Dear Mr. D'Angelo:
As I mentioned in our' telephone conversation on April 19, Battelle has recently undertaken a project for the U.S. Nuclear Regulatory Commission, OfficeofNuclearRegulatoryResearch(RES). This project, under the purview
'of Jack M.~ Bell at RES (FTS 492-3747),willexaminethepotentialenvironmental
~
significance of accumulation and reconcentration of radioactive materials associated with low-level liquid effluents at the Catawba, McGuire, and Rancho Seco nuclear power plants.
I have attached a copy of the statement of work from this project for your information.
The project will rely on existing information and data. describing liquid effluents, effluent systems, and system operations to provide the basis for estimating actual / potential accumulation of radioactive materials at these S
three plants.. During the planning for this project, a number of Licensee-reports were identified as likely information resources. These included
- $afety Analysis Reports.(relevant sections), Technical
- Specifications (relevant sections).-Offsite Dose Calculation Manuals, Semiannual Radioactive Effluent Release Reports, and Radiolo
-As you mentioned during our.gical Environmental Monitoring Program'Re) orts.-
conversation, recent events at the plant lave resulted in the development of additional, more specific information regarding-liquid. effluents and effluent systems at Rancho Seco.
Because this information is critical to'the' project, I am requesting your assistance in obtaining the necessary reports.from the Licensee.
Inasmuch asjyou.may be aware of other potentially useful sources of information,Lplease
. contact me at the above number.
I will be contacting you again in the near.-
i future to schedule a brief site visit and will keep you apprised of our project activities.
Thank you for-your assistance and I look forward to meeting you
- during the future site visit.

1.0 OBJECTIVE OF PROPOSED WORK
1.1 BACKGROUND
Licuid effluent containing low levels of radioactive materials may.be releasec finto or via certain disposal systems that subsequently accumulate and/or reconcentrate the radioactive materials. The reconcentrated radioactive
' materials may then present an increased hazard to workers and/or the public.
An example of such a situation is the reconcentration of radioactive materials in municipal sewer systems.
In several documented cases, radionuclides dis-charged to municipal sewer systems in accordance with applicable U.S. Nuclear -
Regulatory Commission (NRC) regulations have been found to collect and recon-centrate in sewage treatment plant sludge. Treatment of this sludge by:
- incineration leads to further reconcentration resulting in an' increased poten-tial for sewer worker., and members of the public to receive unacceptable levels of radiation dose.
Other effiuent-systems that accumulate and reconcentrate contaminants are systems.that make use of retention ponds for settling and/or evaporation. -
In these situations, sw-level effluent is discharged to a pond system where short-lived radionuclides are allowed to decay and particulate materials.to settle out of the liquid phase. In closed-pond systems, aqueous wastes.are held and allowed to evaporate while open systems discharge the aqueous wastes after -sufficient decay and particulate removal has -occurred.
In some instances, pond influent may be treated through the _ addition of agents to enhance the L
settling process. = Contaminant materials will collect on-the bottom of the-
' pond where, over time, a layer of sludge is formed.
Effluent / waste managtment practices for settling pond systems may include periodic removal of accumuisted sludge or retention for the operating life of the-system.
Three commercial nuclear power stations currently make use of retention
. ponds in their -liquid effluent. systems. and 'are of specific interest to.the
- NRC. The plants me Rancho Seco, operated by the Sacramento Municipal' Utility District, and the Catawba and McGuire plants, operated.by Duke Power. - Rancho Seco has been the. focus of recent NRC attention.as a result of'small leaks in its steam generation system which led to releases of radioactive materials to
.the environment via liquid effluent. These releases occurred primarily between 1980 and:1984,.during which time approximately 1.7 curies of mixed fission and. activation products, and 500 curies of tritium were released to the environ-ment (NUREG/CR-2907); _Those releases and their potential. significance in the environment were the subject of an evaluation conducted by Oak Ridge National
. Laboratory (NUREG/CR-4286).
11.2l OBJECTIVES The objective of this project is to prepare a report for the NRC that 1) documents the. technical information necessary to determine whether or not-
.there~is a need for regulatory action with regard t6 accumulation and recon-centration of radioactive materials in low-level liquid effluent systems, and s
- e i
- 2) identifies alternate regulatory actions, if needed, to resolve any identified
, ' L problems.

SUMMARY
OF PRIOR EFFORTS i<
During the past 15 years, staff of Pacific Northwest Laboratory (PNL) i have been actively involved in the fields of expertise directly related to F
this project. An area of particular expertise is modeling and evaluation
- of radiological and nonradiolo ical pollutants encompassing waste effluent L
- analysis, waste treatment, eff vent modeling through surface and ground waters, air emissions modeling, environmental pathway modeling, and occupational and public radiation dose assessment. PNL has developed models to estimate the -
potential radiation doses that workers and members of the public might receive-p from a wide variety. of exposure pathways and situations.
Exposure pathway models developed by PNL address direct. exposure to pene-
[
trating radiation, inhalation following atmospheric releases or resuspension.
n l '. f of radionuclides in the environment, and ingestion of contaminated food products.
Ex osure conditions addressed by these models include routine and l-accidental re eases from operating nuclear facilities, releases during decon-Li
.tamination and decommissionin, and releases from dis)osal of nuclear waste.
L An example ofia model recenti -developed by PNL for tle NRC is theLONSITE/MAXII h
computer. program. This computer model was developed to assist the NRC in evaluating applications from licensees for permission to dispose limited-1
. quantities of low activity material-onsite.
PNLL recently. completed a project for the NRC'to evaluate the nature and magnitude of potential radiation doses' to sewer workers and members of the public as a result of exposure to radioactive materials during-various phases of sewer system operations and-sewage sludge processing and disposa1Lactivities.
- l 3.0 WORK TO BE PERFORMED AND EXPECTED RESULTS Three commercial nuclear-power stations currently make use of retention ponds in their liquid effluent systes. The plants are
- Rancho Seco, operated by the Sacramento Municipal Utility District, end the Catawba and McGuire plants, operated by Duke Power. Such liquid effluent systems are designed to allow time for cooling, decay, and removal of contaminants prior to release of liquid effluent to the environment.
In some instances, the ponds may retain D1 liquid effluent for the p rpose of evaporation. -Experience with the operation L-7 of liquid-waste ponds ind cates that particulate and other contaminant materials will accumulate in a-thin and relatively concentrated layer of silt / sludge at the bottom of the pond.

3.1' WORK SCOPE In order to provide the NRC with the technical information necessary to determine whether or not there is a need for regulatory action with regard to accumulation and reconcentration of radioactive materials in low-level liquid affluent $ystems, PNL proposes the following tasks:
Task 1 - Characterize Existino Liquid Efflueit Systems-and Practices The objective of this task is to charatterize and estimate the actual /
potential accumulation of radioactive mater als associated with low-level liquid effluent at the three reactor facilities.
PNL will. obtain and review data and infomation relative to liquid effluent, effluent systems, existing 's operations at the three plants. Anticipated sources of information and syste include Safety Analysis Reports, Technical Specifications, Offsite Dose Calculation Manuals, Semiannual Radioactive Effluent Release Report, and Radio-logical Environmental Monitoring Program Reports.
It is anticipated that one fact-finding visit will be made to each site.
From these and other potential sources,' PNL will extract and evaluate available-data describing liquid effluent characteristics including volume; chemistry, and other relevant parameters. Available information '
radioactivity, discharge environment (structure, liquid retention time, cleanup-regarding the practices 'etc.) and plant effluent and waste management practices and pro-
- cedures-wl11 also be evaluated.
Task:2 - Identify and Characterize the' Types of Effluent Systems and Processes t'
Likely to Reconcentrate Effluent Contaminants The objective of this task is to provide the NRC with information that will allow it to review other licensed facilities for effluent systems with
~
a potentia 1'for accumulating / reconcentrating radioactive materials associated with low-level liquid effluents.
.. -In this task, PNL will draw upon its expertise and industry experience to identify and characterize the types of systems where effluents are released to closed or limited dilution-environments that may result in accumulation and/or reconcentration of radioactive materials.
Information will be compiled
-that summarizes past experience with accumulation / reconcentration,.and describes the nature of the physical-and-chemical processes that lead to accumulation.
Task 2 - Evaluate the Nature and Approximate Maanitude of Potential Worker-and Population Exposures.
The objective of-this' task is to evaluate the nature and approximate m
magnitude of potential radiation doses to workers and members of the public as a result of exposure to radioactive materials estimated to have accumulated as a result of low-level liquid effluent discharges to ponds at the Rancho Seco, McGuire, and Catawba power plants, including any future processing and disposal of these materials. During the initial phase of this task, PNL will identify
- r.7 and characterize the credible pathways for worker and/or public exposure to
'these radioactive materials and incorporate them in detailed exposure scenar6 for analysis.

,p Potential. radiation doses'will be calculated on the basis of radionuclide inventory estimates developed in Task 1 as well as inventory estimates based on maximum allowed discharges and the. exposure scenarios developed in this task. The results of these calculations will'be theoretical estimates of J,
potential-radiation dose to workers and members of the public. Calculated doses will-be compared to existing dose standards.
This task will make use of the staff and approach from the evaluation of worker and public exposure to radioactive materials discharged to municipal.
sewer systems described in Section 5.0 of this 189.
Task 4 - Project Menacement and Reporting The PNL Project Manager will meet with the NRC Project Manager at the
- beginning'of this project to discuss work plans. The PNL Project Manager will prepare a detailed Project Management Plan (PMP).for review by the NRC-Project Manager. Project scope, objectives, and purpose will be clearly stated and agreed upon. The PNL Project Manager will then' conduct the project in accordance with the PMP. Monthly letter status reports will be provided as discussed in Section 6.1 of this proposal.
A report will be pre >ared that sumarizes and describes the investigations, methods,- and results of t11s project. Three copies of this report will be submitted to the NRC Project Manager in draft form for NRC review and coment. -
Following incorporation of NRC coments, a final camera-ready report will be h
prepared for publication by the NRC at a NUREG/CR report..

L 5.0 RELATIONSHIP TO OTHER PROJECTS PNL 'recently completed a pro ect for the NRC to evaluate the nature and J
approximate magnitude of. potentia worker and public doses from exposure to
'l l
radionuclides in sewage sludge during its treatment and disposal. Sewer system and sewage sludge treatment and disposal ~ practices were reviewed, and reference facilities and processes were characterized to provide the basis for identifying potential pathways for exposure to radioactive materials.
?
q h
Twelve conservative but credible exposure scenarios were developed to characterize potential exposures to radioactive materials during sewer system r
1 operations, sewage sludge treatment.and. disposal activities, and during the extended time frame.following sewage sludge disposal. Two sets of dose calcu-lations were performed; one to evaluate potential doses based on documented cases of sewer system contamination and' a second, more conservative set, based i
l' on theoretical discharges to the sewer at maximum allowable levels. This approach provided an evaluation of actual radionuclide discharges, as well as
-a screening of radionuclides and exposure situations to identify and separate L
those that were clearly of no concern from those that require additional:de-tailed. analysis.
J In another recent project for the. NRC, PNL produced mainframe and personal
<L-[
computer versions of the ONSITE/MAXII ' computer software package. This_ software was designed for use by the NRC in reviewing requests by licensees-for onsite disposal-of low-activity wastes. Pathways addressed by the' software included j
exposure.to penetrating radiation from external sources of various geometries, l
inhalation.of ' airborne radionuclides, and ingestion of terrestrial or aquatic foods or drinking water containi.ng tadionuclides..
3 PNL has also conducted a study for the NRC concerning residual ra'dio--
L activity from decommissioning nuclear facilities. That project consisted'of~
L 11): development of a: technical basis for specification of techniques and 1
1 instrumentation to measure residual radioactivity for license termination and u
cost' analysis, 2) development of a technical basis for translating measured
. residual radioactive contamination to human doses, and.3) preparation of cost -
