A self-purging fuel element for a gas-cooled nuclear reactor comprises an elongated coolant gas-permeable body 36 having one or more fuelcontaining chambers 34, a bore 32 extending through the body 36, and a restriction 38 within the bore 32, the chambers 34 being in fluid communication with...
The quantification of plutonium (Pu) in spent nuclear fuel is an increasingly important safeguards issue. There exists an estimated worldwide 980 metric tons of Pu in the nuclear fuel cycle and the majority is in spent nuclear fuel waiting for long term storage or fuel reprocessing. This study...
The thinking behind all this autophagous engineering is that most of the weight of a rocket consists of the propellants needed to lift the rocket itself and the payload off the ground. In addition, more fuel is needed to lift the fuel needed to lift the rocket, payload, and fuel, and m...
This work shows that Compton-suppressed selfinduced XRF can be effectively applied to Pu accounting in spent nuclear fuel.doi:10.3938/jkps.71.543Park, Se-HwanJo, Kwang HoLee, Seung KyuSeo, HeeLee, ChaehunWon, Byung-HeeAhn, Seong-Kyu

fuel on-line to ensure that the burnup limit is not breached. The potential exists for using a relative burnup indicator, which would allow the use of a relative self-calibrating approach for efficiency determination. The utilization of several fission products as built-in on-line relative ...
One end of a long cylindrical flat-ended fuel element to be inserted endwise into a fuel channel in a reactor has an axial boss at one end to engage with a mating part on the next element to align them axially. Pref. the boss is tapered. It may be a solid blunt cone or may be ...
Under discussion are such major aspects of the nuclear energy sector as cost effectiveness, nuclear and environmental safety of reactors and nuclear fuel cycle facilities, sustained fuel supply, and proven feasibility of a proliferation-resistant technology. These requirements can be met, for instance,...
technology in Korea has been acquired through four stepwise nuclear fuel technology development phases starting from the 1970s that may include a fuel import phase, a turnkey fuel technology transfer phase, a fuel technology joint-development phase and a self-sufficient fuel technology development ...
