REVISION 5 PRAIRIE ISLAND NUCLEAR GENERATING PLANT OFFSITE DOSE CALCULATION MANUAL (00CM)

CHANGES TO TABLE 3.2-1, piI VALUES FOR INFANTS Errors resulted in this table when t'he NRC no longer required pathways -

other than inhalation to be considered in showing compliance with the 10 CFR Part 20 release rate limit for todines, particulates and tritium.

The errors developed when this table was modified by removing the Pi columns for all pathways except inhalation. The correct process is to use Table E-10 of Regulatory Guide 1.109 and choose the largest dose factor for each isotope.

We have computed corrected PiI values. A revised Table 3.2-1 is 1 attached.

i O Significant short-tem batch releases of long-lived radioactive particulates and crititan will result from contairement purges. Calculations will be made for these releases separately to further sasure compliance with 10 CFR Part 20 prior to release. These calculations will be used only to decomine whether or not the purge release will be allowed to occur. Sourca tems will be decomined from the  ;

results of isotopic smalyses of samples from coatsimment prior to release. Equation -

3.2.1 will be us d in conjunction with the following reistionship to demonstrate that the hatch release does not exceed the does race limit:

BL = 1500 - (D, - D,) 0.2-2) where j

BL =  !!miting dose rate for the batch, mrem /yr; Dy a previols week's doses from all vent releases, mrem /yr; t

Dp a previous week's deses from all purge releases mrem /yr.

i f 3.2.3 Critical Receptor fdentifleation i

The atmospheric dispersion parameters given in Appendix A will be used to identify the critical receptor. Compliance with Part 20 will always be shown at the site

  • j boundary location with the highest X/Q. As discussed previously, weekly and batch

)

I dose calculations will be performed at this location. The critical site boundary (location, based upon long term ground level releases %/Q (Table A-3), is 0.36 miles in the WNW sector.
