India has entered in the field of spent fuel reprocessing as early as sixties by way of R&D studies and finalising the process flow sheet. India's first spent fuel reprocessing plant was commissioned in the year 1965 at Trombay to reprocess spent fuel arising from research reactors. The recovered plutonium is being utilised to feed various programmes of the department. With the passage of time,...

A heavy load drop into the spent fuel pool, or onto the spent fuel pool wall, can affect the structural integrity of the spent fuel pool. A loss-of-inventory from the spent fuel pool could occur as a result of a heavy load drop. The staff evaluated heavy loads as Generic Technical Activity A-36, which resulted in the publication of NUREG-0612 [Ref. 1]. Cask handling is expected to be the domina...

There are 103 commercial nuclear power stations currently operating in the United States, generating a total of about 2 000 t of spent fuel each year. Over 40 000 t of spent fuel have accumulated since these plants began operation, with the fuel being stored first in at-reactor spent fuel storage pools and later in independent spent fuel storage installations and dry cask storage facilities. Th...

Thermochemcial characteristics of powder fabricated using oxidation treatment of spent PWR fuel and SIMFUEL were evaluated for recycling of spent fuel such as DUPIC process. Especially, the influence of spent fuel burn-ups on the powder fabrication characteristics was experimentally evaluated, ranging from 27,300 to 65,000 MWd/tU. Densities of powder manufactured from an oxidation, OREOX and th...

Previous Advanced Fuel Cycle Initiative (AFCI) studies were made to assess the effects of the existing accumulation of LWR spent fuel in the United States on the capability to partition/transmute actinides using existing and advanced LWRs. The concept of treating the “oldest fuel first” indicated that significant advantages could be gained in both partitioning, transmutation, and in overall cos...

In this paper, the transmutation of TRUs of the DUPIC (Direct Use of Spent PWR Fuel in CANDU) spent fuel has been studied with the HYPER system, which is an LBE-cooled ADS. The DUPIC concept is a synergistic combination of PWRs and CANDUs, in which PWR spent fuels are directly reutilized in CANDU reactors after a very simple re-fabrication process. In the DUPICHYPER fuel cycle, TRUs are recover...

A study of the DUPIC (Direct Use of Spent PWR Fuel In CANDU) cycle was made to analyze cycle performance relative to that of PWR and CANDU fuel cycles in terms of uranium utilization and spent fuel production efficiency. The DUPIC cycle was found to be most efficient in terms of minimizing spent fuel production as well as most efficient (within limits) in terms of maximizing natural uranium uti...
