Chernobyl Nuclear Power Plant - Objectives, tasks, structure

Radiation background in the Administrative building area is in average 65 microrentgens per hour, in the Shelter object's Observation pavilion area - 1,08 myllyrentgens per hour.
Controllable parameters of the Shelter object are within the limits established by Operational Regulations. According to monitoring systems data the maximal value of gamma - radiation rate inside the object has made 3403 Rontgens per hour, temperature near to Fuel Containing Materials is +29 degrees on Celsius. Exceeding of control levels of Shelter object condition parameters is not fixed.

Objectives, tasks, structure

Main SIP objective is transformation of the Shelter object into ecologically safe system from the point of view of personnel protection, radiological safety and environment safety.
SIP is organized on the basis of five purposes, which is necessary to achieve during its planned realization, and includes 22 tasks grouped according to these purposes.

MAIN SIP TASKS

OBJECTIVE 1. Collapse probability reduction (structural stabilization)
Task 1. Stabilisation and Shielding Design Integration and Mobilisation
Task 2. Stabilisation and Shielding of Western Section.
Task 3. Stabilisation and Shielding of Mammoth Beam and Southern Section.
Task 4. Stabilisation and Shielding of the Eastern and Northern Sections.
Task 5. Stabilisation of the Roof, Roof Supports, and Covering.
Task 6. Structural Investigation and Monitoring.
Task 7. Geotechnical Investigation.
Task 8. Seismic Characterisation and Monitoring.

OBJECTIVE 2. Collapse Consequences Reduction
Task 9. Emergency Preparedness.
Task 10. Dust Management.
Task 11. Emergency Dust Suppression System.

OBJECTIVE 3. Nuclear Safety Improvement
Task 12. Criticality Control and Nuclear Safety.
Task 13. Contained Water Management.
Task 14. Fuel Containing Material (FCM) Characterisation.

OBJECTIVE 4. Worker and Environmental Safety Improvement
Task 15. Radiological Protection Program.
Task 16. Industrial Safety, Fire Protection, Infrastructure and Access Control.
Task 17. Integrated Monitoring System.
Task 18. Integrated Database (Configuration Management).

OBJECTIVE 5. Long Term Strategy and Study for SO Conversion to an Environmentally Safe Site
Task 19. FCM Removal and Waste Management Strategy and Study.
Task 20. FCM Removal Technology Development.
Task 21. Safe Confinement Strategy.
Task 22. Implementation of a Safe Confinement to Support Deconstruction and FCM Removal.

Realization of all project tasks is interconnected. The course of works on one task determines a course of works on another. There are three types of the basic SIP stages with the purpose of the necessary information obtaining for works progress and for the project status definition:
-program – important decisions acceptance, influencing works progress or the beginning of new. 10 basic program decisions was defined, among them there are three key for successful SIP Project completion: P1 – Decision on stabilization, P8 – Decision on FCM removal strategy, P10 – Decision on New Confinement Strategy.
- regulatory – Ukrainian Regulatory Bodies permission obtaining. It was defined 18 basic regulatory stages.
- basic stages of tasks completion – stages specifying work, task completion, or completion of key activity within the task framework. It was defined 28 stages.

PROJECT IMPLEMENTATION PHASES

Phase 1: 1998 – middle of 2000 – Early Biddable Projects Stage (strategy and programs development, conceptual designing), preparatory works for Phase 2, including – implementation 2 of 5 urgent stabilization measures.
Transition period: middle 2000 – beginning of 2001 – Early Biddable Projects closeout and decision-making on the basic program stages.
Phase 2: beginning of 2001 – 2007 – equipment designing and procurement, facilities and systems construction and commissioning. This phase is characterized by Project transition to the stage of first phase results real implementation. There are, first of all, the works connected to building constructions stabilization, installation and commissioning of monitoring systems and the integrated database, FCM removal technology development and testing, water and dust management technical solutions realization, New Safe Confinement (NSC) erection and unstable constructions dismantling under its encasement. Solution of the specified tasks is supported by the Radiological Protection Program, Technical and Fire Safety ensuring, access control.

Project organizational structure
According to Memorandum of Understanding between G7 countries, European Commission and Government of Ukraine on Chernobyl NPP shutdown the special fund has been established – Chernobyl Shelter Fund (CSF) intended for assistance provision to Ukraine in existing "sarcophagus" transformation in safe and ecologically stable system by realization of the Shelter Implementation (SIP). G7 addressed to the Governments of the interested countries and to other donors to join the initiative for complete plan realization.
European Bank for Reconstruction and Development (EBRD) became the Administrator of Grants funds allocated by Chernobyl Shelter Fund’s Contributors and Donors. Ukraine and the European Bank for Reconstruction and Development signed the Framework Agreement on CSF activity in Ukraine, ratified by Verkhovna Rada of Ukraine on February 4, 1998. Taking into account Grant intended for Regulatory Bodies financing, the total cost of project’s works makes 768 million US dollars. 28 Donors countries and European Commission accumulate these funds in CSF.

Ukraine has taken obligation to allocate 50 million US dollars to Fund in form of property, works and otherwise.

SIP Management structure.

European Bank for Reconstruction and Development manages Fund Activity on behalf and under supervision of Assembly.

Assembly:
· authorizes Fund Grants allocation;
· determines basic directions of activity, financed or are subject to financing from the Fund, carries out the general supervision of their realization by Bank;
· traces pledged funds payments in Fund and provision of Ukrainian financing supplying Grants for SIP;
· examines efficiency of activity, financed from Fund’s means;
· approves Fund’s Annual Budget and Financial Reports; organizes regular annual meetings in process of which Fund’s Financial Reports for the last fiscal year are submitted for approval. Assembly can hold meetings at any time when it is necessary or expedient.

Every Fund Contributor has the right to be presented in Assembly by the plenipotentiary representative without any compensation from Fund.

The main responsibility for financial and program management of Project realization is entrusted on European Bank for Reconstruction and Development.

The control and the organization of operational safety management pertain exclusively to Chernobyl NPP. Chernobyl NPP with the Consultant support manages the Project regarding to key programs and technical designs implementation.

SIP Project Management Unit (PMU), established from SSE ChNPP personnel and the personnel of the Consultant (consortium of companies Bechtel (USA), Battelle (USA), EDF (France)), manages the Time Schedule, Scope of works, project budget, project changes, Civil work and carries out administrative contracts management.
