The department objective is to provide scientific and technical support to the State Nuclear Regulatory Committee of Ukraine in its regulatory activity on decommissioning of radiation hazardous facilities, transformation of the Shelter into an environmentally safe system, management of nuclear materials and radioactive waste.

Main activities and tasks

• Identification of safety – develop regulatory criteria and requirements;
• Safety assessment — develop methodologies and carry out expert reviews;
• Coordination of the related safety assessments — health and safety, ecological, fire, technical, etc.;
• Regulatory oversight — develop methodologies for inspections and support inspections;
• Safety analysis — develop analytical materials.

These activities and tasks cover the following facilities:

• The Shelter: from the sarcophagus to a new safe confinement and dismantling;
• NPPs and facilities with radiation technologies: from final shutdown, preservation up to dismantling and “green field” state;
• Radioactive waste management facilities: from radioactive waste generation to its final disposal;
• Facilities for management of nuclear fuel and nuclear materials: from handling operations to long-term storage.

Main outputs

Brief information on the main department outputs for 2004-2009 is stated below.

Rule-making activity

Scientific and technical support in developing regulations:

Regulatory and legal acts (RLA) developed by the department in 2004-2009:

• Review of RLA “General Safety Provisions on Decommissioning of Nuclear Power Plants and Research Reactors”
• Development of RLA “Requirements for Siting and Location of Radioactive Waste Disposal Facility”
• Development of RLA “Classification Criteria and Main Technical Requirements for Structures, Systems and Elements Designed for Radioactive Waste Management Depending on their Classification According to Their Impact on Safety”
• Development of RLA “Procedure of the State Supervision of Observing Nuclear and Radiation Safety Requirements for Nuclear Energy Use”
• Development of RLA “Procedure for NPP Power Units Commissioning”
• Development of RLA “Authorizing Procedure for Activities or Operations at the Stages of Nuclear Installation Commissioning, Operation and Decommissioning”

Expert activity

In 2004-2009 the department developed about 200 reviews and technical assessments of NRS.

The most essential are:

• Reviews and technical assessments on the Shelter Implementation Plan (SIP) (OU. Documents) concerning:
  • New safe confinement (NSC)
  • Stabilization of the Shelter confinement structure
  • Integrated automated monitoring system (IAMS) of the Shelter
  • Shelter physical protection system
  • Shelter modernized dust suppression system (MDSS)
  • Shelter fire protection systems
  • External engineering communications and auxiliary buildings at the Shelter
  • Operational radiation monitoring systems of the Shelter personnel
  • Shelter integrated data base
  • Management of fuel containing materials (FCM) and other radioactive waste
• Shelter safety status
• Reviews and technical assessments on spent nuclear fuel (SNF) and radioactive waste safe management. Documents concerning:
  • Safety of Chornobyl NPP (ChNPP) power unit No 1 systems and components related to SNF storage and radioactive waste management
  • Safety of the existing spent fuel storage facility SFSF-1 at ChNPP
  • Integrated management of radioactive waste at ChNPP
  • Safety of engineered near surface disposal facilities for solid radioactive waste (ENSDF)
  • Substantiation of restructuring special complexes for radioactive waste management
  • Technical specifications for solid radioactive waste management complexes at Rivne and Zaporizhzhya NPP
  • Safety or uranium facilities
• Reviews on decommissioning. Documents concerning:
  • Chornobyl NPP decommissioning programs
  • Decommissioning concepts of Zaporizhzhya, Rivne, Khmelnytsky and South Ukrainian NPPs
  • Decommissioning programs of research WWR-M reactor of the Nuclear Research Institute at the National Academy of Sciences of Ukraine

Methodological support of reviews

SIP documents review methodology

A package of methodologies for review (technical assessment) of SIP documents was developed to provide methodological support to ensure high-quality reviews (technical assessment). In total, 13 methodologies were developed.

Review methodology for decommissioning documents

The methodological document “Guideline for Reviewing NPPs Decommissioning Documents of the Operational Organization (Assessment Package)” was developed.

Inspection support

A package of inspection procedures for different SIP activities has been developed to provide methodological support to the state supervision of the safe implementation of SIP. In total, 13 inspection procedures were developed.

Analytical materials for inspecting the status and safety of the Shelter activities within SIP are prepared at regular intervals resulting from the package of inspection procedures in SIP implementation.

SNRCU conducts such inspections at regular intervals. SSTC experts participate in the inspections at SSE ChNPP as advisors.

International scientific and technical cooperation

Shelter activities were carried out under project SIP -02-3-001 “Scientific and Technical Support in SIP Safety Regulation”

General objective of the project is to provide scientific and technical support to the SNRCU and other regulatory bodies of Ukraine in regulatory activity on SIP implementation at the Shelter to achieve SIP safety objectives and ensure personnel safety during SIP implementation.

The main task of the project is to assess SIP documents submitted to the SNRCU and other regulatory bodies for completeness and compliance with safety requirements in the SIP projects and tasks. The results of safety reviews (technical assessments) are the basis to make regulatory decisions regarding SIP projects and tasks by SNRCU and other regulatory bodies of Ukraine.

RLA “Procedure for the State Supervision on Observing Nuclear and Radiation Safety Requirements in Nuclear Energy Use”, “Procedure for NPP Power Units Commissioning” and “Authorizing Procedure for Activities or Operations at the Stages of Nuclear Facility Commissioning, Operation and Decommissioning” are developed within Task 1 of “Revision of Inspection Procedures for Commissioning of New Nuclear Facilities” of project TACIS U3IA/03-3 (UK/TS/32) “Development of Regulations and Inspection Procedures for Commissioning of New Nuclear Facilities”.

Technical specifications for solid radioactive waste management complexes at Rivne and Zaporizhzhya NPP were reviewed within Task 2 of “Support to the State Nuclear Regulatory Committee of Ukraine in Licensing Industrial Project (U1.01/04) – Solid Radioactive Waste Management at Rivne NPP” of project TACIS U3IA/03-3 (UK/TS/32).

Documentation on the facilities necessary for ChNPP decommissioning was reviewed within project TACIS U3.01/04 (UK/TS/35) “Support to the State Nuclear Regulatory Committee of Ukraine in Licensing Activities related to TACIS/NSA Financed Decommissioning Facilities at Chernobyl NPP-site Assistance Projects – Follow-up of UK/TS/26”.

Coordination of SIP regulatory activities

Activities of expert organizations (EO) and other regulatory bodies (RB) are coordinated at the stage of “early” involvement into consideration of design documentation and in reviewing the documents which are not considered by the State Enterprise “Ukrinvestexpertyza”.

This coordination covers: involvement of EO on contractual basis into consideration of licensing documents (LD); determination of endorsed approaches to assess LD, work schedules; receiving EO comments on LD, their summarization and submission to ChNPP; arrangement of meetings to discuss LD; receiving the consideration results of LD and appropriate regulatory decisions; submission of complete package of documents with the LD regulatory review results to SNRCU.

Now there is a significant positive experience of the coordinated activity of RD and their EO in reviewing several SIP projects. Under coordination of SSTC NRS EO of different regulatory bodies considered the materials and unsolved issues arose during development of SIP projects. These projects were developed as those that generally meet safety requirements. State reviews of the completed projects were carried out in quite short terms.

The experience demonstrated that the efficient system for coordinated activity of both RB and EO was developed.
