• OCT 111995 LR-N95179 PSE&G Commitments The following commitments have been made by PSE&G as a result of the investigation into LER 272/95-024:

Near Term Actions

• A surveillance test will be performed using the revised methodology prior to declaring the system operable.

• Direction will be provided to appropriate personnel regarding the impact of manipulating non-safety Fuel Handling Ventilation (FHV) components on the operability of the FHV system.

• The FHV dp alarm setpoints will be reset to -0.13" wg until such time that the design basis setpoint is validated by Engineering.

Long Term Corrective Actions

1. The design basis and setpoints for the FHV system pressure controller, differential pressure switch (alarm), and radiation monitors will be established.

This activity is expected to be completed by December 11, 1995.

2. . Disposition all open issues identified in Discrepancy Evaluation Forms (DEFs) which affect the operability of the FHV system prior to restart, which is expected during the first and 3econd quarter of 1996 for Units 1 and 2, respectively.

3. Identify inconsistencies between the established design, technicaL specifications and surveillance test procedures prior to restart, which is expected during the first and second quarter of 1996 for Units 1 and 2, respectively.

4. The impact of the Technical Specification changes and clarifications developed on the design, testing, and maintenance of the FHV system will be formally communicated to appropriate personnel . This training will be provided to appropriate personnel prior to restart, which is expected during the first and second quarter of 1996 for Units 1 and 2, respectively ..

5. A condition resolution has been initiated to address the failure to detect the miswired alarm.

6. Evaluate and identify, where required, the need for controls to prevent unauthorized manipulation of HVAC components (e.g., dampers, vents, controllers, alarms, etc) which can affect TS compliance/operability of a safety related system. *

7. Operator response to the FHB dp alarm condition, involvement in approval of the work order which allowed manipulation of the non-safety damper, and adequacy of the alarm response procedure will be further investigated.

8. Action has been initiated to evaluate the aggregate impact of the HVAC deficiencies, as discussed in "Prior Similar Occurrences" . A cumulative impact evaluation will be performed to identify any additional corrective actions required other than those considered in the corrective actions listed in the individual LERs.
