Ways of solving some engineering problems in arrangement of integral and loop type fast reactors

A comparative analysis of currently-in-use and feasible arrangements of loop and integral LMFBR type reactors is given. The discussion is based on the designs of ''in operation'', ''under construction'' and ''projected'' reactors all over the world. The effects of the outlet coolant temperature, reactor unit power, maintainability and costs on the choice of the arrangement type are considered. Considered in greater details are the hydraulic schemes and problems of the integral reactor vessel attachment as well as problems of ensuring strength of pipe-to-vessel connections and localizing coolant leaks in the loop type reactors. There is no general consent over the superiority of one of the designs up to now. There are different opinions on the account in different countries, since both designs have its merits and shortcomings
