    The TRIGA PUSPATI Reactor (RTP) is a nuclear research reactor with 1 MW thermal energy in Malaysia. RTP was commissioned after gaining first criticality on June 28, 1982. The word TRIGA stands for T-Training, R-Research, I-Isotope production and GA-General Atomic Inc. (a supplier of TRIGA-type nuclear reactors based in the United States). Meanwhile, PUSPATI is an abbreviation of the Tun Ismail Atomic Research Center (the second name used by Malaysian Nuclear Agency from 8 October 1973 to 17 June 1983).

    RTP is a pool-type research reactor, with the core located at the bottom of a seven-meter deep aluminum tank and surrounded by a biological shield based on high-density concrete. The solid fuel reactors use enriched uranium and zirconium-hydride (U-ZrH1.6). Distillation water serves as a neutron coolant and moderator, while graphite serves as a neutron reflector.

    RTP applications are generally divided into three activities, namely research, irradiation and education and training.


    Main research activities currently carried out are divided into three categories:

    1. Safe operation of RTP and enhance its utilization;
    2. Ageing management program on RTP structures, systems and components (SSC); and
    3. Safety, security and safeguard of RTP.


    RTPs are designed to use neutron sources in the field of nuclear, science and engineering (NSE).

    Facilities offered for irradiation are:

    1. Rotary Rack
    2. Pneumatic Transfer System
    3. Central Thimble
    4. Neutron Beams
    5. Thermal Column
