Comparison of DYN3D results with reference solution for the NEA-NSC benchmark - Case D:
Uncontrolled withdrawal of control rods at hot zero power: |
|
Hot pellet fuel enthalpy |
- OECD Main Steam Line Break (MSLB) Benchmark:
Break of main steam line with shut down of the reactor. One stuck rod assumed. Consideration of reduced efficiency of control rods in exercise 2 leads to recriticality. DYN3D result for nuclear power:
Maximum linear rod power of fuel assemblies:
Initial state | After shut down | At the moment of recriticality |
