چکیده

Abstract Simulation of the new exposure room shielding for Neutron Radiography Imaging (NURI) at 1 MW PUSPATI TRIGA MARK II (RTP) nuclear research reactor in Malaysian Nuclear Agency, Malaysia has been presented this article. Previous to be disassembled due various reasons such as radiation streaming problem and outdated since was constructed 1985. The NURI facility had undergoing major upgrading all their instrument including beam collimator, imaging system, sample positioning, instrumentation shielding, shielding. This paper aims simulate dose rate mapping using Monte Carlo simulation code MCNPX. design consists several modular blocks built from ordinary concrete Ferro boron concrete. is used enhance performance facility. Results showed that containing manage reduce by 1150 % critical area compared average around during operation power ranging μSv/hr - 10 μSv/hr.

TRIGA Mark-II Research Reactor

The present work gives a methodology for assessing radiological concentration of I, I, I, I, and I due to a hypothetical accident of TRIGA Mark-II research Reactor at AERE, Savar, Bangladesh. The concentrations were estimated through different pathways like ingestion of vegetation, milk, and meat from air and ground deposition. The maximum air concentrations for all 16 directions were found at ...
