THERMAL EMISSION REACTOR-CONVERTER Russian patent published in 1995 - IPC

FIELD: nuclear power plants. SUBSTANCE: decrease of mechanical efforts on shells of electricity generating channels in process of operation of thermal emission reactor-converter and provision for performance of technological tests of tightness of cavity of heat-transfer agent of thermal emission reactor-converter at working temperatures till final assembly and increased serviceability of electricity generating channels and reactor-converter on the whole are obtained by compensation of difference of thermal expansion of vessel of reactor-converter and shells of electricity generating channels which clears this difference as cause of mechanical efforts on shells of electricity generating channels, and by formation in reactor-converter of additional gas cavity as means of realization of technological tests of tightness of cavity of heat-transfer agent of reactor-converter up to its complete assembly and relief of shells of electricity generating channels from effort created by pressure of heat transfer agent. Thermal emission reactor- converter has cylindrical vessel of active zone and electricity generating channels located inside vessel in parallel to its axis which shells are coupled over both butts of active zone with tube panels made with holes for current leads-out of electricity generating channels and which form together with vessel cavity of heat-transfer agent. Elements of electric commutation of electricity generating channels are arranged between butt parts of vessel and tube panels. Shell of each electricity generating channel is fitted on one butt with cylindrical corrugated restoring member through which coupling of shell with tube panel is carried out. Tube panel is manufactured in the form of barrel which bottom is coupled to vessel through corrugated partition and edge of cylindrical shell of barrel is connected to collar made in butt of vessel, through flat ring membrane attached over outer diameter to cylindrical shell of barrel and over inner diameter to collar of vessel. Cavity formed by corrugated partition, flat ring membrane, cylindrical shell and butt of vessel is filled with gas. Apart from that rigidity of flat ring membrane is chosen from expression specified in description of invention. EFFECT: reduced mechanical efforts on shells of electricity generating channels. 2 cl, 1 dwg
