Bill would require NRC reporting of nuclear medicine extravasations
Bipartisan legislation introduced into the U.S. House of Representatives earlier this month seeks to close a loophole that currently allows medical patients to be unintentionally exposed to radiation without reporting or disclosure. The Nuclear Medicine Clarification Act of 2025 (H.R. 2541) was introduced into the House by Reps. Don Davis (D., N.C.), Morgan Griffith (R., Va.), and Ben Cline (R., Va.), who said the legislation would improve care and ensure transparency for patients and simplify federal rules coming from the Nuclear Regulatory Commission.

Prior to becoming Principal Officer, Bob was responsible for leading all of MPR’s services to the nuclear power sector worldwide.
He graduated with honors from Duke University with a degree in Mechanical Engineering, and his career has focused on the technical details of the design and evaluation of nuclear power plants, maintaining this focus as he transitioned to company leadership.
During his career at MPR, he has worked on over 100 electric generating plants worldwide, including 58 of the 65 US nuclear power plant sites, with on-site work at 34 of the 65 US sites. He has also provided strategic technical and management support to key DOE projects and programs. His specific expertise includes work in the areas of system performance, safety analysis, and project management, as well as the design and development of new nuclear power plants. Mr. Coward participates on key industry leadership committees and is recognized as a key industry leader in the safe and reliable operation of the existing US nuclear power plants. He has also had important and influential industry roles in the design, licensing and development of new nuclear power plants, with leadership roles on the EPRI Advanced Light Water Reactor Program, the DOE NP2010 Program, the STP 3&4 ABWR project, as well as the NuScale and other new plant programs.
As Principal Officer of MPR, Mr. Coward regularly engages with nuclear industry executive leadership to be knowledgeable of industry needs and guide MPR to address those challenges and contribute to industry success. Mr. Coward regularly serves on “blue ribbon panels” in support of clients and industry groups addressing important design, regulatory, and operational challenges regarding advanced reactor systems, extended power uprates, safety system performance, significant event evaluations, and new plant projects. A particular skill is leading multi-organization and multi-discipline teams to achieve their missions and deliver excellence, with a focus on collaboration and teamwork.
Finally, a focus of Mr. Coward’s efforts in his leadership role at MPR is the professional development of the MPR technical staff, including both technical expertise and leadership capabilities.
