[en] A 100 kW low power reactor (LPR) will be updated to a rating power of 5000 kW to enlarge its service ability. The problems concerning physics, thermohydraulics, the reactor block and reactor building, coolling systems, and other auxiliary systems are summaried. The devices and facilities used for production and rearch works are described

[en] In the design of ionization chamber cable lifting mechanism, follow-up problem has to be solved considering the limit space at top of the reactor. In comparison with various follow-up technic, a cramping method is eventually adopted, in which the interval between cramps and cramp number have been able to meet the requirements of the ionization chamber lift

[en] The main parameters, equipment and features of the 5 MW LPR are briefly introduced. The main feature is the utilization of discharged fuel element by HFETR. Failure detection system has been set up for monitoring of each fuel element. Neutron transmutation doping of monocrystal silicon, production of Mo-Tc isotope, and topaz irradiation are main tasks of this reactor
