RADIOLOGICAL ASSESS!!ENT BRAtlCH TEClitlICAL SPECIFICATI0!! POSITI0tlS OCONEE UllITS 1, 2, & 3

1) Replace specification 4.11.2 with the followi.ng:

A semiannual census of milch animals shall be conducted to determine their location and number with respect to the site. The census shall be conducted under the following circumstances:

1.

Within a 1 mile radius from the plant site or the 15 mrem /yr isodose line--whichever is larger: A door to door or equivalent counting technique shall be utilized.*

2.

Within 5 miles:

Enumeration by using referenced information from such as county agricultural agents or other reliable sources.

3.

These locations will be incorporated into the milk monitoring program as soon as practicable and in such a manner as to ensure that.the locations selected for sampling are adequate to show that the provisions of Specification 3.10.1 are satisfied.

For sample locations within the 15 arem/yr isodose line, sampling shall be weekly during the season that animals are on pasture.

2) Add the following specifications:

4.11.3 During the seasons that animals producing milk ** for human consumption are on pasture, samples of fresh milk will be obtained from these animals at locations and frequencies shown in Table 4.11-1, and analyzed for their radioiodine content, calculated as iodine-131. Analysis will be carried out within eight days (one I-131 half-life) of samoling.

Suitable analytical procedures will be used to determine the radioiodine concentri ion to a sensitivity of 0.5 picocuries per liter of milk at the time of sampling.

l'or activity levels at or above 0.5 picocuries per liter the overall error (one sigma confidence level) of the analysis will be within 25%.

Results will be reported, with associated calculated error, as picoeuries of I-131 per liter of milk at the time of sampling.

4.11.4 Reports shall be submitted in accordance with the requirements of sectiori 6.6 Plant Reporting Requirements.

4.11.5 Deviations are permitted from the required sampling schedule if specimens are unavailable due to hazardous conditions or to malfunction of automatic sampling equipment.

If the latter, corrective actions shall be completed prior to the end of the next sampling period.

All deviations from the sampling schedule shall be described in the semiannual reports.

t

3) Add the following section between Specification and Bases in Section 4.11:

Reporting Requirements Repor+.ing requirements for environmental monitorina are given in Sectii n 6.6 1,3.g(6). These require notification of the AEC within one we'k if individual milk samples show I-131 concentrations in excess of 10 picocuries per liter or greater or if any environmental medium, other than those associated with gaseous radiciodine releases, show a measured level of radioactivity in excess of ten times the control station value.

Likewise, notification of the AEC is required within 30 days if measured values show levels of radio-activity in excess of 4.8 picocuries of I-131 per liter of milk or 4 times the control station value.

4) Add the following sentence in the Bases:

A concentration of 2.4 picocuries per liter of milk will result in a dose to the thyroid of an infant (2 gram thyroid) of 15 arem per year, based upon the consumption of one liter per day of fresh milk for the year.

5) The felletting deficiencic: cre noted in T:ble: 4.11-1 ar.d 4.11-2:

The applicant should incorporate these samples into the program or provide the basis for a conclusion that such sampling is impossible or inappropriate.

a) Soil sampling has been omitted.

Soil sampling should be included as follows:

i - Type Samples - soil ii - Schedul t - once per 3 years iii - Analysis - Gamma Analysis, Sr-90 on collection.

b) Meat and poultry sampling has been omitted.

Meat and poultry sampling should be included as follows:

1 - Type Samples - 1 sample or more of meat, poultry and eggs from animals fed on crops grown within 10 miles of the facility at the prevailing downwind direction or where & ;r.kir.3 water is supplied from a downstream source.

1 sample from major game species in areas where these provide an important source of dietary protein,

.e ii - Schedule - Semiannually 111 - Analysis - Gamma Analysis on edible portions.

c) The control, sample location has not been specified for milk.

One sample from milking animals at a control location (10-20 miles distant and in the least prevalent wind direction) should be included.

d) Ground water samples should be analyzed quarterly by gamma analysis and analyzed for tritium.

~

6) The attached table (Attachment #1) entitled, " Environmental Monitoring Program Report" should be incorporated into section 6.6.1 Routine Reports.

7) The four reporting requirements listed below should be incorporated into section 6.6.2 Non-Routine Reports.

ReportinL equirements R

1.

If individual milk samples show I-131 concentrations of 10 picocuries per liter or_ greater, a plan shall be submitted within one week advising the AEC of the proposed action to ensure the plant related annual doses will be within the design objective of 15 mrem /yr to the thyroid of any individual.

2.

If milk samples collected over a calendar quarter show average concentrations of 4.8 picoeuries per liter or greater, a plan shall

-be submitted within 30 days advising the AEC of the proposed action to ensure the plant related annual doses will be within the design objective of 15 mrem /yr to the thyroid of any individual.

3.

If, during any six-menth report period, a measured level of radioactivity in any environmental medium other than those associated with gaseous radiciodine releases exceeds ten times the control station value, a written notification will be submitted within one. week advising the AEC of this condition. This notification should include an evaluation of any release conditions, environmental factors, or other aspects necessary to explain the anomalous result.

a.

. 4.

If, during any six-month report period, a measured level of radioactivity in any environmental medium other than those associated with gaseous radiciodine releases exceeds four times the control station value, a written notification will be submitted within 30 days advising the AEC of this condition. This notification should include an evaluation of any release conditions, environmental factors, or other aspects necessary to explain the anomalous result.

In section 6.6.1.3, " Semiannual Operating Report", add a subsection 8) for. reporting occupational personnel radiation exposure according to.the format given in attachment #2.
