RADON facilities

The system of RADON enterprises was

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

16 of them in the Russian Federation

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

depth –3-6 m, width – 5,5 up to 32 m length – 16 up to 100 m.

Radon facilities

Radon facilities

10

Designed and operated as disposal facilities for

institutional LILW without intention of the waste

retrieval

Now do not 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

11

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

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

sites

Regulations of VLLW, LLW, ILW disposal

The criterions for classification of RAW are given in the

Decree №1069 from 19.10.2012 by the Government of the

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

Special RAW

• The collective effective dose for the entire period

of the potential danger

• The risk of potential exposure

Retrievable RAW

RAW, including:

•RAW generated:

•in result of implementation of the state program of armaments and state defense order

•In result of the use of nuclear weapon for peaceful purposes

•In result of nuclear and (or) radiation accident in nuclear facility

•liquid RAW, accumulated in surface water-storage facilities, totaling more than 25000

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

RAW storage and its sanitary protection zone located outside the boundaries of settlements, protected areas, coastal protection

strips and water protection zones of water bodies, and other security protection zones

Working Group Objectives

17

to adopt the safety assessment methodology

presented in the GSG-3 The Safety Case and

Safety Assessment for the Predisposal

Management of Radioactive Waste to the RADON

type facility needs

to develop illustrative test case for applying this

methodology to historical waste retrieval from

RADON type facility using SAFRAN tool

to provide Member States with the supporting

information for decision making regarding the

future of existing historical RADON type facilities
