SUBJECT:

Oconee Nuclear Station Radiological Environmental Monitoring Program -

File 0S-778.00 I am making the requests listed below as a result of the closing of the Clemson Water Plant. As of July 1 of this  !

year, the University's drinking water plant was shut down  !

with no plans to restart the facility. Clemson University now obtains drinking water from the Anderson water system.

- Delete the drinking water location 065, Clemson, from i Table A5.0-2 and Figure.A5.0-1 at the next revision to the ODCM. Redmarked copies of the needed changes are attached. In addition to the deletion, please correct the sector listed for location 073 from.NNW to NW.  :

t i

p L (_/ - Identify-in the next Semi-Annual Effluent Release ,

Report the deletion of.the Clemson drinking. water

.samplespoint from.0conee's Radiological Environmental Monitoring Program.

- Review the ODCM and make any necessary changes to effluent dose calculation parameters due to the plant's ,

closing.

- Review the need to add a drinking water location  :

further downstream of Anderson, if possible. Oconee Technical Specification 4.11, Table 4.11-1, specifies that the monitoring program include.3 drinking water  :

sites. Anderson is currently the only site downstream

of plant discharges. Ser, ca and Greenville both use l Lake Keowee as their reservoir. We have installed a <

sampler to collect from the water used.to supply the steam plant at the University. This water is collected from the same line that fed the water plant. The L difference is that the sample will be raw. water rather than finished water. This sample point will be considered a special supplemental sample since it is ,

neither a drinking water or surface water sample, and it will not be included in the ODCM. The sample ,

results will be trended and used in the evaluation of fO surface water and drinking water results as needed.

~

A1.1 LIQUID RADWASTE PROCESSING ,

The liquid radwaste system at Oconee Nuclear Station (ONS) is used to collect  !

and treat fluid chemical and radiochemical by-products of unit operation. The  ;

systems produce effluents which can be reused in the plant or discharged in i small, dilute quantities to the environment. The means of treatment vary with  ;

waste type and desired product in the various systems:  ;

i A) Filtration - waste sources are filtered prior to processing as ,

necessary.  ;

B) Ion Exchange - ion exchange is used to remove radioactive ions from '

solution. Also, ion exchange is normally used in removing cations (cobalt, manganese) and anions (chloride, fluoride) from evaporator feed and/or distillates in order to purify the distillates for reuse as makeup water. Distillate from the Waste Evaporator System or the '

Waste and Recycle Evaporator can be treated by this method.

{

C) Gas Stripping - removal of gaseous radioactive fission products is -

accomplished in Evaporators and the venting of atmospheric holdup tanks.

D) Distillation - production of pure water from the waste by boiling it p) away from the contaminated solution which originally contained it is accomplished by both evaporators. Proper control of the process will yield water which can be reused for makeup. Polishing of this product can be achieved by ion exchange as pointed out above.

E) Concentration - in all Evaporators, radioactivity and dissolved chemicals are concentrated as water is boiled away. In the case of the Waste Evaporator, the volume of water containing waste chemicals

.and radionuclides is. reduced so that the waste may be more easily and cheaply solidified and shipped for burial. In the case of the VR dryer, all water is removed and the dry salts are solidified for burial. ,

Figure A1.0-1 is a schematic representation of the liquid radwaste system at ~l Oconee. l l

A1.2 GASEOUS WASTE PROCESSING h '

Ihe purpose of the gaseous waste disposal system is to: f

(1)" Maintain"a~non oxidizing cover gas of nitrogen in tanks and equipment that contain potentially radioactive gas.

(2). Hold up radioactive gas for decay.  ;

(3) Release gases (radioactive or non-radioactive) to the atmosphere under controlled conditions. .

During power operation of the facilities, radioactive materials released to the atmosphere in gaseous effluents include low concentrations of fission product noble gases (krypton and xenon), halogens (mostly iodines), tritium  !

contained in water vapor and particulate material including both fission  :

products and activated corrosion products. ,

The primary source of gaseous radioactive wastes is from the degassing of the primary coolant during letdown of the cooling water into the various holding  :

tanks. Additional sources of gaseous waste activity include the auxiliary

' building exhaust, spent fuel area exhaust, the discharge from the steam jet air ejectors, purging of -the reactor containment building and ventilation air exhausted from the turbine building, i

l  % All components that can contain potentially radioactive gases are vented to a l

I< vent header. The vent gases are subsequently drawn from this vent header by

,d one of three waste gas compressors or a waste gas exhauster. The waste gas compressor discharges through a waste gas separator to one of seven waste gas

. tanks. The waste gas tanks and the. waste gas exhauster discharge to the unit

! vont after passing through a filter bank consisting of a profilter, an ,

absolute filter, and a charcoal filter.  ;

Radioactive gasas may be released inside the reactor containment building when :

components of the primary system are opened to the building atmosphere for

, operational reasons or where minor leaks occur in the primary system. Prior l to access, the reactor containment atmosphere will be monitored for activity ,

and, when necessary, purged through profilters, high-efficiency particulate air (HEPA) filters and-charcoal adsorbers and released to atmosphere through a the unit vent. The purge equipment is sized for a flow rate of 50,000 cfm providing 'approximately 1.5 air changes per hour in the reactor building.

Units 1; 2 & 3 have a separate vent stack from each reactor building.

The gaseous waste handling and treatment systems for the Oconee Nuclear Station are shown schematically in Fig. A1.0-2, 1

A2.0 RELEASE RATE CALCULATION j

' x.( s) . ,

Generic release rate calculations are presented in Section 1.0; these calcu-i lations will be used to calculate release rates from Oconee Nuclear Station. ,

i A2.1 LIQUID RELEASE RATE CALCULATIONS i i

There are two potential release points at Oconee, the liquid radwaste effluent ,

line to the Keowee Hydroelectric Unit Tailrace and the #3 Chemical Treatment  !

Pond effluent line to the Keowee River. i A2.1.1 Liquid Radwaste Effluent Line To The Keowee Hydroelectric Unit Tailrace  ;

To simplify calculations for the liquid radwaste effluent line, it is assumed that no activity above background is present in the #3 Chemical Treatment Pond  !

effluent. This assumption shall be confirmed by radiation monitoring and/or -

the sampling of the pond's radioactive inputs, and by periodic analysis of the ,

composite. sample collected at the #3 Chemical Treatment Pond discharge. For the liquid radwaste effluent line the following calculation shall be performed .i to determine a discharge flow, in gpm:

f = the undiluted effluent flow, in spm.

Cg = the concentration of radionuclide, 'i', in undiluted effluent as determined by laboratory analyses, in 11Ci/ml.  ;

MPC = the. concentration of radionuclide, 'i', from 10CFR20, Appendix B.

f Table II, Column 2. If radionuclide, 'i', is a dissolved noble gas, r the MPCg = 2.0E-4 pCi/ml.

F = the dilution flow available, in gpm typical flow rates are:

3.41E+04 gpm (based on a leakage rate of 38 cfs, plus the Keowee Hydro Fire Protection - LVR mixing line whose flow rate is 38 cfs) 2.9E+6 gpm (based on one hydro unit operating at 50% power, 6600 cis) o- = the recirculation factor.at equilibrium is 1.0. (See Section 1.1) b l

( ) A2.1.2 #3 Chemical Treatment Pond Effluent Line v

The #3 Chemica1' Treatment Pond effluent is the release point for station effluents that are normally considered to be non-radioactive; that is, the

' pond's effluent will not normally contain measurable activity above background. It is assumed that no activity is present in the effluent until indicated by radiation monitoring measurements on the pond's inputs and/or by periodic analyses of the composite sample collected at the pond's discharge point. Inputs to this pond include the plant's yard drain system, the decant water from the Powdex system, the discharge from the Turbine Building Sump system, and Radwaste Facility monitor tanks whose contents have been determined to be below background. Inputs that have radiation monitors associated with them will be set to assure that Technical Specification 3.9.1 ,

will not be exceeded.

The #3 Chemical Treatment Pond may also be the discharge path for large volumes of slightly contaminated water following a primary secondary leak so long as administrative procedures are implemented to assure that release rate calculations similiar to that used in Section A2.1.1 are performed, that all detectable radionuclides will be accounted for, and that no statica limits will be exceeded.

A2.1.3 Low Pressure Service Water Effluent Line The Low Pressure Service water effluent is normally considered nonradioactive;

/~'g that is, it is unlikely the effluent will contain measurable activity above

( ) background. It is assumed that no activity is present in the effluent until ,

indicated by radiation monitoring measurements. Radiation monitoring alarm setpoints, in conjunction with administrative controls, assure that release limits are not exceeded.

[ ) 'A2.2 GASEOUS RELEASE RATE CALCULATIONS FOR SEMI-ELEVATED RELEASE POINTS vs The unit vents are the release points for waste gau decay tanks, containment building purges,.the condenser air ejector, and. auxiliary building ventila-tion. The unit vent is treated as a semi-elevated release point. The applicable dispersion and deposition parameters are provided in Tables A4.0-1a and A4.0-1b respectively.

The condenser air ejector effluent is normally considered nonradioactive; that is, it is unlikely the effluent will contain measureable activity above background. It is assumed that no activity is present in the effluent until indicated by radiation monitoring measurements and by analyses of periodic samples collected from this source. Radiation monitoring alarm / trip setpoints in conjunction with administrative controls assure that release limits are not exceeded; see section on radiation monitoring setpoints.

The following calculations, when solved for flowrate, are the release rates for noble gases and for radioiodines, particulates and other radionuclides with half-lives greater than 8 days; the most conservative of release rates  !

calculated in A2.2.1 and A2.2.2 shall control the release rates for a single release point. ,

These monitors i alarm on low flow; the minimum flow alare level for the liquid monitors is 3 gallons per minute and for all gas monitors, except in the Radwaste Facility, is 7 standard cubic feet per minute. These monitors measure the activity in the liquid or gas volume exposed to the detector and are independent of flow i rate if a minimum flow rate is assured.

'A5.0 RADIOLOGICAL ENVIRONMENTAL MONITORING The radiological environmental monitoring progr.im shall be conducted in <

s accordance with Technical Specification 4.11.

The monitoring program locations and analyses are given in Tables AS.0-1 through A5.0-3-and Figure AS 0-1.

Site specific characteristics make ground water sampling and food product i sampling unnecessary. : Ground water recharge is from~ precipitation and the -

ground water gradient is toward the effluent discharge area; therefore, contamination of ground water from liquid effluents is highly; improbable. .g However,=some ground water sampling is performed to verify this. Food products will not be sampled since lake water irrigation of crops is not _ .; '

. practiced in the vicinity.

The laboratory performing the radiological environmental analyses shall i participate in an.interlaboratory comparison program which has been approved.

by the NRC. This' program is the Environmental Protection Agency's (EPA's)

Environmental Radioactivity Laboratory Intercomparison Studies (Crosscheck)  !

Program, our participation code is CP, The dates of the' land-use census that was used to identify the controlling receptor locations was 08/02/89 - 08/10/89.
