NRC completes environmental review of Dresden SLR
The Nuclear Regulatory Commission has found that the environmental impacts of renewing the operating license of the Dresden nuclear power plant outside Chicago, Ill., for an additional 20 years are not great enough to prohibit doing so.

A millimeter-wave notch filter with 105-GHz center frequency, >20-GHz passband coverage, and 1-GHz rejection bandwidth has been constructed. The design is based on a fundamental rectangular waveguide with cylindrical cavities coupled by narrow iris gaps, i.e., small elongated holes of negligible thickness. We use numerical simulations to study the sensitivity of the notch filter performance to changes in geometry and in material conductivity within a bandwidth of ±10 GHz. The constructed filter is tested successfully using a vector network analyzer monitoring a total bandwidth of 20 GHz. The typical insertion loss in the passband is <1.5 dB, and the attenuation in the stopband is [approximately]40 dB.
