1. lNTf10 DUCT 10N in accordance with the Unique Reportng Roquirements of Technical Spocification 0.9.2h (2) applicablo during the reporting period, this report summarizos the Effluent Rokmso Data for Peach Bottom Atomic Power Station Units 2 and 3 for the period January 1 through Juno 30,1991. The notations E and E- are usod to donoto positivo and negativo exponents to the bar.o 10, rospectively.

Tho roloaso of radioactivo rnatorials during the reporting porkx1 was withiri the Technical Specif6 cation lirnits. Tho Off-Sito Doso Calculation Manual (ODCM) was revised durinD the reporting period. Revisions mado woro:

1. The addition of a Gradient factor in the maximum permissabio roloaso rato equation.

This was nocessitated by the installation of a now liquid radioactive wasto diffuser in the dischargo canal.

2. The renaming of an ODCM air particulato and air iodino location and the relochtlon of TLD sampling points.
3. Changos in the description of the rocombinor hydrogen analyzers and the gasos usod in their calibration to solloct curront usaDO.

A copy c: the revisod ODCM is attachod to this report.

Thoro woro no known unplanned releases of liquid radioactivo matorial.
