In power reactors, the coolant flows from the reactor to a steam generator, where steam is produced to drive the turbine. Alternatively, the coolant itself, whether steam or gas, may serve as the working fluid for driving the turbine. In research reactors, such as materials-testing reactors,...
Firstly, because it is lack of seal shaft and the supporting system, the structure of a canned motor pump could be more compact. Secondly, enhanced safety could be realized since seal shaft is a potential source of coolant leakage. Canned motor pumps have a long history of safe, reliable ...
The test rig is a closed circulation system equipped with pressure pump, flow control valve, cavitation tank, surge tank and the pipes, as shown in Fig. 2. The model RCP is driven by a three-phase asynchronous motor controlled by a frequency converter. An annular pressure equalization method...
