InvestmentsThe U.S. Nuclear Regulatory Commission issued a construction permit on September 29 for Clinch River Unit 1, a 300 MWe GE Vernova Hitachi BWRX-300 planned by the Tennessee Valley Authority near Oak Ridge. World Nuclear News reported that TVA has not announced a construction date. At the permit ceremony, Tennessee politicians talked up work for welders and electricians. TVA’s chief executive said the utility does not yet have a specific job count for the project.
That gap is the story. The most-cited estimate for a single SMR facility is a 2020 Conference Board of Canada study, which link2build reported at an annual average of 1,600 jobs during manufacturing and construction and 200 jobs during operations. Those figures count direct, indirect and spin-off employment. The 200 is the number a host town lives with for decades, and most of it is not engineering. Here are five roles worth watching.
Security officers
Security officers are the largest non-engineering block on a nuclear payroll. A 2022 ScottMadden presentation to a National Conference of State Legislatures working group listed 48 security officers at an SMR plant against 20 at a coal plant. The extract does not state how many modules the SMR plant had, so read it as a ratio, not a forecast for any project.
The direction still holds. Nuclear sites carry staffing that coal sites do not. Idaho National Laboratory’s Light Water Reactor Sustainability program found that plant security workers have had the highest turnover of any nuclear job category. For a small town, that means continuous hiring rather than a single wave. If you sit on a county workforce board, ask the developer which security contractor it plans to use and what that contractor has committed to hire locally.
Electricians, pipefitters and instrument technicians
Skilled trades dominate the labor conversation. An American Nuclear Society commentary notes that the shortage of welders, pipefitters and electricians gets top billing in nuclear workforce debates. The ScottMadden slide shows why operating plants need them: 21 mechanical craft positions at the SMR plant against 12 at coal, 11 electricians against 5, and 10 instrumentation and control technicians against 9.
Construction is the harder case. SMRs move work into factories. A Thomas Thor analysis says the designs mean fewer workers building on site and more at the plants that manufacture reactors and components. Darlington shows the pattern. Nuclear News reported that BWXT Canada’s C$1 billion in OPG contracts created 350 jobs in Cambridge, Ontario, where the reactor pressure vessel is manufactured. Those jobs are not in Clarington. On site, IUOE Local 793 members are running excavators and rock trucks for the Darlington New Nuclear Project, which is excavation work, not nuclear work.
Radiation protection technicians
Radiation protection technicians measure exposure, control access to contaminated areas and keep the dose records regulators audit. Vault’s career profile says the usual route is a two-year program at a technical school or community college, and it points readers to the Nuclear Energy Institute’s training directory.
This is where lead time bites. When TVA filed its application, Power Engineering reported, it said the first reactor could begin operating around 2032. A two-year program started today still fits that window. One started in 2031 does not. If you run a community college program, the permit just made your enrollment case.
Plant operators
Many operators start as non-licensed operators and move up. Generation Atomic, a nuclear advocacy group, describes that ladder and says most roles do not require an engineering degree. Licensed operators need extensive training and an NRC license, which is a long road.
Operators also arrive late. The NRC permit allows construction but not operation, and TVA needs a separate operating license before fuel load. At Darlington, the preliminary schedule has the first BWRX-300 complete in 2028 and in commercial operation in 2029. Developers announce hundreds of jobs in year one. Operators typically get hired years later, and a town that expects them early will be disappointed.
Procurement, finance and compliance staff
The least glamorous category may be the tightest. The Department of Energy’s 2024 U.S. Energy & Employment Report ranks professional and business services as the second-largest employment category in nuclear, and 93 percent of employers reported at least some difficulty hiring in it. Generation Atomic lists accountants, communications professionals and project managers among the roles. A local accountant, paralegal or logistics coordinator who can clear a background check is a plausible hire. Every project, deal, company, and regulatory event we cover is logged, verified, and searchable in SMRbrief Pro.
Job claims also get softer the further they sit from the plant fence. At the Canadian Nuclear Association’s 2026 conference, Ontario’s energy minister cited 19,000 direct and indirect jobs from the Darlington program. That is a provincial figure for four units. It says little about how many of the roughly 200 operating jobs per facility go to residents of the host town, and nobody appears to be tracking it.
So who should own that number at Clinch River: TVA, the county, or the unions that will supply the trades?
