Dear Mr. Vassallo:
SUMMARY
A telephone conference call was held on February 2, 1982, between NRC and Carolina Power & Light Company (CP&L).
Participants are listed on.
This conversation was in regard to CP&L's plans to establish reload design capability for the Brunswick Steam Electric Plant, Unit Nos. 1 and 2.
The purpose of the call was to discuss scheduling and to obtain NRC Staff guidance regarding the content of submittals.
Tentative plans for a follow-up meeting were also discussed.
DISCUSSION The following items were discussed during the conversation:
1.
An update and refinement of the schedule given in our September 8, 1981, letter was presented by CP&L.
The attached figure (Enclosure 2) presents the schedule resulting from the ensuing discussions and current outage plans.
Basically, CP&L plans to submit BWR steady-state neutronic and thermal hydraulic topicals in the fourth quarter of 1982, followed by submittal of transient analysis topical reports in late 1984. Plana for a process computer methodology topical have been suspended until such time as a firm determination can be made of the direction to be taken by the fuel vendor.
2.
NRC indicated that CP&L's desire to begin using the steady-state methodology in August 1983 represents a very tight review schedule based on a submittal in late 1982.
NRC suggested that we submit drafts of our topicals as early as possible in 1982 so they can determine if all important points are addressed and to help them establish the amount of time needed to conduct the review in fiscal 1983.
Additionally, NRC suggested that CP&L meet with them periodically to provide a continuing dialogue regarding the scope of 411 Fayetteville Street

the submittals, additional information-that may be necessary. CP&L's capabilities, etc.
CP&L agrees that this would be mutually beneficial.
We will submit draft topicals as soon as possible, and we plan to meet with NRC in March to present an overview of the activities we have been conducting and to review the benchmarking we have finished to date.
The meeting date will be _ set up through the Project Manager.
At this time, we'see the need for an additional meeting on the RECORD and PRESTO-B codes. Enclosure 2 presents a tentative date in April.
This meeting date will also be' set up through the Project Manager.
3.
A discussion was held regarding the Scandpower codes, RECORD (the lattice physics code) and PREST 0-B (the BWR nodal simulator), which form the basis of the methodology developed by CP&L.
NRC wants to be able to review these codes, and we discussed whether to submit them generically or on the Brunswick docket.
Based on this conversation, CP&L prefers to submit the RECORD and PREST 0-B topical reports on the Brunswick docket along with the methodology / benchmark topicals CP&L is preparing.
This does not preclude an independent submittal of the RECORD and PREST 0-B codes by Scandpower for generic review.
Therefore, CP&L's final submittal of steady-state topical reports in 1982 would involve four documents:
- RECORD:
This document will contain a detailed description of the lattice physics code developed by Scandpower, along with appropriate benchmarking.
- PRESTO-B: The contents of this document will describe the BWR nodal simulator developed by Scandpower and the benchmarking of the code.
- BWR Neutronics Methodology:
This document will describe the metbodology developed by CP&L for the use of the PRESTO-B and RECORD codes on the Brunswick 1 and Brunswick 2 cores.
Detailed benchmarking against Brunswick Plant measurements (all cycles to date) will also be included.
- FIBWR:
A brief description of the FIBWR code, developed by EPRI, will be presented along with the application proposed by CP&L and detailed benchmarking against the Brunswick Plant measurements.
4.
NRC initiated a discussion on CP&L's plans for submitting a fuel pin temperature calculation model.
The consensus reached was that submitting euch a topical was not necessary for the steady-state
