Several utilities have increased the output power of their nuclear power plant to increase their income and profit. Thus, the utility increases the power density of the reactor, which has other consequences. One consequence is to increase the depleti

Multi-group energy structure SHEM-281 and -361 were refined using a Contributon and Point-Wise Cross Section Driven method (CPXSD). The Contributon and Point-Wise Cross Section Driven method was derived based on the product of the forward and adjoint

Thorium-based fuels are investigated to improve fast reactor fuel burnup. Such new sources of fuel will have to ensure that the projected expansion of nuclear power is achieved in conjunction with a reduced risk of nuclear weapons proliferation. Thor
