Holtec pulls out of New Mexico SNF interim storage project
Holtec International has confirmed it is canceling plans to build a consolidated interim storage facility for spent nuclear fuel in southeastern New Mexico. Named the HI-STORE CISF, the facility would have stored up to 10,000 canisters of commercial SNF on land owned by the Eddy-Lea Energy Alliance (ELEA) near the towns of Carlsbad and Hobbs.

Systematic, multiple initial value simulations are performed for a toroidal plasma using the recently updated MARS-F code in order to understand how the resistive wall mode (RWM) can be feedback controlled in the presence of control coil voltage saturation and/or sensor noise. The former renders the control nonlinear, thus generally requiring initial value computations for toroidal plasmas. This numerical study complements and confirms the key results from a previously analytic investigation of the RWM feedback with power saturation for a cylindrical plasma [Li et al., Physics of Plasmas, Vol. 19, 012502 (2012)]. Moreover, simulation results reveal a linear trend between the maximum tolerable sensor noise level and the degree of relaxing the control coil voltage saturation requirement, up to a certain level of noise, corresponding to a noise-to-signal ratio of about 25%. Beyond this level, further relaxing the control voltage saturation limit does not lead to increased sensor noise tolerance for the RWM stabilization.
