Bill
AB 2647
Sets up labor standards for advanced nuclear projects and requires a 2027 CEC assessment on in-state advanced reactors’ role in California’s 100% zero-carbon goal.
Executive overview:
AB 2647 seeks to (1) create a framework for advancing advanced nuclear technologies in California, (2) modify siting and permitting constraints for advanced nuclear reactors, and (3) require the California Energy Commission (CEC) to prepare a comprehensive assessment by July 1, 2027 on the potential role of advanced nuclear technologies and in-state nuclear powerplants to meet future electricity needs and align with the state’s 100% zero-carbon electricity target by 2045.
Key objectives:
- Enable advanced nuclear reactors to potentially be exempt from existing prohibitions on siting new nuclear fission powerplants, subject to labor and workforce safeguards.
- Establish a robust, public, and technically informed assessment of advanced nuclear options to support critical California infrastructure and long-term resource planning.
- Encourage collaboration among major state bodies (Energy Commission, Public Utilities Commission, Independent System Operator, etc.) to evaluate nuclear energy’s role in a low-carbon grid.
Main provisions and changes:
1) Labor standards and skilled workforce requirement (Section 25524.3)
- Defines “advanced nuclear reactor” and related terms (apprenticeable occupations, skilled and trained workforce, etc.).
- Before declaring an advanced nuclear reactor not subject to Sections 25524.1/25524.2, the Energy Commission must verify a legally enforceable commitment to use a skilled and trained workforce for on-site work (construction, alteration, installation, repair, maintenance) within apprenticeable building and construction trades.
- If approved, the owner/operator/developer must ensure compliance with these labor standards for certified projects.
- Requires monthly reporting to the Labor Commissioner including worker details (apprenticeship program, location, graduation date). Reports are public records.
- Establishes penalties for noncompliance: up to $5,000 per month for first violations, up to $10,000 per month for subsequent offenses within three years (subject to adjustments/waivers for proportionality). Civil penalties are enforceable, with process for appeals. Project labor agreements can exempt this requirement if they include arbitration enforcement.
2) Comprehensive assessment by the Energy Commission (Sections 25524.1, 25524.2, and new 25524.3)
- AB 2647 adds a requirement for the Energy Commission to prepare, by July 1, 2027, a comprehensive assessment of:
- The potential role of advanced nuclear technologies in supporting California’s critical infrastructure.
- The potential for new in-state nuclear powerplants to cost-effectively meet statewide electricity needs.
- Alignment with the state’s policy to achieve 100% zero-carbon electricity by 2045.
- The assessment should consider system costs, reliability, emissions, deployment timelines, waste management and disposal pathways (including advanced fuel cycle tech), environmental and public health impacts, and siting considerations.
- The assessment should evaluate the use of high-renewable, dispatchable zero-carbon resources to complement renewables, and compare costs and benefits across different energy pathways.
- It should analyze spent fuel management costs (onsite, interim, long-term) relative to other technologies.
- It should examine workforce implications, including the use of a skilled and trained workforce in construction and operation, and potential post-2045 procurement needs for nuclear electricity.
- The Commission shall consult with the Public Utilities Commission (PUC), ISO, and other agencies, hold workshops, and solicit broad stakeholder input (academic experts, potential developers, labor, ratepayer advocates, environmentalists, etc.).
- The commission may update the initial assessment as appropriate.
- Agencies may evaluate nuclear energy for long-term resource needs notwithstanding siting prohibitions in Sections 25524.1 and 25524.2.
3) Contextual and procedural framing
- The bill reaffirms the Energy Commission’s jurisdiction over certifying thermal powerplants of 50 MW or more, but adds allowances to consider advanced reactors and to require labor standards compliance for those projects.
- It preserves certain exceptions from the current prohibition for specific existing facilities (Diablo Canyon Units 1–2 and San Onofre Units 2–3) and outlines conditions under which a nuclear fission plant requiring fuel rod reprocessing may proceed (if applicable), including legislative review timelines for findings.
- It directs the Commission to coordinate with PUC, ISO, and other public agencies, and to consider environmental and public health impacts when evaluating nuclear options.
Impact and who is affected:
- Nuclear project developers and operators: Must demonstrate compliance with labor standards if seeking exemptions or certification for advanced reactors; face monthly Labor Commissioner reporting and potential civil penalties for noncompliance.
- Labor and apprenticeship programs: New enforcement and reporting requirements tied to advanced nuclear construction and maintenance.
- Energy policymakers and regulators (CEC, PUC, ISO): Directed to conduct joint assessments, workshops, and coordinated evaluations of long-term nuclear energy roles.
- California ratepayers and taxpayers: Implicitly affected through long-term cost and environmental implications of integrating advanced nuclear options into the energy mix; assessment aims to inform future policy and investment decisions.
- Public and environmental health: Provisions emphasize labor safety and public health considerations in deployment of advanced nuclear technology.
Timeline:
- July 1, 2027: CEC to complete the comprehensive assessment (as part of the integrated energy policy report or separately, as determined).
- Ongoing: Stakeholder workshops; potential updates to the assessment as appropriate.
Notes:
- The bill reflects an intent to diversify California’s clean-energy portfolio with advanced nuclear options while embedding labor standards and rigorous analytical review.
- As amended, AB 2647 does not create immediate authorization for new in-state nuclear plants; it triggers a formal assessment and sets conditions for potential future approvals.
