$0NTAINMENTSYSTEMS CONTAINMENT STRUCTURAL INTEGRITY LIMITING CONDITIONS FOR OPERATION i 3.6.1.6 The structural integrity of the containment shall be maintained at a level consistent with the acceptance criteria in Specification i 4.6.1.6. ,

APPLICABILITY: MODES 1, 2, 3 and 4.

ACTION:

  • With the structural integrity of the containment not conforming to the above requirements, restore the structural integrity to within the limits within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> 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 />.

SURVEILLANCE RE0VIREMENTS 4.6.1.6.1 Containment Tendons The containment tendons', anchorages and adjacent concrete surfaces, structural integrity shall be demonstrated in accordance with ASME,Section XI, Subsection IWL.

The requirements of IWL-2521 and IWL-2521.1 are exempted. The provisions of Specification 4.0.2 are applicable to containment tendons surveillance.

4.6.1.6.2 Containment Surfaces 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 \erify no apparent changes in appearance or other abnormal degradation.  ;

4.6.1.6.3 Containment Dome The containment dome's structural integrity shall be demonstrated at the end of 1 year, 18 months, 2 years, 3 years, 40 10 months (coincident with the first periodic integrated containment leak rate test), and 5 years following the initial containment structural integrity test. The dome's structural integrity shall be demonstrated by:
