Database tables

To open SAFRAN Database window - select Database from the main menu.

SAFRAN database contains the values for the following parameters:

• Specific Gamma Ray Dose Constant (SGRDC) (Sv/h per Bq)

• Screening dose rate for accidents

• Airborne release fraction

• Screening releases inside for accidents

• Screening releases outside for accidents

• Momentary breathing rate

• Dose coefficients for internal exposure via inhalation

• Dose coefficients for external exposure from the cloud

• Dispersion factors

• Dose conversion factor for accidental releases to air

• Screening dose rate for normal operation

• Screening release rates to the atmosphere for normal operation conditions

• Screening discharge rates for normal operation conditions

• Dose calculation factors for releases to the atmosphere under normal operation conditions

• Dose calculation factors for discharges into a sewer or river under normal operation conditions

• Clearance levels for bulk amounts of material

Values are stored in database tables. Each table presents one of the parameters. Depending of the nature of parameter, rows of the table keep values of the parameter for different “indexes”, such as radionuclides, distances etc.

Table may contain several values with the same indexes. User tells to SAFRAN which value to use in safety assessments by checking the checkbox located in the column Default.

SAFRAN database is supplied with the values for all parameters, but user may add own site-specific values (and use them as default). Site specific values may be calculated with SAFCALC module or obtained from any other sources such as calculation programs or site-specific databases.
