SUMMARY
JULY 1987 UNIT TWO The unit began the month at 100% full. power.
At 1506 hours0.0174 days <br />0.418 hours <br />0.00249 weeks <br />5.73033e-4 months <br /> on the sixth, a unit shutdown was initiated due to a leak at a pressurizer heater plug weld.

February 1988 7
3.
Scheduled date for restart following refueling. March 1988 3
4.
Will refueling or resumption of operation thereafter require a 3

Important licensing considerations associcted with refueling, e.g., new j
or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating
{
procedures.
A debris resistant, ended solid end cap design will be used in the Fresh Fuel batch for cycle 7.
