SUMMARY
OF OPERATING EXPERIENCES a
1 At the beginning of the month, the plant was.in hot shutdown while a generator hydrogen leak was being repaired.
On 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 baron soak.
On March 13th, loading commenced.
On March 14th, 98.8% power was reached and maintained while the feed flow i
calorimetric was evaluated.
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
]
generator were evaluated.
For the remainder of the month, a limit of 882 MWe was maintained due to generator vibration concerns.
