SUBJECT:

REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE CRYSTAL RIVER UNIT 3 NUCLEAR GENERATING PLANT, LICENSE RENEWAL APPLICATION (TAC NO. ME0274)

Dear Mr. Franke:

By letter dated December 16, 2009, Florida Power Corporation submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54, to renew the operating license for Crystal River Unit 3 Nuclear Generating Plant, for review by the U.S. Nuclear Regulatory Commission (NRC or the staff). The staff is reviewing the information contained in the license renewal application and has identified, in the enclosure, areas where additional information is needed to complete the review. Further requests for additional information may be issued in the future.

Items in the enclosure were discussed with Mr. Michael Heath, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-3733 or bye-mail at Robert.Kuntz@nrc.gov.

Sincerely, Robert F. Kuntz,

. Project Manager Projects Branch Division of License Renewal Office of Nuclear Reactor Regulation Docket No. 50-302

REQUEST FOR ADDITIONAL INFORMATION LICENSE RENEWAL APPLICATION FOR CRYSTAL RIVER UNIT 3 NUCLEAR GENERATING PLANT DOCKET NO. 50-302 Request for Additional Information (RAI) 3.3.2.2.4-1

Background

Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants (SRP-LR) Section 3.3.2.2.4, "Cracking due to Stress Corrosion Cracking and Cyclic Loading,"

recommends further evaluation of stainless steel non-regenerative heat exchanger components exposed to treated borated hot water in the chemical and volume control system. The SRP-LR states that the effectiveness of the water chemistry control program should be verified to ensure cracking is not occurring. The SRP-LR also states that an acceptable verification program includes temperature and radioactivity monitoring of the shell side water, and eddy current testing of the tubes.

License renewal application (LRA) Section 3.3.2.2.4.1, stated that the Water Chemistry and One-Time Inspection programs will be used to manage cracking of the make-up and purification system letdown heat exchanger components. The LRA also stated that the One-Time Inspection Program was selected in lieu of radioactivity monitoring of the shell side water and eddy current testing of tubes.

It was unclear to the staff what inspections were being proposed in the One-Time Inspection Program in lieu of temperature and radioactivity monitoring of the shell side water and eddy current testing of the non-regenerative heat exchanger tubes. The proposed inspection could be eddy current testing of alternate component(s) in lieu of the non-regenerative heat exchanger tubes, or an alternate nondestructive examination method of the non-regenerative heat exchanger tubes or something else.

Request Clarify what inspection activities are being proposed in the One-Time Inspection Program in lieu of temperature and radioactivity monitoring of shell side water and eddy current of the non-regenerative heat exchanger tubes.

If an alternate nondestructive examination method is being proposed in lieu of eddy-current testing of the non-regenerative heat exchanger tubes, provide plant-specific or industry operating experience to demonstrate the effectiveness of the proposed methodology.
