RDW 3.6.1 Page 2 3.2 Equipment Description & Setup The resin transfer / dewatering control skid includes two air-driven, positive-displacement pumps, control valves, sample points and service connections. One pump is to be used to transfer the resin from the 14-195 liner to the 6-80 liner. The other pump is to dewater the 6-80 liner back to the 14-195 liner to maintain proper water to resin ratio for resin sluicing and to dewater the 6-80 in accordance with CNSI FO-OP-003.

8.0 OPERATING PROCEDURE 8.1 Initial conditions CAUTION: STRONG OXIDIZING AGENTS SUCH AS NITRIC ACID, WHEN IN CONTACT WITH ORGANIC ION-EXCHANGE MATERIAL AND IN THE PRESENCE OF AIR, MAY PRODUCE A SLIGHTLY DEGRADED RESIN IN AN EXOTHERMIC REACTION, UP TO AN EXPLOSION. THE FIRST INDICATION OF AN EXOTHERMIC REACTION DUE TO THE PRESENCE OF OXIDIZING AGENTS
- IS SOME FUMING AND A SLIGHT RISE IN TEMPERATURE ON THE OUTSIDE OF THE CONTAINER. IF THIS CONDITION IS FOUND WHEN DEWATERING A VESSEL, THE IMMEDIATE ACTION TO BE TAKEN IS TO REFILL THE VESSEL WITH WATER. THIS WILL ELIMINATE ONE OF THE INGREDIENTS NECESSARY FOR THE REACTION (AIR) AND WILL DISSIPATE THE MAJORITY OF THE HEAT, RETURNING THE TEMPERATURE OF THE VESSEL TO AMBIENT. THIS IS A STABLE CONDITION. THEN, YOUR IMMEDIATE SUPERVISOR MUST BE NOTIFIED.
8.1.1 The system has been installed per section 7.0.
8.1.2 The 14-195 liner with resin has been fluidized.
8.2 Operations 8.2.1' Place sluice wand in 14-195 liner if not already done.
NOTE: THE WAND MUST BE LOWERED SLOWLY TO AVOID PLUGGING.
8.2.2 Establish service air to air supply skid and to pumps. Adju,st air regulator to necessary level.
8.2.3 Open WS-1 and WS-2.
1 RDW 3.6.1 Page 7 8.2.4 Open air to P1 and adjust to necessary level to sluice resin.
8.2.5 Lower wand in resin as necessary to sluice and retain proper water to resin ratio.
CAUTION: EXPOSURE LEVEL ON PUMPS MAY RISE DRAMATICALLY.
CAUTION: CONTINUOUSLY MONITOR LEVEL IN 6-80 CASK BY INSTRUMENTATION OR VISUALLY.
8.2.6 Open DW-5 and DW-l.
8.2.7 Adjust air to P2 to maintain proper dewatering rate of 6-80 liner and to maintain proper water to resin ratio in 14-195 liner.
8.2.8 Continue transfer until high level alarm on 6-80 is indicated, then stop transfer and dewater 6-80.
8.2.9 If alarm is cleared and visual inspection allows more resin, repeat Steps 8.2.3 through 8.2.8 until 6-80 liner is full.
NOTE: WHEN RESIN NEARS UPPER THIRD OF 6-80 LINER, IT MAY BE (
ADVISABLE TO STOP OR SLOW DEWATERING, THIS WILL ALLOW THE RESIN TO LEVEL OFF AND AVOID THE COMING EFFECT. IT MAY BE NECESSARY TO ADD MORE DI WATER IN THIS EVENT TO KEEP THE RESIN IN THE 14-195 LINER SLUICABLE. IF MORE DI WATER IS ADDED, BE CAUTIOUS OF LEVELS IN BOTH LINERS. KEEP ADDITIONAL WATER TO A MINIMUM.
8.2.10 When transfer is complete, flush transfer lines by opening SW-4 and WS-1, then close WS-1 and open WS-2. Each hose should be flushed for 5 to 10 minutes. Be cautious of both liner levels.
l 8.2.11 Close all transfer valves and flushing valves - WS-1, WS-2 l and SW-4. l
)
8.2.12 Set up hoses as necessary for dwatering of 6-80 liner,per appropriate procedures (FO-OP-003) and continue until completion of same.
8.2.13 After completion of dewatering, remove all hoses and monitor cables as necessary to prepare cask and liner for shipment.
