Nuclear Decommisioning in the EU: Financing Issues by A. V. Zimakov

“…The European Union has timely recognized the potential risk of lacking decommissioning financing and has stepped up certain pro-active measures in a form of non-binding recommendations on the management of decommissioning funds and binding Euratom directive setting ultimate responsibility of the state for nuclear waste utilization. The Euratom directive that is to be transposed into national legislation requires a creation of a legal framework ensuring safe accumulation of sufficient financial resources for decommissioning of nuclear facilities and further waste utilization. …”

The permeability properties of bedded coal and rock: Review and new insights by Zhixiang Song, Junwen Zhang, Lichao Zhang, Xukai Dong, Weimin Niu, Yang Zhang

“…Abstract It is beneficial to understand deeply the permeability properties of coal and rock for the stability control of mining engineering, underground engineering, oil and gas engineering, nuclear waste storage engineering, and so on. Therefore, new insights for the permeability properties of bedded coal and rock are summarized and proposed. (1) "Five guarantees" coring technology is worth for vigorous promotion and application. (2) The internal spatial fabric has the significant effect on the mechanical behavior evolution law of (bedded) coal and rock, but the effect is not dominant. (3) The permeability‐energy evolution models of (bedded) coal and rock should be constructed considering the idea of initial high in situ stress reduction, which is helpful for the energy visualization characterization of (bedded) coal and rock. …”
