REQUEST FOR ADDITIONAL INFORMATION RELATED TO GENERIC LETTER

96-05 PROGRAM AT HOPE CREEK GENERATING STATION (TAC NO. M97056)

Dear Mr. Keiser.

On September 18,1996, the NRC issued Generic Letter (GL) 96-05, " Periodic Verification of Design-Basis Capability of Safety-Related Motor-Operated Valves," to request that nuclear

, power plant licensees establish a program, or ensure the effectiveness of the current program, to verify on a periodic basis that safety-related motor-operated valves (MOVs) continue to be capabla of performing their safety functions within the current licensing basis of the facility.

On June 4,1998, Public Service Electric and Gas Company submitted an updated response to GL 96-05 indicating its intent to implement the provisions of a Joint Owners Group (JOG) ,

Program on MOV Periodic Verification at Hope Creek Generating Station (HCGS). The NRC staff has encouraged licensees to participate in the industry-wide JOG program to provide a j benefit in reactor safety by sharing expertise and information on MOV performance and to increase the efficiency of GL 96-05 activities at nuclear plants. Licensee participation in the JOG program also minimizes the amount of information necessary for the NRC staff to review I each licensee's response to GL 96-05. As a result, the NRC staff requires only limited additional

, information to complete its GL 96-05 review for HCGS. The specific information requested is addrecsed in the enclosure.

. REQUEST FOR ADDITIONAL INFORMATION FOR RESOLUTION OF GENERIC LETTER 06-05 ISSUES AT HOPE CREEK GENERATING STATION

1. In NRC inspection Report No. 50-354/96-04, the NRC staff closed its review of the i mVor-operated valve (MOV) program implemented at Hope Creek Generating Station (HCGS) by Public Service Electric and Gas Company (the licensee) in response to Generic Letter (GL) 89-10, " Safety < 'ted Motor-Operated Valve Testing and Surveillance." In the inspection reg::.., the NRC staff discussed certain aspects of the licensee's MOV program to be addressed over the long term. Fct example, the

inspectors noted that (1) eight gate valves were scheduled to be modified in RF07 to l increase their actuator capability; and (2) the licensee planned to use the Electric Power Research Institute MOV Performance Prediction Model where butterfly valve torque requirements were not clear or verified. The licensee should describe the actions taken to address the specific long-term aspects of the MOV program at HCGS noted in the NRC inspection report.

, 2. In a letter dated March 13,1997, the licensee stated its commitment to implement the 1 Joint Owners Group (JOG) Program on MOV Periodic Verification in response to l GL 96-05. The JOG program specifies that the methodology and discrimination criteria for ranking MOVs according to their safety significance are the responsibility of each participating licensee. In its letter dated March 13,1997, the licensee stated that the 4

frequency of static diagnostic testing at HCGS would be based on its Probabilistic Safety Assessment and an expert review. As HCGS is a boiling water reactor (BWR) nuclear

plant, is the licensee applying the Boiling Water Reactor Owners' Group (BWROG) methodology for ranking MOVs based on their safety significance as described in BWROG Topical Report NEDC-32264 and the NRC safety evaluation dated February 27,19967 If not, the licensee should describe the methodology used for risk ranking

. MOVs at HCGS in more detail, including a description of (1) the process used to develop l sample lists of highlisk MOVs from other BWRs; and (2) how expert panels were used to evaluate MOV risk significance.

3. The JOG program focuses on the potential age-related increase in the thrust or torque required to operate valves under their design-basis conditions. In the NRC safety avaluation dated October 30,1997, on the JOG program, the NRC staff specified that licensees are responsible for addressing the thrust or torque delivered by the MOV motor actuator and its potential degradation. The licensee should describe the plan at HCGS for ensuring adequate ac and de MOV motor actuator output capability, including

! consideration of recent guidance in Limitoroue Technical Update 98-01 and its Supplement 1.
