Design, build, and test devices to be used in a “hot cell” environment that removes molten salt from the Mark-V Electrorefiner and freezes it in appropriate sizes.
Specifications Process must remove at least 16,500 cm3 of salt in
one week Cubes can be no bigger than 2 inches by 2 inches by
2 inches to fit grinder

Problem:Spilling during transportation
Solution
Lid
11
Problem:
Remove smaller amount
Solution
Displacement Body
12
Problem:
Bucket holds 15,000 cm3
13
Problem:
Smaller footprint for tray
Solution
Folded Tray
14
We couldn’t make an actual prototype, so instead we made test apparatuses

Salt Release Plug
Test: See if salt releases from pocketResult: Salt released every time
Test: See if plug can be removed after salt gets in threads
Result: Plug was removed with greatdifficulty
17
Bucket SpillingTest: See if lid prevents spillingResult: Lid prevented spilling
Bucket EmptyingFull opened valve: 3 minutesControlled flow rate: 6.5 minutes
Tray SplashingFull opened valve: too muchControlled flow rate: very little
Tray OverflowTest: See if pockets fill before
overflowResult: Tends to overflow before all pockets are filled
18
Problem: Total volume of salt removed in bucket per cycle is only 15,000 cm3
Solution: Align valve handle so its vertical to increase room
Problem: Plug idea does not look promisingSolution: Test plug idea more or ditch idea altogether
Problem: Tray does overflow before all cubes are filledSolution: Put a ¼ inch or more lip around outside of tray
