A Scheme for Establishing of Criterions for Reactor Safe Operation in Condition of Fuel Clad Failure

Operation criterions are used to decide if the reactor can continue to work when the fuel clad failure.The method for establish the limits is presented.The tolerated maximum of failure fuel rods for the reactor safety should be calculated by risk analysis.The parameters are determined which can not only reflect the quantity but also be measured directly.The relationship is set up between the amounts with the parameters.The data calculated corresponding to maximum of failure fuel element which the reactor safety can stand are technical limits used to decide if the reactor can work continually.
