Answer 8

Reactor shutdown
Loop cooled and depressurized
Loop pressure sources isolated by LOTO
Posting on loop primary and secondary cubicles
Posting on subpile room
Preop check of crane and rigging DOP-2.1.17
Radiation monitor setpoints

Question 9

What are the specific experiment removal loop preparations for 2E or MUCH (1C/D)?

Disconnect impulse lines
Remove Missile suppression plug

Question 10

What are the specific experiment removal loop preparations for PALM?

Answer 10

Install PALM lifting adapter
Disconnect TCs (alarm in LOCS)

Question 11

What is the weight of the TSP?

Answer 11

10,400 lb

Question 12

What is the purpose of the shield cylinder (donut)?

Answer 12

Restricts transient dose when transferring test.

Question 13

Why do we open crane disconnect prior to raising the experiment on the bayonet?

Answer 13

Prevents radiation exposure due to runaway crane (use chain hoist instead)

Question 14

What is the purpose of the Removal Sleeve?

Answer 14

Provide a waterfilled connection between the cask and the top head closure plate for removal of the test.

Question 15

What is the purpose of the top head rotoflex pump?

Answer 15

Removes excess water from the refueling ports and donut area.

Question 16

Describe ATR-1 Cask.

Answer 16

Sized for all tests - used for transfers within ATR (can’t leave the building)
Uses cable winch system with load tensioner.

Question 17

Describe TRC-1 and 2 Casks.

Answer 17

All stainless steel shielding (no lead)
More complex and time-consuming
Uses chain hoist with remote camera.

Question 18

Describe flushing of casks.

Answer 18

Cask is typically flushed if cask previously handled a fueled test and will be handling a non-fueled test
Always flush after use on 2A-C
Cask is set on catcher can for flushing.

Question 19

Describe shipping of TRC cask?

Answer 19

Move cask to storage stand.
Bolt on bottom shielding and plug assembly
Load onto transport for shipment to NRF

Question 20

Describe use of ATR-1 after loaded.

Answer 20

Move cask to CTS over empty storage can
Clear nozzle trench of personnel
Lower test into can (seated by activation of LOW LOAD alarm at 32 feet)D

Question 21

Describe lessons learned from ATR-1.

Answer 21

TRC spacer under storage can when using ATR-1 cask caused crushed can.

Question 22

What is the purpose of the hydrotest closure plug?

Answer 22

Allows loop to be pressurized without a test installed.

Question 23

What is the purpose of the configuration gauge check?

Answer 23

Verifies that closure sleeve locking ring has not backed out.
Verifies that closure plug locking ring is tightened.

Question 24

What action is required on a water on reactor top alarm from removal sleeve not sealing to IPT?

Answer 24

Start Reactor Top Pump

Question 25

What to do when IPT level Lo is received?

Answer 25

Fill cask with LDW (either hose or regular).
