HC Deb 18 January 1990 vol 165 c361W
Ms. Walley

To ask the Secretary of State for the Environment what are the implications of the findings of the European Commission's PAGIS study into the suitability of British geology for high-level radioactive waste disposal for the search by Nirex to establish a deep disposal facility for intermediate-level and low-level radioactive wastes.

Mr. Trippier

Nirex is not responsible for heat generating or high-level radioactive waste. However, it takes note of the results of studies such as PAGIS. The PAGIS report pointed out the long-term containment benefits that would stem from excavating a repository in hard rock with sedimentary cover as advocated by Nirex.

Mr. Malcolm Bruce

To ask the Secretary of State for the Environment when he expects Nirex to report on the results of its site investigation work at Dounreay and Sellafield.

Mr. Trippier

At present Nirex is awaiting the result of planning applications for the drilling of boreholes at both Dounreay and Sellafield. If permission is granted, Nirex will need to carry out a drilling programme of 18 months, alongside other detailed site investigation work, before any report is expected.

Mr. Malcolm Bruce

To ask the Secretary of State for the Environment if he will publish an outline timetable relating to the commissioning of a repository for radioactive waste.

Mr. Trippier

I understand that Nirex has a target date of 2005 for the commissioning of a deep repository. This assumes some eight years to excavate and contruct the repository. Therefore between 1990 and 1997 Nirex will have to undertake the necessary site investigations and obtain planning permission to construct a repository. There will be a public inquiry.
