SUBJECT:

HOPE CREEK GENERATING STATION, REQUEST FOR ADDITIONAL INFORMATION REGARDING REQUEST FOR CHANGE TO TECHNICAL SPECIFICATIONS EMERGENCY DIESEL GENERATOR SURVEILLANCE TESTING REQUIREMENTS (TAC NO. MC1224)

Dear Mr. Anderson:

By letter dated October 23, 2003, PSEG Nuclear LLC submitted a license amendment request, LCR H03-07, for the Hope Creek Generating Station (Hope Creek) seeking approval of proposed changes to the Hope Creek Technical Specifications. Specifically, the requested change would delete surveillance requirements associated with the emergency diesel generator lockout features.

The Nuclear Regulatory Commission staff has been reviewing your submittal and has determined that additional information is required to complete our review. The required information was discussed with Mr. Courtney Smyth of your staff on April 8, 2004. Please provide your response to the enclosed question within 30 days of receipt of this letter. If circumstances result in the need to revise the target date, please contact me at (301) 415-1427.

Sincerely,

/RA/

REQUEST FOR ADDITIONAL INFORMATION REGARDING AMENDMENT REQUEST TO DELETE EMERGENCY DIESEL GENERATOR SURVEILLANCE REQUIREMENTS HOPE CREEK GENERATING STATION DOCKET NO. 50-354 By letter dated October 23, 2003, PSEG Nuclear LLC submitted a license amendment request, LCR H03-07, for the Hope Creek Generating Station (Hope Creek) seeking approval of proposed changes to the Hope Creek Technical Specifications (TSs). Specifically, the requested change would delete surveillance requirements (SRs) associated with the emergency diesel generator lockout features. The Nuclear Regulatory Commission staff has been reviewing your submittal and has determined that the following additional information is required to complete our review:

1. Title 10 of the Code of Federal Regulations (10 CFR), Section 50.36(b) requires that the TSs be derived from the analyses and evaluation included in the safety analysis report (SAR). Additional requirements for the contents of TSs are contained in 10 CFR 50.36(c)(2).

Hope Creeks Updated Final Safety Analysis Report (UFSAR) Section 8.3.1.1.3.3, "SDG

[Standby Diesel Generator] Tripping" indicates that when a Class 1E bus is energized only by the SDG (during loss of offsite power and/or loss-of-coolant-accident), each diesel engine and the circuit breaker that connects the diesel engine generator to the 4.16 KV Class 1E bus are tripped and locked out by protective devices under the following conditions:

1. Operation of SDG differential relay

2. Operation of the bus differential relay for the bus to which the SDG is connected

3. Engine overspeed

4. Low lube oil pressure

5. SDG overcurrent This section of the UFSAR indicates that these SDG lockout features were evaluated in the SAR to assure the availability of the SDG when needed pursuant with the requirements of general design criteria (GDC) 17. Pursuant with 10 CFR 50.36, the Hope Creek TS SR 4.8.1.1.2.h.14 requires verification that these trip and lockout features prevent diesel generator starting only when required. The proposed TS change deletes SR 4.8.1.1.2.h.14.

Provide a detailed explanation of how Hope Creek would continue to meet the requirements of GDC 17 and 10 CFR 50.36 following the proposed TS changes.
