SOVERVIEW This report covers the period from September 1, 2006 to August 31, 2007, and is intended to fulfill the reporting requirements of the U.S. Nuclear Regulatory Commission, the U.S.

Department of Energy, and the Oregon Department of Energy including:

• U. S. NRC, License No. R-112, Docket 50-288

• Oregon Office of Energy Rule No. 345-030-010

• U. S. DOE Reactor Sharing Grant No. DE-FG07-02ID14387

• U. S. DOE Reactor Instrumentation Grant No. DE-FG07-041D 14573 We specifically wish to thank other funding sources including:

Portland General Electric Concordia University Reed College operates a TRIGAO Mark I reactor with zirconium hydride/uranium fuel elements 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 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 thegpyrincpfe ,qn.rlernergy-ad radiation safety.

There were 2272 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 9 colleges and universities in addition to 15 pre-college groups. The reactor was operated 297 times on 119 days. The thermal energy produced was 38 megawatt-hours.

The reactor staff consists of a Director, an Associate Director, a Health Physicist, and Reed College undergraduate students who are licensed by the Nuclear Regulatory Commission as reactor operators or senior reactor operators. As this report is being written the licensed operating staff consists of 19 women and 23 men. During the reporting period, all 12 reactor operator candidates passed their NRC exams and all 9 senior reactor operator candidates passed their NRC exams.

There were no radiation exposures to individuals in excess of one percent of the limit during the year. There were no releases of liquid radioactive material from the facility and airborne releases were well within regulatory limits. There was one shipment of radioactive waste.

The Nuclear Regulatory Commission conducted their annual inspection during January 2007. There were no violations or concerns. There were no follow up items.

This non-credit course serves as an 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 reactor 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.

v Nuclear Science Consortium In order to better use the resources of the Reed Research Reactor, several area colleges and universities established the Nuclear' Sciece Conortiumpof thej*ilI ette ,alleyni 1970. Funding for the Consortium has been derived from Reactor Use Sharing Grants of the U.S. Department of Energy. This made the facility available without charge to classroom groups and unfunded research projects for consortium members.

The following institutions have participated in facility tours, experiments, and research projects in the reporting period. ,

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

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

Title:

Adding Antimony-Beryllium Source Date: November 1, 2006 Summary of Proposed Change:

This experiment will add an antimony-beryllium (SbBe) neutron source to the core as a special experiment. Although Routine Experiment #1 allows irradiation of both antimony and beryllium, when they are mixed they produce neutrons so a special experiment was deemed necessary. Ultimately this will replace the americium-beryllium (AmBe) neutron source currently used.

Reed Research Reactor Annual Report 2006-2007". P

,Page 20

.* I***'

The AmBe source is 40 years old and genergates , elium g~.s during its operation.

.Internal pressure could, someday, cause it to lre-.t lgd t6 The SbBe source does not generate helium gas. The antimopy is~activated.hb .the neutrons in the reactor, and generates a high-energy ganmua when fi dtecaysthis gamma has, TeoiuiO enFrgy to cause the bryllium to emit a neutron. This is a regenerat: vneutron source. Tliia antimouy becomes radloactiye,4at power and then itsgammas eca(60day half-llfe) ater the rea toris sliutIiowi.

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 20 mrem deep dose equivalent.

The largest annual extremity dose was 110 mrem shallow dose equivalent. Both of these were staff members (not students). No one exceeded one percent of the fed, rallimits.

Fixed Area Dosimetry Radiation levels are continually monitored to provide an ihdication of the average radiation levels in the reactor bay and dose outside the facility. This year areas dosimeters were also pl~aced inthe sample counting room and the control room. 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, 2006 to June 30, 2007 are shown in table 4. Since dosimeters are changed on a calendar quarter. schedule;,this-period is the closest .to'theffe reporting ipexod... .

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 2818 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 6 colleges and universities in addition to 12 Reed Research Reactor Annual Report 2005-2006 Page I of 28

pre-college groups. The reactor was operated 340 times on 120 daysý.The-ther.*aVrxergy produced was 42 megawatt-hours.

The reactor staff consists of a Director, an Associate Director, a contract Health Physicist, and Reed College ufidergraduite"students who are licensed by the Nuclear Regulatory Commission as. reacto? operators or senior reactor operators. As this report is being writenthelicense'doop ti n Dgn written thehg staff consists 6f,21 women and 29 men. During the reporting period, all1 6"reactior operator. candidates passed their -NRC.exams. and all 11 senior reactor operator candidates passed their NRC exams.

There were no,radiation.exposures to individuals in excess of one percent of the limit during the yea.r There Were no' eleiae:of liquid radioactive material from'the facility and airborne releases were well within regulatory limits. There was one shipment of radioactive waste.

Reactor Review Committee The Reed Research Reactor has two oversight committees: the Radiation Safety Committee and the Reactor Operations Committee. Together they comprise the Reactor Review Committee. The Radiation Safety C.ommittee is concerned with emergency preparedness, health physics, radiAtion safety, physical security, environmental impact, and the interface between.the Reed Research Reactor, Reed College, and the surrounding community. The Reactor Operations Committee deals with the day-to-day operations of the reactor, reactor maintenau.e, reactor, safety, operator training, and operator requalification. The membership. of the committees during the reporting period is shown below: .

IF A C I L IT IES Reactor Facility%' . .

In addition to the reactor, the Reed College has a radiochemistry lab. The equipment available at the reactor facility includes high purity germanium gamma spectfometers,

-alpha spectromieters, -a whole body counter, gas flow proportional counters, i6n chambers, beta counters, Geiger Muller tubes, neutron detectors, alpha~detectors, and.:thermo luminescent dosimeter readers. These instruments are used for experiments and training in hucleari scieiice atdriadiation detection. Two hafid and stio rmonifors "ar&ih the control room. A liquid scintillation detector serces the campus radioisotope' committee."The reactor facility has several systems for performing irradiations, descfib'ed b'elow.

Rotating Specimen Rack Facility tfhirobtating'speimen'rack ("lazy susan")isioated ift a wiellaon top of the 'graphite reflector'surrounding the core: The rack consists ofa circular array of 40 tubular receptacles, each of which can accommodate two irradiation tubes. Vials holding up to 17 nil (four drams) are used in this system. Samples are loaded in the specinmen 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 u..se.t..rtating rack when long irradiation times (generally greater than five minutes) are required. The approximate thermal neuton flux in aq-rotatingrack.position;at full poWer is

'. 7 k I0V;zi/cni'sý with'a,'cadmIfun ratio zof 6-.. The specimen racký dan be u sed for gamma irraditifons (aporox iffately`,8.,Rad/min) when the reactor' is shutdown.r 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 12 nlcm2 s when the reactor is at full power.

UMS ER'S Reactor Visitors A total of 28,A8nridividual-s vi-sitdd 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 643 who 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 schoois as discussed below. A graph of the history of visitor attendance is shown in Figure 1, a*ad a list for the current year is included as Appendix A.

This non-credit course serves as an introduction to nuclear reactor theory, health physics, and reactor operati6n. S.6,h..oeffthe, students continue with in-depth reactor operator training and subsequently.apply for a reactor 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, 16 out of 16 reactor operator candidatespassed their NRC exams and 11 out of 11 senior reactor operator candidates passed their NRC exams. This year, for the first time, we put a limit on the number of reactor operator candidates.

Nuclear Science Consortium In order to better use the resources of the Reed Research Reactor, several area colleges and universities established the Nuclear Science Consortium of the Willamette Valley in 1970. Funding for the,,Consortium has been derived from Reactor Use: Sharing Grants of the U.S. Department of Energy. This made the facility available without charge to classroom groups and unfunded research projects for consortium members.

The following institutions have participated in facility tours, experiments, and research projects iii the repoftihig period. .K COL.LEGE TOURS/USERS .~

Many reactor tourshinc iudl-hanrds-on u;e - of facility eqdipment't6 conduct experiments in radiation science, health physics, and nuclear physics. A typical lab involves determining the background of a Geiger Muller-scalar system and then determining thehalf-life of a sample of radioactive material. College classes are generally more closely tailored to the individual- interests and needs -of,the Consortium faculty membef. 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. .. .,

Summary of Proposed Change:

The proposed procedure will clean the lazy susan (LS) with the stolvent minera1! spirits (paint thinner).

'J*hree gallons ofi'ihe Sl'Vent will be poured into the lazy -susan. The LS Will be rotating overnight to disso!lIve the oil. Then the contaminated solvent will be pumped into-a

""shielded odntliner. The waste will be haridled'a d&scribed beloo`. The *p0de e is "attached. '- . .. .

The LS is an air filled rack assembly that is isolated from the pool water, so there is no possible interactiontbetWeen the: solvent and the reactor. water. Mineral spirits is, compatible with. metals;,, plastics, and-the pool: water if any were to getinto the pool. The

.only significafitactivation product is' sodium (15 hour1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br /> half-life), although the LS oil will have long-lived cobalt and selenium isotopes. This method was used successfully at the Kansas State University Reactor in 2003.

The pump and tubing will be on absorbent paper and will be checked frequently for leaks.

Radiation -mohitors willi check.for air contamination and for high radiationifields. Lab coats, glove's ,shoe"coyers, andl goggles will; be worn when transferring the:solvent.

Personial ddsimotry is always worn iný the-reactor room. The container -v'ill be shielded and will not belpositior*d tover the reActof pool. When Kansas State performed the procedure, the highest measured dose rate was 10 mR/hour.

The used s6lvent will bqfiltered to.rermove .the radioactive particles. The solvent will then be stored for u_ jncleanilzj the LS in thefuture. _

This procedure will be added to SOP-83 with lessons learned when completed.
