ACRS seeking new committee member
The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) is currently seeking qualified candidates to fill an open committee member position. Applications for the position will be accepted until July 30. The ACRS is the world’s oldest organization devoted to reactor safety, and the group reports directly to the NRC’s commissioners in order to provide independent technical reviews of and advice on a wide variety of nuclear topics.

The diffusion coefficient for plutonium diffusing in isotropic pyrolytic carbon has been determined as a function of temperature. The apparent diffusion coefficient can be expressed by the equation D = 4.47 × 10’−8 exp(−55 0001R T) m2· s−1over the temperature range from 1273 to 2073 K. Evaluation and comparison of the plutonium diffusion data with that of uranium and thorium using a compensation law treatment resulted in a reasonably good correlation, thus implying similar diffusion mechanisms.
