Portland General Electric Concordia University Reed College operates a Triga Mark I reactor with zirconium hydride/uranium hydride fuel elements. The fuel elements are in a circular grid array at the bottom of a 25-foot-deep tank of water and are surrounded by a graphite reflector. The fuel is enriched to 19.9% in uranium-235.

The Reed College Research Reactor has been a resource for research and educational projects in the Portland area since its establishment in 1968. The main uses of the Reed Research Reactor are instruction and research, especially in the field of trace-element analysis. In addition to providing student research opportunities, the reactor staff works to educate the surrounding community on the principles of nuclear energy and radiation safety.

There were 2827 individual visits to the Reactor Facility during the year. Most were students in classes at Reed College or area universities, colleges, and high schools.

Including tours and research conducted at the facility, the Reed Research Reactor contributed to the educational programs of 12 colleges and universities in addition to 12 pre-college groups and 4 special groups. The reactor was operated 377 times on 137 days.

The thermal energy produced was 22.71 megawatt-hours.

The reactor staff consists of a Director, an Associate Director, a contract Health Physicist, Reed College undergraduate students, and a few non-students who are licensed by the Nuclear Regulatory Commission as reactor operators or senior reactor operators. As this Reed Research Reactor Annual Report 2004-2005 . Page 7 of 40

I I-report is being written the licensed operating staff consists of 21 women and 27 men.

Reactor Facility  ;

In addition to the reactor, the Reed Coliege hfas'space for a radiochemistry lab. The equipment available at the reactor facility includes'high purity' germainium gamma spectrometers, an X-ray florescence detector, surface barrier detectors, alpha spectrometers, silicon lithium X-ray detectors, a whole body counter, gas flow pr6p6rtional counters, ion chambers, beta counters, Geiger Muller tubes, neutron detectors, alpha detectors, and thermo luminescent dosimeter readers. These instruments are used for experiments and training in nuclear science and radiation detection; vTwo hand and shoe monitors are in the reactor bay.

A liquid scintillation detector serves the campus radioisotope committee. The reactor facility has several systems for performing irradiations, described below.;

Rotating Specimen Rack Facility -

• Therotating specimen rack ("lazy susan") is located in a well on top of the graphite reflector surrounding the core. The rack consists of a circular array of 40 tubular receptacles, each of which can accommodate two irradiation tubes. Vials holding up to 17 ml (four drams) are used in this system. Samples are loaded in the specimen rack prior to the start-up of the reactor. The rack automatically rotates during irradiation to ensure each sample receives the same neutron flux. Typically, researchers use the rotating rack when long irradiation times (generally greater than five minutes) are required. The approximate thermal neutron flux in a rotating rack position at full power is 1.7 x 0' 2 n/cm s with a cadmium ratio of 6. The specimen rack can be used for gamma irradiations (approximately 8 Rad/min) when the reactor is shutdown.

Pneumatic Transfer System The pneumatic transfer system ("rabbit") consists of an irradiation chamber in the outer F-ring of the core and its associated pump and piping. This allows samples to be transferred in and out of the reactor core very rapidly while the reactor is at power.

Routine use of the pneumatic transfer system involves placing samples into vials, which in turn are placed in special capsules known as "rabbits." The capsule is loaded into the system in the laboratory next to the reactor and is then transferred pneumatically into the core-irradiation position. At the end of a predetermined time the sample is transferred back to the receiving terminal, where it is removed for measurement. The transfer time from the core to the terminal is about seven seconds, making this method of irradiating samples particularly useful for experiments involving radioisotopes with short half-lives. The flux in the core terminal is approximately 5x10'2 n/cm2 s when the reactor is at full power.

In-Core Facilities The central thimble is a water-filled irradiation chamber about 3 cm in diameter. It provides the highest available neutron flux, about Ix I0'3 n/cm 2 s. Special sample holders are used in the central thimble to provide maximum flexibility in experiment design.

Reed Research Reactor Annual Report 2004-2005 Aag 13 of 40

A fuel replacement source holder assembly can also be used as an irradiation facility. The chamber fits into a fuel-element position within the core itself. It holds only one specially positioned irradiation container 7.5 cm in length and 2.5cm in diameter.

Foil-insertion holes, 0.8 cm in diameter, are drilled at various positions through the grid plates. These holes allow inserting special holders containing flux wires into the core, to obtain neutron flux maps of the core.

In-Pool Facilities Near core, in-pool irradiation facilities can be arranged for larger samples. Neutron fluxes will be lower than in the lazy susan and will depend on the sample location.

An iridium gamma irradiator is also in the reactor pool for gamma only irradiations.

Beam Facilities The central thimble can be evacuated with gas, producing a vertical neutron beam. This beam can be used to generate directional neutron flux, or for limited irradiations above the tank.

Prompt gamma analysis and neutron radiography can be done. The flux above the beam exit is approximately lx 106 n/cm2 s when the reactor is at full power.

IIUSERS Reactor Visitors A total of 2827 individuals visited the Reed Research Reactor during the year, as derived from the visitor log - Entry List B. Individuals who visited more than once are counted for each visit. Visitors include all individuals who are not listed as facility staff. The visitors included 1965 individuals for training or tours, of whom 835 were in programs funded in part by the U.S. DOE Reactor Sharing program. A large percentage of these were students in classes at area colleges and schools as discussed below. A graph of the history of visitor attendance is shown in Figure 1, and a list for the current year is included as Appendix A.

• ia -isosu t fro Ree and The Reed Research Reactor conducts an annual seminar seies for students from Reed and other area educational institutions. This non-credit course serves as ah introduction to nuclear reactor theory, health physics, and reactor operation: Some of the students continue with in-depth reactor operator training and subsequently apply for a reictor operator license.

If successful, the individual may be hired to operate the reactor. In addition, existing reactor operators may take the NRC senior reactor operator exam to upgrade their licenses.

During the reporting period, 21 out of 22 reactor operator candidaies passed their NRC exams and I I out of II senior reactor operator candidates pas'sed their NRC exams.

Historically students who fail the NRC exam only fail one section and they'are allowed to retake that section later. Figure 2 is a graph of the number of license application each year

A typical lab involves determining the background of a Geiger Muller scalar system and then determining the half-life of a sample of radioactive material. College classes are generally more closely tailored to the individual interests and needs of the Consortium faculty member involved. Experiments include more direct use of the reactor itself by the students, more detailed analysis of materials, and emphasize the incorporation of other classroom activities as much as possible.

Several special programs for gifted children use the reactor for projects. These are designed to enrich their educational program and prepare them for college. Some of the groups who Reed Research Reactor Annual Report..2004-2005 P.4 17 of 40

use the reactor target minority and disadvantaged youth who are historically under-represented in science professions...

High School Student Projects The Reed Research Reactor continues to be used in independent science projects initiated by students from several OregonandWashington State high schools.

Pacific University Modern Physics Lab, Each year the Modem Physics Lab.~at Pacific University spends lab sessions at the reactor.

The students do several labs including basic health physics, sub-critical multiplication, and neutron activation analysis.

Concordia University The reactor provides training and experiments involving radiation, radioactive material, environmental sampling, and trace element analysis for the Environmental Remediation &

Hazardous Material Management Program (ERHMM) and General Chemistry at Concordia University Scaler Kits Through the generosity of Portland General Electric; the reactor lends out kits containing a Geiger counter, a scaler, and some small exempt sources to local high schools for their use in their Advanced Placement Physics Class. '

Reed Classes

• Chemistry 271 students used neutron activation analysis to determine chemical composition of an unknown compound.

• Chemistry 101 students determined the half-lives of an activated silver dime.

• Two Reed students used the reactor as part of their thesis.

Industrial and Commercial Applications The Reed Research Reactor is available for industrial or commercial concerns when it does not conflict with our educational goals. As in the past, the primary operations involved neutron activation analysis of materials or environmental samples. The facility also provides radiation protection training to interested parties and schools in the area.

Gamma Irradiations in VPool i l Date: November 8, 2004 .  ; . . -:

• Summary of Proposed Chance: .  ; ' .: ' !i.

This change all)6Ns gamma irradiations in the pool. This is one of the original irradiation methods contceived when the facility was built; but no routineex'perirent or procedure

'waswritteff& it. * ' 1 *:

Often experiments require a gamma flux but no neutron flux because the purpose of the

• experiment is exposure to gamma radiation, not activation. These are currently accomplished by.loading the sample into the lazy susan while the reactor is shutdown.

!.The gamma flux in the lazy susan,varieswidely with time since shutdown, from approximately 3 Roentgen per minute to 8 Roentgen per minute. Also, shutdown irradiations need to be pulled out of the core every time the reactor is operated.

This procedure will allowus to construct a gamma irradiator at the west end of the

• reactor pool.-The gamma source will be activated in a source holder.element in the core and kept in the core until needed.,It will then be moved to a fuel storage rack on the west

. end of the pool to provide the gamma flux for the samples. The gamma source will be moved with the fuel handling tool per SOP40. -The activation material will be iridium or

cobalt. The activity,will be less than 100 curies. . ',

Title:

Replacing a Control Rod with a Stainless Steel Clad Control Rod Date: January 13, 2005 Summary of Proposed Change:

During our biennial inspection of the control rods it appears that the wear on the absorber end of the Regulating Rod has become excessive. There were always two wear spots on the rod, but now they seem to be much worse. Measurements indicated that approximately 0.7 mm of the aluminum cladding has worn off at the worst location. The Triga Mechanical Maintenance Manual states that a control rod should be replaced if the pitting or cracks are 0.5 mm deep. In response to this we plan to replace the absorber end of the Reg Rod.

Fortunately, we have three spare control rods from the Westinghouse Triga Reactor at Hanford. The new control rods appear to be in excellent condition. Measurements indicate that the rods are the exact same diameter (31.75 mm) as our control rods, and are attached in exactly the same way. The two major differences are that the new control rods are clad with stainless steel instead of aluminum, and the absorber section is 35 mm shorter.

The stainless steel cladding will be an advantage in that the wear issue will probably not reappear. The control rod never comes in contact with any fuel element, so the stainless steel will not damage any aluminum clad fuel elements. The control rod is inside its own aluminum guide tube in the core. Wear of the aluminum guide tube should not be an issue. . ,.;.

The stainless steel cladding does raise health physics issues, since the cobalt in the stainless steel will stay radioactiye much.longer than the aluminum cladding with which we are familiar. Co-60.has a half-life of,5.27 years; Al-28 has a half-life of .2.25 minutes. Our procedure~fomrcontrolrod'inspection (SOP 41) already takes this into account by requiring completion of a Radiation. Work Permit (SOP 28) when inspecting stainless steel control rods.-We will exercise much greater caution when we remove the Reg Rod for inspection in two years., .. .X The shorter rod length raises two issues. The new control rod may be worth less than the existing one. If so, our core excess may increase. Our core excess is currently approximately $2.40, and is limited by Technical Specifications to $3.00.. Since the total worth of the Reg Rod is only $1.55, it seems unlikely that a 35-mm difference in length (out of a total of 545 mm) will have that large of an effect. 35-mm divided by 545 mm is 6.5%. 6.5% of $1.55 is less than $0.10. We will not reach our limit on core excess unless we lose an additional $0.60, so we should riot be anywhere near the limit. We will verify this after the control rod is replaced. The Westinghouse Triga Mechanical Maintenance Manual says their Reg Rod should be worth $1.40, which is within an acceptable range for us.

The second issue raised by the shorter control rod is the possibility that when the rod is fully withdrawn, it may come out of its guide tube in the core structure. If so, it will not easily go back in, and may become stuck out. This, of course, is unacceptable. The control rods are 545 mm long and have a vertical travel of approximately 380 mm.

When fully inserted, they are completely inside the guide tube and their tops are not visible. When the rod is fully withdrawn, the top of the control rod is still not visible. It appears that even with the new rod being 35 mm shorter, it will not come out of the guide tube. Additionally, although the absorber section is 35 mm shorter, the new rods have a spacer, so when installed the total length will only be 15 mm shorter. We will verify that the Reg Rod does not come out of the guide tube when the rod is fully Reed Research Reactor Annual Report 2C04-2005 Pagse 22 of 40

withdrawn: We Wvill test for this before all of the fuel elements are returned to the core

-(we always remove three fuel elements before we physically remove a control rod to ensure the reactor remains subcritical). We may need to return one or two fuel elements before we do this test,'in 6rderto'clear the source interlock that prevents control rod withdrawal if the shutdown neutron flux is too low. With'three elements out of the core, this interlock is activated. ,,  ;

We will do a complete calibration, scram check, and other checks of the Reg Rod when it is replaced. '** -

Title:

Moving the Reg Rod Motor Mount Date: January 17, 2005 - ' "-'

Summary of Proposed Chanie- .. - .

While investigating the cause of the wear on the regulating rod, we discovered that its motor mount was out of alignment with its core location. It is 1.25 inches south of where it should be. This is about half a ring, so the motor is not directly over any core location. It has been this way since original construction in 1968. We want to fix the alignment problem'.

Fixing the alignment will involve machining the opening for the reg rod by another 1.25 inches, producing an oblong hole. The current hole is 2.5 inches in diameter, so we cannot just drill a new hole. We will also need four new threaded holes for securing the motor in the new location.  ;;

The only apparent safety issue is ensuring that no metal shavings fall into the water during the machining. This will be accomplished by placing plastic sheeting under and around the bridge during the work. It is not possible to simply remove that section of the bridge for machining, because it also supports the other two control rods. To remove that section of the bridge, wve would have to either completely unload the core, or somehow leave the other two control rods in the core while their motors are removed; neither is simple.,

We will verify proper operation of the rod before commencing operation.

We intend to have Reed College physical plant, or a contractor, perform the work.

Linear Scram Verification Date: March 30, 2004 Summary of Proposed Change:

The Current Adjust on the Linear Power channel is not working properly. This is the method used to check the Linear Power scram. Instead of allowing the operator to adjust the test signal to the Linear Power channel with the potentiometer to test the scram setpoint, it goes to full scale and scrams the reactor. Thus it cannot be used to verify that the scram is below 110% of full power as required by Tech Spec F.5 and Table I. We are required to check this on the startup checklist per Tech Spec F.7. Tech Spec A.2 allows going to 287.5 kW to test the scram, but we don't want to use that technique.

This change will check the Linear Power scram with two other techniques during the startup checklist until the channel is repaired. The Linear Power scram will be tested Reed Research Reactor Annual Report 2004-2005 Page 23 of 40

-1lf with the CAL HI position, which is already authorized by SOP 1, Startup Checklist. The Linear Power scram will also be tested by selecting the lowest range on the Linear Power channel, (2.5 mW) and withdrawing control rods to allow subcritical multiplication to increase the power until 110% of the 2.5 mW range is reached. This will cause a scram. At that power the reactor is still subcritical.

Note that the Percent Power scram still works as normal at less than 110% of its scale.

[NOTE: this has been changed back]

Title:

Reactor On Light Date: April II, 2005 Summary of Proposed Change:

This change will add a light to indicate when the reactor console key is in the "On" position. Contacts on the console key switch will be used to enable a light in the control room (and possibly more lights) that indicate when the key is in the "On" position.

This will increase operator awareness-when the reactor is not shutdown and that an operator must be behind the console.

Specific care will be taken to ensure that the modification does not in anyway defeat or reset any scrams.

l RADIATION PROTECTION; Personnel Dosimetry.

During the period July 1,'2004 to June 30, 2005 personnel dosimeters were issued to 56 Reed students and staff, and to one contractor. Since dosimeters are changed on a calendar quarter schedule, this period is the closest to the reporting period. Individuals were issued beta-gamma sensitive ring badges and whole-body badges. The Director and Associate Director were issued beta-gamma-neutron sensitive dosimetry.

During the year the largest annual whole body dose was 13 mrem deep dose equivalent. The largest annual extremity dose was 240 mrem shallow dose equivalent. Both of these were staff members (not students). No one exceeded one percent of the federal limits.

Fixed Area Dosimetry Radiation levels are continually monitored to provide an indication of the average radiation levels in the reactor bay and dose outside the facility. All dosimeters monitor beta and gamma radiation. Two locations also measure neutron dose.

The deep dose equivalent radiation measured by fixed dosimeters during the period July 1, 2004 to June'30, 2005 are shown in Table E.iSince'dosime'iers are changed on a calendar quarter schedule, this period is the closest to the reporting period.

These come from activation of pool water and air in the pool water and in the irradiation facilities. For calendar year 2004, the average gaseous activity at the site boundary was 6.36 x 10.11 Ci/ml, which would deliver a dose to a member of the public of approximately 0.32 mrem, well below regulatory guidelines and constraints.

Figure 6 shows the gaseous releases for each year.
