OE-3 2015-02: Atmospheric Dispersion Parameter (x/Q) for Calculation of Co-located Worker Dose
This Operating Experience Level 3 (OE-3) document informs the complex of the issuance of a technical document on the basis for the default atmospheric dispersion parameter (x/Q) used to determine co-located worker dose in accident analysis calculations. It also provides recommendations for ensuring an appropriate x/Q is used where the default x/Q may not result in a conservative estimate of dispersion.
