In this study Modified CANDLE burn-up scheme was implemented to create small and long life fast reactors with natural Uranium as fuel cycle input. Such system can utilize natural Uranium resources efficiently without the necessity of enrichment plant or reprocessing plant. The core with metallic fuel based was subdivided into 10 regions with the same volume. The fresh Natural Uranium is initially put in region-1, after one cycle of 10 years of burn-up it is shifted to region-2 and the each region-1 is filled by fresh Natural Uranium fuel. This concept is basically applied to all axial regions. The reactor discharge burn-up is 31.8% HM. From the neutronic point of view, this design is in compliance with good performance.

Pengembangan program PLTN harus didasarkan pada komitmen untuk menggunakan tenaga nuklir hanya untuk tujuan damai, dengan cara yang aman dan selamat, yang mengharuskan adanya infrastruktur nasional yang berkelanjutan yang melibatkan berbagai aspek, seperti kerangka peraturan perundangundangan. Kerangka tersebut berkaitan dengan pembentukan badan regulator independen dan penyusunan peraturan tentang nuklir, yaitu proteksi radiasi, bahan radioaktif dan sumber radiasi, keamanan instalasi nuklir, kesiapsiagaan kedaruratan dan tindakan tanggap darurat, penambangan dan pengolahan, transportasi, limbah radioaktif dan bahan bakar bekas, pertanggungjawaban kerugian nuklir dan kompensasi, proteksi, kontrol ekspor dan impor, dan proteksi fisik, sesuai konvensi dan standar internasional. Untuk itu, pemerintah telah menerbitkan berbagai peraturan perundang-undangan di bidang nuklir guna menjamin keamanan dan keselamatan pekerja, masyarakat maupun lingkungan hidup dari bahaya radiasi yang mungkin timbul.

The reactors utilizes UN-PUN as fuel, helium as coolant, and can be operated without refueling for 10 years in each batch. Reactor design optimization is performed to utilize natural uranium as fuel cycle input. This reactor subdivided into 10 regions with equal volume in radial directions. The natural uranium is initially put in region 1, and after one cycle of 10 years of burnup it is shifted to region 2 and the region 1 is filled by fresh natural uranium fuel. This concept is basically applied to all regions. To achieve criticality requirement relatively high fuel volume fraction is applied. In this study several parametric survey were performed for several parameters such as fuel-to-coolant volume fraction ratio, core radius, and core height. After some optimization process we determine a standard core with a height and a diameter of 350 cm and 240 cm respectively, and the volume fraction for this design is 65% fuel, 10% cladding and 25% coolant. Calculation has been done by using SRAC-Citation system code and JENDL-3.2 library.
