Development of the method (strategy, technology) for the remediation activity at the former uranium facility “Pridneprovskiy Chemical Plant''


The Production Corporation “Pridneprovskiy Chemical Plant” (PChP) was one of the largest facili-ties of the military complex of the Soviet Union, where production of uranium for the Soviet atomic programme was carried out starting in 1949. The plant is situated in a densely populated area in the industrial zone of Dniprodzerzhynsk City (250,000 inhabitants) and close to the Dniper River. The different legacy objects of the PChP site pose varying levels of risk to local populations and non-radiological workers on the site.
The overall objective of this project was to implement modern, effective methodologies and tools for planning remediation activity and to develop the method (a strategy, technology(ies)) for the remediation activity at the former uranium facility “Pridneprovskiy Chemical Plant" based on international best practice. The project seeks to characterize the risks associated with this facility, develop an overall remediation strategy for the site and conceptual remediation designs for selected priority objects.
The purposes of the project were as follows:

  • Compilation of an up-to-date inventory of tailings, buildings and site data describing radio-logical and chemical composition, physical condition (e.g. volume, area), etc.;
  • Development of recommendations regarding the application of best international practice to the planning and implementation of remediation activities at the former Uranium facilities at PChP site while, at the same time, considering the Ukrainian regulatory regime and readily available technologies;
  • Assessment of the radiological risk for non-radiological workers on site and the population around the site;
  • Development of a method (a strategy and technology (ies)) for the remediation activities at the PChP site; and
  • Development of the remediation plan and TEJ for remediation of selected facilities at the PChP site.

The project was comprised of the following tasks:

  • Task 1: Project Preparation and Inception Phase
  • Task 2: Analysis of the information and results of historical national and international inves-tigations at the PChP site
  • Task 3: Analysis of international remediation experience, practices, recommendations, and their application at the PChP site
  • Task 4: Analysis of current and future levels of safety and ranking of PChP objects
  • Task 5: A report on a remediation strategy for the PChP legacy site, remediation plan and feasibility study for selected facilities in support to the selection and implementation of remedial actions for the site
  • Task 6: Final report and dissemination of results
  • Task 7: Identification of strategies to reduce imminent risk at the site
  • Task 8: Raising awareness about the hazards and risks at the legacy site

Project Results
The primary results of the project include development and delivery of an overall remediation strategy for the PChP site, conducting additional characterization work to understand better the radiological situation at the site, identification and ranking of risks, conceptual remediation designs for a selected number of priority objects, calculation of doses to workers responsible for conducting the proposed remediation measures, identification of measures to mitigate imminent risks, and development of curricula to build capacity of the nuclear operator and provide information to public about the hazards present at the site and measures to mitigate this risk.
The situation at the PChP site presents a significant hazard to members of the public and workers on the site. Although there is still much work to be done (through characterization work and further risk assessments), it is clear that action needs to be taken to bring the situation under control. The regulator needs to establish operating licenses and controls for work conducted on the site (both by the nuclear operator and the privately owned enterprises) and the operator needs to work according to acceptable standards of radiation protection (including development of a radiation protection programme and continuous monitoring of the site and workers). Support should be provided by the international community to assist Ukraine in developing and implementing these capacities while urgently and safely moving forward in the planning and execution of the necessary remedial actions. The site should undergo the appropriate preparation for such actions by stabilization of the existing imminent risks and taking measures for managing radioactive waste resulting from any remedial actions.
Eight objects at the PChP site were selected for development of conceptual remediation designs and associated risk assessments. However, there are many other significant risks present at the PChP site. The next tier of priority objects should be taken forward for remediation planning and associated safety and risk assessments. Under conservative assumptions, the proposed remediation works at some objects lead to worker doses above Ukrainian regulatory limits. The specific recommendations are described in detail in the provided task and final report.
