Special Features of the Personnel Radiation Protection Assurance During SNF and RW Management at SevRAO Facilities

Abstract

Today, overall decommissioning of nuclear submarines (NS) belonging to the Northern Fleet RF and remediation of available sites of temporary storaoe (STS) of the spent nuclear fuel (SNF) and radioactive waste (RW) came into the stage of practical implementation. The most large-scale remedial operations are to be performed at Facility No I of the Federal state unitary enterprise ``Northern enterprise for radioactive waste management{''} (FSUE ``SevRAO{''}) located on the Kola Peninsula in Andreeva bay. The Federal Medical-Biological Agency of the Russian Federation (FMBA) is responsible for the regulation of radiation protection of workers and the public at operation of radiation hazardous facilities. Having in mind provisions of the regulative documents, FMBA of Russia presses for the consistent optimization principle introduction of the personnel radiation protection into practice of SevRAO facilities. The paper presents the findings of investigations performed by specialists from the State research centre - Institute of Biophysics regarding the assessment of the radiation monitoring system existing at SevRAO facility No 1; it also demonstrates some revealed features of the radiation situation generation on-site and in workshops at STS in Andreeva Bay; in addition, it proposes some recommendations relating to ALARA technique implementation in the course of SNF and RW managernent operations. This work has been undertaken under NRPA financing.
