LIMITING CONDITIONS FOR OPERATION SURVEILLANCE REQUIREMENTS

'3.7 A'(Cont'd) 4.7.A.2.f (cont'd)

I 4. Main steam line and feedwater line s expansion bellows as specified in -l Table 3.7.3 shall be tested by {

pressurizing between the laminations l

('

of the bellows at a pressure of 5 psig. )

This is an exemption to Appandix J of 10CFR50.

5. The personnel airlock shall be tested at 58 psig at intervals ~no '

longer than six months. This testing may be extended to the next refueling outage (not.to exceed 24 months) provided that there have been no airlock openings since the last successful test at 58 psig. In the event the personnel airlock is not opened between refueling outages, it shall be leak checked at 3 psig at intervals no longer than Fix months.

Within three days of opening (or-l every three days during periods of i frequent opening) when containment integrity is required, test the personnel airlock at 3 psig. This is an exemption to Appendix J of 10CFR50.

The maximum allowable leakage at a test pressure of 58 psig is 12 scfh.

Leakage measured at test pressure less than 58 psig is adjusted to the equivalent value at 58 psig,

g. Deleted i

h. Drywell Surfaces The interior surfaces of the drywell and torus shall be visually inspected

,each operating cycle for evidence of j torus corrosion or leakage.
