Pengoperasian suatu pembangkit listrik tenaga nuklir secara selamat dan ekonomis sangat tergantung kepada ketersediaan material struktur yang handal. Selama umur operasi reaktor yang dewasa ini mencapai 60 tahun, material struktur terpapar temperatur yang tinggi, lingkungan korosif dan medan radiasi kuat yang terjadi akibat proses fisi. Struktur penopang bahan bakar akan memiliki umur lebih singkat dalam lingkungan demikian. Sementara itu tuntutan dalam pengembangan reaktor maju masa depan adalah temperatur operasi dan burnup yang lebih tinggi untuk meningkatkan efisiensi operasi reaktor. Material yang mampu mengatasi kondisi itu harus stabil secara dimensional dalam medan radiasi, baik dengan maupun tanpa adanya stress, serta memiliki sifat yang baik di lingkungan yang korosif. Makalah ini menelaah secara singkat litbang material struktur reaktor yang potensial digunakan dalam sistem reaktor maju, seperti baja ferritic/martensitic, baja ODS, dan keramik, termasuk sintesis baja ODS yang dikembangkan di BATAN. Selain itu dikaji pula kerusakan radiasi pada material struktur serta sintesis dan simulasi kinerja perisai radiasi menggunakan paket program MCNP5. Hasil kajian menunjukkan bahwa walaupun hasil yang ada sudah cukup baik, masih diperlukan litbang lebih lanjut guna mendapatkan material yang memenuhi kriteria yang diinginkan, baik melalui eksperimen maupun secara simulasi dan pemodelan dengan komputer.","PeriodicalId":179965,"journal":{"name":"Jurnal Pengembangan Energi Nuklir","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125130451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nilai jarak aman (Screening Distance Value, SDV) untuk tiap-tiap jenis sumber bahaya harus ditentukan menggunakan pendekatan konservatif sehingga pengaruh kejadian interaksi yang berada di luar jarak ini tidak perlu diperhitungkan lebih lanjut. Dari pengamatan, sumber tidak bergerak yang paling banyak berada di sekitar tapak adalah Stasiun Pengisian Bahan Bakar Umum (SPBU) dan Stasiun Pengangkutan dan Pengisian Bulk Elpiji (SPPBE). Oleh karena itu, penelitian ini bertujuan untuk menentukan SDV dari SPBU dan SPPBE untuk skenario ledakan dan kebakaran dengan lokasi studi di sekitar tapak Reaktor Daya Eksperimental (RDE), Puspiptek Serpong. Studi ini menggunkan Areal Location Of Hazardous Atmospheres (ALOHA) untuk mensimulasikan zona ancaman ledakan dan kebakaran dari substansi Bensin dan LPG. Simulasi ini melibatkan ledakan dan kebakaran iso-oktana di SPBU dan butane di SPPBE untuk menganalisis zona ancaman dari skenario kecelakaan. Diketahui bahwa SDV sangat tergantung dari jenis, maupun kapasitas material berbahaya, skenario kecelakaan serta kondisi atmosfer pada sumber bahaya tersebut. Dari penelitian ini, diketahui pula suatu sumber bahaya bisa mempunyai SDV lebih dari satu nilai. SDV SPBU berkapasitas 170.000 liter untuk skenario kebakaran 976 m dan 1.200 m, sedangkan untuk skenario ledakan adalah 958 m dan 1.200 m. SDV SPPBE berkapasitas 25.000 kg untuk skenario kebakaran 445 m dan 565 m, sedangkan untuk skenario ledakan adalah 430 m dan 573 m. Sementara SDV SPPBE berkapasitas 100.000 kg untuk skenario kebakaran 913 m dan 1.100 m, sedangkan untuk skenario ledakan adalah 758 m dan 1.100 m. Studi ini dapat memberikan alternatif penentuan nilai SDV pada studi dan evaluasi tapak reaktor nuklir.","PeriodicalId":179965,"journal":{"name":"Jurnal Pengembangan Energi Nuklir","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130021950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the study is to assess the conceptual design for the decay chamber of N16 nuclide in the primary cooling system of the reactor. In this design, the hold-up system decays the nuclide of N16 resulted from neutron activation product.

LPG station is a stationary source, which is one aspect of the external human induced events that need to be analyzed in the preparation of site evaluation reports to obtain site permits. Hazard potential that may occur from the depot LPG are fire, explosion and dispersion of hazardous and toxic gas. The release of LPG due to valve leakage which is then dispersed at a certain dose has potentially harmful to health, even death to the population around the RDE site.

In FTA, criticality analysis is performed to identify the weakest paths in the system designs and components. For this purpose, an importance measure approach can be applied. Risk managers can apply information obtained from this analysis to improve safety by implementing risk reduction measure into the new design or build a more innovative design. Various importance measure approaches have been developed and proposed for criticality analysis in FTA. Each important measure approach offers specific purposes and advantages but has limitations. Therefore, it is necessary to understand characteristics of each approach in order to select the most appropriate approach to reach the purpose of the study. The objective of this study is to review the current implementations of importance measure approaches to rank individual basic events and/or minimal cut sets regarding their contributions to the unreliability or unavailability of NPP safety systems. This study classified importance measure approaches into two groups, i.e. probability–based importance measure approaches and fuzzy–based importance measure approaches. This study concluded that clear understanding of the purpose of the study, the type of reliability data at hands, and the uncertainty in the calculation need to be considered prior to the selection of the appropriate importance measure approach to the study of interest.

Component reliability analysis is required in the aging management of RSG-GAS that has reached an age of 30 years. One of the required analyses is the assessment of the distribution of repair data and the estimation of related parameters. The Primary Purification System (KBE01) and the Purification and Warm Water Layer System (KBE02) are important components of RSG-GAS. By knowing the repair data distribution, the parameters of the most frequently occurring component repair and the average of the repair period can be estimated, so that the required provision of spare parts for the smooth operation of the reactor can be predicted. The purpose of this study is to analyze the components of the KBE01 and KBE02 systems through the data distribution approach using the matching test method. With the matching test, the form of data distribution can be determined, so the parameter of the average component repair period that can be used as a comparison of the maintenance period of the components can be estimated. The repair times of KBE01 and KBE02 in RSG-GAS on Core 52 through Core 88 (2006-2015) were analyzed using goodness-of-fit test. The repair times of AA068 and AP001 KBE01 follow the exponential distribution with average repair times of 631.6 and 451.2 days, respectively.

Industrial growth affects the increasing demand for electricity in various places, this also occurs on the island of Bangka. So far, electricity supply has only been obtained from fossil fuel power plants with inadequate capacity, unstable flow and depending on fuel supplies from outside the island. For this reason, it is necessary to build a Nuclear Power Plant (PLTN) which is believed to be reliable and able to overcome these problems. In order to prepare a safe and economical nuclear power plant site, influential parameters such as population density, cooling system, land clearing, cut and fill, and granite for the foundation have been analyzed. The novelty of this analysis lies in 2 methods which gradually used before come up with a final decision, namely spatial analysis and pairwise comparison using Geographic Information Systems (GIS) and Analytical Hierarchy Process (AHP), respectively. The scope of study area is based on the site vicinity (1:5.000) scale, located in the districts of West and South Bangka. The siting process refers to the rules set by the International Atomic Energy Agency (IAEA).
