Calibration of a Modified Californium Shuffler

Sadowski, E.T.; Armstrong, F.; Oldham, R.; Ceo, R.; … - 2009

A californium shuffler originally designed to assay hollow cylindrical pieces of UA1 has been modified to assay solid cylinders. Calibration standards were characterized via chemical analysis of the molten UA1 taken during casting of the standards. The melt samples yielded much more reliable...

Empirical plutonium constants 7090 program

Jensen, R.D. - 2009

The current-revision of the Process Optimization Program contains two empirical plutonium-exposure expressions. One relates total Pu conversion to exposure and the other, Pu-240 buildup to exposure. The former was incorporated to save computer time and the latter to provide product quality data....

Automatic X-ray inspection for escaped coated particles in spherical fuel elements of high temperature gas-cooled reactor

Yang, Min; Liu, Qi; Zhao, Hongsheng; Li, Ziqiang; Liu, Bing - In: Energy 68 (2014) C, pp. 385-398

As a core unit of HTGRs (high-temperature gas-cooled reactors), the quality of spherical fuel elements is directly … related to the safety and reliability of HTGRs. In line with the design and performance requirements of the spherical fuel … elements, no coated fuel particles are permitted to enter the fuel-free zone of a spherical fuel element. For fast and accurate …
