Liquid discharges

The impacts from liquid discharges from the facility during normal operation are quantified (Table 4.3) simple by dividing the discharge rate of each radionuclide by the Screening Discharge Rate . The discharge rates are extracted by SAFRAN from the table of release rates of the linked area or facility, added by the user in the system description module. Default values of the Screening Discharge Rate for routine releases are available in the SAFRAN Internal Database (see Database tables) and can be entered by the user directly in Table 4.3 or indirectly thorough the database (see Values provide by SAFRAN and user-defined vaules in database).

Table 4.3. Quantification of impacts of the type liquid discharges for normal operation scenarios

RN – radionuclide, HQ – Hazard Quotient, SDM – System Description Module, SDB – SAFRAN Internal Database, N/A – not applicable. The cell marked in read is used in the Analysis Module for comparison of hazards.

Definition of columns in Table 4.3:

  • Column 1. Short name of the radionuclide (RN).
  • Column 2. Radionuclide discharge rate.
  • Column 3. Screening Discharge Rate for normal operation.
  • Column 4. Hazards Quotient.

Columns in Table 4.3 that can be modified by the user: The user can modify the following columns: column 3– for entering own values of the Screening Discharge Rate (no).
