Schwartz, P E

To better support emergency preparedness, General Public Utilities (GPU) Nuclear has investigated the frequency of occurrence of the mesoscale ocean breeze at the Oyster Creek Nuclear Generating Station (OCNGS). Through the analysis of the horizontal wind direction and temperature patterns, simple identification of the ocean breeze along with a plume tracking procedure has been developed and incorporated into the site's emergency plant to better safeguard the public with sophisticated protective action measures in case of a nonroutine release. The ocean breeze will frequently produce wind trajectory fields within the plant's emergency planning zone that are different from the normal gradient wind flow. This could greatly alter proper protective action measures since most utilities employ straight-line trajectory air dispersion models. Knowledge of the existence of the ocean breeze and the location of the ocean breeze front become important in the results generated from the straight-line Gaussian dose calculation methodology and in the further development of a more complex dose assessment model. This paper describes the verification and existence of the sea breeze phenomenon and the incorporation of its effects into the OCNGS emergency plan.
