- •
Only about 15% of UH3 is oxidised on its gradual exposure to oxygen.
- •
During the gradual exposure of UH3 to oxygen U3O8 rather than UO2 is generated.
- •
For such gradual exposure, predominantly H2 rather than H2O was generated.
- •
For the instantaneous exposure of UH3 to O2 the amount oxidised was variable.
- •
For these experiments, H2 + some H2O was generally produced.
- •
Pyrophoric or non-pyrophoric behaviour was related to “thermal runaway temperature”.
