- ⚠️ Radiation-induced embrittlement of conventional alloys in neutron flux fields
- ⚠️ Flow-accelerated corrosion (FAC) of carbon steel in high-velocity steam/water
- ⚠️ Hydrogen embrittlement of steel at 700+ bar hydrogen pressure
- ⚠️ Cryogenic brittleness of standard steel at -253C liquid hydrogen temperature
- ⚠️ Alpha case formation during hot forming causing premature fatigue failure
2 Material Selection Rationale
Grade 2 CP-Ti — Industrial pure Ti, general corrosion resistance
Grade 2 CP-Ti for condenser tubes, fuel pool liners, and general nuclear service — zero corrosion in seawater/cooling water, no FAC, no radiation embrittlement. Grade 5 for pressure-containing components, hydrogen valve stems, and spent fuel cask bolts. Grade 23 ELI for cryogenic hydrogen service requiring fracture toughness at -253°C. Grade 7 for radioactive waste evaporator coils requiring extreme acid resistance.
3 Form Selection Rationale
Seamless Tube — for fluid systems, heat exchangers
Seamless tube for condenser bundles and hydrogen piping. Heavy plate for fuel pool liners. Forged bar for valve stems and cask bolts. Forged/rolled rings for flanges and connectors.

Process Pitfalls:
- ⚠️ Hydrogen service requires surface finish Ra<0.8um to prevent hydrogen molecule trapping at surface asperities
- ⚠️ Nuclear-grade Ti must have low Co content (<0.05%) to minimize activation under neutron flux
