NRC Request (SSER 23 Appendix HH Item Number 108)

TVA should demonstrate to the NRC staff that there are no synergistic effects between temperature and humidity for the Common Q PAMS equipment. (SSER 23, Section 7.5.2.2.3.5.2, pg 7-75).

Follow-up NRC Request Upon review of the response to Action Item Number 94, it was noticed that TVA's response to these two action items provided different environmental conditions in each response (see Action Item Number 94 Clauses 4.5.3 and 4.7). It is no longer clear, in what environment the Common Q PAMS is required to operate or how qualification to this environment is demonstrated.

a. Please provide EPM-MCP-071689, "Cooling/Heating Load & Equipment/Component Performance Analysis for the Control Building Electrical Board Room Areas (EL. 692.0 and 708.0)," Revision 19.

b. Please provide EPM-LCP-072489, "Cooling and Heating Load Analysis, Main Control Room HVAC [Heating, Ventilating, and Air Conditioning]," Revision 13.

c. Please provide the maximum temperature and the associated maximum relative humidity in which the Common Q PAMS is required to be operable.

d. Please provide the minimum temperature and the associated minimum relative humidity in which the Common Q PAMS is required to be operable.

e. Please explain why the relative humidity during a loss of coolant accident event is lower than the humidity during summer or winter.

f.

Please describe how it is demonstrated that the Common Q PAMS equipment is qualified to the environments in which that equipment is required to operate. Please pay particular attention to the potential synergistic effects of temperature and humidity.

TVA Partial Response to Follow-up NRC Request Responses to Draft Request for Additional Information Regarding Open Item 108, items a through e were provided in TVA to NRC letter dated December 22, 2011 (Reference 1).

Item f is addressed as follows:

f.

It is not possible to state whether or not there are any synergistic effects between temperature and humidity on the Common Q PAMS equipment. The NRC-approved qualification methods in WCAP-16097-P-A, Common Qualified Platform Topical Report, Revision 0, do not perform or require such testing. What can be shown is that the WBN Unit 2 operating conditions are bounded by the Common Q PAMS hardware qualification testing.

E1-2 TVA Letter Dated January 19, 2012 TVA Responses to Instrumentation and Controls Staff Information Requests describes how the Common Q PAMS equipment is qualified for the environments in which it is required to operate.

E1-3 TVA Letter Dated January 19, 2012 TVA Responses to Instrumentation and Controls Staff Information Requests Review of the GA-ESI qualification reports found that the seismic Test Response Spectra (TRS) did not bound the WBN Required Response Spectra (RRS). Engineering performed an analysis of the differences and determined that the GA-ESI qualification testing was acceptable. The analysis is documented in TVA calculation WCGACQ0766. 1 contains TVA calculation WCGACQ0766, Required Response Spectra for Evaluation of Radiation Monitoring Equipment, Revision 1.
