NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE APRIL 1982 i'

At the onset - of April 1982 reporting period, the reactor was at 28%

Rated Thermal Power (8 MWe-Net).

A gradual escalation to 80% Rated Thermal Power (37 MWe-Net) was in progress due to an automatic shutdown in the preceding report period.

On April 8, -1982 at 2300, a de-escalation commenced for the scheduled refueling outage.

The turbine was manually tripped at 0550 4

on April 9,

1982 and the reactor was manually shut down immediately thereafter.

Significant maintenance iteiits performed during the reporting period a re indicated or the attached Mechanical Maintenance and Instrument and Electrical Maintenance listings.
