APPLICABILITY: MODES 1, 2, 3 and 4.

ACTION:

Without primary CONTAINMENT INTEGRITY, restore CONTAINMENT INTEGRITY within one hour or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />, c SURVEILLANCE REQUIREMENTS 4.6.1.1.1 Primary CONTAINMENT INTEGRITY shall be demonstrated:

a. At least once per 31 days by verifying that:
1. All penetrations
  • not capable of being closed by OPERABLE containment automatic isolation valves and required to be closed during accident conditions are closed by valves, blind flanges, or deactivated automatic valves secured in 1 their positions, except those valves that may be opened i under administrative controls per Specification 3.6.3.1, and
2. All equipment hatches are closed and sealed. '
b. By verifying that each containment air lock is OPERABLE per. ,

Specification 3.6.1.3. -

4.6.1.1.2 The structural integrity of the exposed accessible interior and -

exterior surfaces of the containment, including the liner plate, shall be determined during the shutdown for each Type A containment leakage rate test (Specification 4.6.1.2) by a visual inspection of these surfaces.

This inspection shall be performed prior to the Type A containment leakage rate test to verify no apparent changes in appearance or other abnormal.

degradation.

  • Expect valves, blind flanges, and _ deactivated automatic valves which are located inside the containment and are locked, sealed, or otherwise secured j in the closed position. These penetrations shall be verified closed during each COLD SHUTDOWN except that verification of these penetrations being <

closed need not be performed more often than once per 92 days. I CRYSTAL RIVER - UNIT 3 ,m 3/4 6-1 Amendment No.

3.6.1.6 The structural integrity of the containment shall be maintained at  !

a level consistent with the acceptance criteria in Specification 4.6.1.6.  :

APPLICABILITY: MODES 1, 2, 3, and 4. .

'l ACTION:

With the structural integrity of the containment not conforming to the above requirements, restore the structural integrity to within the limits. .

4.6.1.6.1 Verify containment structural integrity in accordance with the Containment Tendon Surveillance Program. The frequency shall be in accordance with the Containment Tendon Surveillance Program.

4.6.1.6.2 Any abnormal degradation of the containment structure detected R during the tests required by the Containment Tendon Surveillance Program shall be reported to the Commission within 30 days. The report shall include a description of the tendon condition, the condition of the  :

concrete (especially at tendon anchorages), the inspection procedures, the tolerances on cracking, and the corrective action taken.

CONTAINMENT SYSTEMS l RAWM 3/4.6.1.4 INTERNAL PRESSURE The limitations on containment internal pressure ensure that 1) the containment structure is prevented from exceeding its design negative pressure differential with respect to the outside atmosphere of 3.0 psig and 2) the containment peak pressure does not exceed the design pressure of 54.6 psig during LOCA conditions.

-The maximum peak pressure obtained from a LOCA event is 50.3 psig. The limit of 3 psig for initial positive containment pressure will limit the total maximum peak pressure to 53.3 psig which is less than the design pressure and is consistent with the safety analysis. '

3/4.6.1.5 AIR TEMPERATURE The limitations on containment average air temperature ensure that the overall containment average air temperature does not exceed the initial temperature condition assumed in the accident analysis for a LOCA. ,

3/4.6.1.6 CONTAINMENT STRUCTURAL INTEGRITY This limitation ensures that the structural integrity.of the containment will be maintained comparable to the original design standards for the life  :

of the facility. Structural integrity is required to ensure that the containment will withstand the maximum pressure of 53.3 psig in the event of a LOCA. The testing addressed within Regulatory Guide 1.35, Revision 3, is sufficient to demonstrate this capability.
