LER CONTINUATION - R04 1-79-062 Facility:

BSEP Unit No. 1 Evenc Date:

08-28-79 CAUSE DESCRIPTION AND CORRECTIVE ACTIONS:

Conservative operating limits for bundle LJO 197, based on analyzed values given the BSEP Unit No. I supplemental reload licensing packagt submitted for cycle 2 (NEDO 24166), were determined and power was reduced to approximately 88% in order to e serve these limits. Tha daily core parameter limits was re-vised to include these special limits for bundle LJG 197.

It was verified that no other bundle was rotated in either Unit 1 or Unit 2.

Anslyses to determine the feasibility and desirability of continued operation were initiated by both CP&L and G.E. and the results of these analyses will be provided in a supple-mental report.

It was verified that the fuel loading error is analyzed for in the current cycle and results in no safety Ibnit violations. It was also verified that no transients upsets which have occurred this cycle could have caused a safety ifmit violation. It is General Electric's opinion that the single misoriented bundle does not compromise the current license basis.

The core verification proccdure will be revised to include:

1)

Initials for each bundle orientation requiring that at least 2 of 5 methods of verification be used, and those methcds used, identified.

2) Complete core verification of core loading and orientation, from the core load videotapes, by an independent verification team consisting of at least two of the following personnel:

a) Operating Supervisor b) Q A. Supervisor c) Engineering Supervisor d) Representative from CP&L Nuclear Fuels e) Reactor Project Engineer f) Other technically qualified personnel

3) Fuel movement sheets will be revised to add columns for channel fast-ener orientatien so that the refueling floor SRO can determine bundle orientati2n both before and after a move.
