ATTACHMENT 1 10 CFR 2.201 INFORMATION PUBLIC SERVICE ELECTRIC AND GAS COMPANY HOPE CREEK GENERATING STATION RESPONSE TO NOTICE OF VIOLATION INSPECTION REPORT NUMBER 50-354/87-08 Your letter dated May 1, 1987 identified a violation wherein, contrary to the requirements of Technical Specifications 2.2.1 and 3.3.1, the station was operated, between November 1986 and April 13, 1987, at full power for extended periods of time with the main steam line radiation high-high trip setpoints less conservative than 3.6 times full power background.
Technical Specification 2.2.1 requires that the main steam line radiation high-high trip setpoint be established at a value less than or equal to 3.0 times full power background and, that with a setpoint less conservative than 3.6 times the full power background radiation levels, the affected channel shall be declared inoperable.
Technical Specification 3.3.1 requires that, with less than 2 operable main steam line radiation channels per reactor trip system, at least one trip system shall be placed in the tripped condition and the plant shall be placed in STARTUP, with the mainsteam isolation valves closed, within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> or in at least HOT SHUTDOWN in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

PUBLIC SERVICE ELECTRIC AND GAS COMPANY DOES NOT DISPUTE THE VIOLATION.
2.
THE ROOT CAUSE OF THE VIOLATION WAS PERSONNEL ERROR IN THAT:
In December, 1986, the results of full power baseline Main Steam Line (MSL) radiation data obtained during startup testing, were used in the preparation of a Design Change Request (DCR) which would have changed the subject trip setpoints to comply with the requirements of 3 times full power background radiation.
However, a System Engineering Management review failed to properly prioritize the DCR so that it could be completed in a timely manner.
Consequently, the DCR was still awaiting implementation when the violation of technical specifications was discovered.
Station personnel believed that the MSL high-high radiation setpoints, during the November 1986 through April 13, 1987 period, were within the 3 times background Technical Specification requirement when, in fact, the setpoints were slightly higher than the required limits.
ATTACHMENT 1 3.
IMMEDIATE CORRECTIVE ACTIONS Upon determination that the MSL radiation monitor trip setpoints were non-conservative, Action Statement 5 of Technical Specification 3.3.1 was entered at 1320 on April 13, 1987, which mandated being in HOT SHUTDOWN within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
The trip and alarm setpoint values for all MSL radiation monitor channels were recalculated and adjusted downward based on the previous 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />' MSL background radiation levels. The channels were declared operable and the Action Statement was cleared at 1430 on April 13, 1987.
The station System Engineering Department stressed, at staff meetings, the need for emphasis on Technical Specifications requirements during the initiation of Design Changes.
4.
CORRECTIVE ACTIONS IN PROGRESS MSL radiation levels are being trended and compared to the trip setpoints on a routine basis to ensure that the permanent setpoints are maintained equal to or less than 3 times full power background.
All permanent System Engineers are currently undergoing licensing training.
This training includes detailed review of Technical Specifications and their applications to plant equipment.
5.
FULL COMPLIANCE WAS ACHIEVED ON APRIL 13, 1987..,. -
