Training objectives

Upon completion of training trainees should be able to:

1. List the Bulgarian/national normative documents in the area of decommissioning and decommissioning related activities.

2. Describe/Characterize the documents, related to: decommissioning, RAW and SNF management, radiation protection and control, environment protection etc, explaining the scope of relevant normative document(s). Identify which are covered by regulation documents.


4

According to SUNEA (article 15, para. 4, clause 6, as well as article 38, para. 1, clause 2), for Decommissioning it is required to issue a permission. The permissions related to Decommissioning of Nuclear Facilities are described in “Regulation for the order of issuing licenses and permissions for safe use of nuclear energy”.The whole process of decommissioning of Nuclear Facilities is developed, analysed, planned and justified in a plan for decommissioning, which is submitted to Nuclear Regulatory agency (NRA) at least 3 years prior to closure for decommissioning.

4.1 Process of licensing


5

The Decommissioning plan shall comprise:

• Description of facility, site, areas with specific statute, circumstances and events that have occurred during the period of operation

• Justification of the selected version of decommissioning;

• Plan-schedule and description of activities on Decommissioning;

• Classification of systems and facilities

• ……….

Process of licensing


6


The Decommissioning plan shall comprise (cont.):

• …………

• Concept, programmes and procedures for radiation protection, programmes for RAW management, for safety assessment, for radiation monitoring of the site.

• Internal emergency plan; physical protection measures

• Evaluation of financial resources required


7


Documents required for issuance of Decommissioning permission:

• safety assessment report• decommissioning plan • ТР for operation of nuclear facility;• Instructions for operation of systems remaining in

operation;• Decision on Assessment of the Environmental

Impact;• Other documents (common for all activities, for

which a permission in line with art. 35 is required)


8

Documents required for the issuance of permission for the stage of decommissioning:

For the corresponding stage:– project for organization and performance of activities

– an updated plan;

– ТР for the operation of nuclear facility, including specific limitations and operation conditions;

– Operation Instruction for systems remaining in operation;

– An updated report for assessment of safety;

For stages, related to dismantling or closure of NPP:– a decision on the Assessment of Impact on Environment

Regulation on safety during decommissioning of nuclear facilities

It arranges the main issues related to safety of nuclear facilities during decommissioning, resulting from the specifics of decommissioning activities

Subject of this regulation are legal entity that design, build, commission, operate and decommission nuclear facilities.

Object of regulation:

a) Planning of safe decommissioning;

b) Basic safety requirements during decommissioning;

c) Management of activities in the period of decommissioning.

4.2 National normative base related to decommissioning


10


Planning of safe decommissioning includes:• Preliminary and interim planning and objectives• Determine the concept and develop the plan for

decommissioning • Planning and justification of safety during decommissioning


11


Regulation of major requirements during Decommissioning in:

• Maintenance of safety critical systems and facilities• Decontamination and dismantling of facilities• Radiation protection and management of radioactive waste • Completion of a decommissioning stage


12


Management of activities during the period of decommissioning:

• Organization and control• Personnel qualification and training• emergency planning and physical protection• quality assurance and documentation


13

4.3 National normative base related to RAW and SNF management

• National strategy for safe management of Spent Fuel and RAW

• Regulation for ensuring safety in spent fuel management • Regulation for safety of radioactive waste management• Regulation № 46 for transport of radioactive waste• Regulation for ensuring physical protection of nuclear facilities, nuclear material and radioactive waste


14

Regulation for providing safety in spent nuclear fuel management

Scope:• Principles and criteria for safe Spent Nuclear Fuel management • Nuclear safety (general requirements, requirements for spent nuclear fuel

storage, requirements for transport-technological equipment, ..)• Operation and decommissioning of facilities for Spent Nuclear Fuel

management• Radiation protection• Safety assessment• Quality assurance


15

Regulation on radioactive waste management safety

Scope:• Requirements on radioactive waste (RAW) management

– Categorization of solid RAW– Radiation protection– RAW generation and reprocessing– RAW storage– RAW disposal

• Requirements for safety of facilities for RAW management – Facilities for reprocessing and storage (selection, design, operation,

decommissioning)– Facilities for disposal (selection, design, operation, closure, control over

closure)– Assessment of safety of facilities for RAW management)


16

• Regulation on procedure for providing physical protection of nuclear facilities, nuclear material and radioactive substances – It specifies the conditions and arrangements for assurance of physical

protection for nuclear facilities, nuclear material and radioactive substances in their use, storage and transportation

• Regulation № 46 for transport of radioactive substances

– Arranges air, water and land transport of radioactive substances

• Regulation on the conditions and arrangements for transfer of radioactive waste to the State Enterprise "Radioactive waste"– It determines the conditions, arrangements and terms for RAW transfer to

the State Enterprise "Radioactive waste", as well as categories and types of RAW that are not liable to transferring to the state enterprise.

19

National normative base related to radiation protection

Regulation on radiation protection in activities with sources of ionizing radiation, 2004

• It specifies the requirements and rules for radiation protection in performing activities with sources of ionizing radiation /SIR/ and conditions and arrangements for accounting Sources of Ionizing Radiation.

• It determines levels for free of control radioactive substances or materials, containing radioactive substances


20

Regulation on basic norms of radiation protection (BNRP), 2004

• BNRP aim at eliminating the occurrence of deterministic effects and reducing the probability of stochastic effects occurrence to a level, considered to be acceptable, according to international recommendations.

• Subject of regulation are the main requirements and measures for carrying out the activities on nuclear power and SIR usage within the meaning of SUNEA.



21

Regulation on conditions and arrangements for determining areas with special status around nuclear facilities and sites with sources of ionizing radiation, Decree of The Council of Ministers № 187 d.d. 28.07.2004, promulgated, SG, issue 69 d.d. 6.08.2004

• Section II of the Regulation specifying the requirements to radiation monitoring in the areas of special status (radiation protected area and observed area). In this regulation is explained the way of organizing radiation monitoring and the controlled characteristics are listed
