[en] To make comparison and assessmemt of survey data, it is necessary to standardize the method of terrestrial and marine ecosystem survey and the analytical methods for nonradioactive pollutants. Sampling items, frequency, scope and related descriptions in ecosystem survey were rearranged systematically. Analytical methods for nonradioactive pollutants in the environment were also suggested. By standization, monitoring methods about terrestrial and marine ecosystem survey and analysis of nonradioactive pollutants became more systematic and consistent of survey data be done easily and non-efficient and economic loss at the surveying time be avoided.

[en] Deep borehole disposal involves drilling one or more boreholes into crystalline basement rock to a depth of about 5 km, emplacing waste packages in the lower 2 km of the borehole, and sealing and plugging the upper 3 km. These depths are several times deeper than for typical mined repositories. A deep borehole field test (DBFT) is proposed to confirm the safety and feasibility of the deep borehole concept. The primary goals are to demonstrate the construction and characterization of deep boreholes, demonstrate the equipment and operations used for safe waste handling and emplacement downhole, study geologic controls on waste form stability and isolation, and evaluate the overall safety and practicality of the concept. The test will be conducted using simulated waste packages; no radioactive wastes will be handled at the deep borehole field test site. A key component of the DBFT is an engineering demonstration of the equipment and operations needed to transport waste packages to the site, move packages between the transportation and emplacement systems, and lower or retrieve packages into or out of the borehole. This paper describes the conceptualization of test package handling, from transportation and receipt through the interface with the borehole. It also describes the use of an integrated test facility to check out equipment prior to deployment at the DBFT site, and performance of the engineering demonstration at the DBFT site. (authors)

[en] 'Full text:' Some activities on nuclear sites such as decommissioning generate large volumes of uncontaminated waste. What is an appropriate degree of rigour to apply to demonstrate that wastes are not contaminated, and are therefore suitable for release from regulatory control so they can be reused, recycled or disposed of in conventional waste facilities? Is there a level of demonstration that is practical to demonstrate on the scale required? If not, what are the practical alternatives for dealing with such wastes? (author)

[en] The capillary barrier is necessary to make larger the gap of particle diameter of sand and gravel material. The functional deterioration of capillary barriers in service for dozens of years is of concern because of the transport of sand particles to the lower gravel layer due to an earthquake. The authors found that the inclusion of sand particles into the lower layer can be reduced by using the crushed shell particles instead of gravel in the capillary barrier. In this study, the authors make clear the type, particle size of crushed shell and crushing methods of shells by column test using one dimensional cylindrical vessel and by laboratory experiment using a small sized shaking table. It is concluded that a paper selection of size and distribution of the crushed shell particles leads to a practical development of the capillary barrier which has long term durability and provides some possible solution to a recycling of fishery byproduct waste.

[en] The analysis of preliminary results of the inventory accounting of nuclear- and radiological-hazardous facilities (NRHF) of different types has been performed taking into consideration their present state including ranking of NRHF according to their hazard degree, ownership type, subordination and other characteristics. The criteria for categorizing as nuclear legacy and general approaches of the strategic planning have been established. A brief description of algorithms for operation management concerning the nuclear legacy for the period up to 2025 is also given

[en] This paper models the effects of three different options for domestic waste collection using data from three Hampshire authorities: (i) joint working between neighbouring waste collection authorities; (ii) basing vehicles at waste disposal sites; and (iii) alternate weekly collection of residual waste and dry recyclables. A vehicle mileage savings of 3% was modelled for joint working, where existing vehicle allocations to depots were maintained, which increased to 5.9% when vehicles were re-allocated to depots optimally. Vehicle mileage was reduced by 13.5% when the collection rounds were based out of the two waste disposal sites rather than out of the existing depots, suggesting that the former could be the most effective place to keep vehicles providing that travel arrangements for the crews could be made. Alternate weekly collection was modelled to reduce vehicle mileage by around 8% and time taken by 14%, when compared with a typical scenario of weekly collection of residual and fortnightly collection of recyclable waste. These results were based on an assumption that 20% of the residual waste would be directly diverted into the dry recyclables waste stream
