Abstract

Telah dilakukan penelitian mengenai analisis distribusi dosis radiasi foton berdasarkan variasi kedalaman dan luas lapangan penyinaran pada fantom menggunakan pesawat Linac tipe Clinac CX. Pengukuran distribusi dosis radiasi dilakukan untuk menganalisis distribusi dosis radiasi foton pada tiap kedalaman dan luas lapangan penyinaran agar dosis pada target dan organ kritis dapat dilihat dan mendapatkan dosis yang optimal berdasarkan  kurva isodosis. Kurva isodosis dibuat menggunakan data Percentage Depth Dose (PDD) dan profile dose (PD) pada berkas foton 6 MV dan 10 MV pada  kedalaman 5 cm, 10 cm, 15 cm, 20 cm, 25 cm, 30 cm dan luas lapangan penyinaran 10x10 cm2, 15x15 cm2, 20x20 cm2, 25x25 cm2, 30x30 cm2, 35x35 cm2, 40x40 cm2. Metode yang digunakan dalam pengolahan data PDD dan PD menggunakan teknik interpolasi linear supaya memiliki interval yang sama yaitu 0,25, kemudian menggunakan teknik pembobotan untuk menghitung dosis radiasi di tiap titik menggunakan Matlab. Kurva PDD menunjukkan bahwa persentase dosis radiasi dipengaruhi oleh kedalaman dan  tidak dipengaruhi oleh luas lapangan penyinaran terhadap  nilai  dosis radiasi. Kurva isodosis yang terbentuk dipengaruhi oleh kedalaman, luas lapangan penyinaran dan energi radiasi. Semakin bertambah kedalaman, semakin menurun persentase dosis radiasi dan semakin datar kurva yang dihasilkan. Dosis radiasi meningkat seiring dengan meningkatnya ukuran luas lapangan penyinaran

Abstract

One of the important reactor safety parameters to study is the issue of shutdown margin (SDM). This study aims to obtain an effective safety design of the NuScale reactor in reviewing the SDM value parameter. SDM calculations are performed using OpenMC, which is a programming code based on the Monte Carlo method. OpenMC is an open source calculation code that has the advantage of access to modifications to the reactor core geometry design. The type of reactor used in this simulation is the NuScale Small Modular Reactor (SMR) which is a Pressurized Water Reactor (PWR) type of reactor. The NuScale core simulation was designed in accordance with the General Design Criterion (GDC), which is a core arrangement that has a Control Rod Assemblies (CRA) regulating bank (RB) and CRA shutdown bank (SB) and UO2 fuel with an enrichment of <4.9%. From the calculation results, the SDM value of NuScale is 17743 pcm. This NuScale core SDM value indicates that the NuScale reactor under study complied with the sufficient safety design limits for all power levels and operating modes.
