Title: Conditioning nuclear reactor fuel elements
IPC: G21D3/00
Filed: 1975-04-10
Abstract: 1506436 Nuclear reactor operating procedures GENERAL ELECTRIC CO 10 April 1975 [12 April 1974] 14796/75 Heading G6C Fuel elements in a nuclear reactor are conditioned to withstand rapid power changes without cladding failure by a method which comprises increasing, at a rate of power increase below a critical rate which causes cladding damage due to a fuel pellet-cladding interaction, the power produced by said fuel elements, said increase being conducted through a fuel pellet-cladding interaction range of power and up to a desired maximum power level. The critical rate for any given fuel element depends upon fuel pellet diameter and fuel cladding thickness; an equation giving the relationship is provided. For fuel pellets of about 0À49 inch diameter, the critical rate is about 0À125 kilowatts per foot per hour. By reference to examples, the Specification illustrates how the use of power increases at rates below this critical rate-preferred rates are in the range 0À08 to 0À1 kilowatts per foot per hour -fuel element failures during subsequent rapid power changes are minimized or eliminated. The increases in power conducted through the fuel pellet-cladding interaction range of power may be continuous, although as particularly described they are conducted stepwise. Limits on the size of each step are given. Fuel pelletcladding interaction is stated to occur in the power range 6 to 10 kilowatts per foot. Conditioning by the method described is stated to produce in the fuel element a capability of undergoing rapid power changes of the order of 15% of rated power per minute, without under going cladding failures. The method of the invention is described in its application to a boiling water reactor.
