- 341 - Monitoring of operational dosimetry is governed by the "provisions of the prevention plan for the contractor(s) and of each work permit issued to the contractor." With regard to radiation protection training, the ILL has created its own training module which is presented to any new intervention staff prior to issue of the authorisation for access to a controlled zone. These requirements are specified in the Quality Assurance Notes (NAQ) and radiation protection and security instructions. Methods for monitoring subcontracted activities The ILL specifies that "as stipulated in NAQ N° 34, any subcontracted intervention carried out on the site is supervised by the ILL manager who requested the works, as need be in association with persons from ILL acting as inspectors or providing assistance, for example for measures relating to radiation protection. Each service may be the subject of a quality audit during the course of the intervention and an evaluation of the subcontractor. These arrangements are specified in the work permit issued. NAQ N° 45 "Quality audit and evaluation of subcontractors" specifies the performance methods". In this way all manufacturing or maintenance work on Equipment Important for Safety and Monitored Quality Equipment (EISMQS) performed off the site or on the site is supervised by an ILL manager and carried out in accordance with the requirements of the Quality Organisation Manual. The ILL underlines the fact that the subcontracted tests and maintenance operations (in particular concerning the HEPA filters and PAI) remain supervised by the ILL operations, safety and radiation protection teams. Steps envisaged for tightening the requirements concerning the conditions for the use of outside contractors Following the investigation, the ILL undertook to continue to review its organisation of the surveillance of contractors performing monitored quality activities. In the light of the above, the steps already taken and ILL's undertaking to continue its review of its organisation of the surveillance of contractors performing monitored quality activities, ASN has no particular remarks.
