<d weric' Letter' 87-12' (Reference a), we pro <,ided a description of in our response to (i} operation Calvert Cliffs' plant during the approach s.to, and viith, a partially filled Reactor Coolant' %ystem (RCS). In addition, we statev lthat ' we 'were' working with the j
Combustion' Engineering Owners Group to review-one concern prevented in the Generic Letter, Specifically, the concern is a loss of res? dual heat remov;at (RiiR), leading to i
.RCS pressurization and pokniial eNetiou^,0f coolant via a cold leg opening (e.g.,
maintenance on iNReactor Coolant Pump seal assembly).
We will not receive Cortbustion E93ineering's final report, which qualitatively assesses this scenario, any earlieg than the end of October. As discussed in Reference (b), we expect to, pro 4ide our gesponse to t)id concern by November 16, 1987 This will allow approximately two weeks for rehw of the final report.
