Investment bill would provide funding options for energy projects
Coons
Moran
The bipartisan Financing Our Futures Act, which expands certain financing tools to all types of energy resources and infrastructure projects, was reintroduced to the U.S. Senate on February 20 by Sens. Jerry Moran (R., Kan.) and Chris Coons (D., Del.).
Via amendment to the Internal Revenue Code, the legislation would allow advanced nuclear energy projects to form as master limited partnerships (MLPs), a tax structure currently available only to traditional energy projects.
An MLP is a business structure that is taxed as a partnership but the ownership interests of which are traded like corporate stock on a market. Until the Internal Revenue Code is amended, MLPs will continue to be available only to investors in energy portfolios for oil, natural gas, coal extraction, and pipeline projects that derive at least 90 percent of their income from these sources. This change would take effect on January 1, 2026.

A technique for measuring the efficiency of a Ge(Li) spectrometer for gamma-ray sources in “gas bomb” geometries has been developed. The compounds of (CH3)2Se, CH3CH2Br, and CH3I are labeled with 75Se, 82Br, and 131I, respectively. These compounds readily vaporize at reduced pressure. The labeled compounds are flame sealed in small ampoules and the gamma-ray emission rates are measured. The contents of each ampoule are then released into the evacuated gas bomb and the efficiency of the detector for the gas bomb geometry is determined from the emitted gamma rays. The radionuclides of 75Se, 82Br, and 131I emit gamma rays that cover the energy range from 66 to ∼1900 keV without any large gaps. A method is suggested for measuring the efficiency for gas bomb geometries at small detector distances, which minimizes the effect of coincidence summing.
