| Issue: The staff has determined that the concept of a "collapse envelope" is not addressed in NEI 95-10, Appendix F, as a basis for not including fluid filled non-safety related SSCs, in the proximity of safety-related SSCs, within the scope of license renewal. In addition, during the NRC scoping and screening methodology audit performed March 10-13, 2009, the staff performed a walkdown of two nonsafety-related systems, in the proximity of safety-related SSCs, which were not included within the scope of license renewal based on the concept of the collapse envelope. The staff determined that in addition to the use concept of the collapse envelope there were additional mitigative features not discussed in the LRA (dikes and enclosures). | | Issue: |

NS components containing or potentially containing moderate or low energy fluids (i.e.,
200°F or 275 psig) were also included in license renewal scope unless both 2(a) and 2(b) below applied:
(a) The NS component could not directly leak or spray on SR components in the immediate area because one of the following conditions existed:
- The NS component was located in a room, cubicle, enclosure, tunnel, or enclosed corridor, which did not contain any SR mechanical or electrical components.
- The NS component was located in an open space, but was separated from SR mechanical or electrical components by solid physical barriers such as walls, floors, ceilings and/or major plant equipment (e.g., the main condenser).
- The NS component was located in an open space, was maintained at or near atmospheric pressure, and there were no SR mechanical or electrical components located within the collapse envelope of the NS component.
(b) The fluid contents of the NS components could not flow from the area through doorways, grating, or floor penetrations, and then drain or drip on or flood SR mechanical or electrical components in adjacent areas, unless an analysis demonstrated that the SR components would not be adversely impacted.
ENCLOSURE
Issue:
The staff has determined that the concept of a collapse envelope is not addressed in NEI 95-10, Appendix F, as a basis for not including fluid filled non-safety related SSCs, in the proximity of safety-related SSCs, within the scope of license renewal. In addition, during the NRC scoping and screening methodology audit performed March 10-13, 2009, the staff performed a walkdown of two nonsafety-related systems, in the proximity of safety-related SSCs, which were not included within the scope of license renewal based on the concept of the collapse envelope.
The staff determined that in addition to the use concept of the collapse envelope there were additional mitigative features not discussed in the LRA (dikes and enclosures).
Request:
The staff requests that the applicant provide a discussion which states that an exception was taken to guidance of NEI 95-10 and provide the basis for the exception (the collapse envelope),
for not including nonsafety-related SSCs, within the proximity of safety-related SSCs, within the scope of license renewal. The discussion should include a definition of collapse envelope and the rationale for the application of the collapse envelope as the basis to not include specific nonsafety-related SSCS within the scope of license renewal. In addition, discuss the use of any mitigative features used in conjunction with the collapse envelope and whether the mitigative features were included within the scope of license renewal in accordance with 10 CFR 54.4(a)(2).
As part of your response, please address the extent of condition - the number and location of nonsafety-related SSCs, within the proximity of safety-related SSCs but not within the scope of license renewal in accordance with 10 CFR 54.4 (a)(2), based on the concept of a collapse envelope and any associated mitigative features. Indicate whether any associated mitigative features were included within the scope of license renewal.
List any additional SSCs which were included within the scope of license renewal as a result of your review performed in response to this RAI and list those structures and components for which aging management reviews were conducted. For each additional structure and component, describe the aging management programs, as applicable, to be credited for managing the identified aging effects.
