2. Pressure tests are conducted each outage with one extra test performed during the third period.

3. Pressure tests are conducted once each period, so each test wlI normally be conducted three times over the interval. The exception is in the Component Cooling system, which was split into two tests during the second period, resulting in five tests instead of six tests.

4 For pressure tests, the total number of test per period are calculated by taking the number of tests completed for the period divided by the number required for the period.

5. Limited examinations will be submitted to the NRC for reliefin accordance with 10 CFR 50.55a.
