. considered significant NRC' concerns.

Four of these unresolved items involve.

l

'the series of incidents"which' occurred between October 10-15,.1987, during

~ second refueling outage. The remaining two unresolved items involve the

-

operability of the Contro1~ Room Ventilation Isolation $ystem and the setpoints

of the pressurizer power operated relief valves. .The problems involving the

setpoints of the pressurizer relief valves has been a continuing problem at

WCGS.. This issue, as well_as all of these matters require prompt attention as

'NRC inspction efforts. Some of these matters, including four additional
