Section: claims

1. A method for assessing failure of fuel rods, the method comprising:monitoring fuel rod operational conditions;calculating a plurality of fuel rod parameters from the fuel rod operational conditions, each of the fuel rod parameters reflecting a likelihood of failure of individual fuel rods;comparing each of the plurality of calculated fuel rod parameters to a corresponding parameter limit;modifying projected plant operational conditions, if at least one of the calculated fuel rod parameters exceeds the corresponding parameter limit, so as to reduce a degree to which the calculated fuel rod parameters exceed the corresponding parameter limit,receiving the modified, projected plant operational conditions from an operator if at least one of the calculated fuel rod parameters exceeds the corresponding parameter limit;repeating the calculating, comparing, and receiving steps, the calculating instead including calculating a plurality of fuel rod parameters from the modified, projected plant operational conditions and the fuel rod operational conditions if the at least one of the calculated fuel rod parameters exceeds the corresponding parameter limit; andmodifying plant operation based on one of the projected plant operational conditions and the modified projected plant operational conditions. 2. The method according to claim 1, wherein monitoring the fuel operational conditions includes collecting data of the fuel rod operational conditions at a regular time interval. 3. The method according to claim 1, wherein monitoring fuel rod operational conditions is in real-time. 4. The method according to claim 3, wherein monitoring the fuel rod operational conditions includes collecting data of the fuel rod operational conditions from a system consisting of at least one of a plant computer, a core monitoring system, a computer that is not linked to the plant computer, and through an Internet. 5. The method according to claim 1, wherein monitoring the fuel rod operational conditions is automatically performed without an operator. 6. The method according to claim 1, wherein the plurality of fuel rod parameters are calculated from a real-time operational conditions. 7. The method according to claim 1, further comprising:notifying the operator if the at least one of the calculated fuel rod parameters exceeds the corresponding parameter limit. 8. The method according to claim 1, wherein the plurality of calculated fuel rod parameters include at least one of stress, internal gas pressure, temperature, deformation, release of fission product gases, fuel swelling and densification, cladding thermal expansion, and cladding corrosion.
