[en] The commissioning of 5 MW Low Power Reactor is introduced in three aspects, working out of the commissioning document, performance of the commissioning, and some important tested results. The commissioning results show that the measured data completely meet the requirements of design, and the reactor is operable

[en] It is proved by theory analysis and some tests relative to inherent safety that the 5 MW LPR (Low Power Reactor) has favourable inherent safety. When loss-of-pump power accident take place and the reactor scrammed simultaneously, the reactor safety can be ensured, and the decay heat is removed out of the reactor core only by natural circulation

[en] The performance of 80 and 60 fuel assemblies cores for High Flux Engineering Test Reactor (HFETR) has been compared with theoretical analysis and operating results. These results show that the core performance of 80 fuel assemblies is the same as that of 60 fuel assemblies in the following aspects: the permission power of core, the irradiation test of materials, the transmutation doping of single crystalline silicon, the production of Mo-Tc isotopes, etc. The core of 80 fuel assemblies is more convenient in operation after 500 kw test loop installed, and in greatly raising the production of ⁶⁰Co source with high specific radioactivity and the usage of fuel. As compared to the production of ⁶⁰Co source of 60 fuel assemblies core, the benefit of 80 fuel assemblies core can increase more than 3.8 millions RMB yuan per year. (2 refs., 2 tabs.)
