DRAWING-UP OF MANAGEMENT ROUTES FOR REACTOR WASTE BASED ON INDUSTRIAL PRACTICES IN FRANCE AND SPAIN.

Objective

THE OBJECTIVE IS TO CONTRIBUTE TO THE IMPLEMENTATION OF A JOINT STUDY ON MANAGEMENT OPTIONS FOR LWR WASTE BY DRAWING UP TWO BASIC ROUTES EMPHASIZING THE TREATMENT-CONDITIONING AND PACKAGING ASPECTS. THE ASSESSMENT OF MANAGEMENT ROUTES ON THE BASIS OF ECONOMIC AND RADIOLOGICAL CRITERIA IS BASED ON THE FRENCH AND SPANISH CONCEPTS AND INDUSTRIAL PRACTICES.
BASIC INFORMATION AND DATA RELATED TO THE OPERATING EXPERIENCE IN FRANCE AND SPAIN, IS MADE AVAILABLE BY RESPECTIVELY EDF AND INYPSA WHO COOPERATE WITH SGN AS CONTRACTORS. MORE SPECIFICALLY, THE CONTRIBUTION OF INYPSA APPLIES TO THE STUDY OF THE BWR WASTE MANAGEMENT OPTIONS BASED ON THE SPANISH EXPERIENCE.
The French treatment systems vary according to the waste activity levels. They include:
the boron recycle system (TEU);
the liquid waste treatment system (TEV);
the gaseous waste treatment system (TEG);
the solid waste treatment system (TES).
These are adapted to common primary waste inventories and discharges limits.

Released activity and related radionuclide spectrum are studied for the assessment of the radiological impact to the public and dose rates to the workers are assessed.

Cost elements such as:
characteristics of the major equipment used (as base value for the cost determination procedure);
estimated volume of the treatment systems building (for the assessment of the civil works costs);
general information (provided by EDF for the French experience) (to serve as a basis of comparison for operation cost assessment);
are considered.

In addition, the impact of using mobile instead of fixed concreting facilities on the capital and operating costs is examined.
2.1.1. DEFINITION OF TYPICAL PRIMARY WASTE INVENTORIES RESULTING FROM NORMAL OPERATION OF 900 MWE PWR AND BWR IN FRANCE AND SPAIN.

2.1.2. DEFINITION OF DISCHARGE LIMITS, WASTE ACCEPTANCE CRITERIA AND TRANSPORT REGULATIONS.

2.1.3. DRAWING UP TWO BASIC MANAGEMENT ROUTES ACCORDING TO THE FRENCH AND SPANISH PRACTICES CONSIDERING A 20 GWE NUCLEAR PARK (80% PWR AND 20% BWR) AND GROUPING REACTORS BY FOUR UNITS.

2.1.4. SENSITIVITY STUDIES TO DETERMINE THE IMPACT OF TREATMENT AND CONDITIONING PARAMETERS ON WASTE PRODUCT CHARACTERISTICS AND QUANTITIES, AND THE COST OF MAJOR COMPONENTS.

2.1.5 ASSESSMENT OF THE OCCUPATIONAL EXPOSURE.

2.1.6 ASSESSMENT OF THE RADIOLOGICAL IMPACT TO THE PUBLIC FROM THE RADIONUCLIDE CONTENTS OF EACH MAIN EFFLUENTS GENERATED IN THE TWO BASIC MANAGEMENT ROUTES AND THE VARIANTS.
