established the USSR in early sixties of the XXth

century

collection, transportation, processing and

disposal of LILW wastes and DSRS,

generated or used in medicine, research

institutions, various branches of industry

35 “Radon” facilities in the Soviet Union

RADON facilities

Typical historical repositories are vaults below the ground level with the volume from 200 to 9000 m3,

basement made of concrete plates,

walls made of monolithic reinforced concrete or concrete blocks,

divided with concrete or wooden walls into cells (sections),

the top is covered with reinforced concrete plates, sand and waterproof asphalt layer

Radon facilities

Designed and operated as disposal facilities for

institutional LILW without intention of the waste

retrieval

Don’t fit with the safety requirement for near

surface disposal (long lived alpha emitters, high

active DSRS etc.)

Don’t fit with the safety requirements for long term

storage (waste package inspection, retrievability

etc.)

Radon facilities

10

Operators of RADON type facilities are obliged to

perform safety assessment and upgrade safety

Decision making depends not only from the safety

issues but from socio-political, technical and

economic aspects

Most common decisions include:

decommissioning of facility

upgraded storage facility

upgraded disposal facility

Measures are often considered:

partial or complete RW retrieval and conditioning

reconstruction

11

Basic terms definition

RAW classification

special RAW and Retrievable (disposable) RAW

classes of Retrievable RAW (based on disposal option)

For Special (nonretrievable) RAW:

emplacement site and

site for conservation

Deep well injection of liquid LLW and ILW on operating

sites

Main statements of Federal Law «On Radioactive Waste Management»

12

Initial RAW Registration

Initial RAW registration is provisioned in the Article 23 of the Federal Law “On

Radioactive Waste Management” and will be implemented during the first phase of

development of the a unified state system of radioactive waste management starting

from the January 15, 2013 till December 31, 2014 inclusively.

The surveys will be carried out in all facilities having radioactive waste that are subject

for the initial registration.

Based on the survey results special commissions will draw up the acts of initial

registration, on the basis of which proposals will be developed to classify radioactive

waste storage facility into a particular category of radioactive waste storage facilities.

The State Corporation "Rosatom" has confirmed the schedule for survey and initial

registration of the storage facilities (sites) for radioactive waste generated before

15.07.2011.

The schedule was developed in accordance with the Governmental Resolution from

25.07.2012 № 767 "On carrying out the initial registration of radioactive waste"

13

Initial RAW Registration

Initial RAW registration will provide the necessary information to form a

registry of radioactive waste and the inventory of the radioactive waste

storage facilities (sites).

From a legal point of view, the initial RAW registration will allow:

• To assign the status of “accumulated waste” to the waste generated before

the Federal Law “On Radioactive Waste Management” has entered into

force

• To define the categories and types of storage facilities and of the

accumulated RAW according to the new Russian legal framework

(retrievable and special waste, the temporary and long-term storage, sites

of emplacement and sites of conservation of special waste).

Type of radioactive waste and of the category of radioactive waste storage

facility are crucial for planning of treatment of previously accumulated waste

in accordance with the requirements of the Article 24 of the Federal Law “On

Radioactive Waste Management.”

Russian Federation

«On criteria for classifying solid, liquid or gaseous waste to

radioactive waste, criteria for classifying radioactive waste to

special and removable RAW and criteria for classification of

removable RAW».

Criteria for classifying radioactive waste to special and retrievable RAW

m3, commissioned before the entry into force of the Federal Law "On the treatment of

waste ...", as well as the sediments of the storage reservoirs meet the following criteria:

• The cost of moving away,

processing, conditioning,

transportation to disposal facility

and disposal of radioactive waste

Moving away On site

disposal

• The size of the possible harm to the environment

• The cost of disposal of radioactive waste, including

conversion Site of sRAW to RAW disposal facility, its

operation and closing, its safety over the period of the

potential danger

The safety case will be developed as the project

progresses and will be used as a basis for

decision making relating to selection of the

decommissioning option.

The purpose of safety assessment to be

performed as the illustrative test case is to test

initial ideas of the waste retrieval and

improvement of technological rules for waste

retrieval procedure and/or decision making related

to the decommissioning options for historical

Radon-type facility

The assessment of the future management of

retrieved waste is not part of the current safety

assessment and safety case. This can be covered

by other relevant safety assessments addressing

the management steps for such waste, i.e. its

clearance, discharge, processing, storage, transport

and disposal

Context

43

The endpoint of the safety assessment will be the

doses for the workers as result of external

irradiation and inhalation both for normal and

accidental scenarios

For treating uncertainties in the safety assessment,

cautious assumptions will be used, but, in view of

the intervention situation, these should be as

realistic as possible;

Context

44

Timeframe for safety assessment for dose

calculation is the sum of time required all

considered technological operations. In terms of

possible accidents caused by external events the

timeframe cover all the period of waste retrieval

operations at the site

Safety assessment calculations are performed using

SAFRAN and other tools
