1.0 INTRODUCTION

This document summarizes the available information concerning the decomissioning of the NCSUR-3 (R-3) reactor located at North Carolina State University. This small research and training reactor is similar to a number of others presently in use ur in a shutdown status throughout the U.S.

The decision was made to decomission the subject reactor in the DECON mode in order to free the occupied space for other university-associated activities.

The decomissioning data were assembled in a form that~ permitted its input .i' into a computerized data-handling system. The computer program used is a flexible data accumulation, manipulation and retrieval system which can provide:

e Greater accuracy in cost, labor and radiation exposure estimates e Greater awareness of methods for keeping radiation exposures ALARA e Guidance in estimating time requirements for decommissioning activites '

e Better prediction of radiation and contamination levels e Identification of special areas of difficulty in the decommissioning process.

As the amount of data fry.n actual decommissioning projects increases,-the value of the Decomissioning Data System as a decommissioning aid is enhanced. Some comparison information with reference research and test reactors is included in Section 2.0.

3.0 DESCRIPTION

OF COMPUTER REPORTS ,

The reports described below are the basic reports used in the decomissioning data system (DDS). The' descriptions, as presented, are intentionally idealized. - It should be understood that all report functions will not always be utilized, because the available decommissioning information varies from project to project. In addition to the basic reports, the MAPPER computer program used'as the basis for the DDS provides the ability to produce supplementary reports by manipulating the data available in the basic reports.

3.1 General Information ,

This report is a free format input report designed to accommodate descriptive data of any kind. - Entries may be given any title and related to any facility system by a' system component number. Data are entered in any fonnat on any subject. The report is used to record information that does not fit into any of the report types organized by column. This includes facility 1ccation, descriptTon, owners, operators, builders, etc. Summary data may also be included where it is not readily derivable from other reports or for convenient reference.

3.2 Decommissioning Code Table /Index This report contains a list of unit items, including facility buildings, systems and system components, and budgetary items, with a corresponding identification number for each unit. The identification system is used througSout'DDS to relate data to specifically identified units.

This basic report type may be expanded to include tables or indices of other

-kinds related to facility decommissioning. Candidate tables are labor L category wage rates, shipping company rates, shipping company name codes, disposal site name codes and rates, or archived file tape names.

One of the basic values of this report is the fact that, by utilizing an index which can ultimately be made common to all reactor facilities included in the program, the report can become the intercomparison base for the DDS.

The full utilization of this base will not be possible until an adequate number of facilities are included in the DDS.

3.3 Significant Event Report This report is used to record the f acility's operating history, which in some cases could impact facility decommissioning. It contains dates,

^

system / component numbers, and event descriptions. Noteworthy events such as construction completion, startup, shutdowns, significant incidents, and-accidents are recorded in this report.

i

[-

3.4 'Radionuc1ide' Inventory "

In inventory of radionuclides present in each facility system will be made

- prior to the start of decommissioning'. The amount of each radionuclide-or its conce'ntration, the measurement. date, and a description of each system's.

material- composition is recorded. . It is- also noted whether a radionuclide present in ta system is the. result' of neutron activation or. contamination.

3.5 - Project Cost / Exposure Report Costs, schedules,_-man-hours, man-rem, both estimated and actual, are listed for each activity specification! number.- :These costs may be broken out on lines having a subactivity specification number. This report is the main respository of cost and exposure information for a decommissioning project.

3.6 _ Dose Rate and-Contamination Report ,

Dose rates at locations throughout each facility are recorded p' rior to decommissioning. Locations relative to a reference map, elevation, system / component number, and type of measurement are recorded for each measurement. lBoth upper and lower limits of dose rates or contamination levels (in disintegrations per minute) are listed. ,

3.7 ' Project Labor Report Decommissioning labor costs, exposure, and man-weeks for each activity specification are recorded at a to-be-determined frequency. This ,

supplements the project cost / exposure report by providing data on how costs and exposures accumulate over the course of. a decommissioning project.

- 3.8 ALARA Report.

The ALARA report contains records of ALARA efforts by activity specification-number. The affected facility system,-date, cost items. exposure

. information, and a description of the ALARA effort are listed. This report can be used to calculate by activity specification number or for all activities the total estimated man-rem saved as well as total cost incurred

- through the implementation of the ALARA effort.

3.9 Shipment Report Volumes, weights, and other physical data are recor.ied by waste type for material produced by eact activity specification. These data are listed for each shipment of material from the decommissioning site. Trip lengths and-vehicle dose rates are recorded'in order to calculate public e sposure.-

3.10 Disposal Costs The costs associated with each waste disposal shipment are recorded in the Disposal Costs Report. Costs are divided into transportation, burial, and container categories. Costs for each container type on the shipment are also listed..

3.11 Surveillance Report The surveillance report is used to record annual costs and exposures associated with long term surveillance of a decommissioned facility. Under normal conditions a surveillance report would not be included for a facility decommissioned under Mode DECON.

3.12 Public Dose Report The exposure of the public to radiation which results from the decommissioning of nuclear facilities is one criterion which is to be considered during the pre-decommissioning evaluation phase. This report presents an estimate of such exposure information, based on extrapolations of measurement data and numerous assumptions, including both routine and accident conditions.

1983 data are interim estimated.

LIn planning for large decommissioning projects which cover long time spans or are scheduled to start at some time in the future, cost estimates should consider the " worth" of current money-and then adjust cost estimates to reflect this consideration. This exercise, referred to as a " time'value cost analysis", considers the year of expenditure, interim surveillance and maintenance costs, major non-routine maintenance costs, and inflation rates. " Worth" of current money is usually based upon an average yield on stable, non-speculative investments such as long and short-term treasury bills. - A " time value cost analysis" results in a percentage value, referred to as the discount. rate, which is used to discount the ~ cost of a future project to the current " worth" of money. This discount rate includes consideration of financial uncertainties, such as project cost overruns, recovery costs for major accidents, etc.

Example - A discount rate of two percent yields the following table:

, Discount Discount Year Factor Year Factor 1 0.9804 6 0.8880 2 0.9612 7 0.8706 3 0.9423 8 0.8513 4 0.9238 9 0.8535 5 0.9057 10 0.8204 i If project is estimated to cost $10,000 during a time period six years from today, the arount of money presently required to be invested is ($10,000)

(0.8880) or '48,880.

l5.0. FINAL SITE CONDITION .l 1

, /5.1:' Criteria-L The decommissioning contractor :left_ the R-3 Bay'in an acceptably clean.

condition'on. March 7, 1983. The North Carolina State University Health Physicist then: began the final site survey to' assure thattthe= dismantling work ~had resulted in satisfactory decontamination 'of:the R-3 bay. The

~ Nuclear. Regulatory Comission had required that the _ dose rates at one meter due to the activity of Cs-137, Co-60,'and Eu-152 be less than.25 UR/hr-(5

- pR/hr above the 20 pR/hr background).1 . Regulatory Guide-1.86 recommendsthat

'he removable contamination be less-than 100 disintegrations per. minute-per L100: square centimeters. The philosophy of-the NCSU final site survey was to .

take dose rate surveys .and removable contamination = swipes-of all existing-surfaces in the R-3 Bay at ten -(10); foot intervals to assure satisfactory-

--decontamination to levels below the Regulatory Guide 1.86 recommendation.

5.2 Final Site Condition 5.2.1-.NCSU Final Site Survey '

All-horizontalfsurfaces were surveyed _~and swipediin the survey. .These.

surfaces included the radial trenches, fuel storage bins and the base and-foundation of the R-3 as the contractor left it. 'The beam catchers and :.-

storagelholes in:the wallsi.were'also swiped. In practice, the ten (10); foot' interval was reduced to eight- (8) f_eet to better fit the geometry of the R-3 l Bay. The R-3 Bay walls were'also surveyed and swiped up to the level of the F crane track.-

The dose ~ rate surveys showed that all areas-in the-R-3 Bay were ,

. decontaminated to a level:of less than 25.pR/hr except the area directly above the concrete which was below the R-3 core.- Thisulocation appeared to measure between 26 and 27-pR/hr with a Ludlum pR/hr meter. All of the swipes taken~showed removable contamination of less than 85'dpm/100 cm2.'

The results of the NCSU HP Final l Site' Survey were incorporated in a letter to the NRC dated March 29, 1983.

5.2.2 Confirmatory NRC Survey The licensee (NCSU) submitted their report of'the final survey of the R-3' reactor: facility for radiation 'and' radioactive material to the Nuclear n Regulatory. Comission on March 29. 1983.- Residual removable contamination L levels were far below the limits for release fer' unrestricted use. The survey report -showed that in one area the external. radiation levels at one .

- meter above the floor were 7;to 8 pR/hr'above a background:of 20 pR/hr. i This location was.one meter above the floor'in the center of the facility below the reactor core locat. ion after approximately le inchas 'of' concrete l'

inspector, utilizing 1-1/2 inch thick steel plat'e to simulate the shielding regained by replacing the removed: concrete and to re-establish the floor level. Subsequent measurements, both with and without the steel plate in place, were less than the required 5 ER/hr. above a background of 20 ER/hr.

T'h e assumption is made that replacement of the removed concrete will reduce the radiation levels to below those permissible for unrestricted use.

Smear surveys by the NRC inspector'showed removable contamination levels were well below the release limits for unrestricted use. The smears were counted for both alpha and beta / gamma activity at the licensee's facility.

Confirmatory beta measurements were made in the Region II laboratory.

Thirty disintegrations per minute (dpm) per 100 square centimeters (100 cm2) was the highest beta / gamma level. The highest alpha level was 1.9 dpm/100 cm2, The inspector had no further questions or comments.

6.0 CONCLUSION

S AND LESSONS LEARNED Several lessons were learned from the decommissioning of the R-3 reactor which might be helpful to others. These lessons are sumarized in the following paragraphs.

6.1 As-Built Drawings Throughout the life of the f acility, a complete set' of '"as-built" drawings and manuals should be maintained. Such "as-builts" should include embedments in the structure even though they are no longer used. In fact, it would be advisable to maintain a set of drawings that shows every permanently installed fixture that must ultimately be removed everi though it is no longer in use.

6.2 Modifications to the Structure l- Any modifications to the structure should consider ultimate dismantling. To L allow grout or a bonding agent to flow into the crack between otherwise

! indepenoent concrete strec' es could make them far more difficult to l remove. Also to reduce d' antling costs, buildings containing large steel l structures should have lars e doors or other provisions to allow intact j removal of large pieces of equipment.

6.3 Disassembly Tools Disassembly tools should.be cMatae%d in a storage space with controlled eccess. Special tools may have been designed to ' install certain parts of the structure and components. If;these tools are seldom used, then they may be -last. A good example of this were four (4) eye bolts that were used for remcving a several-ton concrete block from the R-3 reactor. Without these i

eye bolts, it would have been necessary to use a jack hammer to break up the

- concrete and remove it in pieces. The eye bolts were threaded to match the

. i

- threads of an embedment which were non-standard. . Fortunately, a piece of-one'of the~old eye bolts was . located and from that. piece it was possible to remanufacture four (4)~ eye bolts that would: fit-the embedments.

i:

l 6.4 ? L' abor Productivity

' ~

Labor productivity ~ should take into account orientation time, high turnover rates among' laborers assigned to.a tjob,.and the time' required to suit up to

enter a controlled area.; The_ contractor' hired by NCSU to dismantle the

. ' concrete ' structure had no experience working his men under the controlled . .

conditions required in a nuclear < facility. Consequently, labor productivity-

was.less than predicted.

6.5 Prepare the Decommissioning Plan and Maintain it Up-to-Date The Decommissioning Plan _should be prepared with assistance from the Operation and Maintenance staff 'during the early. years of plant operation.

It should be-reviewed prior to major modifications to-the facility and 4

revised following the modifications.

6.6 Use Existing-Staff >

Use existing Operations.and Maintenance staff for the initial phase of the

' dismantling. This will-allow the plant staff to compare the condition of the plant.at the time of decommissioning with "as-built" drawings. This '

l ~ effort should. produce. information that would allow a' contractor to more intelligently prepare a proposal for the decommissioning l work.

4 6.7 ' Dust Control -

r

' If the concrete structure is to be broken up, dust control must be c

. thoroughly studied. It is recommended that ths first concrete to be broken

-up should be non-radioactive. During the first few days of the demolition of the concrete structure of -the R-3 reactor, -fine dust was distribeted throughout a three-story research building. Decoatanination would have been extremely difficult if this fine dust had been radioactive. Awareness of L this . problem and the possible ' consequence: of the spread of contamination -

throughout the. building, caused the contractor to. improve the ventilation system for dust control. -

_ 6.8 Keep the Nuclear-Regulatory Commission Informed

- The huclear Regulatory Commission has not-yet developed a complete set of ,

guide!1res for the decommissioning of nuclear facilities. Where guidelines

< do 4xist, they do not refer specifically to research reactors. Discussions

with Nuclear Regulatory' Commission personnel'in Bethesda, Maryland and Atlanta, Georgia were most helpful.

The decommissioning data were placed in a computerized information retrieval / manipulation system which permits future utilization of this information in pre-decommissioning activities with other university reactors of similar design. The information is presented both in some detail in its computsr output form and also as a manually assembled sumarization which highlights the more significant aspects of the decommissioning project. Generic. decommissioning data extracted from NUREG/CR 1756, " Technology, Safety and Costs of Decommissioning Nuclear Research and Test Reactors," and data from the decommissioning of the Ames Laboratory Research Reactor (ALRR),

a 5 MWt research reactor, is also included for comparison.
