Subject:
Correction of Units in Previous Submittal on the Quad Cities Nuclear Power Station Unit 1 Cycle 13 BLTA Program NRQ DockeLNo 50 254
Reference:
J. L. Schrage (CECO) letter to T. E. Murley dated July 23,1992 The reference submittal described Commonwealth Edison's (CECO) plans for continued use of six fuel rods from the Barrier Lead Test Assembly (BLTA) at Quad Cities Station Unit I during Cycle 13.
A minor discrepancy was identified in the exposure units used in the second page e bumup was stated as 64.4 of the Peterence letter. The pro ected lead rod averag'To maintain consistency, the GWd per Short Ton (ST) insteac of Metric Ton (MT).
subsequent sentence also requires a correction. The revised sentences are shown below.
The highest best estimate rod average exposure for the six BLTA rods at end End-of-Cycle 13 is 64.4 GWd/MT. General Electric's approved Topical Report NEDE 22148 P-A,"Exterided Burnup Evaluation Methodology," dated November 1985, states that the General Electric methods are valid for rod average exposures of at least 60.0 GWd/MT.
The corrections have no impact on the planned BLTA program and merely restore consistency with the correct values from the GE Safety Evaluation, which was enclosed in the Reference submitial. This minor correction has been discussed with both L. N.
Olshan (NRR Project Manager) and L. E. Phillips in the Reactor Systems Branch.
