, Safety Evaluation #90-547 Program Change to the Data Bank Dump Program e

Description ,

L' _

This_ change was due to a program error. . Exposure information was not F being~ automatically. transferred. The program was modified to make the correct.

h transfers every month.

g M Evaluation-

1. The' probability of an occurrence or the consequence of an accident, or malfunction of equipment important to safety as previously. evaluated-in the Final Safety Analysis Report is not increabed because the

' data generated by CMC will not be altered. It is currently supposed s to be transferred once per month. Correcting an error that is pre-venting' transfer will not affect safety as previously evaluated.

. 2. The possibility for an accident or malfunction of a different type than any previously evaluated in the Final Safety Analysis-Report is not created because the software. change has been tested,and controlled.

.No changes have been made that will affect accuracy of data transferred to NFS.

"E 3. lThemarginof. safety,asdefinedinthe.basisforanyTechnicalSpeci-s fication, is not reduced because this change has no effect on the operating thermal limits discussed in the Tech Specs.

L c 1. The. probability of an occurrence or the consequence of an accident,

The n,w fuel type (CE8x8NB) and analytical methods for establishing L the safety limit have received NRC approval..-Thus, this change did not increase the probability or consequences of.a previously l p evaluated accident in the Final Safety Analysis Report. ,

worst case would be the loss of theE1A-3201 feed. pump and the FSAk "I ~ ~

. evaluation is for the. loss of all three feed pumps. In addition,-

the feedwater system is not safety related. Finally, the unit operator
