Expert system applications in support of system diagnostics and prognostics at EBR-II

Description: Expert systems have been developed to aid in the monitoring and diagnostics of the Experimental Breeder Reactor-II (EBR-II) at the Idaho National Engineering Laboratory (INEL) in Idaho Falls, Idaho. Systems have been developed for failed fuel surveillance and diagnostics and reactor coolant pump monitoring and diagnostics. A third project is being done jointly by ANL-W and EG G Idaho to develop a transient analysis system to enhance overall plant diagnostic and prognostic capability. The failed… more

Kinetics of Treat Used as a Test Reactor

Description: An analysis is presented concerning the reactor kinetics of TREAT used as a pulsed, engineering test reactor for fast reactor fuel element studies. A description of the reactor performance is given for a wide range of conditions associated with its use as a test reactor. Supplemental information on meltdown experimentation is included. (J.R.D.)

Neutron irradiation and compatibility testing of Li/sub 2/O

Description: A study was made of the neutron-irradiation behavior of /sup 6/Li-enriched Li/sub 2/O material in EBR-II. In addition, a stress-corrosion study was performed ex-reactor to test compatibility of Li/sub 2/O materials with a variety of stainless steels. Results of the irradiation testing showed that tritium and helium retention in the Li/sub 2/O (approx. 89% dense) lessened with neutron exposure. Helium and tritium retention appear to approach steady-state after approx. 1% /sup 6/Li burnup. The st… more

Design and operating experience of EBR-II intermediate heat exchanger

Description: Experimental Breeder Reactor II (EBR-II) has operated for over 15 years at the Idaho National Engineering Laboratory near Idaho Falls. EBR-II has served the nation in providing information on fuels, materials, and components under conditions approaching those expected for commercial power plants. In addition, EBR-II is a power plant generating electricity with an availability of about 70%. A key component, the Intermediate Heat Exchanger (IHX), of any Liquid Metal Fast Breeder Reactor (LMFBR) m… more

Off-normal performance of EBR-II (Experimental Breeder Reactor) driver fuel

Description: The off-normal performance of EBR-II Mark-II driver fuel has been more than satisfactory as demonstrated by robust reliability under repeated transient overpower and undercooled loss-of-flow tests, by benign run-beyond-cladding-breach behavior, and by forgiving response to fabrication defects including lack of bond. Test results have verified that the metallic driver fuel is very tolerant of off-normal events. This behavior has allowed EBR-II to operate in a combined steady-state and transient … more

Experience with EBR-II (Experimental Breeder Reactor) driver fuel

Description: The exceptional performance of Experimental Breeder Reactor-II (EBR-II) metallic driver fuel has been demonstrated by the irradiation of a large number of elements under steady-state, transient overpower, and loss-of-flow conditions. High burnup with high reliability has been achieved by a close coupling of element design and materials selection. Quantification of reliability has allowed full utilization of element lifetime. Improved design and duct materials currently under test are expected t… more

Safety and operating experience at EBR-II: lessons for the future

Description: EBR-II is a small LMFBR power plant that has performed safely and reliably for 16 years. Much has been learned from operating it to facilitate the design, licensing, and operation of large commercial LMFBR power plants in the US. EBR-II has been found relatively easy to keep in conformity with evolving safety requirements, largely because of inherent safety features of the plant. Such features reduce dependence on active safety systems to protect against accidents. EBR-II has experienced a numb… more

Transient performance of EBR-II driver fuel

Description: The first phases of qualification of the EBR-II driver fuel for repeated transient overpower operation have recently been completed. The accomplishments include prediction of the transient fuel and cladding performance through ex-core testing and fuel-element modeling studies, localized in-core power testing during steady-state operation, and whole-core multiple transient testing. The metallic driver fuel successfully survived 56 transients, spaced over a 45-day period, with power increases of … more

Computer programs for describing the dynamic behavior of EBR-II

Description: Kinetic studies are performed at EBR-II to ensure that the dynamic characteristics of the reactor indicate integrity of the system and surrounding environment. These studies are done by analysis of power perturbations caused by a drop rod and a rod oscillator. The power perturbation following a rod drop is first analyzed by inverse-kinetics procedures to obtain a time-dependent reactivity. This reactivity is further fitted to a feedback transfer fanction characteristic of linear differential eq… more

Evaluation of ex-reactor loading event on high-fluence EBR-II control-rod thimble 5E3

Description: A Type 304 stainless steel EBR-II control-rod thimble (CRT 5E3) with high fluence was damaged while undergoing dimensional evaluation. The damage, which occurred when the thimble was inadvertently loaded in a bending mode, consisted of rather localized but extensive fracture. An elastic stress analysis of the bending mode was done on the thimble, using semimembrane shell theory. The analysis disclosed several important aspects that the simpler and more commonly employed techniques do not disclo… more
