Abstract

The development of cancer in the world is very high. According to the World Health Organization (WHO) 1.69 million people die from cancer per year in the world, while the cases of cancer in Indonesia are also not much different. Some areas have a high prevalence of cancer, namely D.I Yogyakarta. Cancer has become a scourge for many people. There are many treatments available, such as chemotherapy, surgery, and radiation. Additionally, there is radiotherapy using neutron capture of boron-10 with energy 0.025 Ev. This treatment does not damage other tissue because the resulting particles such as He-4 and Lithium-7 have ranges that are a distance of 4.5-10 μm, so that the deposited energy is limited to the diameter of a single cell. The treatment is called Boron Neutron Capture Therapy (BNCT). There are several BNCT facilities such as a reactor, radial piercing beam port, thermal column, and shielding. The function of shielding is to absorb the neutron and alpha radiation. The shielding is made using paraffin material that is excellent in absorbing neutron radiation. In addition to paraffin there are also other materials, such as lead, used as paraffin casing. In a shielding simulation using MCNPX software, the resulting dose rate of radiation exposure outside of the BNCT facility in vitro and vivo tests is equal to 6.5 μSv / h. The thickness of the shielding paraffin used is 40 cm, Pb casing 25 cm, and 5 cm soft tissue.

Abstract

Boron Neutron Capture Therapy (BNCT) is a radiotherapy method that utilizes the interaction of boron-10 and thermal neutrons that produce lithium particles and alpha particles to kill cancer cells. Before treatment is done to humans, clinical and non-clinical testing is carried out. Non-clinical testing included In Vivo and In Vitro tests. This In Vivo and In Vitro test involves the Kartini reactor as a source and guarantees that the workers and the environment are safe when the reactor is operated. This research is aimed to analyze the neutron radiation after it has passed shielding made from paraffin with aluminum casing in an in vivo/ in vitro testing facility for BNCT. The shielding should withstand neutron radiation so that the radiation dose does not exceed the dose constraint set by PSTA-BATAN at 10 μSv/ hour. In this research, the initial shielding design was in the form of a 2D beam arrangement. For this reason, optimization of each shielding beam form into 3D can be identified. After that, the shieldings were produced and arranged in the radial piercing beamport of Kartini Reactor. The measurement results showed that neutron radiation exposure in the working area around shielding at all measurement points is 0 μSv/ hour , so the results of shielding design calculations can be validated. Neutron radiation exposure was found at 3.78 μSv/ hour and 2.36 μSv/ hour in measurements that were taken between the shielding gaps on the left and right side of the reactor's wall. These measurement results were below the prescribed dose constraint, so the working environment is safe.

Abstract

Hardness testing is used to investigate the hardness of metallic material. Hardness tests are performed frequently because it is simple, inexpensive, and other mechanical properties can be estimated from hardness such as tensile strength. The basic concept of hardness testing is pressing a hard point or round ball against surface material. The Brinell hardness is used in this experiment. The Brinell hardness number is determined fpom the diameter of indentation. This study will investigate the hardness number of aluminium shielding of wax Paraffin, three sample specimens of aluminium plate with dimensions of 5x5 cm and thickness of 3 mm. The result from the test is 30.89 BHN

Abstract

Abstract The Kartini Reactor has been operated up to 100 kilo watts. There are two types of nuclear fuel used in the Kartini Reactor, type 104 and type 204. Currently the nuclear fuel utilization license granted by BAPETEN allows 77 pieces, consisting of 73 type 104 and four type 204. Based on Kartini Reactor fuel utilization report, there are 71 pieces of nuclear fuel in the reactor core, consist of 69 type 104 and two pieces of type 204. There are four pieces of type 104 in the bulk shielding. The control rod categorizations are divided into regulating rod, shim rod and safety rod. Regarding the operation license renewal of Kartini Reactor, we conducted an assessment of various aspects related to the safety of the reactor. One of the aspects we conducted was regards to the neutronic. On the initial phase of the neutronic aspect study, a simulation was performed using the SCALE computer code. This study will only evaluate the relation between the bank of the control rod position to the effect of criticality in the Kartini Reactor. The results showed that fully up criticality has a value of 1.02173 ± 0.00018, and fully down criticality has value of 0.96026 ±0.00021. The reactor reaches criticality when the position of the control rod is at an altitude of 42.85135 cm.

Abstract

Energy and the environment are major topics of concern throughout the world nowadays. Consumption of fossil fuels is still the dominance to meet energy needs. The adverse effects of the consumption of fossil fuels on the environment and humans are priorities in determining policies. Many countries in the world have begun restructuring their energy mix and exploring the potential of new and renewable energy (NRE). Indonesia is currently in a stage of economic development where the demand for energy consumption is extremly high. The availability of fossil fuel energy is decreasing and is expected to run out in the next 42 years. In addition, environmental pollution due to the use of fossil fuels continues to increase. The application of NRE technologies and better efficiency in energy’s use could help decrease dependence on fossil fuels. One of the energy’s commodities that warrants attention is wind energy. However, the development of wind power plants in Indonesia has many barriers. The low level of trust in wind availability and the high investment costs are the main barriers to its development. The current capacity of wind energy power plants in Indonesia installed is 1.96 MW, whereas the total amount of wind energy available in Indonesia is 970MW. Wind power plants produce less carbon. This makes wind power one of the solutions to have environmentally friendly power plants. This assessment aims to increase awareness for planning for the future with the collaboration of conventional energy and NRE as clean technology to save the world from global warming.

Abstract

BNCT is the latest method in nuclear technology that combines chemotherapy and radiotherapy. Therapy that uses ionizing radiation must pay attention to the safety of patients, radiation workers and the environment. Therefore, shielding is needed for radiation protection, especially gamma radiation. A refining for the shielding and the testing had been done to know the limitation for the use of testing facility in vivo / in vitro that meets the NPD/Dose Constraint limitation from PSTA BATAN with parameter shielding radiation outcome, shielding geometry, and energy value Kartini Reactor. The highest measurement result reaches 4.8 mSv/j with 100kW energy. By considering the measurement result with the NPD/Dose Constraint limitation from PSTA BATAN for Kartini Reactor operation, the activity of testing facility in vivo/in vitro can be done 46 times in a year. Keywords : BNCT, Shielding, Gamma Radiation.

Abstract

Indonesia needs to provide a large enough source of energy for development purposes, not only to produce and distribute daily necessities, but also to build industries that improve the nation's competitiveness and the lives of the people. With so many people, Indonesia has the largest energy consumption of any country in the Southeast Asia region and is fifth in the Asia Pacific in primary energy consumption, after the countries of China, India, Japan and South Korea are expected to increasingly encourage Indonesia's energy needs in the future. In Indonesia the main energy source is the fossil fuel, a non-renewable energy source. With the large amount of energy demands in Indonesia, the use of fossil fuels as energy-generating materials is increasing, which results in the depletion of fuel. Besides that, use of fossil fuels in Indonesia produces carbon dioxide in the wild which can endanger the natural environment. From the problems that occur in Indonesia with the limitations and constraints in conventional energy sources, it has been found that the Nuclear Power Plant (NPP) is a viable alternative for providing electricity. The construction of the NPP would spur national industry development because various industries could be involved in the construction of nuclear power plants. One type of nuclear power plant, namely the Boiling Water Reactor (BWR) has already been implemented in several countries with some success and has advantages that could be applied in Indonesia. It is expected that the presence of nuclear power plants in Indonesia would reduce the use of fossil fuels and increase clean and renewable energy in Indonesia.
