Reduction cylinder for deep pool type low-temperature heating reactor

Abstract

The invention relates to a reduction cylinder for a deep pool type low-temperature heating reactor. The reduction cylinder comprises a cylinder body provided with a water inlet and a water outlet; thewater outlet is connected with a loop main pipeline; an internal partition plate capable of prolonging reduction time of fluid in the cylinder body is arranged in the cylinder body. The reduction cylinder has the advantages that the internal partition plate buffers fluid at the water inlet, flowing time of the fluid in the cylinder body is prolonged, and therefore the reduction time of cooling water is effectively prolonged.

Description

technical field [0001] The invention relates to the field of nuclear technology, in particular to an attenuation cylinder for a deep-water pool type low-temperature heating reactor. Background technique [0002] In the design of the deep-water pool low-temperature heating reactor, an attenuation cylinder device needs to be used, so that the radioactive nitrogen-16 produced in the core can be greatly attenuated when passing through the decay chamber, and finally the radioactivity level of the primary pump room is higher than that in the no Attenuates by 4 orders of magnitude when decaying the box. The attenuation cylinder is placed inside the pool of the deep-water pool-type low-temperature heating reactor as a whole, and its inlet and outlet are respectively connected with the outer cylinder of the hanging basket under the core and the primary circuit pipeline. A reasonable baffle structure is set in the attenuation cylinder, which can Sufficiently extend the decay time of ...
