SHEARON HARRIS, UNIT 1

SUMMARY

OF MEETING WITHTHE CAROLINAPOWER AND LIGHT COMPANY (CP&L)

On March 3, 1998, the staff met with representatives of Carolina Power 8 Light Company (CP8L) to discuss the Shearon Harris Nuclear Power Plant (SHNPP) 'C'nd 'D'pent fuel pools activation project.

Enclosure 1 is a list of meeting attendees. is a copy of the handout provided at the meeting. The CP8L presentation included background information, a discussion of licensing activities, and the project schedule.

~a:kiikgund Originally, SHNPP was intended to be a four unit site with four fuel pools (A,B,C, and D) and two Fuel Pool Cooling and Cleanup systems (FPCCS). Although three of the four units were canceled, the construction of all four pools and one of the FPCCS was completed.

Also, a portion of the piping for the other FPCCS was installed. Currently pools 'A'nd 'B're in service and not only store SHNPP fuel, but also store spent fuel from other CP8L plants (Brunswick Units 1& 2, and Robinson).

Pools 'C'nd 'D're not in service.

CP8L has determined that pools 'C'nd 'D'illbe needed to ensure all four units maintain a prudent operating reserve for core off loads. According to CP8L, pool 'C's needed by early 2000 to support fuel shipments from Brunswick and Robinson.

In order to place pools 'C'nd

'D'n service, the FPCCS and pool racking must be completed for pools 'C'nd 'D'.

IC I

The second licensing activity discussed involved piping certification for the 'C'nd 'D'PCCS.

A portion of the piping for the 'C'nd 'D'PCCS is already installed, with some embedded in concrete, making approximately 14 field welds inaccessible.

CP8L inadvertently disposed of the piping certification records for the installed piping, which makes it unable to demonstrate that the piping satisfies the design requirements of American Society of Mechanical Engineers (ASME) Code Section III. CP&L stated that it intends t Section III. The staff stated that a relief request from o request relief from ASME Code the requirements of ASME Code IIIMRE CEImy~ ~y 9803200255 9803ii PDR ADQCK 05000400 PDR CP8L identified three licensing activities associated with the completion of pools 'C'nd 'D'.

The first is a potential unreviewed safety question (USQ) associated with the modification of the Unit 1 Component Cooling Water (CCW) System.

Although the Unit 1 CCW system was not originally designed to cool the FPCCS for pools 'C'nd 'D', CP&L has determined that the Unit 1 CCW system has sufficient margin to accept the 'C'nd 'D'PCCS load. The original design was for the Unit 1 CCW to cool the FPCCS for pools 'A'nd 'B', and for the Unit 2 CCW system to cool the FPCCS for pools 'C'nd 'D'. The staff asked several questions about the spent fuel pool, the FPCCS, and CCW system designs.

The staff also inquired about SHNPP fuel handling practices.

0 Pi Section III would not be appropriate.

The staff recommended that CP8L propose an alternative method, as allowed by 10 CFR 50.55a, that provides an acceptable level of safety and quality.

CP8L agreed with the staff's comments and stated that a relief request was not the appropriate terminology for its request.

CP8L stated that it intends to propose a piping certification plan, which includes tests and inspections, as an alternative method to the requirements of ASME Code Section III.

CP8L also intends to submit a Technical Specification (TS) change for high density racks in pools 'C'nd 'D'. The TS change would modify SHNPP spent fuel capacity.

~Sh.dt.ILe I

CP8L stated that the TS change and the piping certification plan will be ready for submittal this summer, and the CCW USQ will be ready by fall. Due to the complex nature of this review, the staff recommended that CP8L make one complete submittal that includes all three licensing activities as oppose to three separate submittals.

The staff also recommended that CP8L may want to meet with the staff again in the summer to discuss, in more detail, the TS change and the piping certification plan.

CP8L agreed with the staffs recommendations, and intends to submit 'one amendment encompassing all three licensing activities in the fall. CP8L stated that approval is needed by the end of 1999.

Background/History A

o Original HNP Design

+ Four (4) nuclear units; four (4) fuel pools; two (2) cooling systems e Units 2, 3 and 4 canceled in early 1980's,

+ Allfour pools completed

+ Pools 'A'nd 'B'laced in service to support HNP Unit 1 and spent fuel shipping fiom BNP and RNP

+ Cooling system for pools 'C'nd 'D'as not completed

+ Plan at time of Unit 1 license was to corn lete cooling s stem and place pools 'C'nd '

in service w en necessary

Backgm oundlHistory Continued f

T A

o Some installation documentation not available

+ System cannot be certified to ASME Section III without all documentation o Fuel Pool 'C's needed in early 2000 to support spent fuel shipping requirements from BNP and RNP

e. Without pool 'C' All 4 units lose prudent operating reserve by Spring 2000

+ HNP loses full core reserve in fall 2001

+ HNP forced shutdown in 2006

BackgroundlHistory Continued o Pools 'C'nd '0'using optimized rack designs} are needed to provide spent fuel storage capacity for all four units through end of licensed life

+ BNP and RNP pools willbe full when licenses expire

+ Additional storage capacit (such as dry storage facilities) willbe needed if ife extension is pursued at any of the units
