Indiana Senate bill will have state consider SMRs
A new bill in the Indiana state Senate creates guidelines for state regulators to consider small modular reactors should utilities want to build them. Senate Bill 271 was sponsored by Sen. Eric Koch (R., Bedford), chair of the Senate Utilities Committee, and Sen. Blake Doriot (R., Goshen). Supporters of the bill said that SMRs could replace retiring coal plants and would supplement renewables.
The Indy Star reported on January 24 that the utilities committee passed the bill by a vote of eight to two and that it now heads to the full Senate.

Impurity spectra have been measured to evaluate impurity behavior and plasma parameter in the tandem mirror GAMMA 10. An ultraviolet and visible (UV/visible) spectroscopic system has been designed to measure the impurity emission intensity in detail. It consists of two spectrometers to obtain an entire wavelength range of UV/visible impurity spectra in one plasma shot. The time-varying emission intensity of radiation spectra have been measured successfully with electron cyclotron resonance heating (ECRH) or pellet injection plasmas. We evaluate radiation loss with ECRH from the GAMMA 10 plasma in the UV/visible range; further we estimate the electron density and temperature after applying the spectral intensity data measured from the pellet injection experiment to a collisional-radiative model.
