"Independent Confirmatory Survey of the Nuclear Research Laboratory at the University of Illinois Urbana-Champaign, Illinois" June 2012, DCN 5173-SR-01-0 The following is a response to issues identified in the Summary section 9, pages 13 and 14 of DCN 5173-SR-01-0:

SUMMARY

At NRC's request, ORA U conducted confirmatory survey activities within the NRL at the University during the week of May 7, 2012. The survey activities included visual inspections!

assessments, surface activity measurements, and volumetric concrete sampling activities.

Duringthe course of the confirmatory activities, ORA U noted several issues with the survey-for-release activitiesperformed at the University. Issues included inconsistencies with: survey unit classificationswere not designatedaccording to MARSSIM guidance; survey instrument calibrationswere not representativeof the ROCs: calculationsfor instrumentationdetection capabilitiesdid not align with the release criteriadiscussed in the licensee's survey guidance documents; total surface activity measurements were in excess of the release criteria;and Co-60 and Eu-152 concentrationsin the confirmatory concrete samples were above their respective guidelines."

" .survey unit classificationswere not designatedaccording to MARSSIM guidance:"

The building clearance surveys were a MARSSIM "style" survey. This was not a final status survey and hence was not meant to meet the guidance in MARSSIM. No class I survey was mentioned in the U of I Building Clearance Survey Guidance document because the bioshield (the only *class I" area) was covered by a separate document (UI RX Guidance for Release of Bioshield) which specified 100% scan of the interior concrete surface. (See Attachment 1)

" "survey instrument calibrationswere not representativeof the ROCs;,"

C-14 was suggested as a calibration source for our surface scan instruments instead of Tc-99. C-14 is listed as a Radionuclide of Concern (ROC) only with respect to the Derived Concentration Guidance Limits (DCGLs) for the soil. The default NRC DCGLs were adopted in the Decommissioning Plan wholesale. C-14 is identified in the Site Charactization Report (2005) only with respect to graphite and not general building contamination. C-14 was not considered to be present in any quantity to be a surface contamination problem in comparison with Co-60 and Cs-137. Smear surveys were analyzed in an LSC and no indication of C-14 was present. The Tc-99 check source is

much more representative of the decay energy levels for Co-60 and Cs-137.

S"calculationsfor instrumentationdetection capabilitiesdid not align with the release criteriadiscussedin the licensee's survey guidance documents;"

The survey sheets upon which ORISE made this statement were not the completed sheets.

I am unsure how this occurred. The final sheets have been provided and show the Scan MDC below the surface scan release criteria in all cases. (See Attachment 2)

"total surface activity measurements were in excess of the release criteria;"

Several areas were identified by ORISE as having surface activity above the release criteria. All areas identified by ORISE were remediated and resurveyed to be less than the release criteria. The survey sheets showing the remediated areas and survey points have been provided. (See Attachment 3)

-Co-60 and Eu-152 concentrations in the confirmatory concrete samples were above their respective guidelines. "

ORISE identified four locations from biased samples that showed activity above the release criteria for concrete rubble that are based on a resulting dose of I mrem/yr. These areas were remediated and resampled. Offsite analysis verified that the areas were now below the release criteria. (See Attachment 4)

Guidance for release of Bioshield April 9, 2012 Prepared by: Chris Higgins Radiation Safety Officer Reviewed by: Scott LaBuy LVI Project Manager Approved by: Rich Holm University of Illinois Project Manager

Guidance Release of the Lower Bioshield

==

Introduction:==

Once the upper bioshield and Bulk Shielding Tank (BST) walls are segmented and removed, LVI/ENERCON will begin removal of the internal components of the reactor tank and drain the remaining water from the tank. The result will be an empty aluminum tank about 12 feet deep surrounded by high density concrete more than 7 feet thick in some locations. The bioshield is only 3 feet think on the side of the BST and there is direct access to the tank interior through the two thermal columns and the various beam ports.

With the water gone, the tank interior will be surveyed using hand-held and long-reach survey instruments as deemed necessary to maintain radiation doses ALARA. It will then be removed in sections using appropriate metal cutting techniques to expose the concrete behind the tank wall. A Radiation Work Permit (RWP) will define the necessary radiation protection methods to be used during the tank removal task.

Purpose:

Radiological surveys will initially be performed to assess surface activity, assess the potential for volumetric activation, and to support the planning of work to maintain doses ALARA. Additional decontamination support surveys will be used to evaluate the progress of the removal of activated concrete. Once site health physics personnel believe that all activated concrete has been removed, additional surveys will be performed to confirm that there is a low probability for additional activated or contaminated concrete above the rerelease criteria provided in Table 2.4 of the Decommissioning Plan. This guidance provides the methods for conducting surveys these confirmation Surveys and collecting concrete final confirmation samples from the interior surface of the reactor bioshield.

Applicability:

The guidance below applies to the reactor bioshield concrete walls, concrete making up the base and floor of the bioshield, and the concrete walls and floor of the pipe chase tunnel located below the bioshield. It also applies to metal components embedded within the bioshield wall. These include steel rebar, shadow shields and the beam tubes. Components removed from the bioshield such as beam tubes or shadow shields will be surveyed and released or managed as radioactive waste in accordance with material and equipment free-release procedures.

Release Criteria:

Concrete:

The inner concrete surfaces of the bioshield must conform with the release criteria previously established for detectable surface contamination as well as the volumetric criteria provided in Table 2-4 of the Decommissioning Plan (shown below).

a - The associated release criteria is the invemsc of the 95P percentile dose.

As previously discussed in separate documents including the Decommissioning Plan and a subsequent procedure outlining surface contamination release criteria for clean waste to be released from the NRL, there will be no radioactivity associated with licensed activities measureable on any material released from the NRL as clean waste.

This includes portions of the bioshield that will remain in place for final "clean" building demolition. For concrete surface surveys, the measurable limit criteria equate to about 2

2,500 dprm/100 cm 2 total beta/gamma, about 350 dpm/100 cmr removable beta/gamma, about 16 dpm/100 cm 2 removable alpha, and about 200 dpm/100 cm 2 removable tritium (actual values are dependent on the daily background values).

Shadow Shields, etc.:

Surface contamination release criteria for clean waste to be released from the NRL will apply to shadow shields and other embedded items removed from the bioshield during demolition. There will be no radioactivity associated with licensed activities measureable on any piece of material released from the NRL as 2clean waste. For surface surveys, the criteria equates to about 2,500 dpm/1 00 cm total beta/gamma, 2

about 350 dpm/100 cm 2 removable beta/gamma, about 16 dpm/100 cm removable 2

alpha, and about 200 dpm/1 00 cm removable tritium (actual values are dependent on the daily background values).

Perquisites:

RWPs-wi llbe prepared for removal ofthe alumihnum reactor tank, concrete.'and Oembddedeitem removals (.interiordemoliition),. and interior surveys :and concrete sampling. RWPs will describe proper personnel protective equipment (PPE),

engineering controls, and dose monitoring.

Personnel entering theand interiorspace of the bioshield will wear appropriate fall protectionequipment recovery harnesses if accessing the area from above. If personnel access is by way of the largetherrnal column openinhg fall prqtectiod Will not be necessary.

Calibrated instruments capable of measudrng totalanbd.removable betafgamma are available and maintained in accordance with. ENERCON 'procedures. The University's liquid s-cintillatioh counter (LSC) is available for measuring remoVable H-3 contamination samples.

Sample contaihers and sampling equzipmentare available'fot collecting concrete samples of:50 to100 grams.

Procedure:

1. Cjoncrete blocks removed from the top of the reador showed occasionai low-level surface.contamination onmthe'surface against.the tank wail. Therefore, once.

the alumiunum tank is removed, the initial step Will be to perform a surface

decontamination on thejnterior concrete surface. While initial surface

decontamination will not remove activated 'material, it should 'remove surface cohtamination -thatcould be transfer to other surfaces, equipment, or personnel.

2. LVI ýwill use 'a Brokk robotic tool withaifttached demolition hammers-to rubblize the

,bioshield from the inside.-oUt Periodically demolition will stop for removal of the corncrete rubble. Concrete rubble will be containerized fordisposal As LLRW.

3. At a point when itis believed that most of.the activated concrete has been

removed, surface surveys of the interior will be performe dto assess additional gross' or targeted decontamination/demolifion.

a, Perform a 1 0 0 %/ scan of the,interior concrete sUrface using 2-inch by 2-inch sodium iodide (2x2Nal) gamma scintillation detectors. These detectors will allow'for the delineation of additional areas activated, above the release criteria that wil! require additional targeted removals.

b. ,Micro Shield indicates 'that concrete with ýconcentrations of C-0,or Eu-152. at the criteriavprovided. inr Table 2-4 of t]e Decommissioning Plan, will resulthin an increase of about 1000 counts per mhinutte (cdprm),onb the 2x2.Z Nal detector.

c. Activated concrete samplescollelted in.2005 indicated that the Co-60 ,and Eu-1 52 concentrations were approximately equal (on average)., However, because m0re than".one half-ife.ofG o-60 has:passed since 2065:and"dnly about one--half of an Eu-I 52^ hallf4ife, has passed .the Co-60 concentrations are expected to be about one-half of the Eu-I52' co.ncentratibn.s.

d.. Activated: concrete samples. from 2005: indicpate that Fe-55 is aboutfhalfof the:Co-60 con.centration*.. Due to,the differences'in lthe half-liveS, Fe-55 in, activated 'concrete is expected to be about one-quarter of the Co-60 activity. Given that the Table 2-4 -release criterion for Fe-55 is 10,000 times, the;criteria fo*r-Co-60, 2,2 Nal surveys ihdicating that the Co-60 and Eu-I 52, concentrationsarebelow the Table 2-4 criteria, the surveys will also be indica~ive of the Fe-55 activity concrete being well below.-the Table, 2-4 criteria. The maximum F-55 concentiration rýeported in 13 samplesý was

522,+/-69 -pCi/g.,(decayed to about 100 pC,ilg today-and more than..500.

times.less than the Table-2-4 criterio.m,)

e, Activated cobnredtesample..s from 2005 indicate that Ni-,63 is not present'in measureable amounts,. Thirteen of 13 concretesam-ples analyzed for Ni-63 indýicated that concentrations are :less,than the.-detection imit which Was Jess than 5 pCilg or moretthan 1.000 times le.ss than'.the'Table.2-4 release criterion.

f, Targeted decontaminnation/demolition'may include removing rebar or other

embedded items or:concrete rubbilization.

4. Repeat surveys with,2x2, Nal detectors and targeted remoivals until no. areas of activation are idenitified.

5., Once the 2x2- Nal surveys. indicate that activated concrete.and activated embedded itemshave been removed, a detailed, survey will ýbe:perform"ed using, a MARSSIM-based grid system. Thb survey will include a .100% scan of the intJe'rior of the andsurvey bioshieid and.direct. static measurementsusihg 2x2.Nal de.tectors instruments sensitive to beta/garmma, radiation (iý.e., Geiger-Mueller, gas proportionali, r beta scintillationAdetectors). Static measurement oIcatiodns willbe determined using a random-start grid. Removable;contamination smears Will :also be taken at static measurement ioc.*ations fo.r total beta, and H,3 analysis.

6. AlI2x- Nal measurements should be, indistinguishable from backgroundand beta survey measutements..should, be below the surface contamination releas.e criteria discussed above,

7. Additional biased measurements will be taken on exposed r#ebar. These

-measuremeritswill be noted on the survey form.

8. Gammaarindbeta/gamma surveys, together with prior characterization data, are sufficient to demhonstrate:compliance, with the volumetric'release criteria in Table 2-4 criteria and the surface conrtamination criteria. Therefore, :concrete sampling

will be limited to 6 samples collected from six different direct measurement locations. Each sample will be analyzed by an off-site laboratory by gamma spectroscopy for gamma-emitting isotopes including Co-60 and Eu-1 52 and by liquid scintillation counting for H-3, Fe-55, and Ni-63. Minimum detectable concentrations should be less than 50% of the Co-60 and Eu-I 52 criteria and less than 10% of the H-3, Fe-55, and Ni-63 criteria.

9. An additional 2 rebar samples will be collected from two separate locations that received direct survey measurements. These samples will be analyzed as described above. However, H-3 analysis is not required.
