The article provides the results of developing the Draft Regulatory Guide for Application and Justification of Risk-Informed Maintenance. Its provisions will be used as supplementary to requirements of regulatory document NP 306.2.217‑2017 Requirements for Making Risk-Informed Decisions on Safety of Nuclear Power Plants and it will be applied together with the requirements of other regulatory guidelines for the implementation and application of risk-informed approaches to the operational activities of Ukrainian nuclear power plants (NPPs). Implementation of the risk-informed approaches for maintenance optimization at pilot NPP Unit of Ukraine revealed the need to develop additional regulatory guidelines to support regulatory activities. The developed Draft Regulatory Guide takes into account current scientific and technical approaches to the implementation and application of the risk-informed approaches to optimize maintenance of NPP safety systems based on international experience, taking into account the law and regulations of Ukraine. This Regulatory Guide contains recommendations for the nuclear and radiation safety state review (technical assessment) of the licensee’s documents for justification and application of risk-informed approaches to optimize maintenance of safety systems at Ukrainian NPPs. SNRIU officials and representatives of the technical support organization (SSTC NRS) will use this Regulatory Guide for state review (technical assessment) after its approval according to the established procedure by SNRIU and implementation.
