Optimum Water Level for Spent Fuel Pool using MCNP Code

TRIGA reactor (RTP) has been operated for more than 30 years. Some of the part of the reactor become degraded by the time. Sooner or later, all these part either will be changed with a new part and proceed with upgrading plan or the reactor itself will be decommissioned. By that time, spent fuel pool (SFP) need to be ready to keep all the fuel from the core. The conceptual design of the SFP has been established. This paper will determine optimum water level to avoid any radiation hazard expose to the workers during managing the fuel later. This determination will use MCNP computer code. (author)
