6 OPERATIONAL WASTE CHARACTERISTICS
6.1 Introduction
During the operation of the UK EPR, waste streams will be generated. Liquid effluent generated
during the operation of the UK EPR will be treated to generate a clean discharge. The
treatment of liquid effluent will generate solid waste as a by product. For completeness this
waste is included below.
In this section these waste streams are documented in terms of estimated total quantities and
annual arisings. The physical, chemical and radiological characterisation is presented.
6.2 Waste Characterisation Methodology
The waste streams that will be generated from operation of a UK EPR have been characterised
by EdF by examining the waste arisings from several operating French reactors. These are
expected values and variations in their absolute accuracy does not effect the content of this
strategy.
6.3 Summary of Operational Waste Arisings
The UK EPR will generate operational wastes that will be classified as ILW or LLW based on
beta-gamma activity only. Table 2 shows a summary of the expected waste arisings from the
UK EPR. Figure 2 and Figure 3 illustrate the percentage make-up of the wastes when
segregated into LLW and ILW arisings.
