[Back-end management] Radioactive Waste disposal

인쇄

It is stipulated that radioactive wastes produced in nuclear power plants and other facilities be disposed of safely, according to relevant laws, in facilities appropriately designed and constructed depending on the concentration of radioactivity and its hazard levels. KEPCO E&C is taking an initiative in designing domestic radioactive waste disposal facilities by performing the A/E of the first-stage cave disposal facilities for low- and intermediate-level radioactive wastes that do not contain a high level of heat and radioactivity; the second-stage near-surface disposal facilities since 2014; and the third-stage landfill disposal facilities since 2021. In addition, we are at the forefront of designing spent fuel dry storage facilities - which temporarily store high - level radioactive spent fuel at nuclear power plant sites - determined to be installed at Hanbit Nuclear Power Plant sites in 2023.

Description

Design of cave disposal facilities for radioactive wastes

  • Cave disposal facilities are suitable for the disposal of low and intermediate-level radioactive wastes from nuclear power plants and industrial facilities. KEPCO E&C is the only company in Korea with a track record of designing cave disposal facilities for low and intermediate-level radioactive wastes.

Major track records

  • Preliminary designs of radioactive waste management facilities
  • Conceptual designs of radioactive waste disposal facilities
  • A/E of Low- and intermediate-level radioactive waste disposal facilities(Phase 1)

Design of near-surface disposal facilities for radioactive wastes

  • Near-surface disposal of radioactive wastes are suitable for low-level radio active wastes. KEPCO E&C is working on the design of the first domestic near-surface disposal facilities under construction in Gyeongju.

Major track records

  • Phase 2 preliminary designs of Low- and intermediate-level radioactive waste disposal facilities
  • Basic designs of phase 2 construction project for Wolsong LILW Disposal Center
  • Phase 2 A/E of Low- and intermediate-level radioactive waste disposal facilities(in progress)

Designs of landfill radioactive waste disposal facilities

  • The large quantities of very low-level radioactive wastes generated from the decommissioning of nuclear facilities including nuclear power plants must be disposed of to prevent the leakage of radioactive materials and the spread through underground and surface water, and other natural phenomena. To achieve this, landfill disposal facilities equipped with engineering barriers are utilized. KEPCO E&C is completely furnished with design technology for landfill disposal facilities and currently carrying out related projects.

Major track records

  • Preliminary designs of radioactive waste management facilities
  • Conceptual designs of radioactive waste disposal facilities
  • A follow-up phase site survey for disposal facilities
  • Phase 3 basic and detailed designs of landfill disposal facilities(in progress)

Design of spent nuclear fuel dry storage facility

  • Spent nuclear fuel generated from nuclear power plants must be taken out of the site before decommissioning and stored safely in temporary or interim storage facilities until it is disposed of. KEPCO E&C is capable of designing storage facilities that can store spent nuclear fuel safely against all the disastors possible.

Major track records

  • Conceptual designs of interim storage facilities for spent fuel(2012)
  • Preliminary feasibility study of storage facilities for light water reactor spent fuel(2016-2019)
  • Planning for spent fuel transport/storage standardization(2016-2019)
  • A/E of dry storage facilities for spent fuel at Kori headquarters(In progress)
  • A/E of dry storage facilities for spent fuel at Hanbit headquarters(In progress)

Design of an independent storage pool for spent nuclear fuel

  • This technology is about remodeling the spent fuel storage system of nuclear power plants into an independent system used exclusively for spent fuel storage during the decommissioning phase and operating them, ensuring safe management of spent fuel during the decommissioning phase, smooth decommissioning, and the reduction of the management cost before decommissioning. KEPCO E&C posesses a patent on the design of an independent spent fuel storage tank.

Major track records

  • A project for the expansion of storage capacity of storage tank for heavy and light water reactors(1995-2010)
