Institutional waste

RAW from the use of radioactive materials in industry, medicine and research (institutional waste) has been disposed of, or stored, in three near­surface repositories, Richard, Bratrstvi and Hostim since the early 1960s (Figs. 12.4 and 12.5). The inventory of the abandoned limestone mine repos­itory, called Richard, is given in Table 12.3 (Czech National Report, 2008).

In addition to the waste disposed of, RAW that does not meet waste acceptance criteria and is awaiting disposal in a deep geological repository

(DGR), described further in Section 12.3.1, is stored here. It consists mainly of sealed radionuclide sources of 137Cs, 60Co, 241Am and 239Pu. Inventory of the abandoned uranium mine Bratstvi located near the town of Jachymov, which has been in operation since 1974, is given in Table 12.4. The first near­surface repository, Hostim, near the town of Beroun, was closed in 1965. It contains only very low-activity waste not exceeding 1011Bq.
