FUEL ROD, BOILING WATER NUCLEAR REACTOR WITH THESE FUEL RODS AND NUCLEAR POWER PLANT BASED ON SUCH TYPE OF NUCLEAR REACTOR USING

摘要

FIELD: nuclear power energy plant engineering. SUBSTANCE: fuel rod has envelope made like parallelepiped, which grate sides have height and width more than 600 times exceed same parameters of little sides. Besides, bigger sides are made wave-shaped, and theirs external surfaces are covered by layer of nuclear fuel. Fuel rods are installed one parallel to another with separations between them in nuclear reactor body and they are jointed from above and from below by bridgings. There are two separate hermetically spaces inside reactor body, which one is filled by water and it includes fuel rods free space, water cooling area and gas area between fuel rods composing gas circulation loop. Plant has pressure leveler equalizers made like pressure-tight vessels connected with reactor water pipe line and heat gas-carrier pipe lines. For gas transfer from gas circulation loop to tank gas compressor is used. EFFECT: higher efficiency and reliability of nuclear power plant.
