16.10 STEAM AND POWER CONVERSION SYSTEM Obg 16.10.2 STEAM VENT TO ATMOSPHERE COMMITMENT:
Four steam generator PORV safety-related gas supply systems shall be OPERABLE with both nitrogen bottles per S/G PORV, pressurized to greater than or equal to 2100 psig.
APPLICABILITY:
Modes 1, 2, 3, 4*
REMEDIAL ACTION:
a.
With one nitrogen bottle on one or more S/Gs less than 21-psig, immediately start corrective action to return the nitrogen supply to OPERABLE. Work to return the nitrogen supply to OPERABLE status should continue without interruption.
b.
With two nitrogen bottles on one or more S/Gs less than 2100 psig, O
consider the PORV(s) inoperable and refer to Technical Specification v
3.7.1.6 for the required action.
TESTING REQUIREMENTS:
At least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> by verifying that both nitrogen bottles per S/G PORV has a pressure greater than or equal to 2100 psig.

BASES:
Design Engineering calculation CNC-1223.43-01-0011, rev 1, demonstrates that with one nitrogen bottle charged to at least 2100 psig, sufficient nitrogen exists to meet the Tech Spec Design basis of the S/G PORVs.
A revision to calculation CNC-1223.43-01-0011 also demonstrates that with two nitrogen bottles charged to as least 2100 psig, sufficient nitrogen exists to meet the Branch Technical Position RSB5-1 of supporting a controlled cooldown to the point where residual heat removal system can be put in service with or without offsite power following an earthquake.
The COMMITMENT for having both nitrogen bottles pressurized to greater than or equal to 2100 psig and the REMEDIAL ACTION, is adequate to ensure the intent of our FSAR commitment to Branch technical Position RSB5-1 is met.
