ith the arrival of the 115th U.S. Congress, the House of Representatives began hearings on the Nuclear Waste Policy Amendments Act of 2017. The legislation restarts Yucca Mountain as a repository for highly radioactive waste. In 1987, Congress amended the Nuclear Waste Policy Act of 1982, selecting Yucca Mountain, Nevada, as the only site to be studied, expecting the repository to open in 1998....

reading-rm/doc-collections/ (ACRS & ACNW Mtg schedules/agendas). Videoteleconferencing service is available for observing open sessions of ACRS meetings. Those wishing to use this service for observing ACRS meetings should contact Mr. Theron Brown, ACRS Audio Visual Technician (301–415–8066), between 7:30 a.m. and 3:45 p.m., e.t., at least 10 days before the meeting to ensure the availability o...

In order to use gaseous fuels in Diesel Engines, Dual-Fuel Diesel Engine (D. F. D. E) the pilot injection approach is chosen. To predict its performance, an engine cycle model, based on limited-pressure Diesel cycle, is constructed. The model predicts D. F. D. E performance with LPG, and CNG gases. Comparing with pure Diesel engine, by increasing gas proportion in dual-fuel, indicated power and...

previously approved by OMB and assigned OMB Number 0581–0177. Reporting and recordkeeping burdens are necessary for compliance purposes and for developing statistical data for maintenance of the program. The forms require information which is readily available from handler records and which can be provided without data processing equipment or trained statistical staff. As with other, similar ma...

An objective of the Advanced Fuel Cycle Initiative in the United States is to develop technologies for transmutation of transuranic elements currently in spent light water reactor fuel. The advantages of fast-spectrum reactors, including accelerator-driven systems, are recognised. Because low-to-zero conversion-ratio designs are desired, fuels with little or no fertile uranium are required. Bas...

The development of techniques for the accurate quantification of the plutonium content in spent nuclear fuel would provide significant advances for shipper/receiver differences and for input accountability at reprocessing facilities. Several techniques have been studied previously for achieving this goal but these have met with limited success. Due to the radioactive nature of spent fuel, decay...

In Japan, R&D activities for partitioning and transmutation (P&T) have been promoted under the OMEGA programme for more than 15 years. These activities were reviewed by the Atomic Energy Commission in Japan in 2000. In accordance with the results of the review, three institutes, the Japan Atomic Energy Research Institute (JAERI), the Japan Nuclear Cycle Development Institute (JNC) and the Centr...

After the Chernobyl accident, a National Emergency Plan of protective measures for radiological emergencies has been set up in Italy to cope with nuclear risks which require actions at national level. Since the Italian nuclear power plants are, at present, not operational, the most relevant nuclear risk source identified in the National Emergency Plan is related to an accident occurring in a nu...
