A BRAYTON CYCLE NUCLEAR POWER PLANT AND A METHOD OF STARTING THE BRAYTON CYCLE

摘要

A nuclear plant includes a closed loop power generation circuit which makes use of a Brayton cycle as a thermodynamic conversion cycle. The plant further includes a start-up blower system having an in-line valve and a blower connected in parallel with the in-line valve. Further a normally closed blower isolation valve is provided in series with the blower and a blower bypass arrangement in parallel with the blower. A method of starting the Brayton cycle includes bringing the power generation circuit into standby mode in which helium is circulated around the power generation circuit by the start-up blower system and increasing power generated in the power generation circuit until the helium is circulated around the power generation circuit by a compressor independently of the start-up blower system.
