There are presently 44 commercial heavy-water reac-tors (HWRs) operating or under construction in six coun-tries. For a number of years these HWRs have been world leaders in the achievement of high annual and lifetime ca-pacity factors and have …

Heavy water reactors (HWRs) are thermal reactors moderated by heavy water that can use heavy water, light water, carbon dioxide, and organic matter as coolants. Due to the small thermal neutron absorption cross-section of heavy water, natural uranium fuel can be used.

1999年8月1日 · HDR/HWR power plants burn no fuels, reinject their effluent and emit few greenhouse gases. It appears that HDR/HWR technology development should be pursued if only for these two major advantages, i.e., nearly inexhaustible …

1999年8月1日 · The idea of hot wet rock (HWR) (Takahaghi and Hashida, 1992) reservoirs proposed by Tohoku University, in which natural fluids are present in amounts insufficient to permit energy production at commercial rates, filled …

LISTING OF HALDEN REACTOR PROJECT REPORTS FOR 2015–2017Enclosure 2

The TWG-HWR is a group of experts that provides advice and support for programme implementation, reflecting a global network of excellence and expertise in the area of advanced technologies for Heavy Water Reactors (HWRs)1.

2017年7月25日 · Yet another object of the invention is to provide a rig where the HWR (snubbing unit) will be installed permanently in one rig centre inside the Rig Structure, installed on a separate...

2005年9月15日 · In addition to data on the fission product release behaviour of commercial SBR MOX and UO {sub 2} fuel, the IFA-633.1 experiment is providing data on thermal performance, fuel densification, fuel swelling and pellet cracking and relocation.

2010年7月31日 · In this paper, the changes of (S / V) ratio and diffusion coefficient of fission gas in UO 2 and MOX fuel pellets are analyzed based on the results of the irradiation tests using gas-flow rigs in the Halden Heavy Water Reactor (HBWR) in Norway, and the effect of fuel type and burnup on the changes are investigated.

1998年2月1日 · On-line measurements of radioactive fission product release have been performed in the gas-flow rigs in the Halden Reactor since 1980. There have been six gas flow rigs, IFA 430 sponsored by USNRC/EGetG, IFAs 504 and 563 sponsored by the Joint Programme, IFAs 558 and 569 sponsored by the UK/CEGB and EPRI/NFIR respectively and IFA 601 sponsored ...
