, at irma The Reactor Power Level averaged 100% until the Unit was shutdown on 12/2 for repair of a tube leak on the "B" Steam Genexator.
The pressurizer relief line nozzle was also repaired during the shutdown.
On 12/17 the Reactor was taken critical and shortly afterwards was placed in the hot shutdown condition when the Boric Acid Tanks were found.to be out of specifications due to low boron concentration.
The Unit remained shut-down until startup on 12/19.
The Reactor Power Level was gradually increased to 100% on 12/20 and remained there for the remainder of the Report Period.

r GINNA STATION MAIN ANCE REPORT FOR DECEiSER 1979 During December, normal inspections and minor maintenance was performed.
Major safety related maintenance included:
1.
Replacement of one source range (NV-32) and both intermediate ranges (N-35, N-36) of the nuclear instrumentation.
2.
Plugging of two leaking tubes and 11 other tubes that were within the plugging criteria in the "B" steam generator.
3.
Permanent repair of the south handhole on the "B" steam generator by welding the damaged area on the steam generator flanged area.
This had previously been repaired using furmanite.
4.
Replacing the body to bonnet gasket on pressurizer spray valve 431A.
5.
Replacement of a spare primary loop RTD.
6.
Weld repair of the corrosion cracking on the pressurizer relief valves safe'nd.
.7.
Replacement of reactor protection relay RT 10 on train "A" after a failed coil was found.
