Determining the weight value of safety indicator for nuclear installation in Indonesia using analytic hierarchy process

Abstract

BAPETEN, as a regulatory body for nuclear energy utilization in Indonesia, requires an indicator to evaluate the safety and security of nuclear installations. BAPETEN has made BAPETEN Regulation Number 1 Year 2017 concerning the Implementation of Inspections in the Supervision of Nuclear Energy Utilization which regulates the implementation of inspections and also mentions the use of safety and security indicators (SSI). SSI is an indicator of compliance of safety and security requirements used by BAPETEN to assess the performance of nuclear installations in Indonesia. Indicators that indicate the safeguard and security level of nuclear installations consist of two aspects, namely safeguard and additional protocol aspect and also the security aspect. Indicators that indicate the safety level of nuclear installations consist of 6 aspects, namely operation aspects, maintenance and ageing management aspects, radiation protection aspects, environmental management and monitoring aspects, nuclear emergency preparedness aspects, and management system aspects. Although each of these aspects will contribute to the level of nuclear installations safety and security, each of these aspects may have different weight values. BAPETEN Regulation Number 1 Year 2017 has determined weight values for safeguard and security aspects. However, the weight value for the safety aspect has not been determined in this regulation. Hence, this paper proposes the Analytic Hierarchy Process (AHP) method to determine the weight value of each aspect of nuclear installation safety indicators. The results of the study show that the AHP method can be used to determine the weight value of each aspect of the safety indicators of nuclear installations to be used by BAPETEN in assessing the performance of nuclear installation in Indonesia.
