ONSITE GROUND/SURFACE WATER MONITORING QUESTIONNAIRE T Onsite Radiological Effluent/REMP Monitoring Program Phas'e Near term response)* YIV_ Nn 1. Does the licensee have radioactive groundwater monitoring wells onsite?If YES: How many wells: RNP does not have dedicated on-site radioactive groundwater monitoring wells. RNP monitors the discharge from the site deep-well pumps used for plant makeup for tritiumn gaminma and emtiting isotopes.
The deep-well pumps deliver water from an aquifer located beneath the RNP site. RNP also monitors an artesian well located just off-site (located at the base of the Lake Robinson Dam).for trilium and gamma emitting isotopes.Where are they located (e.g., distributed around/throughout the site, in a particular region of the site and/or near particular buildings/structures, etc.)(a.) within the Protected Area (b.) within the Radiologically Restricted Area (c.) within the owner-controlled area (d.) at what frequency does the licensee sample/analyze the wells (e.) for what radionuclides does the licensee monitor Gamma emitters (gamma Spec)If Yes -at what MDA 12 No[] Z 12 12 12 12 12 12 12 12 Tritium Gross Beta Other: If Yes -at what MDA If Yes -at what MDA E2 12 12 12 If Yes -at what MDA 2. If the licensee does NOT have an onsite radioactive groundwater monitoring program: (a.) Does ýýthe licensee plan to implement a groundwater 12 12 monitoring program?RNP is working with the industry and other stakeholders to identify enhancements to our existing controls to further miintnize or prevent unidentified groundwater radioactive contamination incidents.
If Yes, whben and to what extent RNP is e.valting site specific risks, plant history, current monitoring practices, and monitoring options to determine the optimal monitoring program.(b,) Does the licensee plan to take other measures to assure they 12 12 can identify radioactive groundwater contamination A
RNP is evaluating site specific risks, plant history, current monitoring practices, and monitoring options to determine the optimal monitoring program.3. Does the licensee have a french drain system surrounding the main reactor facility and auxiliary structures?
RNP does not have a French drain system surrounding the reactor or reactor auxiliary buildings.
There is a French drain beneath the Environmental and Radiation Control (E&RC) building.
This French drain system discharges to the plant storm drain system.The storm drain system that surrounds the plant drains to a retention pond where it is collected and analyzed to liquid effluent lower limits of detection.
This retention pond system is addressed in RNP's Off-Site Dose Calculation Manual (ODCM).(a.) is the system analyzed for radionuclides?(b,)'at what frequency does the licensee sample/analyze the wells The',retention ponds are sampled per the ODCM on a weekly basis.(c.) for what radionuclides does the licensee monitor Gamma emitters (gamma Spec)If Yes -at what MDA The metenlion ponds are analyzed for gamma emitters to the lower limits of detection required by the RNP Off-Site Dose Calculation manualfor liquid effluents.
Tritium If Yes -at what MDA The",etention ponds are also analyzed for tritium to the lower limit of detection requ. -ired by the RNP Off-Site Dose Calculation.
manualfor liquid effluents.
Gross Beta If Yes -at what MDA 4. Does ithelicensee have a surveillance program to periodically: (a.) walk,.wn outside areas around the site to look for potential leaks and pills?RNP has and procedures in place to identify and correct leakage including outdoorareals.
Operations personnel nionitor plant components, equipment, and structures adk.art of their routine rounds. Deficiencies, including leaks, are identified andcorrectl through the site Work Request process aiidlor the Corrective Action Prora(aappropriate).(b.) presiurize buried radwaste lines to evaluate structural integrity and.evw`Srate potential for leaks and spills?RNP performs no generic pressure testing of buried liquid radwaste lines.5. Does the licensee perform any other onsite monitoring (e.g. soil sampling)to identify unexpected radioactive releases RNP quarterly sampling and analysis of the deep well pump effluent used for plant m akeup br tritium and gamma emitting isotopes.
RNP also performs quarterlyý apling and analysis of an artesian well located just downstreani of the Lake RobinIon dam. These samples are analyzed to meet the environmental lower limits of detection for water as described in RNP Off-Site Dose Calculation Manual."I 0 []0 9 Z 0 Ii
- 6. Does the licensee's radioactive liquid discharge line traverse any non-licensee Owned areas (e.g., it is on a right-of-way surrounded by private properties)?
RNP radioactie liquid discharge lines. are within. licensee owned areas.7. If the licefnee has a discharge pipe that runs underground or any undergroubnd piping that carries radioactive liquids, does the licensee perform ,monitoring along the discharge pathway to identify potential leakage.As noted ab ove, RNP has programs and procedures in place to identify and correct observed.leakage.
There is no sampling performed along the RNP liquid discharge piping. Ji If YES, ý.H9ow frequently is the sampling performed:
Phase I (ILonger Term Response)8. Historical .Onsite Radioactive Contamination: (a.) Does the licensee have any history of radioactive spills and/or le ks outside of buildings/structures?
Are they documented in 10 CFR 50.75g file?RNP believes, but is currently verifying that, historical leaks have been documented in the 10 CFR 50.75(g) file.(bP)" Has the licensee identified onsite radioactive groundwater LI C Yes No 0I 0 Yes No 0 LI 0 .][] 0 If YES:,.When was' it identified
-IF known: Dates: LERAbnormal Event Report/Condition Report Nos: (If available)
To what extent -IF known [square footage, estimated ground depth of the contmination, estimated quantity (volume / concentration), etc.]' Has the contamination moved outside the Restricted Area or the owner-controlled area 9. Comments: S.Si
