NRC nominee Nieh commits to independent safety mission
During a Senate Environment and Public Works Committee hearing today, Ho Nieh, President Donald Trump’s nominee to serve as a commissioner at the Nuclear Regulatory Commission, was urged to maintain the agency’s independence regardless of political pressure from the Trump administration.

The RFX experimental results at the highest plasma current (about 1 MA) and for relatively long pulses (150 ms) show the presence of high power flux densities on the first wall, up to 40 MW/m2 averaged on a single tile.
Detailed numerical analyses have been carried out to simulate the thermal response of a single tile. The results of sensitivity analyses give information on the radiative and convective power flux intensities and the related first wall temperature distributions.
The experimental data and the results of thermal analyses give quantitative information and qualitative guidelines for the design of an optimized first wall for a RFP device.
