Reaktor Daya Eksperimental (RDE) is an experimental power reactor based on HTGR technology that implements inherent safety system. Its safety systems are in compliance with “defense in depth” philosophy. RDE is also equipped with reactor cavity cooling system (RCCS) used to remove the heat transferred from the reactor vessel to the containment structure. The RCCS is designed to fulfil this role by maintain the reactor vessel under the maximum allowable temperature during normal operation and protecting the containment structure in the event of failure of all passive cooling systems. The performance and reliability of the RCCS, therefore, are considered as critical factors in determining maximum design power level related to heat removal. RCCS for RDE will use a novel shape to efficiently remove the heat released from the RPV through thermal radiation and natural convection. This paper discusses the calculation of RCCS thermal analysis during accident. The RPV temperature must be maintained below 65ºC. The accident is assumed that there is no electricity from diesel generator supplied to the blower. The methodology used is based on the calculation of mathematical model of the RCCS in the passive mode. The heat is released through cavity by natural convection, in which the RCCS is capable to withdraw the heat at the rate of 50.54 kW per hour.Keywords: Passive safety, RCCS, RDE, Thermal analysis

The acceleration of national development, especially in the industrial sector, requires an adequate national energy supply. There are various types of energy sources which include conventional energy sources as well as new and renewable energy sources including nuclear energy. The problem is how to utilize these energy sources into energy that is ready to be utilized. BATAN as a research and development institution in the nuclear field has taken the initiative to contribute to the development of technology for providing electricity and other thermal energy, particularly reactor technology as a power plant and a provider of thermal energy. This research aims to analyze the design of the IPWR type SMR reactor cogeneration energy conversion system. The IPWR reactor cogeneration energy conversion system which also functions as a reactor coolant is arranged in an indirect cycle configuration or Rankine cycle. Between the primary cooling system and the secondary cooling system is mediated by a heat exchanger which also functions as a steam generator. The analysis was carried out using ChemCAD computer software to study the temperature characteristics and performance parameters of the IPWR reactor cogeneration energy conversion system. The simulation results show that the temperature of saturated steam coming out of the steam generating unit is around 505.17 K. Saturated steam is obtained in the reactor power range between 40 MWth to 100 MWth. The results of the calculation of the energy utilization factor (EUF) show that the IPWR cogeneration configuration can increase the value of the energy utilization factor up to 91.20%.

AnalYsis On AlMg2 AS RSG-GAS CLADDING material corrosion IN CHLORIDE CONTAINING WATER. The AlMg2is one of an alluminium alloy that used as cladding material for the RSG GA. Siwabessy (RSG-GAS) research reactor in Serpong, Indonesia. The reactor uses demineralized water as primary coolant with 6.5 to 7.5 of pH. A poor treatment of water in primary coolant can lead to the problem of AlMg2 integrity. The primary coolant concentration of chloride must lower than 0.0094 ppm to protect cladding corrosion. The purpose of this study is to determine the effect of temperature and chloride ion concentration to AlMg2. The method in this research is to observe the corrosion rate for AlMg2 material by using Potentiostat. The laboratory experiments were conducted in various temperatures (28, 35, 40 and 45°C) and concentration of sodium chloride of 0.005, 0.010, 0.015, 0.020, 0.025, 0.030 and 0.035 ppm. The results show the corrosion rates were very small, and the highest corrosion rate occurred is 1.23 x 10-3mpy in 0.035 ppm of NaCl at 45°C .

TEMPERATURE DEPENDENCE OF PRIMARY SPECIES G(VALUES) FORMED FROM RADIOLYSIS OF WATER BY INTERACTION OF TRITIUM β-PARTICLES. G(values) are important to understand the effect of radiolysis of Nuclear Power Plant (NPP) cooling water. Since direct measurements are difficult, hence modeling and computer simulation were carried out to predict radiation chemistry in and around reactor core. G(values) are required to calculate the radiation chemistry. Monte Carlo simulations were used to calculate the G(values) of primary species , H•, H2, •OH dan H2O2 formed from the radiolysis of tritium β low energy electron. These radiolytic products can degrade the reactor components and cause corrosion under the reactor operating conditions. G(values) prediction can indirectly contribute to maintain the material reliability. G(values) were calculated at 10-8, 10-7, 10-6 and 10-5 s after ionization at temperature ranges. The calculation were compared with the G(values) of g-ray 60Co. The work aimed to understand temperature effect on the water radiolysis mechanism by the tritium β electron. The results show that the trend similarity was found on the temperature dependence of G(values) of tritium β electron and g-ray 60Co. For tritium β electron, G(values) for free radical were lower than g-ray 60Co, but higher for molecular products as temperature raise at 10-8 and 10-7. The significant differences for these two type of radiations were on G(H2), G(•OH) and G(H•) at 10-6and 10-5 s above 200 oC.

Keloids are skin disorders or benign tumours that are due to abnormal wound healing in the binding tissue after a trauma, inflammation, surgical wounds, or burns. Low activity radioisotopes have shown to be effective in curing or eliminating keloids on the skin. One of these radioisotopes is phosphorus-32 (32P), a beta (β-) emitter with a half-life of 14.3 days. This radioisotope can also be developed for the treatment of keloid and skin tumours. Currently, keloid is treated by a conventional method e.g.by applying the bulk of 32P radioisotope directly on keloid area. However, this method is considered inefficient and less secure. The purpose of this research is to obtain a technology for preparing of 32P-labeled skin patch. The first step of this research is to produce 32P-labeled chromic phosphate (Cr32PO4) colloids, through condensation involving oxidation-reduction reaction. In this step, Cr (VI) is reduced to Cr (III) to form Cr32PO4 with particle size of <1 μm. These particles (Cr32PO4) are to expect to distribute evenly when mixed with silicon to form skin patch which will not decompose easily. Characterization of the prepared Cr32PO4colloids gave a yield of 97,8% with particle size of greater than > 1μm. Further study needs to be performed in due time in order to have Cr32PO4 colloids with a suitable particle size.Key words: keloid, chromic phosphate colloid, skin patch, condensation, oxidation-reduction reaction

Hingga saat ini radioisotop tehnesium-99m (99mTc) masih banyak digunakan di bidang kedokteran nuklir di seluruh dunia. Hal ini karena 99mTc memiliki waktu paro 6 jam dan memancarkan gamma murni pada energi 140 keV sehingga merupakan radioisotop yang ideal untuk diagnosis. 99mTc dapat dihasilkan salah satunya dari generator 99Mo/99mTc. Prototipe generator 99Mo/99mTc dibuat dengan menggunakan Molibdenum-98 (98Mo) alam hasil iradiasi neutron, yang dilengkapi dengan kolom berisi material berbasis zirkonium (MBZ) dan kolom alumina. Penentuan performa prototipe generator dilakukan dengan menentukan yield 99mTc, kualitas larutan natrium pertehnetat (Na99mTcO4) yang dihasilkan, dan laju dosis pada permukaan prototipe generator. Yield 99mTc dari prototipe generator yaitu 76,95 ± 7,7%. Prototipe generator menghasilkan radioisotop 99mTc (Na99mTcO4) dengan karakterisitik yang memenuhi persyaratan US Pharmacopoeia, yaitu larutan jernih, memiliki pH 6 ± 0,6, kemurnian radionuklida (lolosan 99Mo) sebesar 0,022 μCi/mCi 99mTc, kemurnian radiokimia 99mTcO4- sebesar 99,85 ± 0,05%, kemurnian kimia (lolosan alumina) < 5 μg/mL, dan laju dosis permukaan prototipe sebesar 1,18 mSv/jam. Dengan demikian prototipe generator 99Mo/99mTc ini sudah menunjukkan performa yang baik dalam menghasilkan radioisotop 99mTc untuk keperluan medis dan memiliki laju dosis yang aman, namun perlu ditingkatkan kembali yieldnya.

Penelitian ini dilakukan dengan tujuan untuk mengetahui efektifitas peraturan perlindungan air tahan terhadap dampak pengembangan permukiman masalah apa yang terjadi dan pola perlindungan yang telah ada adapat dikembangkan. Tujuan penelitian ini untuk mengetahui apakah upaya perlindungan sember air bawah tanah terhadap dampak pengembangan permukiman di Kabupaten Sukoharjo merupakan masalah-masalah apa yang terjadi dalam pelaksanaan pembangunan pemukiman, upaya-upaya apakah yang dapat dilakukan untuk mengatasi masalah-masalah tersebut, dalam rangka mengembangkan pola perlindungan hukum yang lebih baik. Metode penelitian yang digunakan adalah deskriptif dengan pendekatan kualitatif abstrak indikatif. Pendekatan yang dilakukan adalah yuridis empirisatau yuridis sosiologis. Data yang digunakan meliputi data primer dan data sekunder. Penelitian dilakukan di Kabupaten Sukoharjo. Areal permukiman yang diteliti dipilih secara â€œpurposiveâ€. Responden penelitian dipilih secara â€œnon probabilityâ€. Responden diambil dari pengembang, masyarakat penghuni, aparat yang terkait. Data priper diperoleh dengan mempergunakan â€œcontent identificationâ€. Analisis data secara kualitatif yaitu dengan model analisis interaltif. Hasil penelitian yang dilakukan menghasilkan temuan bahwa pada pola perlindungan sumber air bawah tanah dari kerusakan sebagai dampak dari pengembangan permukiman di Kabupaten Sukoharjo sudah dapat memberi hasil yang efektif. Dair data penelitian ini karena pengembangan permukiman dilakukan tidak pada daerah tangkapan hujan, ruang terbuka yang tersedia. Luas lahan yang dikembangkan masih memenuhi persyaratan yaitu lebih dari 40% penggunaan sumber air tanah oleh penghuni permukiman masih sangat terbatas. Masalah-maslah yang ditemukan antara lain belum lengkap peraturan perundangan yang diperlukan, belum ada kelembagaan yang secara khusus menangani perijinan dan pengawasan, fasilitas jalan permukiman berupa aspal sehingga tidak memberi efek resapan air, koefisien dasar bangunan yang melebihi standart karena belum adanya fasilitas sumur resapan masih kurangnya pemahaman tentang pengaturan arti penting sumber air bawah tanah. Pola perlindungan yang perlu dikembangkan berupa penyusunan Peraturan Daerah yang mencakup perijinan tentang pembangunan permukiman baru dan perijinan penggunaan/eksploitasi air tanah. Disamping itu, diperlukan pembentukan suatu kelembagaan yang terintregasi yang melibatkan instansi teknis terkait lainnya di bidang perijinan dan pengawasan terhadap eksploitasi air tanah. Dari hasil pembahasan didapat saran berupa perlu dilakukan penelitian labih lanjut pada berbagai daerah lain untuk digunakan sebagai perbandingan dalam rangka merumuskan pola perlindungan hukum yang lebih tepat terhadap air tanah dari kerusakan akibat pengembangan permukiman.
