Licensee Action on Previous Inspection Findings (Closed) Inspector Follow Item (50-213/80-CI-21); " Regulation of Refueling Crews". Review of FP-CYW-R1D, " Refueling Procedures for Cycle X-XI, Connecticut Yankee", fadicated that the requirements of IEC 80-21 were being satisfied. This item is closed.
<
(Closed) Unresolved Item (50-213/80-24-02) " Control Rod. Drop Times". The hot rod drop time tests were conducted with three reactor coclant pumps operating instead of four pumps. The licensee used a 0.05 second correction to account for three pump operation. The correction was derived from earlier test results which were not available for review during the previous inspection.
The inspector reviewed these test results; the use of the 0.05 second correction was justified.
The inspector had no further questions regarding this item.
(Closed) Noncompliance (50-213/80-24-01) " Failure to Review and Approve Startup Test Procedure SUR 5.3-6, Computational Errors therein and in calculation of Moderator Temperature Coefficient." The licensee representative has reviewed and corrected the test results.
In addition, Revision 5 to SUR 5.3-6 has since been issued which provides detailed instructions on how tu calculate the Moderator Temperature Coefficient.

Maintenance Witnessed The inspector witnessed the performance of maintenance on Emergency
^
Diesel Generator (EDG) 2A. The work was being performed in accordance with procedure PM 9.5-36 which included:
--
administrative approvals for removing the system from service and returning it to service;
--
appropriate hold points for inspection, audit and signoff by QA or other licensee personnel; provisions for operational readiness inspections following
--
maintenance; provisions for assuring that LCO requirements of the technical
--
specifications were satisfied during the repair period;

The inspector verified that the reactor operators were aware that EDG l
2A was tagged out of service, that the tools and gauges being used by the technicians had current calibration certifications, that the work'
was being performed by experienced and knowledgeable technicians, that the required tagouts had been performed in accordance Nith the procedure, and that all prerequisites in the procedure had been signed off.
In addition the inspector reviewed the completed, signed procedure (PM 9.5-36) and work permit (W.P. No. MA 2633) for EDG 28.~The. preventive maintenance on this generator had been completed the previous week.
All appropriate verifications had been signed off.
In addition the inspector toured the EDG 2B room and verified that tagouts had been removed and the work area had been carefully cleaned. The reactor operator reported that EDG 2B had been tested and verified to be operational.
