SUMMARY

OF OPERATING EXPERIENCE OPERATION:

The month began with the reactor critical and undergoing reload startup testing.

Zero power physics tests and turbine overspeed testing was completed by 1108 on January 2, 1979 and power escalation and at-power testing began. The power escalation rate was 37. p e t-hour due to limits of fuel pellet-clad interaction.

Full power was attained at 0100 on January 6, 1979 and testing was co:.qpleted.

A primary-to-secondary lead was detected on the "B" steam generator on January 5, 1979.

Leakage rate is 1 gpd.

This leak could be the same leak detected during Cycle I, and could have resulted from a leak in the plug inserted during Cycle I-II refueling. The reactor tripped on January 9, 1979 from a loss of EHC power while working on the turbine thrust bearing wear detector and recovery was delayed due to problems with defective fuses in the rod control system.

Full pcwer was again attained at 1615 on January 10, 1979 and was maintained for the rest of the month.

MAJOR SAFETY-RELATED MAINTENA' ICE:

Work continued on improvement modifications to the plant security system. The PDP charging pump valves and oil seal that had worn out were replaced. Work continued on the installation of an additional air compressor for plant instrument and service air requirements. An improved motor for the boric acid transfer pump was installed to enhance pump reliability. Work began on the replacement of the old (21" center) spent 'uel racks with new (13.3" center) spent fuel racks.

LICENSE CHANGES:

None MISCELLANEOUS:

The control room annunciating system-for the emergency diesel generators was altered at the request of the NRC to provide an additional alarm in the control room for diesel generator trouble.

A steam leak developed and was repaired on the "C" feedwater isolation valve.
