Comments on Relations Among TSTFs, RCOL Std. Dep., RCOL COL Items, and RCOL PTS Changes This section discusses the considered changes that are: (1) applicable to operating reactor designs, but not to the AP1000 design; (2) already incorporated in the GTS; or (3) superseded by another change.
VEGP LAR DOC M13 revises TS 3.6.6 to incorporate TS 3.6.7 and deletes the GTS 3.6.7.
Changes applicable to TS 3.6.7 are incorporated into TS 3.6.6. Changes VEGP LAR DOC A086, VEGP LAR DOC A087, and VEGP LAR DOC D06 are applicable to both TS 3.6.7 and TS 3.6.6. Change VEGP LAR DOC L14 is applicable to TS 3.6.7 and is incorporated into TS 3.6.6 as part of change VEGP LAR DOC M13. Due to the change described above, GTS 3.6.8, GTS TS 3.6.9, and GTS TS 3.6.10 are renumbered as TS 3.6.7, TS 3.6.8, and TS 3.6.9, respectively.

Traveler Information Description of TSTF changes:
None Rationale for TSTF changes:
None Description of changes in RCOL Std. Dep., RCOL COL Item(s), and RCOL PTS Changes:
VEGP LAR DOC M13 revises TS 3.6.6 to incorporate TS 3.6.7 and deletes TS 3.6.7. The Applicability for TS 3.6.6 is revised to include a new Applicability of "MODES 5 and 6 with the reactor decay heat > 6.0 MWt." TS 3.6.6 Condition D, first Condition, is revised to include the phrases "of Condition A, B, or C," and "in MODE 1, 2, 3, or 4." TS 3.6.6 Condition D, second Condition, is revised to include the phrase "in MODE 1, 2, 3, or 4." TS 3.6.6 Actions E and F are added.
Rationale for changes in RCOL Std. Dep., RCOL COL Item(s), and RCOL PTS Changes:
VEGP LAR DOC M13 change to incorporate TS 3.6.7 into TS 3.6.6 results in a more restrictive TS since it eliminates the separate restoration times when in Mode 5 or 6. Also, TS 3.6.6 and TS 3.6.7 have identical LCO statements.

Tuesday, May 12, 2015 Page 7 VII. GTST Safety Evaluation Technical Analysis:
VEGP LAR DOC M13: GTS 3.6.6, Passive Containment Cooling System (PCS) - Operating and GTS 3.6.7, Passive Containment Cooling System (PCS) - Shutdown have the identical LCO statements. Thus, the two Specifications are combined into a single Specification. For Shutdown the "Applicability" statement is revised to include MODES 5 and 6 with the reactor decay heat > 6.0 MWt. GTS 3.6.7 Actions A, B, and C are identical to GTS 3.6.6 Actions A, B, and C. GTS 3.6.6 Condition D, is revised to specify the applicable Conditions and Modes by including the phrases "of Condition A, B, or C," and "in MODE 1, 2, 3, or 4." TS 3.6.6 Condition D, second Condition, is revised to specify the applicable Modes by including the phrase "in MODE 1, 2, 3, or 4." Action D of GTS 3.6.7 is separated into two individual Actions E and F in TS 3.6.6. The Surveillance Requirements for GTS 3.6.7 refers to the GTS 3.6.6 SRs as being applicable. Combining the GTS 3.6.6 and GTS 3.6.7 into a single new TS 3.6.6 is more restrictive due to the elimination of the separate restoration times when in Mode 5 or 6. This potential reduction in restoration time is acceptable, since the Passive Containment Cooling System has already been inoperable for at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> prior to entering Mode 5.

The AP1000 GTS 3.6.7 is for Passive Containment Cooling System (PCS) - Shutdown and is APPLICABLE in MODES 5 and 6 with the calculated reactor decay heat > 6.0 MWt. There is no equivalent Specifications in NUREG-1430 or NUREG-1431.
The AP1000 GTS 3.6.7 Passive Containment Cooling System (PCS) - Shutdown, and associated basis are shown in the Westinghouse AP1000 Design Control Documents

APOG Comments (Ref. 6) and Resolutions:
- 1.
(Internal #6) The GTST sections often repeat VEGP LAR DOCs, which reference existing and current requirements. The inclusion in the GTST of references to existing and current, are not always valid in the context of the GTS. Each occurrence of existing and current should be revised to be clear and specific to GTS, MTS, or VEGP COL TS (or other), as appropriate. This is resolved by making the APOG recommended changes to the GTST.
