State max capacity of new fuel vault
90,
81 for high enrichment assemblies
State basis for T.S. 3.9.11 for 23’ of water over fuel
removes 99% of the assumed 10% iodine gap activity released from the rupture
State raise interlock for new fuel elevator
This prevents raising the elevator when loaded
State the proximity switches for the upender
Carriage at RX Carriage at Pool Frame up Frame Down Gate valve
Discuss the Refueling machine interlock over-ride features
SM and SRO agree to use
Refueling SRO directly supervises all actions
Each use of the interlock override is communicated to the CR
A spotter observes all movements
interlock override key needs to help in bypass
RFM operator need to monitor height/weight continuously during interlock override operation

At least 1 train of RHR must be in service other wise Immediately suspend core alterations
State RHR requirements when refueling and cavity level is <23’ (T.S. 3.9.8.2)
Two loops have to be operable and one in service when <23’
State when >23’ of water is required in the refueling cavity (T.S. 3.9.10)
