RESPONSE
The foregoing statement is correct, however, this incident is not indicative of a lack of adequate response to alarms as a generic issue at Oyster Creek.
Management efforts have been ongoing in the Oyster Creek Operation Department to address this ccncern relating to alarm response and follow-up. As stated in the inspection report, a memo was issued to all operations personnel stressing alarm follow-up and correction.
While the memo and past actions have not been totally effective in resolving this issue, Oyster Creek Management believes considerable improvement has been realized. The non-compliance in this particular case resulted mainly from not adequately communicating a known condition and, allowing a known discrepancy to exist.
Management has been personally stressing to shift personnel the need to follow alarming conditions to proper disposition. This attention has been directed in the form of memos, procedural requirements, policy statements, and direct verbal communication with the operators
?
Mr. Grier-April 21, 1981 and shift supervision on the status of existing alarm conditions.
This has been a topic of discussion at times with the resident inspector and he has acknowledged management efforts and results in this area of alarms and alarm response.
In this particular incident, as stated in the inspection report, an Engineering Request had beea initiated to evaluate the alarm set point prior to the non-compliance.
The condition, however, was allowed to recur and was not addressed with regard to correcting on an interim basis until a final resolution was determined and implemented. Additionally, the information on the condition and status of the corrective action was not adequately communicated to operations personnel.
CORRECTIVE STEPS WHICH HAVE BEEN TArfN Since the identification of the non-compliance, the alarm set point of the Filter High Pressure Differential has been reset to a value to clear the alarm and still allow for indication of problems with the filter.
The condition at no time affected the operability of the system since the acceptance criteria for the parameters of concern were well within limits. As a further measure of recognition of the problem, memos addressing this condition and the overall operating policy and practice related to management controls have been sent to licensed shift operators.
CORRECTIVE STEPS WHICH WILL BE TAKEN TO AVOID FURTHER ITEMS OF NON-COMPLIANCE It is planned to meet with all licensed shift operators to discuss Administrative Controls related to shift operation and, in this session, the subject of alarms and alarm response will be addressed.
This is an area that will continue to be addressed by Oyster Creek Management both in operator action in response to alarms and in the maintenance of equipment / instrumentation to correct repeated alarming conditions. Based on the above it is felt Oyster Creek Mancgement is being responsive to your stated concerns on this recurrent item.
DATE OF FULL COMPLIANCE Full compliance is being achieved with regard to operator instructions and action on alarming conditions in the plant.
