Description
The fast neutron fluence is 1.3 times larger in the 'JOYO' MK-III core than in the MK-II core. To achieve this, the fuel region was expanded, two of six control rods were shifted, and reflector subassemblies were replaced by shielding subassemblies in the outer two rows. To accommodate the resulting 40% power increase, the sodium coolant flow rate in the primary system was increased, and the two intermediate heat exchangers and four dump heat exchangers were replaced. MK-III function tests were successfully conducted from August 2001 to March 2003 and the performance of the primary and secondary cooling system; flow rate of the dump heat exchangers, preheating of the intermediate heat exchangers, sodium purity, operability of cooling loops, core flow distribution, etc. was confirmed to be satisfied with the design criteria.
