In 1960's, the large technical bases of the Northern Fleet were arranged on the Kola Peninsula. These bases were involved in support of nuclear submarines performing acceptance and storage of radioactive waste (RW) and spent nuclear fuel (SNF). Since 1985, the waste acceptance has been stopped and the technical bases changed their functions to serve as sites of temporary storage (STS). According to the RF Government Directive of 09 February 2000 No 220-r, the STS were put under Rosatom responsibility in order to conduct operations dealing with the SNF and RW management being accumulated during the naval activity and originated from dismantlement of nuclear submarines and surface ships equipped with nuclear powered installations, as well as to carry out environmental remediation of radiation hazardous facilities in this region. The international collaborative assistance is very important to increase effectiveness of such works. This paper includes the findings of cooperation between the Federal Medical Biological Agency (FMBA) and Norwegian Radiation Protection Authority (NRPA) in radiation protection of the public in the course of the STS remediation. Since 2004, the following works has been carried out in this direction: - radiation threat assessment and identification of the priority directions of radiation and hygienic studies; - radiation situation inspections on-site and within the coastal offshore waters at different stage of remediation; - development of the documents including the criteria for the STS remediation and guidelines for radiation monitoring to control the mentioned criteria compliance; - development of the radio-ecological geo-information system. The developed criteria consider four basic options of the STS remediation - renovation, conversion, conservation and liquidation. The main (dose) and derived remediation levels have been determined for each option. The resulted from monitoring radiation parameters - including contents of {sup 137}Cs, {sup 90}Sr and {sup 60}Co in samples of soil, vegetation, seawater, seaweeds, bottom sediments, invertebrates and vertebrates, gamma dose rate values - are integrated in the database, which is the component of the geo-information system. The developed regulative and methodical documents and the geo-information system have been introduced in Regional Management-120 under FMBA of Russia, which is responsible for the radiation safety supervision, Centre of Hygiene and Epidemiology-120 under FMBA of Russia, which carries out regulatory radiation control, and in the operating organization involved in the STS remediation and responsible for radiation protection of workers and public. The works completed have permitted to solve the majority of problems in enhancement of radiation and hygienic supervision of SevRAO operation. However, some relevant questions in this area need additional efforts. In particular, in the course of specification of the design solutions, obtaining additional data on the radiation situation parameters and clarification of the prognostic assessments, the necessity will certainly arise to amend the regulatory documents taking the adopted design solutions into account. We are on the way to real results. Much has been done for the first time, and although it is difficult to foresee all future problems and challenges, our knowledge, experience and close cooperation permit to assess the prospects confidently.
