Document Control Desk Washington, D. C. 20555 Perry Nuclear Power Plant Docket No. 50-440 Semiannual Radioactive Effluent Release Report Centlement We are hereby submitting the Semiannual Radioactive Effluent Release Report for i the Perry Nuclear Power Plant, Unit 1, for the period of July 1 to December 31, 1989. This report meets the requirements of Regulatory Guide 1.21, as supplemented by Perry Technical Specification Section 6.9.1.7. All effluent releases were within the concentration and release limits specified in the Radiological Effluent Technical Specifications.

L Enclosure A of this letter provides additional information for the two comments from the NRC letter dated June 5, 1989, regarding acceptance of the PNPP ODCM, Rev. 3 (TAC No. 69181). This information is a follow-up to our response which was submitted to you with the previous Semiannual Radioactive Ef fluent Release Report (PY-CE1/NRR-1056L), dated August 29, 1989.

t If you have any questions, please feel free to call.

Very truly ours, 4

1. Dilution Factors for the Potable Vater Pathway for Radioactive Liquid Effluent ,

Releases from PNPP l In our previous response, dated August 29, 1989, ve stated we vould review the i inputs used to determine the dilution factors for the potable water ingestion pathway. The review consisted of a survey to determine changes in potable water systems using Lake Erie as a source, within 50 miles of PNPP. This resulted in some changes to Table 5.1-10 of the PNPP Environmental Report -

Operating License Stage. The changes included:

s

a. Lake County Vest System - new facility l

b. Lake County East System - new facility using the intake tunnel formerly used by IRC Fibers Co.

c. Ohio Vater Service (OVC) East System - system replaced by Lake County East System.

d. Kent County (Ontario) Vater Supply - new facility.

e. Ashtabula System and Ohio American Vater Service Co. are the same facility.

f. Elyria/Lorain Vater Systems determined to be outside the 50 mile radius.

g. Painesville Vater System was incorrectly listed as 3.9 miles and was revised to agree with Table 5.1-10 of the ER-OLS.

h. Population numbers (served by listed systems) were revised.

A revised table incorporating these changes is provided along with corresponding changes to the Maximum Exposed Individual and Total Population Dilution ractors.

The new Dilution Factor values vere incorporated into the ODCM, Table 2.3-10, by TC-8, which is included with the Semiannual Radioactive Effluent Release Report, Attachment No. 9.  ;

Maximum Exposed Individual Dilution Factor l The revised nearest potable water supply is the Lake County East Vater intake,

3.5 miles to the vest-south-west of PNPP (formerly the IRC Fibers Company -

l. intake). Data presented in the Perry Environmental Report - Operating License Stage, Table 5.1-10, " Annual Average Dilution Factors for the Lake Water Intakes within 50 Miles of PNPP", gives a maximum individual dose dilution f actor of 32.2 (dilution factor unadjusted for current frequency). This new Dilution Factor for the Maximum Exposed Individual represents a 2% change from

, the previous value of 31.5.

2. Milk Sample Control Station ,

TC-7 to the ODCM includes the revised distance for Milk Control Station 51 (Rettgers Farm). In addition, a new milk control location (No. 69, John Rhodes Farm), located in the SSV meteorological sector, has been added to the ,

REMP sample program, and added to the ODCH by TC 8. The Rhodes farm was incorporated since the SSV meteorological sector represents the least prevalent vind direction. Both TC's are included in the Semiannual Radiological Effluent Release Report, Attachment 9.
