In late 1998 the Committee on Nuclear Regulatory Activities agreed that the Working Group on Inspection Practices [WGIP] should discuss the subject of effectiveness of regulatory inspections and produce a report. This work would augment the work that it and the International Atomic Agency (reference 1) were doing on the subject of regulatory effectiveness.
Accordingly, WGIP discussed the subject at a meeting in Den Haag held on 4-6 May 1999. Because there was no obvious consensus at the meeting on the subject, a sub-group was formed to brainstorm the issue.
This report outlines the work of the sub-group and the subsequent discussions, comments and conclusions of WGIP.
