The principal factors that affected the scope of scientific investigations at Yucca Mountain over the last 20 years included both regulatory and technical aspects. Examples of regulatory factors include the regulations themselves as well as the associated quality assurance requirements. Examples of technical factors include the repository and waste package designs, new information that affected the post-closure safety basis, and technical reviews from peers, stakeholders and the regulators.

What are the essential elements of technically credible, workable, and publicly acceptable regulations for disposal (in geologic repositories)?

Andras goal of Sustainability

CoRWM’s remit is to provide independent scrutiny and advice to Government on the long-term management, including storage and disposal, of radioactive wastes and materials that may be declared to be wastes. This is the first of three reports to be produced in 2009 that describes the results of the Committee’s scrutiny work in 2008 and the first part of 2009 and provides advice to Government.

This paper is a first consideration of the MRWS White Paper on the framework for geological disposal. It is based primarily on discussions in Working Group D on July 21 2008 but also draws on CoRWM’s informal comments on the draft White Paper, on CoRWM’s recommendations as reported in 2006 and on an overview of the responses to the consultation that preceded the White Paper. There have been few opportunities, as yet, to discuss the White Paper through the CoRWM PSE process.

This second version of the Olkiluoto Site Report, produced by the OMTF (Olkiluoto Modelling Task Force), updates the Olkiluoto Site Report 2004 (Posiva 2005) with the data and knowledge obtained up to December 2005.<br/>The main product of the modelling has been to develop a descriptive model of the site (the Site Descriptive Model), i.e. a model describing the geometry, properties of the bedrock and the water and the associated interacting processes and mechanisms.
