This study focused on the preparation of metallic uranium and uranium-zirconium alloys to measure the effect significant porosity had on thermal diffusivity from 20∘C to 300∘C. Precursor uranium powders were prepared through a hydride de-hydride

A high-speed option for a time-tested radiation pyrometer has been made available. The response time for 98% response is less than or equal to 0.5 second. It is compensated for ambient temperature effects, is transient free, and makes use of existing
