Statement of Work TASK ORDER 244, TITLE: Technical Assistance in Evaluating a Proposed increase in the Allowed Ultimate Heat Sink Temperature H. B. Robinson, Unit 2 NRC PROJECT MANAGER: Lawrence Ruth, NRR/DSSA (301) 415-1211 E-Mail: Icr@nrc. gov NRC TECHNICAL MONITOR: James Tatum, NRR/DSSA/SPLB (301) 415-2805 E-Mail: jet 1@nrc. gov TAC NUMBER: MA5612

- PERIOD OF PERFORMANCE: .Date of Award through November 30,1999 BACKGROUND The ultimate heat sink (UHS) for H. B. Robinson (HBR), Unit 2, is Lake Robinson. During plant operation, the Technical Specifications for HBR require that the lake level be 2218 feet mean

- sea level, and that the lake temperature be s95 *F, in order to assure sufficient cooling capability during postulated plant accident conditions. However,' periodically during hot summer months, the lake temperature can exceed 95 *F for short periods of time. In order to better accommodate continued operation of the plant during the summer, Carolina Power and Ught Company (CP&L, or the licensee), has proposed a change to the Technical Specification requirements to increase the maximum alicwed UHS temperature to 97 *F.

OBJECTIVE The objechve of this task order is to obtain the necessary technical expertise to review the licensee's evaluation supporting the proposed increase in the maximum allowed UHS temperature for HBR in an expedited manner, and to independently assess whether the increase in UHS temperature will have any adverse effects.

TECHNICAL AND OTHER SPECIAL QUALIFICATIONS REQUIRED The contractor must have in<iepth knowledge of pond or reservoir-type UHS design and operating requirements for commercial nuclear power plants, and have considerable knowledge and experience in performing heat transfer analyses associated with the UHS, power plant fluid systems, and related components and structures. The contractor must have considerable knowledge and experience in determining the maximum allowed fluid system temperature that can be tolerated for operation of power plant fluid systems, components, and structures, including the ability to assess the effects of increased fluid temperature on containment performance.. The contractor must be familiar with NRC licensing criteria and typical plant design basis requirements.- The contractor is preferably someone who has a Ph.D. and is an expert in heat transfer analysis (or related field), and is familiar with standard Westinghouse computer codes for assessing containment performance.

WORK REQUIREMENTS AND SCHEDULE TASK COMPLETION SCHEDULE

1. Review the CP&L submittal dated March 26,1999, August 27,1999 review calculations that have been completed in support of the March 26 submittal, focusing primarily on methodology and assumptions, and determine whether additional information or analysis by the licensee is required in order to justify the proposed )

increase in UHS temperature. Through this review, confirm that the licensee used worst-case conditions and single failure assumptions as appropriate, and idegtify any significant changes in design-basis assumptions that are less conservative for staff review and consideration. Much of this work will be completed at the site (or other location as designated by CP&L) in order to facilitate access to the licensee's calculations and design information.

2. If additional information is required, prepare a request September 3,1999 for additional information (RAI), and provide it to the Technical Monitor. Both hard copy and electronic version are required.

3. Review the licensee's RAI response (if applicable), Wdhin one week after and perform independent analysis (as necessary) in receiving the licensee's RAI order to identify any significant problems that may response, or by September exist related to the proposed relaxation of UHS 17,1999 (if an RAI was not temperature requirements, required).

4. The contractor shall prepare a written Technical Within two weeks of Evaluation Report (TER) documenting the results of . completing Task 3.

his/her evaluation, noting any significant non conservative changes in design-basis assumptions or unresolved problems that were encountered during -

the review. Sufficient information must be included in the TER to allow the Technical Monitor and CP&L to understand what was done during the review, and the basis for the conclusions that were reached.

5. If requested by the NRC staff, the contractor shall To be determined based on attend a meeting in Rockville, MD, to discuss the contractor's availability.

information contained in the TER and to answer any questions that the NRC staff or CP&L may have.
