Experimental investigations into the possibility to operate steam generation systems of nuclear propulsion prototype plants when pressurizer system integrity is lost
The paper reports results obtained from experimental operation of the steam generation system in the nuclear propulsion prototype plant with pressurized water reactor under conditions where the pressurizer system integrity is lost. The results demonstrate that the steam generation system remains operable when some or even all groups of high-pressure gas system (HGPS) cylinders are disconnected from the primary circuit. The experiment results can be used to support the possibility of continuing to operate steam generation systems of nuclear propulsion plants in case of pressurizer system non-integrity and, thus, expand the applicability conditions of these systems at nuclear-powered submarines and surface ships in active service.
