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 core inlet enthalpy controlled core and its control system are proposed. This core can flatten the axial power distribution even at partial power and improves the core performance for startup operation 1 of boiling water reactor plants. The feedwater enthalpy is controlled to make the core inlet subcooling constant throughout the startup operation. With this control, the increase of axial power peaking in the lower part of the core at partial power can be suppressed. The core inlet enthalpy controlled core is expected to reduce the time required for the startup operation by about 38% compared with the core evaluated without inlet enthalpy control. The control system of the axial power distribution for the core inlet enthalpy controlled core can also be applied to the load follow operation.
