Tech Spec 3.9 Refueling

Question 1

LCO 3.9.1 Boron Concentration

Answer 1

Boron concentrations of the reactor coolant system, the refueling canal, and the refueling cavity shall be maintained within the limit specified in the COLR

Mode 6

Question 2

LCO 3.9.2 Unborated Water Source Isolation Valves

Answer 2

Each valve used to isolate unborated water sources shall be secured in the closed position

Mode 6

Question 3

LCO 3.9.3 Nuclear Instrumentation

Answer 3

Two source range neutron flux monitors shall be operable

Mode 6

Question 4

LCO 3.9.5 RHR and Coolant Circulation - High Water Level

Answer 4

One RHR loop shall be operable and in operation

Mode 6 with the water level >23 ft above the top of reactor vessel flange

Note: The required RHR loop may be removed from operation for <1 hour per 8 hour period, provided no operations are permitted that would cause reduction of the RCS boron concentration

Question 5

LCO 3.9.6 RHR and Coolant Circulation - Low Water Level

Answer 5

Two RHR loops shall be operable, and one RHR loop shall be in operation

Mode 6 with the water level <23 ft above the top of the reactor vessel flange

Question 6

LCO 3.9.7 Refueling Cavity Water Level

Answer 6

Refueling cavity water level shall be maintained >23 ft above the top of reactor vessel flange

During movement of irradiated fuel assemblies within containment

Question 7

LCO 3.9.9 Spent Fuel Boron Concentration

Answer 7

Boron concentration of the spent fuel pool shall be > 2300 ppm

Whenever any fuel assembly is stored in the flooded spent fuel pool

Question 8

LCO 3.9.10 Decay Time

Answer 8

During movement of irradiated fuel assemblies within the containment
