Followup on Previously Identified Inspection Findings (Closed) Violation (112/8701-03):

Failure to Provide Emergency Response Yraining - This violation was identified in NRC Inspection Peport 50-112/87-01 and involved the failure to provide training in radiation safety and the facility emergency procedures to individuals from the Norman Fire Department who would respond to an emergency at the facility.

The licensee provided training on radiation safety to 13 members of the Norman Fire Department during the period of September 11-15, 1989.

(Closed) Violation (112/8901-01):

Authority to Dismantle a Facil_ty -

i This violation was identified in NRC Inspection Report 50-112/89 Sl~and involved the dismantling of the University of Oklahoma research reactor facility prior to submitting a decommissioning plan and obtaining NRC approval. The NRC, on June 5, 1989, issued an order authorizing dismantling of the facility and disposition of component parts.

(Closed) Violation (112/8901-02):

Reactor Safety Committee Composition -

This violation was identified in NRC Inspection Report 50-112/89-01 and involved the lack of a reactor safety committee and reactor director.

The NRC, on June 5, 1989, issued an order authorizing dismantling the facility in accordance with the application dated October 25, 1988, as supplemented.

Appendix A to the NRC order contains the facility Technical Specifications and does not require a reactor safety committee.

(Closed) Violation (112/8901-03):

Reactor Safety Committee Mestings -

'

This violation was identified in NRC Inspection Report 50-112/b9-01 and involved the failure of the reactor safety committee to conduct semiannual

.

meetings.

The NRC order, of June 5, 1989, does not require a reacter i

safety committee or any scheduled meeting frequency.

-(Closed) Violation (112/8901-04):

Reactor Safety Committee Audits - This violation was identified in NRC Inspection Report 50-112/89-01 and i

involved the failure of the reactor safety committee to perform the

~

' required audits of activities related to the reactor license conditions.

The NRC order, of June 5, 1989, does not require a reactor safety committee or any scheduled audits of the reactor license conditions.

I (Closed) Violation (112/8901-05):

Emeroency Response Training - This violation was identified in NRC Inspection Report 50-112/89-01 and involved the lack of emergency response training for the Norman Fire Department.

This was a repeat violation (112/8701-0*>).

The licensee had provided radiation safety training for 13 members of the Norman Fire

>

Department during the period September 11-15, 1989.

Release Criteria for Unrestricted Use

'

The radiation levels for release of the reactor facility for unrestricted use were established in " Safety Evaluation by the Office of Nuclear

'

Reactor Regulation Dismantling of Facility and Disposition of Component

Parts Research Reactor Facility (AGN-211P) Facility License No. R-53 Docket No. 50-112" and supporting NRC order, dated June 5, 1989.

The safety evaluation states that surfaces must be decontaminated to levels consistent with Table 1 of Regulatory Guide 1.85, " Termination of Operating Licenses for Nuclear Reactors." In addition, external exposure rates must be less than 5 micro Roentgens per hour (pR/h) above natural background at 1 meter from the measured surfaces or that no person will receive more than 10 mrem / year.

Natural background had been defined as radiation from naturally occurring radioisotopes as measured at a

comparable uncontaminated structure or exterior soil surface.

,

4.

Disposition of Material

.

.The reactor has been dismantled and the fuel has been transferred to Martin Marietta Energy Systems, a Department of Energy (DOE) contractor.

,

Records maintained by the licensee indicated that radioactively contaminated components had been transferred to the University of Oklahoma Byproduct License (35-07466-05) for disposal via its low-level radioactive waste program.

The radium-beryllium neutron source has not been-transferred to any facility for disposal.

The licensee is working with

= the State of Oklahoma and DOE to dispose of this source.

This source is not licensed by the NRC.

A review of DOE /NRC Form 741 indicated that the fuel was transferred and shipped to Martin Marietta Energy Systems on April 30, 1988, and an acknowledgement was received.on May 10, 1988.

No violations or deviations were identified.

5.

Records of Personnel Exposure The licensee had issued personnel exposure monitoring devices, thermoluminesent dosimeters and direct reading dosimeters, as part of the University of Oklahoma's radiation safety program.

This program is administered by the university's radiation safety office.

Records of personnel exposures are being maintained by the university.

The licensee had not provided bioassay sampling and analysis as there was no recorded

incident which would have suggested that an internal uptake of radioactive

material had taken place and necessitated the need for such monitoring.

No violations or deviations were identified.

Licensee's Termination Survey Report

'

L The. licensee submitted the " Dismantling and Decommissioning Activities for the University of Oklahoma AGN-112P Nuclear Reactor Facility Docket

,

No. 50-112" on August 28, 1989.

This report summarized the results of

,

! :.

surveys and decommissioning activities in the decommissioning log book

~

during the period of May 18, 1988, through August 1989.

The inspector reviewed the decommissioning log to determine if radiation surveys and surface contamination levels were in agreement with the values specified in the dismantling plan and NRC guidance.

No violations or deviations were identified.

7.

Independent Confirmatory Measurements The inspector performed a verification survey of the Nuclear Engineering Laboratory Building, Room 107, Reactor Laboratory.

This survey was performed to independently verify that the reledse criteria for unrestricted use, described in paragraph 3 above, was fulfilled.

The radiological surveys performed included direct measurements of beta and

,

gamma exposure rates.

Measurements of removable (transferable) and nonremovable alpha and beta contamination were also made.

All components

,

had been removed from the reactor.

As a result, the inspector had easy

"

access to the empty reactor tank and east and west storage pits.

The inspector determined that the general background direct gamma radiation levels associated with the facility were 9-14 pR/h.

The

-

inspector also verified that the maximum residual radiation levels were not greater than the general background level.

No localized or activated

" hot spots" were identified.

In addition to gamma measurements, the inspector also performed surveys to identify fixed alpha and beta

,

radiation levels.

No alpha or beta radiation levels above the general

~

background were identified.

The inspector performed surveys to identify removable alpha and beta contamination using conventional paper smear techniques.

Smear surveys were taken over a nominal 100 square centimeters (100 cm ) and analyzed

for alpha and beta disintegrations per minute (dpm/100 cm ).

No removable i

radiation contamination levels above background levels were found.

The specific details concerning the radiation surveys are documented in Attachment 1.

No violations or deviations were identified.

Reactor Components The inspector surveyed the reactor components such as control rod drives, j

reflector elements.-core support item 3, and experiment transfer tubes.

These components had been removed from the reactor tank and held in temporary storage'in the west storage _ pit.

Surface gamma radiation levels of about 5-20 pR/h above background were found on a bolt in the tip of 27 reflector elements.

Fn110wup analysis by the licensee identified that the bolts contained cobalt-60.

Smear surveys were performed on the elements; no removable contamination was found.

The gamma radiation levels appeared to be the result of activation of the cobalt metal in the bolts in the reflector elements.

All reflector elements that indicated radiation levels above background were segregated and' transferred to the University's byproduct license for accountability purposes.

'

No violations or deviations were identified.

9.

Exit Interview The inspector met with the licensee representatives denoted in paragraph 1 of this report at the conclusion of the inspection on October 11, 1989.

conduct surveys of the entire _ reactor facility.

Some radiation level above general background were I

present due to the storage of sealed calibration sources (Cs-137) and a critical assembly.

However, no radiation levels were found that were the result of reactor operations.
