1-was shutdown for re fue ling.

On December 14, 1985, at 2330 hours0.027 days <br />0.647 hours <br />0.00385 weeks <br />8.86565e-4 months <br />, the reactor was critical.

On December 16, 1985, at 1430 hours0.0166 days <br />0.397 hours <br />0.00236 weeks <br />5.44115e-4 months <br />, low power ph'ys ic s testing was c'omp le t e.

On December 17, 1985, at 1227 hours0.0142 days <br />0.341 hours <br />0.00203 weeks <br />4.668735e-4 months <br />, the generator was placed on line.

A pre s s ur i ze r s pr a y va lv e failed open causing a reduction in system pressure.-

Automatic Safety Injection resulted from low pre s s ur i ze r pressure.

Upon repressurization,~the RCS was taken s ol id resulting in a challenge to the pre s s ur i ze r power operated relie f ~ va lves at approximately 2335 psig.
