the following violation was identified.
Technical Specification 3.6.1.1 requires th'at containment integrity shall be maintained in modes 1, 2, 3, and 4 and that containment penetration
, isolation be verified periodically.

Valve 1-33-704 was normally maintained in the open pusition however, the outside containment isol.ation valve, 1-33-740, was maintained closed and periodically ve'rified to be in the proper position during unit operation.
This is a Severity Level IV Violation (Supplement I.D.3.).
