SUBJECT:
ADVANCE COPY OF REVISED AP600 TECIINICAL SPECIFICATION 3.7.6
Reference:
1.
NSD-NRC-97-5029 (DCP/NRC0776), " Response to Some of the Technical Specification Comments from NRC Letter of 12/24/96," dated 3/27/97.
Dear Mr. Quay:
Attached is a markup of AP600 Technical Specification 3.7.6, Main Control Room IIabitability System. These changes resolve comments discussed during a 5/9/97 telecon involving Messrs.
Iluffman, Raval, and Walker of the NRC and Messrs. Suggs, Wills, and McDermott and Ms. Nydes of Westinghouse. During this telecon, we discussed the Reference 1 NRC comment and Westinghouse response for item 31, as well as a markup provided by the NRC via fax on 5/8/97.
The changes are described as follows.
(
l.
To address the NRC concern regarding LCO 3.7.6 applicability in MODE 4 and the REQUIRED ACTIONS (D.2 and F.2) leading to MODE 4, a markup of the LCO and BASES is attached. The action for D.2 is now to go to MODE 5 while the action for F.2 is to restore one VES train to OPERABLE status. Westinghouse believes this resolves the MODE 4 applicability /endstate issue for LCO 3.7.6.
- 2. The main control room (MCR) air temperature for SR 3.7.6.1, and in the BACKGROUND section, is changed to the nominal value of 78 F (from 80 F).
- 3. The APPLICABLE SAFETY ANALYSIS discussion of the safety signals which actuate the MCR habitability system (VES) has been clarified to include Iligh-2 particulate or iodine radioactivity.
4.
Although during the 5/9/97 telecon, the approach was to revise the BASES for SR 3.7.6.2 to include the compressed air storage tank maximum pressure, it has since been discovered by 1
Westinghouse that a precedent for bottled air exists in the North Anna and Beaver Valley Technical SpeciGcations. Following this precedent, specification of a maximum pressure is deleted from AP600 Technical Specification SR 3.7.6.2.

NSD-NRC-97-5130 DCP/NRC0866 May 19,1997 5.
The BASES for SR 3.7.6.9, regarding the VES air delivery train test has been revised to include a pressure and flow rate, as well as a more detailed discussion regarding the duration of the test.
SECY-95-132 was added as a reference for this revision.
l
- A markup of SSAR page 3.9-168 Note 8 is also included to incorporate the pressure and flow rate of SR 3.7.6.9.
Item 5250 was added to the Open Item Tracking System (OITS) to track completion of Technical Specification 3.7.6. While this submittal completes the Action -W portions of OITS item 5250, two actions remain:
- g. NRC to confirm acceptance of MODE APPLICABILITY for LCO 3.7.6.
j l
- h. NRC to determine acceptability of the damper surveillance frequencies SRs 3.7.6.5 and 3.7.6.7.
In addition, although not a Technical Specification issue, during the telecon, Westinghouse took an action to determine the status of developing the sampling program which will include air storage tank air quality testing. This action has been logged as OITS item 5251.
This markup is our submittal of LCO 3.7.6 and constitutes completion consistent with the schedular objectives of SECY-97-051 for Westinghouse to provide the NRC with final submittals, including the I
AP600 Technical Specifications in SSAR Section 16.1, by 5/30/97. The NRC is requested to provide:
- 1. concurrence with (or comments on) the attached markups,
- 2. completion of NRC action for OITS item 5250 parts g and h, and 3.
an NRC status revision for an OITS update of 5250.
Please contact Robin K. Nydes at (412)374-4125 if you have any questions regarding this transmittal l
or the AP600 Technical Specifications.
