Abstract

The marine nuclear power platform is an organic combination of small nuclear reactor and ship engineering technology. It has the characteristics of good manoeuvrability, long on-time charging operation cycle, high power density, low operating cost, energy saving and environmental protection. In this paper, The core geometry model is built based on the design of the marine nuclear power platform reactor core. The core reactivity and control rod worth are calculated by a Monte Carlo code MCNP for this core design at first cycle, initial loading, normal temperature, and normal pressure condition. The results of the calculation are compared with nuclear design values. It shows that MCNP code is suitable for marine nuclear power platform core design calculation, and can be verified with nuclear design values.
