Abstract

Sintilator plastik dengan detektor photomultiplier silikon multisaluran (SiPM) merupakan kemajuan inovatif dalam teknologi deteksi radiasi. Teknologi ini memadukan efisiensi sintilator plastik dengan sensitivitas dan keserbagunaan SiPM multisaluran, sehingga menawarkan solusi canggih untuk berbagai aplikasi. Pada tabung pengganda tradisional, terdapat keterbatasan terkait dimensi yang besar, daya tahan yang rentan, memerlukan tegangan tinggi dan sensitivitas yang masih rendah, sehingga desain detektor ini mengatasi keterbatasan tabung pengganda foto tradisional tersebut. Sifat sistem yang kompak dan modular membuatnya cocok untuk lingkungan yang beragam, memfasilitasi integrasinya ke dalam pengaturan eksperimental atau perangkat pemantauan radiasi portabel. Pengembangan detektor ini diuji secara eksperimental dengan berbagai variasi sumber dan titik dan hasil evaluasi menunjukkan detektor yang dirancang dapat mendeteksi sinar beta dari 36Cl dan 90Sr, serta dapat melokalisasi sumber titik.

Abstract

Accident Tolerant Fuels (ATFs) represent a significant advancement in nuclear safety, offering the potential to mitigate the risks associated with nuclear reactor accidents. This paper provides a comprehensive overview of the development and current state of ATF technology, tracing its evolution and highlighting key technological milestones. Through an analysis of various case studies, we examine the practical application and performance of ATFs in real-world scenarios. Despite the promising capabilities of ATFs, their development and deployment are not without challenges. We delve into the technical, regulatory, and economic hurdles that must be overcome to realize the full potential of ATFs. Looking ahead, we explore the prospects of ATFs, discussing potential advancements and their implications for the nuclear industry. The findings of this paper underscore the transformative role of ATFs in enhancing nuclear reactor safety and charting a new horizon in nuclear technology.

Abstract

The High-Temperature Gas-Cooled Reactor (HTGR), a promising candidate for Generation IV nuclear reactors, boasts superior inherent passive safety features and a continuous fuel handling system. This system employs multi-pass cycles, utilizing pneumatic and gravitational mechanisms to feed, circulate, and unload the pebble bed fuel element. This paper presents a descriptive analysis assessing the safety risk of the fuel handling system design in HTR-10. The Hazard and Operability Study (HAZOP) methodology is employed to identify hazard parameters, deviation limitations, causes, impacts, and potential risks to the system’s main components. The establishment of probability scales, consequence criteria, risk level ratings, and control activities adheres to the ISO 31000 standard. Primary data were gathered through expert interviews, while secondary data were sourced from design layout documentation, literature reviews, and safety analysis reports. Six main components - the elevator, core, singulator, failed fuel separator, burnup measurement, and distributor - were selected as assessment nodes from the piping and instrumentation diagram. The assessment revealed that each node initially presented a moderate to extreme risk potential (risk level rating C to E). However, after applying the effectiveness index of the designed control, the residual risk for all nodes was reduced to an acceptable limit (risk rating A - very low). Therefore, the fuel handling system design already incorporates adequate control activities to mitigate potential safety risks due to system component failure. As safety risk assessment is dynamic, it should be reviewed periodically or whenever there are design changes at any project stage. This ensures the safety risk magnitude is consistently known and managed effectively.

Abstract

This paper presents a novel detector design for radiation detection technology, based on pixelated plastic scintillators coupled to multi-channel silicon photomultipliers (SiPMs). This detector combines the efficiency of plastic scintillators with the sensitivity and versatility of SiPMs, Overcoming the limitations of traditional photomultiplier tubes in terms of durability, power consumption, and sensitivity. The compact and modular nature of the detector makes it suitable for diverse environments and applications, such as portable radiation monitoring devices or integration into existing experimental setups. The performance of the detector was evaluated using beta-ray sources of 36Cl and 90Sr, and it was demonstrated that the detector can detect and localize the point source with high accuracy and resolution.
