New company has big nuclear plans
The recent startup The Nuclear Company announced plans this month to deploy a series of nuclear reactors by the mid-2030s using a “design-once, build-many approach.”
The venture-capital-funded firm wants to use proven, licensed technology and target sites that already have some level of licensing approval from the Nuclear Regulatory Commission to build enough reactors to produce 6 gigawatts of electricity across the country.

Tokamak plasmas can be sensitive to external nonaxisymmetric magnetic perturbations that are several orders of magnitude smaller than the axisymmetric field. These perturbations, which are usually undesired and are referred to as error fields, can limit operation by braking the plasma rotation until an instability such as a tearing mode, a resistive wall mode, or an error field-driven locked mode leads to an unacceptable confinement degradation or a disruption. Auxiliary heating can have two competing effects: On one hand higher leads to a degradation of the error field tolerance through plasma amplification and stronger braking, and on the other hand higher toroidal rotation can tolerate a higher magnetic braking torque. A widely used technique to detect and correct error fields is based on the characteristic density dependence of the error field tolerance in ohmic plasmas. An alternative technique is based on the measurable plasma amplification of the error field in high- plasmas. However, the detection and correction of error fields in ITER will require a modification of the present techniques in order to avoid disruptions and deal with insufficient plasma amplification of the error field at low , before the full set of auxiliary heating systems will be available. The adaptation of current techniques to address these concerns is likely, but an experimental demonstration as well as an improved physics basis is needed and remains the subject of current research.
