Session 6.2: Disposal
- Travis Tate (U.S. Nuclear Regulatory Commission)
- Mika Kari (Tampere University)
For the disposal, intermediate storage and transport of spent nuclear fuel a number of properties of each fuel assembly must be determined, both for operational and safeguards needs. Important examples of these parameters are decay power, multiplicity, burn-up (BU), initial enrichment (IE), cooling time (CT), completeness of fuel assemblies, weight, amount of fissile material and nuclide...
Finland was the first country to license a spent nuclear fuel encapsulation plant and a disposal facility. Posiva Ltd (Posiva) submitted the construction license application (CLA) in the end of 2012. Radiation and Nuclear Safety Authority (STUK) made the review of the CLA and in February 2015 the statement and safety evaluation report were submitted to the Ministry of Economic Affairs and...
In the Russian Federation, more than 6,000 tons of vitrified HLW from the reprocessing of SNF have been accumulated, which are planned to be disposed of in a deep geological repository. Spent nuclear fuel composition is determined by various types of processed SNF (Russian nuclear power reactors VVER-440 and BN-600, research reactors, etc.), technological features of processing and cooling...
The question of disposing of radioactive waste after it has been generated is an ongoing issue for the nuclear industry. Currently one of the preferred solutions is to encase the waste in containment structures and bury it deep underground until the radioactivity has decayed to safe levels. In order to prevent future human intrusion, the repositories containing the waste much be clearly marked...
