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.

AI Technical Summary

Problems solved by technology

Among them, the nuclear reactor includes a pressure vessel and a core. At present, the installation stability of the pressure vessel of many nuclear reactors is poor, and the insulation effect on the interior of the core is not good.

If the nuclear reactor is located underwater, the control rod drive mechanism is installed outside the pressure vessel and soaked in water. Not only is it difficult to operate, but long-term immersion may easily cause structural damage to the control rod drive mechanism, and the stability and reliability will decrease. There is room for improvement.
