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.

Wave propagation around the ECR layer in the GAMMA 10 plug region is analyzed by calculating the dispersion relation of an electron cyclotron wave in a hot plasma. Then, the spatial distribution of microwave power deposition and the absorption rate along each microwave ray are calculated. The absorption rate is experimentally evaluated by using an array of waveguide antennas. The calculated value well agrees with the experimental one on reasonable assumption that the extraordinary mode shares about 90% of the injected microwave power. This analysis is used to obtain an axisymmetric power deposition distribution. It is shown that the heating wave should be directed somewhat upward than the direction to the on-axis point on the resonance layer. This is because a larger power is deposited in the injection side lower side to the machine axis. For the plug in GAMMA 10, an injection beam with an elliptic cross section is suitable to obtain a circular distribution of power deposition.
