A fuel bundle temperature sensing device may include an indicating rod made of a first material; an outer housing having an upper opening, the outer housing being made of a second material and surrounding at least a portion of the indicating rod; and a rod holder attached to an inner surface of the outer housing, the rod holder being made of a third material and being configured to support the indicating rod such that a top surface of the rod extends out of the upper opening of the outer housing, the third material having a lower melting point than the first and second materials.

Passive visual fuel temperature indicator

A method for storing nuclear fuel includes transferring a fuel assembly from a long term storage vault to a nuclear reactor core, removing the fuel assembly from the nuclear reactor core, determining a heat generation rate of the irradiated fuel assembly, and transferring the irradiated fuel assembly to one of an interim storage vault and a long term storage vault based on the determined heat generation rate.
