A system requirement analysis for developing an information system in the review and assessment process in P2STFRZR (Pusat Pengkajian Sistem dan Teknologi Pengawasan Fasilitas Radiasi dan Zat Radioaktif) has been conducted. The need for this type of software development was based on the recommendation on the effectivity survey held in the previous year. The results of the survey recommended developing an information system to provide systematic and trackable progress in the review and assessment process as well as a repository for the report in P2STPFRZR. By having the information system, the performance of P2STPFRZR, and the effectivity of the review and assessment is expected to improve. The system requirement analysis highlights the function representing the real-life process of review and assessment. In real life, the result of review and assessment is used as the basis for decision making by the licensing division in the regulatory body. The systematic process with clear communication needed to be considered and included in the system requirement analysis. Only the initial phase of the waterfall modeling method is used in this paper. The analysis results have been transferred into the use case diagram showing the intended function by the user in the system and what the system can do in the future. The result is intended to be the trigger for system design by the responsible party in BAPETEN. [ABSTRACT FROM AUTHOR]

The progress and development of information technology has opened up one form of nuclear crime, namely computer crime. The Stuxnet incident that occurred in 2010 is one example of cyber incidents related to nuclear security. The International Atomic Energy Agency (IAEA) as an international regulatory body has paid attention to computer security as outlined in one of the important elements in NSS 20 - Objective and Essentials Elements of a State's Nuclear Security Regime. The security aspect itself is one of the aspects emphasized in Act Number 10 of 1997 concerning Nuclear Energy. Government Regulation Number 54 of 2012 concerning Nuclear Installation Safety and Security outlines a more detailed discussion of nuclear installation security, which is a more specific discussion on safety in the aspect of physical protection regulated in Regulation of the Head of the Nuclear Power Supervisory Agency Number 1 of 2009 concerning Installation Physical Protection Systems and Nuclear Materials. However, all of these regulations still do not explicitly mention computer security. This paper was prepared to provide recommendations that can be used in the preparation of regulations and guidelines related to computer security in nuclear installations. This paper was prepared using the main reference NSS 17 - Computer Security at Nuclear Facilities which was perfected by the review of Regulatory Guide 5.71 - Cyber Security Programs for Nuclear Facility, CSA N290.7-14 - Cyber Security for Nuclear Power Plants and Small Reactor Facilities, and REGDOC-2.5.2. - Design of Reactor Facilities: Nuclear Power Plants. From the results of the study, it was concluded that several things that need to be considered as required regarding computer security are the establishment of a computer security team, the preparation of a computer security plan, a graded approach to computer security, and risk assessment.

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.

Interventional cardiology and radiology workers are exposed with occupational radiation. Radiation workers must use not only personal dosimeter; but also eye lens dosimeter in order to maintain the dose that does not exceed the dose limit value set by Nuclear Energy Regulatory Agency (Bapeten) which is 20 mSv a year with no single year exceeding 50 mSv. In order to provide a reliable with affordable price dosimeter, a new eye lens dosimeter was developed at NuklindoLab using TLD-900 (CaSO4:Dy) disc for measurement of dose in term of Hp(3). The type testing including homogeneity test, linearity of dose response, angular dependence test, and determining detection threshold were done after the irradiation carried out in Secondary Standard Dosimetry Laboratory (SSDL) Agensi Nuklear Malaysia. The method of the irradiation was based on ISO 4037-3 and the reference of the type testing was based on ISO 12794. The coefficient of variance (CV) value from homogeneity test results 4.8%, the linearity test result R2 values vary from 0.998 to 0.999, the angular dependence result ranges from 0% to 19% with average value 12.9%, and the detection threshold of SOCA dosimeter value was 0.35 mSv.
