February 13, 2008 Mr. Dennis R. Madison Vice President - Hatch Edwin I. Hatch Nuclear Plant 11028 Hatch Parkway North Baxley, GA 31513
SUBJECT:
EDWIN I. HATCH NUCLEAR PLANT, UNIT NOS. 1 AND 2 (HNP), REQUEST FOR ADDITIONAL INFORMATION (RAI) REGARDING ALTERNATE SOURCE TERM APPLICATION (TAC NOS. MD2934 AND MD2935)
Dear Mr. Madison:
By letter to the Nuclear Regulatory Commission dated August 29, 2006, Southern Nuclear Operating Company, Inc., proposed to revise the HNP licensing and design basis with a full scope implementation of an alternative source term. We have reviewed your application and have identified a need for additional information on electrical power issues as set forth in the Enclosure.
We discussed this issue with your staff on January 15 and February 1, 2008. Please provide a response within thirty (30) days of receipt of this letter.
Sincerely,
/RA/
Robert E. Martin, Senior Project Manager Plant Licensing Branch II-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-321 and 50-366

ENCLOSURE REQUEST FOR ADDITIONAL INFORMATION CONCERNING IMPLEMENTATION OF AN ALTERNATIVE SOURCE TERM APPLICATION FOR EDWIN I. HATCH NUCLEAR PLANT, UNIT NOS. 1 AND 2 (HNP)
- 1.
Provide assurance that the emergency diesel generators are capable of supporting the electrical load being added as a result of supplying the turbine building exhaust fans from a Class 1E power source. Include a detailed summary of any analyses used to make this determination.
- 2.
Discuss how the reliability and availability of the turbine building exhaust fans and the associated electrical circuits, including individual fans and transfer switches, will be monitored and maintained.
- 3.
Describe how electrical isolation will be maintained between non-Class 1E and Class 1E circuits. If double isolation (e.g., two breakers in series, a breaker and a fuse, or a breaker supplied with a loss-of-offsite power signal) is not used, provide a detailed discussion on how a fault on the non-Class 1E electrical circuit will not propagate to the Class 1E electrical circuit.
