Concept of a Single-circuit RP With Vessel Type Supercritical Water-cooled Reactor

Abstract

The first thermodynamic, thermal-hydraulic and computational investigations for the Single-Circuit RP VVER-SCP were performed in SSC RF IPPE beginning in 2001. In 2006 OKB "GIDROPRESS" launched the design works and computational analyses to corroborate this innovative RP concept.  The purpose of a RP VVER-SCP is an effective electric power generation by the NPP Unit. Other key purposes of this design are a rise in the breeding factor and a reduction in the natural uranium consumption for effective application of VVER-SCP in the closed nuclear fuel cycle. The description will be given for the concept of single-circuit RP VVER-SCP with vessel type supercritical water-cooled reactor. Two versions of coolant flowing in the core will be considered: single-pass and two-pass flowing. Results of neutron-physics and thermal-hydraulic calculations will be presented. The description of the structure of safety systems will be given. Problematic issues of VVER-SCP will be listed.
