e I formed and it was discovered that 3 containment isolation valves were not f5T 11 closed. This represents a degraded mode of operation per Technical Specificat4 t o i s t I ion 6.9.1.12F. Since there was no occurrence which reauired containment iso- 1 lo is i i lation, this accident did not affect the health and safety of the public. Had t loirli there been an occurance reauirine isolation. the VA filters in the Auxiliary I iota 1i Building would have helped lessen any release.
