Chemical permit granted to Hanhikivi 1 nuclear power plant

The Finnish Safety and Chemicals Agency (Tukes) has issued a chemical permit for the handling and storage of large amounts of hazardous chemicals required at the Hanhikivi 1 nuclear power plant. The appeal period has begun.

The permit concerns the large-scale storage and use of chemicals during the operation of the Hanhikivi 1 nuclear power plant. Hazardous chemicals are stored and used at the nuclear power plant, among other things, in the management of water chemistry, in cleaning processes, in the cooling of the generator and as fuel for the backup generators. Radioactive substances are excluded from the scope of the chemical safety legislation, so radiation safety is not considered in the permit process. Radiation safety is supervised by the Finnish Radiation and Nuclear Safety Authority (STUK).

The chemical permit decision contains a total of 12 terms and conditions concerning:

  • the quantity of hazardous chemicals that can be stored on the company's premises,
  • storage of chemicals and the design, testing and manufacture of the chemical tanks,
  • storage of fuel oil and diesel,
  • fire protection of storage, transfer, handling and operating equipment for flammable liquids,
  • the design, risk assessment and construction of pipelines for hazardous chemicals,
  • taking into account the results of the of the chemical accident fire modeling prepared for the nuclear power plant in the location and design of the permanent structures of the plant,
  • safe exit from rooms with chemical storage tanks in accident situations,
  • updating the explosion protection document once more detailed plans are completed,
  • the appointment at least one chemicals operation supervisor for the power plant,
  • training of workers on the properties, safe handling and operation of hazardous chemicals used at the plant and what to do in the event of an accident,
  • regular drills about operating in the event of a chemical accident and
  • the safety notice to the general public before the commissioning of the plant.

The appeal period concerning the permit decision has begun. The decision document is available for public viewing until 14th of February at the Tampere office of the Finnish Safety and Chemicals Agency (address Yliopistonkatu 38, Tampere, Finland) and on the Tukes website (in Finnish) >>.
