1 CALLAWAY PLANT i
DOCKET NUMBER 50-483 REVISION TO TECHNICAL SPECIFICATION
Reference:
ULNRC-2450 dated July 30, 1991 Union Electric Company herewith transmits an application for-amendment to Facility Operating License Number NPF-30 for the Callaway Plant.
This amendment-
{
involves a revision to Technical Specifications 3.7.1.1 i
(Tables 3.7-1 and 3.7-2). Tables 2.2-1 and 3.3-2, and Bases 3/4.7.
t Table 3.7-1 is revised to limit the maximum i
allowable power levels with inoperable main steam line safety valves.
j Table 3.7-2 is revised to~specify that the lift setting toleranceLfor the main steam'line safety valves is
+3/-1% as-found and 1% as-left.
3 Tables 2.2-1 and 3.3-2 are revised by reducing l
the sensor error and the response time for the pressurizer pressure-high trip.
Revising _these items in this manner provides. margin to relax the setpoint tolerance for the, j
main; steam line safety. valves-1 Bases 3/4.7.1'is revised as'a result ~of_the plant uprating and switch to V5 fuel.
Therefore, this' letter j
1 updates 1and supersedes the changes.previously submitted by
_j letter dated July 30, 1991.(ULNRC-24 50).
This Bases section is further-revised to incorporate the methodology j
used to determine the maximum allowable power level with inoperable' main steam line safety valves.
