Plain English Summary

AI-GENERATED
Puts the Public Service Commission in charge of advanced nuclear reactors.

The bill gives the Public Service Commission authority to regulate advanced nuclear reactors statewide, requiring state permits before anyone transfers, stores, or uses nuclear materials, and certification before building or modifying a reactor.

A reactor that replaces an old power plant, or adds no more than 75 megawatts, at an already-certified site skips the full state siting-certification process, unless the developer opts in.

An advanced reactor built purely for private use, not connected to Florida's power grid, skips the standard preliminary-review report and the commission's proceeding on whether a new plant is even needed.

When regulators weigh whether Florida needs a new power plant, they must now consider nuclear energy use instead of renewable energy use; the state's renamed clean energy policy now counts nuclear power as clean.

KEY PROVISIONS
§ 1 Grants the Public Service Commission authority over advanced reactors majors. 403.541

AIThe bill hands the Public Service Commission direct regulatory authority over advanced nuclear reactors in Florida, including evaluating and approving reactor designs and prescribing safety and construction standards, in consultation with a University of Florida nuclear materials facility.

“The authority to regulate advanced nuclear reactors in this state is granted to the commission.” bill text, line 87 →
§ 2 Requires certification before building or modifying a reactor majors. 403.541

AIA Public Service Commission permit is required to use or store nuclear materials for reactor research and testing, and any advanced reactor's construction or significant design change must be certified by the commission before work may begin.

“The construction or significant design modification of an advanced nuclear reactor must be certified by the commission before such construction or modification may begin.” bill text, line 145 →
§ 3 Authorizes possessing nuclear material for reactor work, within limits majors. 403.541

AIA person, corporation, or entity may hold nuclear materials needed for advanced-reactor research, design, testing, construction, or operation, but not in amounts that would endanger national defense, security, or public health and safety.

“A person, corporation, or entity may possess nuclear materials for, and in quantities sufficient to facilitate, the research, design, testing, construction, and operation” bill text, line 124 →
§ 4 Exempts small reactor swaps at certified sites from full siting review majors. 403.506

AIA reactor that replaces an existing unit, or that adds no more than 75 megawatts in the aggregate, at a power plant site already certified under the Florida Electrical Power Plant Siting Act skips that certification process, unless the developer elects to seek it anyway.

“Capacity expansions of 75 megawatts or less, in the aggregate, of one or more advanced nuclear reactors as defined in s. 403.541” bill text, line 265 →
§ 5 Exempts off-grid reactors from preliminary review and need proceedings majors. 403.507

AIAn advanced reactor that will not connect to Florida's electric grid is excused from the standard preliminary statement-of-issues report and from the commission's determination-of-need proceeding that other new power plants must go through.

“This subsection does not apply to an application for an advanced nuclear reactor as defined in s. 403.541 that will not be interconnected” bill text, line 303 →
§ 6 Swaps nuclear energy in for renewable energy in plant-need reviews majors. 403.519

AIDeciding whether Florida needs any proposed new power plant, the commission must now weigh whether nuclear energy resources are being used to the extent reasonably available, in place of the prior factor asking about renewable energy sources and technologies.

“whether nuclear energy resources as well as conservation measures, are used to the extent reasonably available”
§ 7 Redefines clean energy to include nuclear power moderates. 366.92

AIThe renewable energy policy statute is renamed the clean energy policy statute, and its definition of clean energy now expressly includes energy produced by nuclear reactors alongside renewable energy and renewable natural gas.

“includes energy produced by nuclear reactors and includes renewable energy and renewable natural gas as those terms are defined in s. 366.91” bill text, line 224 →
§ 8 Drops rural cooperatives from the clean-energy standards duty moderates. 366.92

AIThe duty to develop and annually report clean-energy promotion standards no longer names rural electric cooperatives, while the same duty is broadened from municipal electric utilities to electric utilities generally.

“Each municipal electric utility and rural electric cooperative shall develop standards for the promotion, encouragement, and expansion of the use of renewable energy resources” bill text, line 232 →
