Waterproof and thermal insulation sleeve and pool type reactor with waterproof and thermal insulation sleeve

Abstract

The invention discloses a waterproof and thermal insulation sleeve and a pool type reactor with the waterproof and thermal insulation sleeve. The pool type reactor comprises a pool, a pressure container, a reactor core and a sleeve, wherein the reactor core is arranged in the pressure container, and the pressure container is provided with a container inlet and a container outlet; the sleeve is fixedly installed in the pool and immersed below the liquid level of the pool; the pressure container is installed in the sleeve so as to be isolated from the pool; and the sleeve is provided with a through hole for a loop pipeline to penetrate through. According to the pool type reactor, the sleeve is sleeved outside the pressure container and the reactor core and can provide a waterproof space fora control rod drive mechanism so as to avoid inconvenience of underwater design or operation, play a role in thermal insulation of the pressure container and the reactor core, reduce heat exchange ofthe wall of the pressure container and reduce heat loss, and the sleeve can play a role in radioactive shielding of the reactor core and reduce radiation quantity, and has good safety and practicability.
