On May 3, 2000, a Notice of Violation was issued for two Severity Level III violations and one Severity Level III problem. This first Severity Level III violation was based on the failure to correct a condition adverse to quality involving the service water and river water pump vacuum break check valves that rendered a SW pump inoperable. The second Severity Level III violation involved the failure to perform an adequate design review of a temporary modification to the filtered water system (a source of seal water to the RW pumps). The Severity Level III problem was based on design deficiencies associated with the seal water supply to the RW pumps, and the failure of the RW pump testing program to identify one of those deficiencies.
