DEVICE FOR CONTROLLING HEAT RELEASE IN THE CHANNEL OF NUCLEAR REACTOR ACTIVE ZONE

摘要

“A DEVICE FOR REGULATING THERMAL DEPARTMENT IN THE CHANNEL OF AN ACTIVE ZONE-NUCLEAR REACTOR, where the test device is located, containing a shell filled with a neutron-absorbing, for example, gaseous substance and system, providing a change in the concentration of the core – chrompastech-chromphanechist, such as a gas-form substance and the system providing the change in the concentration of the core –––––––––––––––––––––––– developer - characterized by the fact that, in order to increase the reliability and efficiency of regulating the gadget in the channel, a block of neutron-transparent ogre substance is placed inside the shell in the core area. For example, pyrolytic graphite with a crystallographic axis * "C" parallel to the channel axis, and a reservoir outside the core with a neutron absorbent material, which are combined into an autonomous evacuated volume and provided with heaters to control the specific content of the neutron absorber .2. The device according to Claim 1, about tl and - the fact that, as a neutron-absorbing substance, use is made of substances that form bio-compounds with pyrolytic graphite, for example, methyl bromide .§ (OCbcd00'so co) &
