Reactor design concept and main data

The BN-600M power unit is being developed as a monoblock i.e. an integrated power unit involving the reactor and a single turbine with a 647 MW(e) generator. The 

The major portion of the refuelling mechanisms used in BN-600 and BN-800 has been borrowed for BN-600M. However the refuelling complex has been modernised to reduce the number and weight of equipment items. In particular the number of positions in the in-reactor spent fuel store has been increased to hold the FAs from two fuel cycles. This allows the FA residual power at unloading to be reduced to 1.5 kW, so that they can be transported for washing without additional delay in the external fuel storage drum used in BN-600 and BN-800. The drum itself is not reauired. 

The main design data are given in Table 9.3. BN-600 are given for comparison.
