EXECUTIVE SUMMARY
Omaha Veterans Administration Medical Center
NRC Inspection Report 50-131/96-01
This routine, announced inspection reviewed the reactor operations, reactor maintenance,
surveillance testing, experiments, reactor oversight, reporting, reactor operator
requalification, radiation protection, emergency preparedness, and security programs.
Operations
Reactor operations were conducted well. The reactor operator was knowledgeable
of routine operating procedures. No safety limits or limiting conditions for operation
of the reactor were exceeded. Experiments were reviewed appropriately and
performed safely (Sections 01, and 04).
Standard operating procedures generally provided adequate guidance to ensure that
operations and surveillances were conducted properly and consistently. However, a
violation was identified involving the lack of written standard operating procedures
for some surveillance activities (Section 03).
A Non-Cited Violation was identified involving the failure to include all required
i
topics in the annual operating reports (Section 01).
The operator requalification program was conducted as required (Section 05).
Adequate oversight of reactor operations was provided by the Reactor Safeguards
Committee (Section 07).
Facility Suncort
Appropriate radiation protection practices were implemented. Minimal radiation
hazards were present with the reactor operated as observed (Section R1).
A good emergency preparedness program was maintained and the physical security
plan was properly implemented (Sections P1 and S1).

01
Conduct of Operations
a.
Scope of Inspection
The inspector interviewed a senior reactor operator and reviewed the following:
'
>
Reactor logs
l
Annual operating reports for 1993-1995.
!
b.
Observations and Findinos
The reactor normelly operated at a steady-state power level of approximately 18 kilowatts.
Reactor power levels did not exceed the limiting condition of Technical Specification 3.1.
Reactor use declined steadily since 1993.
r
Seven unscheduled reactor shutdowns occurred in 1993, three in 1994, and two in 1995.
l
The majority of the unscheduled shutdowns were caused by electrical noise or electrical
'
power interruptions.
The major maintenance activity involved a repair of the pneumatic sample transfer system.
A new fuel element was installed in the reactor in October 1995.
The required technical specification surveillance tests were conducted.
Four new experiments were added since the previous inspection. Experiments 94-1
through 94-4, were reviewed and approved by the Reactor Safeguards Committee, in
accordance with Technical Specification 6.8. The reactivity worth of the experiments did
not exceed the limit of Technical Specification 3.6. Samples which were irradiated met the
requirements of Technical Specification 3.7. No unreviewed safety questions were
identified.
Technical Specification 6.9.1.2 requires, in part, that each annual operating report include
a brief narrative summary of major surveillance tests and inspections. The only
surveillance test discussed in the 1994 and 1995 Annual Operating Reports was the fuel
inspection surveillance. Other surveillances were not discussed. Technical Specification 6.9.1.2 also requires that each annual operating report include a brief
description of any new or untried experiments or tests performed during the reporting
period that are not described in the Safety Analysis Report. The 1994 annual report did
not include a discussion of the Experiments 94-1 through 94-4. The inspector identified
the omission of these items from the annual operating reports as a violation of Technical
.
4
I
!
Specification 6.9.1.2 (131/9601-01). This failure constitutes a violation of minor
.
significance and is being treated as a Non-Cited Violation, consistent with Section IV of the
NRC Enforcement Policy. The licensee acknowledged the inspector's comments and
stated that the requirements would be reviewed to ensure all necessary inforrnation was
included.
l
c.
Conclusions
'
Reactor operations were conducted well No safety limits or limiting conditions for
opvation of the reactor were exceeded and required surveillances were performed.
Experiments were reviewed appropriately and performed safely. The annual operating
reports did not comply with all documentation requirements.
O3
Operatior.s Procedures and Documentation
a.
Inspection Scope
l
The procedures listed in the attachment were reviewed.
l
b.
Observations and Findinas
'
I
Procedure 16, " Conduct of Irradiations and Experiments" was the only procedure added
,
since the previous inspection. The procedure was approved by the reactor supervisor, as
required.
Technical Specification 6.7 requires, in part, that there shall be written procedures that
cover the surveillance, testing, and calibration of instruments, components, and systems
involving nuclear safety. The inspector identified that standard operating procedures were
available to provide guidance for conducting some surveillances, but not others. Although
the surveillance activities were conducted correctly at the proper frequencies, no
procedures were available to provide guidance and ensure consistency for nuclear safety
systems involving the measurement of scram times (required by Technical Specification 4.2.2(1)), testing of pool level channel operability (required by Technical Specification 4.2.2(2)), and verification of ventilation system operability (required by Technical Specification 4.2.4). The inspector identified the lack of written testing and surveillance
procedures as a violation of Technical Specification 6.7 (131/9601-02).
c.
Conclusions
_
Standard operating procedures generally provided adequate guidance to ensure that
operations and surveillances were conducted properly and consistently. However, this was
not true in all cases, and a violation was identified because standard operating procedures
were not implemented to provide guidance for some surveillance activities involving nuclear
safety systems.

Section 3.c. of the licensee's Requalification Program for Licensed Reactor Operators
stated that information should be included in on-the-job training so that each licensed
operator and senior operator is cognizant of facility design changes, procedure changes,
and facility license changes. There was no documentation of a discussion concerning the
implementation of Standard Operating Procedure 16. The procedure was implemented

since the previous inspection. However, the senior operator was knowledgeable of the.
procedure, so the inspector concluded that the on-the-job training functioned appropriately.
,
,
A review of the abnormal / emergency procedures was conducted. Annual written
examinations for 1994,1995, and 1996 were given and successfully passed by the senior
reactor operator.
c.
Conclusions
The operator requalification program was conducted as required.

Operations Organization and Administration
The inspector reviewed the licensee's organization and determined that no changes had
been made in the structure of the organization, and it continued to be as described in
Technical Specification 6.2. Since the previous inspection, the only personnel change
involved the radiation safety officer. A new individual was hired to fill the position. The
licensee had two senior reactor operators, one of whom was the reactor supervisor. There
were no reactor operators.

The following documents were reviewed:
Annual review of radiation protection program
Annual radiation dose summaries for 1993 1995.
.
Radiation surveys in reactor log books
Weekly contamination surveys
Instrument calibration records
b.
Observations and Findinas
Annual reviews of the radiation protection program, in accordance with 10 CFR 20.1101(c), were performed in conjunction with the annual reviews of the medical center
broad license radiation protection program.
Reactor operators used extremity monitoring in addition to whole body dosimetry. The
'
extremity monitoring was used to record the dose accrued by the operators when they
handled irradiated samples. Most dosimetry results were minimal. The limits of 10 CFR 20.1201 were not exceeded.
The inspector performed area radiation surveys and confirmed that radiation levels in
unrestricted areas did not exceed the limits of 10 CFR 20.1302(a)(2)while the reactor was

operating at a power level of 18 kilowatts. The licensee had survey records and area
dosimetry monitoring results as documentation of its radiation measurements. Restricted
areas were posted in accordance with 10 CFR 20.1902. The licensee also performed
general area contamination monitoring weekly.
Calibrations of the instruments used to perform radiation surveys were performed with
radioactive sources traceable to national standards. Calibrated instruments were available
at the time of inspection.
Workers were provided radiation safety instruction by the reactor supervicor in accordance
with 10 CFR 19.12.
The inspector determined that the licensee had not transported radioactive materials since
the previous inspection.
The inspector reviewed the licensee's program of material control and accountability to
determine compliance with license conditions and 10 CFR Part 70.
The inspector reviewed material balance and inventory records and determined that the
records were properly maintained in accordance with the requirernents of 10 CFR Part 70
and that the licensee did not exceed the uranium-235 possession limits of License
Condition 2.B.(2). There had been one receipt of fuel since the previous inspection.
Receipt of the material was properly documented. The material was properly stored,
c.
Conclusions
Appropriate radiation protection practices were implemented. Minimal radiation hazards
were present with the reactor operated as observed.
