1
New cards

per 3.9.1 mode 6, what ppm concertation is required in the RCS and refuel canal and what actions are taken if its not met?

at least 3000 PPM, if not met immediately stop core alts, pos reactivity additions and restore within limits

if necessary borate from a 4000 ppm source at 26 GPM

2
New cards

what are Keff limits during fuel handling?

keep Keff under 0.95 during fuel handling

3
New cards

during mode 6 how many SU NI channels are required and what actions are taken if it cant be met?

Two SU channels required

one inoperable immediately suspend core alts and pos reactivity additions

of two inoperable immediately restore

continuous visual indications in the MCR

a loss of audible indication in both the MCR and CTMT makes both channels inoperable

4
New cards

what are the 3.9.3 requirements for the containment hatch?

must be closed and held in place by 4 bolts or if open, capable of being closed within time to boil or in 30 minutes, whichever is more restrictive

5
New cards

what is required for the air lock doors?

one door in each air lock must be capable of being closed

6
New cards

what is required of each penetration that provides direct access from CTMT to outside atmosphere?

closed by a manual or auto isolation blind flange or equivalent

OR capable of being closed by CPIAS and meet stroke times

7
New cards

what is required if any of our containment penetrations can not be met?

suspend core alts and stop fuel moves

8
New cards

what is the purpose of LCO 3.9.3 containment penetrations?

maintains 10CFR100 limits less than 25% during a FHA

9
New cards

what are our HI water level tech spec requirements?

if mode 6 water must be at least 23 ft above vessel flange

one SDC loop in operation and greater than 3780 GPM

10
New cards

during HI water level how often and under what conditions can a SDC loop be removed from operations? why would we do this

can be removed from operations for 1 hour every 8 hours provided that there are not dilutions

allows core mapping and alterations near hot leg nozzles, ST of SI pumps, and RCS to SDC isolation valve testing

11
New cards

what is the required water level for low water level operation?

less than 23 ft above the vessel flange

12
New cards

during low water level operation how many SDC loops must be operable and what is the minimum flow and lineup

2 operable

1 operating at at least 3780 GPM

13
New cards

when in Low water level operations how long can you take one loop if SDC inoperable

one loop may be inoperable for up to 2 hours for surveillance testing

14
New cards

what is required when in low water operations and one loop becomes inoperable? what if both loops become inoperable

immediately restore SDC operability OR raise level to greater than 23 ft above vessel flange

if both loops inoperable then immediately restore and stop dilutions

15
New cards

when is water required to be 23 ft above the top of the reactor vessel flange?

during fuel movements within CTMT, if not met, stop all fuel movements

this retains iodine (99%) fission produce during a fuel handling accident and limits offsite dose during a fuel handling accident to less than 33% per 10CFR100 limits

16
New cards

how long must we be subcritical prior to moving irradiated fuel

subcritical for 100 hours

17
New cards

how is communications maintained during a fuel movement

constant communication with MCR and CTMT met during core alts, if not met suspend all core alts

18
New cards

what is the maximum load that can be moved over the fuel pool

loads greater than 2000 pounds are prohibited

if not met place crane in safe position

19
New cards

how many trains of FBEVAS are required during fuel movements? what is required if this is not met?

two trains are required

if one is inop then restore in 7 days and make sure operable train is capable of being powered from EDG. if not met in 7 days place it in service

if both inop then stop all fuel moves
