ATTACHMENT Response to Item of Noncompliance Inspection Report Nos.
50-373/83-12 ano 50-374/83-10 Item of Noncompliance Technical Specification 6.2 requires that detailed written procedures shall be written, approved and adhered to for emergency conditions involving potential or actual release of radioactivity and references both-the " Generating Station Emergency Plan" and station emergency and abnormal procedures.
LaSalle Emergency Procedure LZP 1310-1, " Notifications", specifies the communications-requirements for an Unusual Event and Table LA 5-1 of the Generating Station Emergency Plan requires that an Unusual Event be declared-in the event of a non-spurious ECCS initiation.
Contary to the above requirements, on March 22, 1983, following a react'or
-scram, the High Core Spray System automatically initiated and an Unusual Event was not declared nor were the notifications required by LZP 1310-1 made.
}
' Response Corrective Action Taken and Results Achieved The required ENS phone notification was made within one hour of the event identifying the Reactor Protection System actuation (reactor scram)'and High Pressure Core Spray (HPCS) initiation Additionally, the. Unit Operating Engineer and Assistant Superintendent Operations were notified of the event within a short time.
While the HPCS did auto ~ initiate (not spurious) and assist in returning reactor water level to normal; the event was not considered as a loss of Primary
- Coolant as identified in Generating Station Emergency Plan (GSEP) l implementing procedures and thus the Unusual Event classification was not identified.
Ai the time of the notification, the primary concern was, in fact, high reactor water level.

, Corrective Action Taken To Avoid Further Noncompliance The station personnel involved in the event have been briefed-as to the proper classification and parameters which must be considered when evaluating GSEP classification.
Additionally, the reporting requirements of this event will be presented to the licensed shift supervisors.
Date When Full Compliance Will Be Achieved Full compliance has been achieved at this time.
