSIVs are qualified to NUREG-0588, Category II. The MSIVs are being refurbished by replacing the missing subcomponents, including the solenoid valves, terminalblocks and manufacturing wiring, with components of the same make, model, and type as supplied on the originalpurchase order. With the exception of the solenoid valves, the subcomponents will be qualified to NUREG-0588, Category I requirements. According to TVA, the solenoid valves cannot be upgraded because equivalent subcomponents qualified to NUREG-0588, Category I requirements are not available.
Pleasejustify not upgrading the MSIV solenoid valves to CategoryI in light of 10 CFR 50.49(l).
Response: 10 CFR 50.49(l) requires replacement equipment to be qualified in accordance with 10 CFR 50.49 unless there are sound reasons to the contrary. Regulatory Guide 1.89 (Revision 1), paragraph C.6.d indicates that one of the sound reasons for not upgrading replacement equipment is that replacement equipment qualified in accordance with the provisions of 10 CFR 50.49 does not exist. The MSIV supplier (Weir) has indicated that replacement solenoids qualified in accordance with the provisions of 10 CFR 50.49 are not available for the Unit 2 MSIVs.

ENCLOSUREI Response to RAIs Necessary to Complete Supplement 22 to the Watts Bar SER Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 Mild Environment 3.11 - EQ - 4. The NRC staff requested that TVA clarify that, for a mild environment, the threshold for electronic components such as semiconductorsor electronic components containing organicmaterialis a total integrateddose of less than lx 103 Rads, and that a threshold for a mild radiationenvironment for other equipment is less than 1x10 4 Rads. In its response dated August 30, 2010, TVA stated that the upper threshold for the EQ Mild Environment is 1x10 4 Rads for all components, which is consistent with WBN Unit 1. Since certain components may have a lower threshold for impacts from radiation exposure, TVA stated that it requires the following at WBN:
Per design standards,any device, whether in a mild, essentially mild, or harsh environment, is requiredto be purchased to the environmental conditions where it is to be located. That includes the usual radiation,temperature, humidity, etc. guidelines. An environmental conditions data sheet with the stated environmentalparametersis sent to the manufactureralong with the purchase request and [TVA asks] the vendor to meet those conditions.
ForMOS [metal oxide semiconductors], CMOS or like circuitry, the same holds true. But, the design standardfor qualification of electrical equipment in a harsh environment specifically requiresthat any of this type circuitry be evaluated on a case-by-case basis for any gamma dose exceeding 1xi03 Rads.
Please provide supporting documentationto justify TVA's establishment of a mild environment threshold for total integrateddose of less than Ix103 Rads for electronic components such as semiconductors or electronic components containing organic material.
Response: Note: NRC verbally provided the clarification that "lx104 Rads" was the intended value in the last paragraph of the request.
In order to establish the upper threshold cutoff value for radiation levels in EQ Mild Environments, TVA did an analysis of a pertinent segment of available literature on radiation effects on both individual electronic components and electronic component assemblies. The literature was primarily EPRI documents, articles published in the IEEE Transactions on Nuclear Science, Radiation Effects Research Institute (REIC) reports, and other industry publications (References 1 through 17). The publications addressed both organic and inorganic materials. TVA concluded that typical, non-selected electronic components will, with certain notable exceptions, tolerate a total integrated radiation dose of greater than 5x1 04 Rads without significant degradation of their performance. Based on this analysis, TVA established a radiation cutoff for mild environments of lx104. Rads. The evaluation of the "notable exceptions" (e.g., metal oxide semiconductors) was El -4
