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.

The consequences of decarburization on the creep properties of 2.25 Cr—1 Mo steel have been analyzed. First, a relationship between the creep rate and the carbon concentration as a function of temperature and stress is developed. Then, using this relationship in conjunction with decarburization models developed, creep deformations under typical operating conditions of the steam generator tubings for realistic and pessimistic rates of decarburization are calculated. The results obtained show that the effect of decarburization on the creep deformation level is a function of the operating temperature and the tube dimensions. However, creep deformations remain limited, principally due to redistribution of effective stresses across the tube wall and the fact that stresses are lower on the sodium side where decarburization is more important.
