Regulation of Uranium Mining, Tailings and Radiation Protection

No single treaty governs uranium mining. Rules come from international safety standards, tailings and waste instruments, and national licensing regimes that differ by country.

Key facts

  • IAEA Safety Standards are not binding on states by themselves, but countries use them as the basis of national regulation.
  • The Joint Convention on spent fuel and radioactive waste safety was adopted in 1997 and entered into force on 18 June 2001.
  • The Global Industry Standard on Tailings Management was launched on 5 August 2020 by UNEP, ICMM and PRI.
  • ICRP recommendations underpin the dose limits and optimisation principles used in most national radiation-protection law.
  • Licensing of a uranium mine normally covers environmental assessment, operation, closure and financial assurance.

Layers of rules: from recommendation to licence

Regulation of uranium mining and milling combines several layers:

  • Scientific bodies recommend protection principles.
  • International organisations turn these into safety standards.
  • Treaties and industry standards address specific risks such as waste and tailings.
  • National law and a licensing authority apply binding requirements to each operator.

The same mine usually falls under mining law, environmental law, radiation-protection law and water law. In many places it also falls under indigenous and land-rights law.

General mining and environmental rules apply to uranium mining as well as nuclear rules. The responsible agency may therefore be a nuclear regulator, an environment ministry, a mining authority or a shared arrangement. Country examples are given below.

ICRP recommendations and IAEA Safety Standards

ICRP recommendations

The International Commission on Radiological Protection (ICRP) is an independent body. Its recommendations, most recently consolidated in Publication 103 (2007), set out three principles:

  • justification;
  • optimisation of protection, meaning keeping exposures as low as reasonably achievable;
  • application of dose limits.

For planned exposure situations, ICRP recommends an occupational limit of 20 millisieverts per year, averaged over five years. It recommends a public limit of 1 millisievert per year. Background and units are explained on the radiation dose page.

IAEA Safety Standards

The International Atomic Energy Agency publishes its Safety Standards Series, with Fundamentals, Requirements and Guides. General Safety Requirements Part 3 is titled Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards. Several international organisations co-sponsor it, and it is the main reference for dose limits and exposure control.

Other IAEA documents address the safety of mining and processing of uranium and thorium ores, the management of radioactive waste and the remediation of contaminated sites. The IAEA standards are not binding unless a state adopts them or requests IAEA services that apply them.

The International Labour Organization also maintains instruments on radiation protection of workers. They complement the IAEA standards.

Waste, tailings and the Joint Convention

The Joint Convention

The Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management was adopted in Vienna on 5 September 1997. It entered into force on 18 June 2001. Its parties report on national practice and undergo peer review at periodic meetings.

Its scope covers spent fuel and radioactive waste from civilian programmes. Waste containing only naturally occurring radioactive material is generally outside its scope, unless a party declares it as radioactive waste. Uranium mill tailings are therefore mainly regulated nationally.

Tailings standards

For tailings structures as such, the principal non-governmental benchmark is the Global Industry Standard on Tailings Management (GISTM). The United Nations Environment Programme, the International Council on Mining and Metals and the Principles for Responsible Investment released it on 5 August 2020, after the Brumadinho dam failure. It applies to existing and future tailings facilities regardless of mineral.

ICMM member companies committed to bring facilities with extreme or very high potential consequences into conformance by August 2023, and all others by August 2025.

Causes and engineering aspects are covered on the tailings dam safety page, and surveillance on the monitoring page. The mill tailings page describes the characteristics of uranium tailings in particular.

National regulators and their remits

CountryMain bodiesNotes
United StatesNuclear Regulatory Commission (NRC); Agreement States; Environmental Protection Agency (EPA)The Uranium Mill Tailings Radiation Control Act of 1978 governs mill tailings; ISR facilities are licensed by the NRC or an Agreement State
CanadaCanadian Nuclear Safety Commission (CNSC)Licenses uranium mines and mills under the Nuclear Safety and Control Act; provincial bodies also have roles
AustraliaARPANSA for Commonwealth entities; state and territory authoritiesMine licensing is mainly state or territory responsibility
South AfricaNational Nuclear Regulator (NNR)Also covers radioactivity at mining sites
European UnionNational authorities under Euratom basic safety standardsMember states transpose Euratom directives into national law

Country pages describe specific regulators and facilities: the United States page, the Canada page and the South Africa page.

Licensing stages from exploration to closure

Procedures differ, but uranium projects generally pass through similar stages.

  1. Exploration: permits for drilling and land access, often with environmental conditions and consultation duties.
  2. Environmental and social impact assessment: baseline studies of water, air, radiation and communities, with public participation.
  3. Construction and operating licences: technical design review, radiation-protection programmes, waste and tailings management plans and emergency planning.
  4. Operation: monitoring, reporting, inspection and periodic licence renewal.
  5. Closure and post-closure: decommissioning, rehabilitation, long-term stewardship and release from regulatory control.

For in-situ leaching, groundwater restoration criteria receive extra attention (see the ISL page). The indigenous peoples page considers the rights of affected peoples.

Closure planning and financial assurance

Legacy sites in several countries show the cost of poor closure planning. Modern regimes therefore usually require a closure plan agreed before operations begin. They also usually require financial assurance, such as a bond, letter of credit or trust fund, which is reviewed periodically. The aim is that rehabilitation and long-term monitoring can be paid for even if the operator fails. Details differ widely: some jurisdictions require full coverage, others partial coverage with periodic reassessment.

Uranium tailings need long-term controls because radium-226 and thorium-230 persist for very long periods. This is why many regimes require engineered covers and institutional control. The US decommissioning page discusses closure of related facilities.

Frequently asked questions

Is there one international law for uranium mining?

No. International standards, such as IAEA Safety Standards and ICRP recommendations, guide national rules. Treaties such as the Joint Convention cover specific topics. National licensing sets the binding requirements.

What are the ICRP dose limits?

For planned exposure, ICRP Publication 103 recommends an occupational limit of 20 mSv per year averaged over five years. It recommends a public limit of 1 mSv per year. Both exclude natural background and medical exposure.

What is the GISTM?

The Global Industry Standard on Tailings Management was launched in August 2020 by UNEP, ICMM and PRI. It applies to tailings facilities of any mining sector and sets requirements from design to closure.

Who regulates uranium mining in Canada?

The Canadian Nuclear Safety Commission licenses uranium mines and mills. Provincial authorities also have roles under their own laws.

What is financial assurance?

It is money or a guarantee, such as a bond, held in advance. It pays for closure and long-term monitoring of a mine or mill even if the operator cannot.
