SUMMARY
OF OPERATING EXPERIENCES At the beginning of the month, the plant was in hot shutdown while a gnnerator hydrogen leak was being repaired.
Cn March lith, the reactor was made critical, the unit was phased to the grid, and loading commenced.
On March 12th, 30% power was maintained for a boron soak.
On March 13th, loading commenced.
On March 14th, 98.8% power was reached and maintained while the feed flow calorimetric was eval uated.
A limit of 882 MWe was maintained pending generator capability evaluation.
On March 17th, 98.8% power (882 MWe) was maintained while the generator hydrogen gland seal ring rub test and vibrations in the exciter and gunerator were evaluated.
For the remainder of the month, a limit of 802 MWe was maintained due to generator vibration concerns.
