ASN Report 2020

Gammaster ioniser Since 2008, the company Stéris has been operating an industrial irradiator called Gammaster situated in the munic- ipality of Marseille. Gammaster treats products by ionisation (emission of gamma radiation) with the aim of sanitising, sterilising or improving the performance of materials. The facility is made up of an industrial bunker and houses sealed sources of cobalt-60 which provide the radiation necessary for its activity. ASN considers that the level of nuclear safety and radiation protection of the facility in 2020 is on the whole satisfactory. The licensee must remain attentive to the monitoring of the pressure equipment present in the facility. On completion of examination of the safety review f ile submitted by the l icensee, ASN, through resolution CODEP‑MRS-2019-048140 of 5 December 2019, has set technical requirements governing the continued operation of the facility. The licensee has produced an action plan and informs ASN of its progress every six months.
