(
1 Limerick Generating Station Unit 1 December 1 through December 31, 1985 I
I I.
Narrative Summary of Operating Experiences The unit began the month at approximately 70% power.
t On December 5, at 95% power, excessive isophase bus duct temperatures were discovered and power was reduced to 68%.
On December 8, the "B" Recirculation Pump speed demand meter was observed.to be of f-scale (reading low).
After locking up the scoop tube for inves tigation, the scoop tube lock was reset, resulting in a rapid speed increase, d
causing an Average Power Range Monitor ( APRM) Hi Flux i
i Scram.
With the generator of f-line, isophase bus duct j
minor modifications were completed including installation f
.. s -
I of temporary cooling f ans.
l, Unit startup began on December 9 and the turbine-generator was synchronized the same day.
On December 12, power was i
increased incrementally to monitor bus duct temperatur es.
At 82% power, the maximum bus duct temperatures were l
observed and power was immediately reduced to and maintained at 70% pending new bus duct installation.

Operating Report for i
December, 1985
}
Page 2 Ilj On December 18, power was increased to 914 briefly to
(
j support the full Main Steam Isolation valve (MSIV) closure (Startup Procedure 25-3).
This resulted in an anticipated
{
Startup recommenced on December 19.
Power was maintained at 10-15% on bypass valves while the new portions of isophase bus duct were installed.
On December 22, the l
turbine-generator was synchronized and power ascension to
~
954 began.
After setting the recirculation pump motor / generator set scoop tube electrical and mechanical
[
stops, reactor power was increased to 1004 (3291 MWt, 1114 MWe) on Deqember 26, 1985.
The unit ended the report period at approximately 98%
power.
