Embodiment Construction
[0037] figure 1 Schematic diagram of the structure of the forced circulation cooling deep water pool heap comprising natural circulation designed for the present invention
[0038] Depend on figure 1 It can be seen that the reactor pool [1] is made of reinforced concrete, the inner wall is covered with a metal lining, the pool is filled with deionized water [12], the pool has a roof [11], and the space on the top of the pool [8] is normal pressure. The core [2] is installed at the bottom of the pool. The pool water enters the core from the bottom, flows out from the top of the core after being heated, and flows out of the pool through the radioactive attenuation cylinder [4] and the outlet circulation pipeline [7] of the radioactive attenuation cylinder. Enter the circulation pump [6] after cooling in the device [5], and then return to the pool. When the reactor is in normal operation, the control rod [3] is pulled by the driving mechanism [9] to control the reactor to work ...

The nuclear heating reactor with forced circualting cooling deep water pool containing natural circulation incldues water pool, reactor core, control rod and heat exchanger, in which the reactor core is placed in the bottom of water pool, the control rod is placed in the reactor core, the water outlet end of the heat exchanger is communicated with pool water by means of circulating pump, and the water inlet end of heat exchanger is communicated with reactor core. It is characterized by that the described heat exchanger and circulating pump are placed outsdie water pool, and the depth of pool water is 10-60m. and said circulating pump is an impeller circulating pump with high revolution rate. Said invention adopts forced circulation mode including natural circulation, and can implement non-active conversion under the condition of that the parameters of water temp. of reactor, etc. do not instantaneously overtop and can continuously change when the forced circulation is transited to natural circulation.
Description
Technical field: [0001] The invention relates to a forced circulation cooling deep water pool nuclear heating reactor including natural circulation, belonging to nuclear reactors [0002] technology field. Background technique: [0003] The deep pool nuclear heating reactor is a low-temperature heating reactor. This reactor works at a lower temperature and directly supplies the heat energy generated by nuclear fission to low-temperature users. It has a simple structure and is easy to build, but it requires a higher safety and reliability. There are many designs at present, and the closest to the present invention is the Chinese invention patent CN85100044, which is characterized in that the hydrostatic pressure of a relatively deep water pool is used to increase the water temperature at the core outlet, and a heat exchanger is installed in the pool to drive the natural circulation load by the temperature difference. the full power output of the reactor. It also mentioned ...
