Radioactive waste disposal dating

The 116-N-3 crib was constructed as a replacement liquid radioactive waste disposal facility for the 116-N-l crib and trench and first received N Reactor effluent in 1983. The 116-N-3 trench was put in full service in September 1985 (DOE-RL 1990). Between these two dates, both the 116-N-l and the 116-N-3 facilities were in service. Both the 116-N-3 crib and trench are covered by precast concrete panels to prevent access by the local fauna to contaminated water. 

A second problem associated with nuclear power is waste disposal. Although the amormt of nuclear fuel used in electricity generation is small compared to other fuels, the products of the reaction are radioactive and have very long half-lives (thousands of years or more). What do we do with this waste Currently, in the United States, nuclear waste is stored on site at the nuclear power plants. A permanent disposal site was being developed in Yucca Mountain, Nevada. The site had originally been scheduled to be operational in 2010, and that date was later delayed to 2017. However, the Obama administration determined that the Yucca Mountain site was untenable, and in the spring of 2010, the license application to develop this... 

Record the contents of each waste container. Each radioactive waste container must have a record of the identity of radioisotope(s), the activity, and the date (see Figure 13.6). For short-lived isotopes, the date should be the date of assay of the activity, which should be very close to the disposal date. 

To date, the Swiss National Co-operative for the Disposal of Radioactive Waste (Nagra) has carried out three major safety assessments for a HLW repository in crystalline and argillaceous rocks (Fig. 1). This paper will concentrate on the near-field chemical containment aspects identified in the two crystalline host rock assessments (Projekt Gewahr and Kristallin-1 Nagra 1985 and 1994a respectively). Note that the near-field of a Nagra HLW repository in sediments would differ only in that the backfill thickness may be reduced and that it also would contain steel tunnel liners (Nagra 1989).
