)

F.nclosed is PAD input to UPPSS 3 & 5 DES.

Delay based partially on receipt of change in liquid source terza (10/10/74),

late input frasa SAB (hydrological parar.eters), and comI2 uter inacces sability.

Environnental Project Manager was notified informally of delay.

Input was prepared by M.A. Parsont, RAB.

Tu '3 13 PRINCIPALLY A CONSEGUENCC OF PHYSIULOGICAL MECHANISM 3 THAT CONCCNTRATE A NUNGER OF CLCHENTS THAT CAN SE PRESENT IN THE AGUEGUS ENVIRONMENT.

THE EXTENT 70 WHICH ELEMENTS ARE CONCENTRATED IN F!GH, INVERTCBRATCU, AND AQUATIC PLANTS UPON UPTAKE OR INGESTION HAS BEEN CSTIMATED. VALUCS OF RELATIVE BIOLOGICAL ACCUMULATIUN FACTORS ( RATIO OF CONCENTRATIO'! 0F NUCLICE IN ORGANISMS TO THAT IN'THE AGUEOUS ENVIn0NMENT 1 qF A NuvaER ne WATER-BORNE ELEMENTS FOR SEVERAL CAGANISMS ARE PROVIDE 0 IN TABLE 5.2.t.

Deses to aquatic plants and fish living an the discharge region due ro water uptake and ingestion (internal exposure) were calculated to be 2.3x10+1 and 2.4x10+1 mrads/ year, respectively, for MPPSS nuclear project 3 and S operation. The discharge region concentrations were those given above and it was assumed that these organisms spent all of the year 'in ustar at 10 percent of these concentrations. All calculated doses are based on standard models (Ref. 4).

The doses are quite conservative si.nce it is' highly unlikely that any of the mobile life forms will spend a significant portion of their life span in the activity concentration of the discharge region. Both radioactive decay and additional dilution would reduce the dose at other points in the river.

TAGLE 5'3.2 LISTS THE 003ES DUE TO rhE GASEOUS T '* 71.'i r N T 3,

An estimate can be made for the ingestion dose to a terrest*ial animal such r.s a duck which is assumed to consume only aquatic vegetation growing in the water in the discharge region Lnd to live year round in this ragion.

T'te duck ingestion dose was calculated to be about 1.0 rads / year, which represents an upper limit estimate since equilibrium was assumed to exist between the aquatic organisms and all radionuclides in water. A non-

%uilibrium coalition for a radionuclide in an actual exposure situation u:uld result in a snaller bicaccumulation and therefore in e smaller dose from internal e;<posure.

5. 3. 7 EV;DIATION OF PADOL'7aICAL I"iPACT The average annual dose from gascous efflueats to perrra ma; L ".cssericted areas within 50 miles of the plant is 0.002 nren/yr as shc.in in Tetble 3.3.5.

Maximum individual' doses due to liquid and gaseous efflu2nt releuas are less than 5 tren/fr uith tha exception of the dose to the thyroid of a child frca the ingestion of goat's c. ilk as seen in Table's 5.3.1 and 6.3.2.

With the a:::aption of gcat's milk consumption, these values are only a feu parcant of the natural background exposure of 0.106 rem /yr (Ref. 12), are below the normal variation in background dose, and represent no ne'asurable radiological impact.

- 6.1 Radiological Monitoring 16.1.1 Preoperational ?rogram Tae applicant has proposei an offstia preoperational radiologictl conitoring program to provide for ceasurement of bc: : ground rcaistion levels and radioactivity in the plant environs.- The lircoperational program which provides a necessary basis for the operational radiological

.:enitoring program, will also permit the applicant to train personnel, ovaluate procedures, equipment and techniques, as indicated in Regulatory Cuida 4.1.

A description of the applicant's proposed program and sampling locations is su=marized in Table 6.1.1.

The applicant has provided a commitment to monitor the radiciodine pathways discussed in Section 5.3.4 Mcre detailed information on the applicant's radiological monitoring program is presented in section 6.1 of the applicant's Environmental Report. The aoplicant proposes to initiate parts of the program two years prior to operation of the facility, with the remaining portions beginning either 6 months or 1 year prior to operation.

The Staff concludes that the preoperational monitoring program proposed ~

by the Applicant is generally acceptable, however, the following. changes are recommended to improve the effectiveness of the program:

a.

For gross S analyses (Airborne particulates and Ground Water) a value should be set above which gamma isotopes analysis of an individual 3

sample-is performed (eg. 1 pC1/m air and 30 pCi/l ' tater).-

b.

Goat milk sampling and analysis should be initiated.

c.

Analysis of I-131 in green leafy vegetables should be initiated.

d.

A soil sampling and analysis program should be initiated.

G.1. 2 Operational Program The operational offsite radiological monitoring program is conducccc to measure radiaticn levels and radioactivity in the plant environs.

It assists and provides backup support to the detailed ef fluent monitorin: -

(au T'cenmended by Pegulatory Guide 1.21) which ta naadad to va l-a t e individual and populatica s::osuras and verify prajo:cea or anticipa w:.

radioactivity concentrations.

_2 Tha applicant plans essantially to coc.:inua the prorosad preoper:tional

. program during the operating period.

Eceevar, refinaments.ay be rade in the program to refimot changes in land use or preoperadicnal tonitoring experienca.

An evaluation of the applicant's proposed operational monitorin~ program vill be performed during the operating licanse re /i -;, _nd tha de tails of the required monitoring program will be incorporated into the Environmental Technical Specifications for the operating licanse, s
