Waste storage, radioactive

Note that the concentrations of additive oxides differ. No attempt has been made to scale this effect with additive concentration). This curious reduction effect is not easily understood but emphasizes the complex nature of the glasses including the possible cooperative involvement of the multiple components. Similarly complex phenomena might influence leaching behavior in the complex, multicomponent glasses of interest for radioactive waste storage. [Pg.153]

Americium is released into surface water primarily from plutonium production reactors, nuclear fuel reprocessing facilities, or in nuclear accidents. It may also be released from radioactive waste storage facilities. Since 241Pu decays into 241 Am,241 Am is also released as a result of 241Pu releases. Water sampling data were used to estimate effluent releases from the SRS from the plant s start up in... [Pg.144]

Apatite is being considered as a barrier that will prevent the leakage of radioactive nuclei from the radioactive waste storage. Because of the similarity in the chemical and spectral features REE have been chosen as a model of the fission products of the actinides. For this reason it is of importance to recognize whether the elements are incorporated in the bulk of the barrier, or adsorbed on the surface where they can be subjected to leaching out (Martin et al. 1996 Martin et al. 1999a Martin et al. 1999b).

The Applications of Laser-induced Time-resolved Spectroscopic Techniques chapter starts with a short description of laser-induced spectroscopies, which may be used in combination with laser-induced luminescence, namely Breakdown, Raman and Second Harmonic Generation. The chapter contains several examples of the application of laser-based spectroscopies in remote sensing and radiometric sorting of minerals. The proljlem of minerals as geomaterials for radioactive waste storage is also considered. [Pg.362]

A joint placement with other radiation hazardous or nuclear objects allows construction and operation cost to be substantially reduced. For example, building in the same site a radioactive waste storage facility and a long-term SNF storage facility enables use for both objects not only one and the same transport infrastructure but in part an imdergroimd one (access galleries, laboratories etc.).

Since 1950s, there have been three traditional fields of application for molecular sieves and porous materials 1) separation, purification, drying and environment treatment process 2) petroleum refining, petrochemical, coal and fine chemical industries 3) ion-exchange, detergent industry, radioactive waste storage, and treatment of liquid waste. In addition to the traditional application fields, zeolites and related porous materials may also find applications in new areas such as microelectronics and molecular device manufacture. [Pg.9]

The world s worst radioactive contamination (twice that of Chernobyl) is at Mayak in Russia. This has resulted from explosion of a radioactive waste storage unit on September 29, 1957 and deliberate dumping of liquid waste into the Techa River in 1949-1956 94... [Pg.7]

Vitrification is particularly useful for remediation of soils contaminated with radioactive heavy metals. The radioactive heavy metals are encapsulated in a highly inert, nonporous matrix, which can be stored permanently in underground secured radioactive waste storage facilities currently under development in some Asian countries. Vitrification can also be used for sediments and slndge pollnted by heavy metals. [Pg.441]

The test layout (Fig. 2) consists in placing two heaters at the end of a drift of 2.28 m diameter and 70.4m length especially bored for this purpose. The diameter and length of the heaters (0.9m and 4.54m respectively) corresponds to the actual dimensions of the canister envisaged for radioactive waste storage. The heaters are placed in the axis of the drift at a Im distance from each other. [Pg.319]

The results of these analyses are transferred electronically (via the LIMS) to workstations, where the data are validated and verified, and reports are prepared. After the data are reported and accepted by the client, sample residues are moved to the radioactive waste storage facility for disposal (see Section 13.4.5) or returned to the client. The design features of individual laboratory areas are described in Sections 13.3 to 13.6. [Pg.264]

EPA sets standards for radioactive waste storage and disposal facilities. We can t treat plutonium or other radioactive materials to get rid of rfieir radioactivity. We can only isolate and store them until they decay. The extremely long half-lives of some plutonium radioisotopes make the management of spent nuclear fuel, and wastes from nuclear weapons facilities a difficult problem. [Pg.266]

An alternative perspective is present in corrosion engineer anecdotes. "Nope, we don t have any corrosion problems in this plant. The pumps wear out every six weeks and we replace them." Or alternatively, "We just dump the scrap here and as soon as we can fill a railroad car we haul it to a hole a hundred miles away cuid bury it. Some day when the corrosion finishes the junk off, we ll build condominiums on the land." Or yet another one - "Hey, would you believe that with six months data they want me to warrant that tank for 50 years of radioactive waste storage " Yes, these do represent some famous last words. Enough for the anecdotal description we are not gathered here to be entertained. [Pg.1]

The FPU accommodates two KLT-40C reactor plants with pressurized water reactors, two steam turbine plants with TK - 35/38 - 3.4 turbines of a co-generation type and TAG8123EUL5B electric generators, facilities for nuclear fuel management and solid and liquid radioactive wastes storage, ecological section.

The Project provides for the installation of facilities for nuclear refueling and spent nuclear fuel storage on board the FPU without using special service vessels. Radioactive production waste is also stored on board the FPU. Thus, the design autonomous operation period (operation without supplies replenishment) of the FPU is determined by the c q)acity of spent nuclear fuel and radioactive waste storage tanks and periodicity of docking. With -0.54 load factor, which corresponds to the pessimistic consumption forecast, the autonomous operation of the FPU is ensured by four nuclear core sets and makes 13-15 years. After the lapse of this period the FPU is replaced with a similar one. [Pg.61]
