Radiation safety during remediation of the SevRAO facilities: 10 years of regulatory experience.

In compliance with the fundamentals of the government's policy in the field of nuclear and radiation safety approved by the President of the Russian Federation, Russia has developed a national program for decommissioning of its nuclear legacy. Under this program, the State Atomic Energy Corporation 'Rosatom' is carrying out remediation of a Site for Temporary Storage of spent nuclear fuel (SNF) and radioactive waste (RW) at Andreeva Bay located in Northwest Russia. The short term plan includes implementation of the most critical stage of remediation, which involves the recovery of SNF from what have historically been poorly maintained storage facilities. SNF and RW are stored in non-standard conditions in tanks designed in some cases for other purposes. It is planned to transport recovered SNF to PA 'Mayak' in the southern Urals. This article analyses the current state of the radiation safety supervision of workers and the public in terms of the regulatory preparedness to implement effective supervision of radiation safety during radiation-hazardous operations. It presents the results of long-term radiation monitoring, which serve as informative indicators of the effectiveness of the site remediation and describes the evolving radiation situation. The state of radiation protection and health care service support for emergency preparedness is characterized by the need to further study the issues of the regulator-operator interactions to prevent and mitigate consequences of a radiological accident at the facility. Having in mind the continuing intensification of practical management activities related to SNF and RW in the whole of northwest Russia, it is reasonable to coordinate the activities of the supervision bodies within a strategic master plan. Arrangements for this master plan are discussed, including a proposed programme of actions to enhance the regulatory supervision in order to support accelerated mitigation of threats related to the nuclear legacy in the area.

A new approach to the assessment of health status of the working people is proposed. Qualitative determinations of the "cost" of body adaptation to occupational and nonoccupational factors could be used as a health standard. The adaptation "cost" was calculated by means of integral indicators, characterizing body system response to human vital activity factors. Some approaches to the development of the "alphabet" of human functional states formed during the process of adaptation to vital activity factors. The proposed methods of assessing health levels can be used in the development of automated systems for mass prenosologic examinations and dispensarization of the population and also in workers' health management.

The article presents definition of "stress at work" term, covers principles and methods of occupational medicine so as to specify criteria for evaluation and regulation of stress at work. Technology of the criteria application is exemplified by influence of occupational stress on reliability of astronauts activities in simulated docking during spaceflight.
