2. Eliminate Lower Inlet Modules and associated Bypass Flow Modules
3. Reduce core pressure drop
4. Eliminate hydraulic hold-down
5. Eliminate gas tagging and associated failed fuel monitoring system
6. Eliminate head shield
7. Replace ellipsoidal lower head with flat bottom
8. Bottom mount RV
9. Eliminate SRP
10. Adopt 10-year refueling interval
11. Eliminate RV volume reserved for in-vessel transfer
12. Eliminate CCPs
13. Eliminate IVTM
14. Eliminate IRP
15. Reduce EVST volume due to CCP elimination
16. Eliminate Containment to RSB hatch
17. Reduce size of RSB to a transfer room, fuel handling cell, and shipping room
18. Eliminate LRP (OVR)
19. Eliminate UIS jacking mechanism (OVR)
20. Eliminate transfer positions in RV
21. Eliminate need for valves mounted on RV and EVST (OVR)
22. Eliminate Plug Handling Machine (OVR)
23. Eliminate need for purging space between valves (OVR)
24. Eliminate EVTM (OVR)
25. Eliminate Auxiliary Handling Machine
26. Eliminate EVTM rails through containment and RSB
27. Use Superphénix steam generating system – eliminate separate evaporators and superheater, recirculation pumps, steam drum
28. The elevated unguarded PHTS piping concept is abandoned, permitting greatly reduced containment volume. IHXs are brought in closer to reactor reducing requirements for expansion loops
29. Centrifugal pumps are replaced with EM pumps in the primary and intermediate circuits.
30. Two primary loops down from three.
31. Elimination of requirement for pony motors on PHTS and IHTS pumps
32. Check valves are eliminated from PHTS.
33. Guarded PHTS piping eliminates need for liners on PHTS vaults.
34. Adopt rectilinear vs. cylindrical containment structure and eliminate the requirement for a single elevation basemat.
35. Significantly reduce containment volume
36. Eliminate requirement for single elevation operating floor. The requirement to have a floor that is accessible during operation inside containment is unnecessary.
37. Reduce containment design pressure from 10 psi to 5 psi or any pressure that will permit reliable leak testing
38. Eliminate separate confinement building
39. Eliminate containment cooling system
40. Eliminate air filtration processes that extend beyond CAPS
41. Eliminate all cell liners not required for containment leak testing
42. Significantly reduce 1E loads
43. Eliminate requirement for electric power to maintain safe shutdown
44. Eliminate requirement for IHTS and SGS to be safety related
45. Eliminate two Primary Sodium Storage Tanks in RSB, each having 60,000 gallon capacity
46. Reduce size of Overflow Vessel to size required to accommodate heat-up from refueling conditions to full power allowing margin for TOP transients at power.
47. Use HVAC cooling (vs. NaK) for the primary cold traps.
48. Combine primary system makeup pump drain vessel with primary system drain tank.
49. Elimination of tritium removal unit from CAPS
50. Eliminate unnecessary features from the IGRP system
51. Replace NaK with an updated version of Dowtherm J everywhere it exists in the plant, where possible.
52. Defer or eliminate radwaste system for treatment of effluent from the spent fuel cleaning facility.
53. Eliminate control rod ejection accidents from the design basis.
