State 3.4.3 RCS Pressure and Temperature (P/T) Limits and
applicability. Correct Answer LCO 3.4.3 RCS pressure, RCS
temperature, and RCS heatup and cooldown rates shall be
maintained within limits (AT ALL TIMES)
State LCO 3.4.1 RCS Pressure, Temperature, and Flow
Departure from Nucleate Boiling (DNB) Limits and its
applicability. Correct Answer RCS DNB parameters shall be
within the limits specified in the COLR. (MODE 1)
State LCO 3.4.10 Pressurizer Safety Valves and its applicability
Correct Answer LCO 3.4.10 Two pressurizer safety valves shall
be OPERABLE. Note:
1. Only valve is required MODE 3 and 4 Tave > 259 °F.
2. The lift settings are not required to be within limits for entry
into MODE 3 or 4 to set the settings ambient (hot) conditions.
This exception is allowed for 36 hours following entry into
MODE 3
3. Not applicable in MODE 3, and in MODE 4 with RCS
temperature > 259 °F during hydrostatic tests
4. The provisions of LCO 3.0.3 are not applicable in MODE 3,
and in MODE 4 with RCS temperature > 259 °F.
APPLICABILITY: MODES 1, 2, and 3, MODE 4 with RCS
temperature > 259 °F.
, State LCO 3.4.11 Low Temperature Overpressure Protection
(LTOP) System and its applicability Correct Answer LCO
3.4.11 An LTOP System shall be OPERABLE with:
HPI deactivated and CFTs isolated and either:
PZR not water solid and ERV with a setpoint of </=508#
OR
The RCS depressurized and the RCS open.
(NOTE :
-HPI deactivation and CFT isolation N/A during ASME testing
-HPI deactivation N/A during fill and vent of the RCS
-HPI deactivation N/A during emergency RCS makeup
-HPI deactivation N/A during valve maintenance
-CFT isolation required when CFT pressure is >/= Max RCS
pressure for existing RCS temperature allowed)
APPLICABILITY: MODE 4 with RCS temperature </=259 °F,
