Time dependent start-up thermal analysis of a Super Fast Reactor

- Time dependent startup thermal analysis of a Super Fast Reactor is performed.
- A recirculation system is used for pressurization and for generating supercritical steam.
- MCST satisfies the criterion both during subcritical pressure and during power-raising.
- MCST is not sensitive to the change of inlet temperature, gap volume and flow rate because of high flow to power ratio.
- CHF is not limiting the MCST during subcritical pressure due to large margin of heat flux.
