REPORT 87-09 Reference:

Letter, G02-87-218, G.C.Sorensen (SS)to J.B.Nartin (NRC-RV), same subject, dated July 17, 1987 In the referenced

letter the Supply System committed to provide this supplemental

response to NRC Inspection

Report 50-397/87-09

regarding our plans to make post-trip review committees

more effective in the determination

of causative factors pertaining

to events.A detailed evaluation

of Plant Procedure 1.3.5,"Reactor Trip and Recovery", has been performed and, as a result, the procedure will be revised to include the following improvements:

1.The followup review committee will be assembled immediately

following any reactor trip unless otherwise directed by the Plant Nanager.2.When personnel performance

is a contributing

factor to an event, a peer review committee will be formed to evaluate the decision processes.

3.Predetermined

experts will be relied upon for cause investigation

in support of the restart decision process.It should be noted that this aspect is currently effectively.

performed and the change is to document who the resources are and facilitate

management

of the group.I 87Q910037f

Commission

Page Two September 1, 1987 NRC INSPECTION

REPORT 87-09 4.If the cause(s)of a reactor trip are indeterminate, a surveillance

method will be developed, if possible, to monitor the component/system

response following restart.5.Independent

verification

will be required of significant

conclusions

relied upon in the restart decision process and root cause assessment.

It is anticipated

that the procedure will be revised by November 30, 1987;however, in the interim, a management

letter has been issued which directs personnel to follow the intent of the changes.It should be noted that implementation

of these planned changes does not supplant the existing procedure.

Until such time that the procedure is revised, these changes are to be considered

as enhanced process policy, with Plant Management

as the primary implementor

of this policy.Should you have any questions regarding our response, please do not hesitate to contact me.Very truly yours, G.C.Sor nsen, Manager Regulatory
