Section 2.3.3.7, Compressed Air System Question RAI 2.3.3.7-1 (Unit 2)
On license renewal drawing 2-34-2, the applicant highlights piping from the standby instrument air train that supplies backup containment instrument air as being within the scope of license renewal. The applicant highlights a 1-inch branch line to valve 614 in the Cable Vault Building at location F-5, which has a continuation arrow and note, indicating that it supplies downstream components in the containment penetrations cubicle. Also, the applicant highlights a 1-inch branch line and a 3/4-inch branch line in the Auxiliary Building at location E-10, which have continuation arrows, indicating they supply some downstream components. The staff is unable to confirm which components are within the scope of license renewal and subject to an aging management review downstream of these continuation lines.
Describe the components that are connected by the 3/4-inch and two 1-inch compressed air branch lines and their intended function or provide a copy of the continuation drawings for these branch lines identifying the components to be included within the scope of license renewal, as appropriate.
RESPONSE RAI 2.3.3.7-1 (Unit 2)
The highlighted flowpath downstream of instrument air system valve 21AS-614 (in the containment penetrations cubicle) terminates at Chemical and Volume Control System (CVCS) letdown isolation valve 2CHS-AOV204. The two highlighted branch lines I downstream of valves 21AS-648 and 21AS-645 on LR Drawing 2-34-2, grid E-10, supply control air to CVCS charging flow control valve 2CHS-FCV1 22 and CVCS letdown backpressure control valve 2CHS-PCV145, respectively. Piping and valves in the air supply flow paths to 2CHS-AOV204, 2CHS-FCV122 and to 2CHS-PCV1 45, as well as branch lines from the flow paths up to and including the first isolation valve, are within the scope of License Renewal and are subiect to aging management review.
Attachment L-08-227 Page 2 of 2 Unit 2 relies upon compressed air for operation of selected valves to achieve safe shutdown following a fire in a specific area within containment. The flowpaths that utilize these air-operated valves are associated with CVCS charging and letdown, Residual Heat Removal System flow and temperature control, and Primary Component Cooling Water System supply to the reactor coolant pump thermal barrier heat exchangers.
The air supplies to the remaining air operated valves (other than 2CHS-AOV204, 2CHS-FCV122 and 2CHS-PCV145) used to achieve safe shutdown are shown terminating at the associated valve operators on LR Drawing 2-34-10.
