Walnut Creek, California 94596 5368 Re: Licensing examination conducted by Mr. Tom Meadmys at this site on 16 20 May 1988. Docket 50 288 License R.il2, .
Dear Mr. Pate:
I have the following requests, referenecd by question number, in regard to the Reactor Operator's Exam:
A.08 Accept answer "c" as equally correct. Delayed -neutrons are born at energies below the 1-2 MeV energy range, while prompt neutrons are born fast." ,
Justification: Answer "c" is correct and is an 'even - more precise description than is the key. answer "b." Our Training Manua!, on page 5-12, lists the delayed neutron energies as 250, 560, 405, and 450 kev, while the more recent reference, Glasstose and Sesonske 3rd ed. (see '
Ist anachment) lists the energies as 0.25, 0.46, 0.41, 0.45, and 0.41 MeV.
Figure 2.26 on page 112.of the same reference, shows; how the delayed neutrons arise from de excitation of the precursor daughter nuclei, _ and so, such neutrons must be monoenergetic. On the other hand, answ,r "b" correctly describes both prompt and delayed neutrons. as " fast" '
which 'is in accord with most chartacterizations of the fast group _ as beginning at 10 kev. In particular, it is _the definition used in the' RRF Training Manual (see attachment 2) and in Glasstone and Sesonske _3rd ed. (see attachment 3). "
D 03 D!sregard part a.
~
. Justification: _ Our trainees rre freshmen or sophomores majoring in '
physics, chemistry, or mathematics. Such.. persons have' no ' >
understanding of the descriptors " synchronous" _ or i "nonsynchronous" in connection with - motors. Rather, the information is of benefit only to 3 management in replacing components to the ~ original- specticiations.
. E.02 Accept as an equally correct answer "d. Pt.rticulate Stack Monitor."
Justification. ' The information for the key answer, i.e. the CAM, was ,
obained from an appendix- to our - Emergency Implementation -

, emergency situations. In actuality, the setpoints change depending on detector efficiencies and sampling flow rates, both of which are subject -
to change at each calibration and at any . Intervening maintenance. The current setpoint for the CAM is 4000 cpm, and for the PSM is 3000 cpm. The question implies current information, and makes no mention of the EIP document as a source. Thus, since neither the CAM nor the PSM is currently clow to. 2000. cpm, either abould be acceptable.

It should be noted that the approximate energies of the delayed neutrons, given in the last column of the table, are lower than for the peat majority of prompt neutrons. 2.191. Most of the neutron rich fusion products undergo beta decay ($1.49);in . a few cases, however, the daughter is produced in an excited . t with sufficient en-ergy to make possible the ernission of a neutron. It is in this manner that the de-layed neutrons arise, the characteristic halflife being determined by that of the tilar equa. parent (or precursor) of the actual neutron emitter. The (approximately) 55-s and
.nd pluto- 23.s poups have been dermitely associated with bromine 47 and lodme 137 as pre-atted as a cursors, respectively, and krypton 47 and xenon 137 as the conesponding emitters.

~ 10 MeV. a magic number ty unity, viz.,51 and 83, respectively. This means that the last neu- l af reactor ' con has a low binding energy and is, consequently, easily emitted.
2.192. The mechanism proposed to account for the 55 s poup of delayed neu-trons is shown in Fig. 2.26. About 70 percent of the beta decays of bromine 47 (halflife 55 s) lead to the formation of an excited state (or states) of krypton 47, with excitation energy somewhat pester than the binding energy (B.E.) of the last cas have neutron,i.e.,5.4 MeV,in that nucleus. This excited state can then immediately emit Tsnite ex. , a neutron, leading to the fermation of stable krypton 46; the energy of the neutron 4th each l is indicated by E, in the figure. Although neutron emission is shown from only one are cJose excited state of krypton-87, there are probably several closely spaced statesinvolved; umber of hence, there is a small range of neutron energies l'he observed rate of delayed neu-neutrons tron emission is determined by the rate of formation of krypton 47 and this depends uranium. on the rate of decay of bromine 47.

For many elements, especiaDy those of mass number exceeding 100, en i examination of the viriation of the absorption crou sections with neutron energy re. , veals the existence of three regions.* There is, first, a low. energy region, where the ' i l cross section decreases steadily with increasing neutron energy. De absorption cross l l section o, then varies (approximately) inversely as the square root of the neutron I l energy, and since the energy is kinetic in nature, o, is inversely proportional to the neutron speed. This is called the 1/u region, and the neutions are said to obey the l 1/v law. I 2.138. FoUowing the 1/u region for slow neutrons, the elements under considera. ! tion exhibit a resonance regmn, usually for neutrons of roughly 0.1 to 1000 eV en. ! ergy. This region is cbracterized by the occurrence of peaks where the absorption cross secuon rues fairly starply to high values for certain neutron energies and then I faUs again. Some elements,e.g., cadmium and rhodium,have only one high resonance I peak, while others, such as indium, silver, gold, and uranium 238, have two or more
, ! peaks. The crou sections at the resonance peaks are sometimes very large,e.g..more l j than 2 X 10' b for cadmium.ll3 at a neutron energy of 0.17 eV and 3.4 X 10' b for I l xenon.135 at 0.7 eV energy. ne total cross section of umaium.238 and the total and l

" Fast neutrons" are those with energies between 10 kev and one MeV. -From a radiation protection standpoint, these The velocity of fast are the most hazardous neutrons.
neutrons can be calculated in the same manner as was done for thermal neutrens.
" Relativistic neutrons" are those with energies greater than :',0 MeV. This. energy is generally greater than the binding energy of most nucleons, and they are thus par-ticularly effective at fragmenting nuclei with which they collide. The term relativistic comes from Einsteinian physics, which notes that, as the velocity of an object approaches the velocity of light, it gets heavier and heavier until, at the velocity of 31ght, its mass becomes infinite.
The four energy groups are most useful in character-izing -the types of nuclear interactions that predominate in each energy region. Thermal (also known as slow) neutrons are most commonly involved in nucicar reactions that result in their capture by a nucleus, usually with the emission of a gamma ray or most fission reactions. l The absorption or capture of intermediate. energy neu-trons is marked by a series of peaks or points of high affinity for neutrons'of_a particular energy. These are known as resonance peaks, and hence intermediate neutrons are sometimes known as resonance neutrons and are terget specific.

- Denotes those individuals attending the exit interview on June 3,1988.
- 2. Reactor Operations
- a. Organization The licensee's organizational structure was examined and found to be consistent with Technical Specifications, Section I.1, and the licensee's Administrative Procedure, dated October 1987.
A new Director assumed responsibility for the safe operation of the reactor and its associated equipment in Se . 1987. The previous acting Director was appointed as t /'s Associate Director. -Both the Director and Associate t. rector are part time positions (i.e. three days per week). The Directors' working days are staggered such that one or both individuals are at the Facility throughout the normal work week of Monday through Friday. The new Dir'-: tor previously held the same position at another Research Reactor and held a Senior Reactor Operator's license. The Director had also been a Nuclear Engineering instructor at University of California at Berkeley for twenty-seven years prior to dssuming his new responsibilities at the RRF. The intpector notnd that there was a significant improvement in the RRF staffs' oerformance since the previous inspections conducted from 1985 through 1987. No violations ur deviations were identified.
- b. Procedures An examination of the licenree's Standard Operating Procefutus (SDPs) was conducted for the purpose of_ verifying compliance with Technical Specifications, Section 1.5. ,
Actions were taken by the licensee's staff af ter the previous NRC inspection to review and revise the RRFs Administrative Procedures and the RRF SOPS. Resources to accomp'ish this were made available during the summer of 1987, at which time all of the SOPS were revised as described in paragraph 2(e) of Inspection Report 50-288/87-01.
2 The inspector disclosed that several of the revised procedures have not been implemented even though they had been reviewed and approved by the Reactor Operations Committee. The RRF Director informed the inspector that he wanted to personbily review the revised p-scedures to ensure they were adequate prior to their being implem' ente.. The inspector emphasized the importance for imolementing the revised procedures in a timely manner. The licensee's performance in this area appeared to be improving and seemed capsble of meeting its safetv 'n ' ctives. No violations or deviations were identified.
- c. Loos and Recoro The inspector examined the following facility logs and operational records for the period iof July 1,1987, through June 1,1988:
- Console log
- Environmental monitoring log
- Startup check list Shutdown check lists
- Reactor operator records
- Weekly, Monthly, Bi-monthly, Semi-annual and Annual check lists that are used for verifying that the Technical Specifications are performed at their required frequency,
- Health Physics Survey Records
- Naintenance Log
- Operator Requalification Program Training Records The review did not disclose any missed Technical Specification survefilances or abnormal findings.
The licensee's performance in this area seemed to bt improving and seemed capable of meeting its safety objectives. No violations or - deviations were identified.
- d. Site Tour 3
A tour of the RRF facility was conducted. During the tour the inspector noted that the licensee's posting and labeling practices were consistent with 10 CFR Part 19.11 and 10 CFR 20.203. Independent measurements were performed with a Model R0-2, ion chamber, survey meter, serial number 1694, that is due for calibration on October 10, 1988. The independent measurements confirmed that the licensee's posting practices were consistent with 10 CFR 20.203. The inspector witnessed a Subcritical Multiplication Experiment that was conducted on June 2, 1988. A group of students from a local college participated in the experiment. The inspector noted that reactor operations were conducted in accordance with the RRFIs SOPS.
3 The inspector noted that the facility was exceptionally clean and that portable radiation survey instruments were in current calibration. . The licensee seemed to be maintaining their previous lev'el of performance in this area. No violations or deviations were identified.
- e. Requalification Training The inspector reviewed reactor operating logs and training files for each reactor operator to verify that the licensee was maintaining the requalification program for all reactor operators in accordance with the licensee's NRC approved program of 1980. The program was
- designed to meet the requirements prescribed in 10 CFR 50.54(1) and 10 CFR 55, Appendix A.\ Discussions of recent changes made to 10 CFR Part 55 and of Information Notice (IN) 87-22, " Operator Licensing Requalification Examination at Honpower Reactors," were held with the licensee's staff.
The review disclosed that the program was being implemented in accordance with the regulatory requirements and IN 87-22. The licensee seemed to be maintaining their previous level of performance in this area and their program appeared adequate to accomplish its safety objectives. No violations or deviations were identified,
- f. Surveillances The inspector verified that surveillances prescribed in the Technical Specifications were performed at the required frequencies.
Surveillance records for the period of March 1987 through June 1988 were examined. Data related to the following surveillances were reviewed:
- Pool water analys 's for conductivity
- Pool water tempert+ure monitoring
- Fuel element inspecti,rs
- Control element inspections
- Control element drop tir u
- Operational checks of t eactor instrumentation channels and safety circuits listed in Table I and II of the TS
- Ventilation system functional checks
- Calibration and functional checks of radiation monitoring equipment identified in >Jction G of the TS
- Other surveillances established by the licensee's SOPS .,
Improvements in the documentation of maintenance activities and surveillance records were observed. The inspector was informed tt.at the new method for performing rod drop time measurements, using a computer system, was expected to be ready by the end of the summer school semester. The new method is expected to provide the licensee The with a more precise method for measuring the drop times.

The licensee's performance in this area' appeared to be i.mproving and seemed fully capable of meeting its safety objectives, ho. i violations or deviations were identified.
- g. Experiments i
The inspection disclosed that two new experiments had been approved by the Reactor Operations Committee in accordance with Technical Specification requirements. No violations or deviations were identified.
. i
- h. Review and Audits i The licensee's review and audi* functions assigned to the Radiation Safety Committee (RSC) and Reactor Operations Committee (ROC) were examined and were found to be consistent with th? regulatory requirements prescribed in Technical Specifications: Section 1. RSC and ROC meeting minutes and audit reports for 1987 and 1988 were reviewed as part of the inspection. The inspector noted that both committee's had met at a greater frequency than was required by their respective charters and the technical specifications.
Tne inspectors concluded that the licensee's review and audit program met or-exceeded the Technical Specifications requirements. No violations or deviations were identified.
- 1. Changes The licensee's staff stated and a review of records / logs discussed in paragraph 2.c indicated that there had.been no changes made'to the facility that would requirt a safety. evaluation be made pursuant to 10 CFR Part 50.59. The_inspecter verified that procedure changes were properly evaluated for their safety considerations pursuant- to 10 CFR Part 50.59.
No-violations or deviations were identified.
- k. Hea'th Physics
- 1) Liquid and Solid Waste No liquid or solid waste was generated or disposed of since,the previous inspection period.
No violations or deviations were identified. 2). Personnel Monitoring a o
5 The licensee's program for assuring compliance with 10 CFR Part ' 20.202 was examined and was found to be consistent with 10 CFR Part 20.101 and 10 CFF Part 20.104. No violations or deviations were identified. 3). Radioactive Material Shipments and Recef t A review of radioactive material shipping and receiving records disclosed that activities related to this subject area were in compliance with 10 CFR Part 20.205, 10 CFR Part 71, and Department of Transportation regulations prescribed in 49 CFR Parts 173-178.
- No violations or deviations were identified.
4). General Employee Training The licensee's General Employee (GET) training program, for assuring compliance with 10 CFR Part 19.12, " Instructions to Workers," war examined. GET training lesson plans, attendance records, and hand-out meterial were reviewed. The inspector concluded that the licensee's GET program met or exceeded 10 CFR 19.12 requirements. No violations or deviations were identified. 5). Surveys The inspector verified that direct radiation surveys, contamination surveys, and special surveys are performed on a routine basis. The review disclosed that no abnormal radiation measurements were identified and that contamination surveys continue to show no activity above bacxground. The inspector noted that the licensee does not routinely sample the reactor pool water for radioactivity levels, does not have any survey instruments for performing alpha or neutron-measurements, and does not have a portable air sampler. The above observations were discussed with the licensees staff. Both the Director and Assistant Director stated that arrategements have been made with off-site agencies to provide such monitoring instrumentation during emergencies. The Directors added that the ROC had recommended that a schedule te developed for (ampling the reactor pool water on a routine , basis, such as monthly or quar ^ 2rly. The Assistant Director stated that action would be taken to obtain and post some control neutron badges in the RRF to determine what the neutron dose rate may be from reactor optrations. The Directors also stated that the RRF's stack and reactor bay Constant Air Monitors (CAMS), which operate continuously, would provide an early alarm function in the event of a fuel leak.
6 The above observations were also discussed at the exit interview. The inspector was informed that the observations would be brought to the attention of the RRF health physicist for resolution. , In the areas inspected, the licensee's programs exhibited weaknesses as detailed above; however, the overall program appeared adequate to accomplish its safety objectives. No ! violations or deviations were identified. 6). Environmental Monitoring Ti,e licensee's environmental monitoring program prescribed in 50P-20, " Environments 1 Sampling," was examined. The program
- had not changed from what is described in Inspection Report 50-288/87-01. Results of the licensee's off site monitoring (e.g., water sampling, soil sampling, and direct Thermoluminescent Dosimeters (TLD) measurements) performed since the previous period were reviewed.
The inspector concurred with the licensee's observations that there had oeen no detectable or meaningful increases of radioactivity in the environs as a result of RRF operations. In the area inspected, the prograr appeared capable of accomp',ishing its safety objectives. No violations or deviations were identified. 7.) Effluent Monitoring The principal airborne radionuclide released from the facility was Argon-41. Inspection Report 50-288/87-01 identified that the licensee monitors airborne releases with a constant air sampler (CAM) that monitors Ar-41 and particulate releases from the reactor pool area and a stack CAM monitor that monitors particulate releases. On a high CAM alarm, the P.RF ventilation system is I diverted from an unfiltered exhaust system into a filtered exhaust system containing a HEPA filter. Calibration of the pool and stack monitors is per.sre V annually. The alarm set points are based on the 6...c permissible concentrations for Ar-41 that is prescribed in 10 CFR 20, Appendix B Table II. , Column 1. The calibratior.s are performed with known quantities of Ar-41 that are prepared in the reactor. Records of releases are maintained on stri; charts. A review of the strip charts for 1987 disclosed thst the readin> were barely above background level. The licensee's staff were in the process of calibrating both CAMS during the inspection. The staff informed the inspector tnat they had discovered that the CAM's air flow volume measurements readings were a factor of four ice due to an
l' 7 undersized orifice in the CAM's magnehelic gauge. The licensee made this determination through conversations held with vendors that manufactured the CAM. It appeared that the problem hat existed since the CAM was first put into operation, some 15 . years ago. The stack CAM air flow measurements wene determined to be satisfactory. The licensee performed a preliminary review of the strip charts collected during previous peak reactor operations and determined that all prior releases from the facility were within 10 CFR 20, Appendix B. Table II, Column 1 limits. The staff added that they were still evaluating the previous data. The RRF Director and Assistant Director stated that the CAM's air flow volume calibration was condacted because of a question raised by the inspectcr during a previous inspection period. The staff added that calibration procedcres for the CAM's will be revised to include the recommendations of Regulatory Guide (R.G.) 8.25, " Calibration and Error Limits of Air Sampling Instruments for Tote: Volume of Air Sampled." The inspector noted that the licensee's staff still had not devr?oped a method for quantifying the activity measured by the CAM'; in microcuries per milliliters and total curies from the i chart readings. The above observations were brought to the licensee's attention during the exit meeting. The inspector emphasized the importance of assuring calibration of instrumentation is performed in a manner that is consistent with the Industry Standards such as what may be prescribed in R.G.'s and American National Standard Instructions (ANSI). In the area examined, the licensee's performance appeared to be improving and seemed capable of meeting its safety objectives. No violations or deviations were identified.
- 3. Information Notices The inspector verified that the licensee was receiving and evaluating Information Notices in a timely manner. ,
Licensee evaluations for Information Nctices received between January 1985 through June 1, 1988, were reviewed. The licensee's evaluations were well documented. In the area inspected, the licensee's performance appeared capable of superior performance in accomplishment of their safety objectives. No violations or deviations were identified.
- 4. Emergency Plan Implementation
' The licensee's capabilities for responding to emergrmcies as specified in the approved Emergency Plan dated February 1986, ant for demonstrating 1
8
- compliance with 10 CFR part 50.54(q) and 10 CFR Part 50. Appendix E, were exsmined. ~
The examination included a review of applicable training records, emergency plan implementing procedures, emergency response equipment, drill scenarios, drill crii.iques and discussions with the licensee's staff. Also examined were the memoranda of understanding maintained with offsite agencies such as the Fire Department, Police Department Hospital and State of Oregon emergency response organization. The inspector noted that the licensee had conducted two emergency exercises since the previous inspection and were in the process of participating in an exercise involving several off-site agencies. This c exercise is tentatively scheduled for Jane 24, 1988. The exercise will be used to verify the licensee's communications capabilities with of f-site agencies as is re:;dired by the Emergency Plan. The inspector noted that none of the exercises performed to date had involved a medical emergency involving a simulated contaminated individual. The Emergency Plan requirer that a scenario involving a medical emergency be performed periodically. Thic observation was brought to the licensee's attention. The licensee informed the inspector that they would plan to conduct an exercise involving a medical emergency with'n the next fiscal school year. The inspector noted that the required Emergency Plan annual reviews had been conducted by the RSC and ROC pursuant to paragraph 10.4 of the plan. A examination disclosed that the licensee's review had been thorough. The RSC and ROC were evaluating the comments raised in the review. The licensee suspects that it may be necessary to make some changes to the plan in order to clarify responsibilities and ambiguous statements contained in the current plan. The inspector informed the licensee that changes should be processed in accordance with 10 CFR 50.54(q) Tequirements, Ir. Ne area inspected, the licensee's program appeared adequate to accomplish its safety objectives. No violations or deviations were identified.
- 5. Followup Items (Closed) Followup Items 85-01-02 and 85-01-05 related to the adequacy of logs and records and Standard Operating Procedures are discussed in paragraph 2. The inspector concluded that the licensee's actions in these areas were satisfactory. This matter is closed.

aEACTOR F ACILITY ~o 0 A9: gl 6 January 1989 Ross A. Scarano, Director Division of Radiation Safety and Safeguards U. S. Nuclear Regulatory Commission 1450 Maria Lane, Suite 210 Walnut Creek, California 94596-5368 Re: Docket 50-288, R 112 REPORT ON ERRANT-CONTROleROD INCIDENT OF 12/16/88 INITIAL PROBLEM On the afternoon of December 16, 1988, the reactor was being operated as part of the requalification requirements of an RO and for an intended irradiation. The reactor checklist was completed at about 13:35 with no indication of any problems. The first operation, measuring of the core excess at 5 watts, was completed at 13:54 under the observation of the SRO. An inadvertant period scram occurred during this start-up but was attributed to the relative inexperience of the operator. At that point, the SRO went into the adjacent radiochemistry lab to finish preparing a sample foi irradiation leaving the RO of record and another licensed RO in the control room to practice reactivity tuanipula tions. The RO had raised the reactor power to 150 W and was manipulating rod up and down buttons to stabilize the reacter at that level. At approximately 14:17, the operator experienced an unintended power increase, taking the reactor from 150 watts to about 250 watts. This increase was halted and reversed, without the occurrence of a reactor scram, by the operator inserting rods into the core using all three rod-down buttons. Then, as the operator began to stabilize the reactor power again, the RO nnticed that the Safety Rod was at it's upper extreme despite the fact that the RO believed that all rods had been driven down to correct for the original power increase. At this point, the SRO was notified and the reactor was manually scrammed, pending a review of the operation. When initial evaluation suggested a possible equipment problem, the Director was notified. Foltowing a review involving the Director (SRO), Associate Director (SRO of record), the RO of reconi, and the additional RO who had been present at the original incident, the Director concluded that the unexplained pr.wer rise was probably operator instigated, but to allow for the possibility of equipment malfunction, he requested the operation to be repeated exactly as originally performed under the careful observation of all present. Beginning at 15:16, the RO took the reactor to 5 watts, measured the core excess, and then proceeded to 150 watts as before. The power w .s stabilized at that level at 15:40 with no repeat cf the power rise. It was noted that this resulted in the Safety g /p(. 4 Rod position being approximately 1/2 to 2/3 of it's fully withdrawn position, 4i I o far below the level it had achieved during the earlier operation. p _- , p ,

2 In order to test the hypothesis that the problem was a sticking switch, it was decided to maintain a reactor power of 150 watts (50% on the 300 watt linear power range) but to raise and icwer rods (especially the Safety) alternately by small incremer.ts, essentially to continue the operation which had been in progress. After about 15 minutes of uneventful operation of this type, the Director left the Control Room, requesting that the Associate Ditector directly observe additional testing and that the reactor be immediately scratamed if any additional problems occurred. At 15:52, following a short activation of the Safety Rod "UP" button, die Safety rod continued to rise even though there was no finger on the button. The reactor was thereupon scrammed by the - operator. The Director was immediately notified and returned to the control room. He ordered that no further criticalities would be undertaken until the problem was resolved. From 15:54 until 16:13, the safety rod only was tested by the Associate Director with the other two rods fully inserted in the core to insure that the reactor remained subcritical. Once during this time, the rod condnued to rise after a short activation of the up switch. This rise was halted by a quick tap on the "UP" button. The mechanical portions of the switch were removed, disessembled, and inspected, as were the mechanical portions of several other rod drive switches. All were noted to be dirty; however, due to the 1steness of the day, it was decided to suspend funher testing. At this poit4t, the Director initiated a discussion on whether an immediately reportable incident had occurred. He concluded in the affirmative, and the NRC, the Provost, the Chairperson of the Reactor Review Committee, and the Oregon Department of Energy were thereupon notified. ADDITIONAL INVESTIGATIONS 12/17/88 Prior to additional testing, the Associate Director and the Reactor Supervisor comp!cted a review of all past problems with control rod drives by examination of the Mechanical Maintenance Log. Main Log entries for several of these were also examined. One previous occurrence of a similar nature was identified as having occurred on !!4/74. Mechanical Maintenance Log and Main log entries of that occurrence were located and copied . Phone discussions were held between the Associate Director, who by coincidence had been the operator of record on that date, and the person who had been the Director at the time and who was the individual who recorded the log entry on the final resolution of the prcblem on 1/8/74. In that case, the problem was traced to- mechanical binding in the upper portion of the Shim Rod "UP" switch. It was resolved by exchangir.g this portion of the switch with identical parts from the unused " Transient Rod" "UF" switch. The log describes testing of the switet successfully approximately 30 times following the exchange, and no furthe.r problems with that switch were recorded in the logs reviewed. . A discussion was aho held with the chief TRIGA scientist at General Atomic, who advised that Fimilar problems had occurred at G.A. in which mechanical binding of the plastic portion of the switch was found to have been responsible. The GA official r.dded that such problems have always been easily colved by cleaning the mechanism, sanding off the plastic "UP" label, or exchanging the mechanical portion of the switch. GA reported that no problem had ever been documented with the actual switch itself.
i 3 l h, i NOTE: GA warned us that removal and replacement of the switch itself, should I we decide that such is necessary, must be done with extreme care si 2ce the soldering is very fine, and many. of the required reactor safety systems including SCRAMS and interlocks are wired theth this switch. TESTING 12/22188 On this date, additional testing of the Safety Rod was conducted by the Aest,ciate Director (SRO) and the Reactor Supervisor (SRO). The primary goal was to ascertain, if possible, whether the problem was mechanical, in the upper portien of the switch, or electrical, in the lower portion of the switch. The Safety Rod was tested by repeatedly activatir;', the 'UP" and "DOWN" switches. Tests of the Safety Rod "UP" switch were tallied. The rod was tested throughout the range of it's travel. It was tested by both SRO's. Tests were conducted by holding the botton down for long periods of time, by quickly tapping the button, and everything in between. The botton was tested repeatedly by pushing it in the middle as well as on each of it's edges. After a total of at least 660 activations of the button, the previously demonstrated unintentional rod raising had not been observed. One unusual thing, however, was observed. At approximately Test #170 with the Safety Rod at a Position of approximately 1260 (2/3 of it's maximum withdrawal distance), the rod tailed to rise when the switch was depressed. Both SRO's observed this occurrence and verified that the source interlock was not activated at the time. This aberration also never repeated. CONCLUSION AND RESOLUTION 1/6/89 By this date, a letter was on hand from NRC Region V reiterating our obligation to notify NRC before attempting any further criticalities. On the basis of the tests reported above, and in consideration of the advice from GA, we concluded that the sticking of the switch is a rare phenomenon, whose cause is most probably in the mechanical portion of the switet Hence, we removed the UP and DOWN bcttons from all 3 rods, and the mechanical linkages which they activate. The linkages were cleaned in a pressurized-gas stream, which had the effect of removing some solid material which had deposited on their surfaces. Next, in each linkage, lubricant was sprayed between the actuating rod and the bushing through which it passes. Finally, pieces of dirt and other debris were removed from the housings into which the linkates are inserted. The switches tere then reassembled, and each UP and DOWN button was tested 20 times, with no unusual behavior observed. At this juncture, the Director informed the NRC by phone of our proposal to resume criticalities. As soon as possible, the incident will be reviewe,d with all operators, who will be alerted to watch carefully for any aberrant control-rod behavior, and to scram the reactor promptly and notify the Director if such occurred.~ The Director will also put the cleaning and lubrication of the control-rod linkages on a rehularly_ scheduled basis.

Dear Mr. Scarano:
Persuant to a request from your staff, I am _. writing to supply some additional information regarding- the incident referenced above. SAFETY IMPLICATIONS In the hypothetical event that the. operator does notl terminate q the power rise when the Safety-Rud -UP switch sticks at 150 W, the ramp reactivity insertion with . a rate . less than 50.16/s', _ would result, . P after 4.3' s, -in .a period scram at 288 W on the 300-W scale. We proved this ~ expetimentally, since the situation is . difficult te- analyse theoretically, i.e. the Point Kinetic Equations are non-linear. _ L
.It is a~ tribute to. the designers of the TRIGA: Mark I_ that in a worst-case situation analysis, where all of the permitted $3.00 of -
l- bxcess reactivity _ were- to be inserted into. the core, and all scrams
~
were to fail, the reactor power: would rise -to a steady value,:albeit above the . licensed limit, but nevertheless at which fuel integrity
.would be maintained (see Reed lSafetyf Analysis Report Fig. 7-1).

- 3. .Written Examination and Facility Review:-
16,.1989. Written examinations were administered at Reed College on May At the conclusion of the examination copies of the SR0 and R0 examinations and associated answe, keys were provided to Mr. J. M. Pollock for coordination of the licensee's examinction review. On May 18, 1989 the Chief Examiner met with the facility reviewers to discuss their comments on the written examination. The facility comments' and NRC resolutions for the SRO, and for the R0 written examinations are included as-Attachments A and B, respectively. The resolutions to the facility comments were incorporated into the SR0 ano R0 written examination answer keys prior to the grading of the j' examination.
- 4. Operating Examination:
Tre SR0 and R0 operating examinations were administered from May 16 inrough May 18, 1989. During the operating portion of the examination, three generic weaknesses in the operator training program were identified. The areas identified were: l- ! a. Training of operators in the aret of radioactive material transfer procedures and processes. ' The operators need to be familiar with procedures for the transfer of r;dioactive material, specifically within the facility. No.. of the candidates were unfamiliar with the processes and the location of procedures for the transfer of radioactive materials when questioned in this area during the operating examinations. l
- b. Training of Reactor Operators in the area of reactor kinetics. 9 Safe reactor operators- are required to be knowledgeable in the areas of reactor kinetics in order to prevent or citigate the effects of potential reactor accidents. ;
Some of the candidates examined did not appear adequately trained in the area of reactor kinctics. Examples of this condition were: One of the candidates was unable to explain what " critical i operation" meant. , A candidate incorrectly identified the reactor as critical when it wa. well below the point of criticality during a i reactor start up.
- c. Training of reactor operators in the areas of radiological controls.
~
Operators are required to be aware of and conform to the proper use of radiological controls. Some of the candidates did not adequately understand proper measures to control radioactive contamination. This weakness was identified by the following examples: One of the candidates tried to leave the reactor bay area without frisking their hands or feet as required by the Reed Reactor Facility procedures. A candidate placed a bare hand in the potentially contaminated
" rabbit" terminal box. After the candidate frisked the hand and put on protective gloves the candidate touched his face and nair with his potentially contaminated gloved hands that he had used to demonstrate the operation of the " rabbit" system.
- 4. Exit Meeting:
At the conclusion of the examination on May 19, 1989 an exit meeting was held with the facility. During the exit meeting the generic training problems identified in paragraph 3 of this report were discussed with the facility representatives, who agreed to review these weaknesses.

- a. General Drs. James L Powell and Douglas Bennett have replaced Drs. Bragdon and Cronyn as the President and Vice President-Provost, Reed College, respectively. The remainder of the RRF administrative and academic staff remain as described in Inspection Report 50-288/88-02. Both the Director and Associate Director RRF are An additional SRO license is held by a professor at licensed SRO's. The principal operating staff, SRO's and RO,s, Pacific University.
are students, who have completed the necessary training as an extra curricular activity. The normally assigned Reactor Supervisor,This a student SPO. was not present on the campus during the summer. position u filled by a student SR0 in an acting capacity for the summer. At the t'ime of the inspection a three week, National Science Foundation workshop, involving irradiation of geologic samples, was being conducted on the Reed campur. The inspection established that reactor operations were consistent with the information provided in the licensee's annual report for the period September 1,1987 - August 31, 1988. The inspector observed reactor operation including startup and shutdown, power increase, sample irradiation and handling and recovery from an unanticipated event. The licensee's program and staff appear to be No violations or adequate to meet their safety objectives. deviations were identified.
- b. Organization Except as noted in the previous report section, the licensee's orgtnization, related-to reactor operations, remains as previously .
described. A total of three committees, the Reactor Review- 1 Committee (RRC), the Reactor Operations Committee (ROC) Theand theis, RRC Radiation Safety Committee (RSC) are active on campus. in fact, an incor, .ation (integration) of the ROC and RSC as The two subcommittees do not meet as a single subcommittees.
.- ~.- .-
2 committee, each conducting their meetings as indep~ dent entities. The RSC and ROC are specifically identified in the Technical specifications (TS). The licensee plans to propose an amendment to the TS, combining the ROC and RSC into one comittee with two subcommittees. The committees are reconstituted each year, The Formal membership meets the requirements specified in the TS. minutes of comittee meetings are maintained and were on file. Since June 1988 the ROC had met three times aad the RSC twice, at the time of the inspection. h was noted that the ROC reviewed all proposed procedure changes, new, changed or revised experiments, and 10 CFR 50.59 changes. Due to infrequent committee meetings and the committees diligence in reviewing procedure changes, proposed procedure changes are frequently delayed. This has occurred at a time when the licensee has been revising, updating and reformatting a significant number of procedures. It was noted that the licensee's organization and eperatkos met the requirements specified in TS Sections 1. A.dmin,Wrative Requirements 1.- 5. The licensee is supported in the area of health physics by a : consultant, two days per month. The consultant reports to the Vice President-Provost and the RRF Director. The consultant is supported j by a Reactor Assistant, a student employee, who functionr. as a haalth physics technician at the reactor facility and at on campus laboratories conducting activities licensed by the State of Oregon, in this area the licensee's program appeared adequate to meet their > safety objective ;. No violations or deviations were identified.
- c. Review and Audit The ROC and RSC establish audit schedules which are implemented by various members of the committees. The ROC conducted an audit of the bimonthly and annual checklists, 9r the period January 1987 to May 1988, in June 1988 with a follow-sp audit of weekly checklistsThe and the main log and general facility operations 90 days later.
Director RRF responded *,o the audit findings. The ro ults of an audit of the same general topics was set =duled for review at the next meeting of the ROC. The RSC had established an audit schtdule and had conducted an audit of the emergency plan. The audits appeared adequate to meat the liceasee's safety objectives. No violations or deviations were identified. - d. Corrective Actione, for Unusual Events and Occurrences Since the last inspection the licensee had reported several events. On October 18, 1988, the licensee reported a small chemical fire in the chemistry building whi:h houses the RRF, on October 17, 1988. The fire was extinguished by students promptly, however, the smoke alarms were activated and the fire department rcsponded. The RRF
'nas shut oown, secure, with no experiments in progress and e.c occupied at the time. The fire department evacuated portions of the chemistry building and used blowers to clear the smoke. .The reactor staff wLs not notified of the event promptly and therefore p ,m ,, , , ,,p , , , , , *'"W'e eg + h.- e eq ,e,e ,,9 ~%

The licensee had initiated action to revise the emergency plan to limit Notification of Urmsual Events, to those fires, to which the fire department responds and which require evacuation of the entire chemistry building. Thewhich ifcensee submitted a report of this event proposed the corrective attions noted dated Jancry 17, 1989, atjove.

' 5 The inspector bad the opportunity to observe the studert R0 and SRO ourbu sta% and completion of the Startup Checklist, including rod crop tieg measurement, interlock verifications including, instrument scram settings, source count rate interlock, single rod motion interlock and core e: cess reactivity check and reactor shutdown. Operation at 5 W, 5 kW and approach to and operation at full power (administrative 1y limited to 94%, 235 kW) was observed.
The licensee had imposed the administrative limit due to a fluctuating response of the power indicating channel and recorder. The licensee had taken a:: tion to minimize the fluctuations by repositioning the circulating water return to minimize ths apparent The licensee reported that the apparent vibration of the detector. fluctuations had been reduced to approximately +1% of full power. The licensee had not approved operation at increased power following the change in the cooling water discharge flow path. The inspector also witnessed the operation of the pneur,,atic irradiation sample transfer system (7abbit) and " lazy susan" facilities and the insertion and removal of samples from these devices. It was noted that the operators used good radiation protection practices in the recovery of samples. It was noted that the operating procedures reflected the as-built It system and that the operators were familiar with the procedurer. was noted that the operators were able to conduct their at.tivities in accordance with the procedures, withow having the procedures in hand. Current copies of the operating and emergency procedures were available in the control room. Shortly before the inspection began the licensee had received a shipment of fuel and spare parts from the University of California, Berkeley T.
- IGA facility. The shipment included four new, unirrediated fuel' elements (20% enriched), used irradiated fission chambers and several fuel storage racks. The licensee noted that this material addition to the facility inventory significantly The licensee added to the potential operating lifetime of the reactor.
stated that prior to the receipt of the new fuel the only fuel on hand, in addition to the core, was one dummy element and one ele'nent which had been dropped while being moved, several years earlier. The lower not usable. core plate locating pin had been damaged and th The University of California, Berkeley had requested authorization for the use of a Model No. TRIGA-1, Type USA 9034/AF shipping container for the fuel transfer to the RRF in a letter dated July 24, 1989.

The inspector informed the licensee that the intent was to operate at a steady state power level of 100% and that minor fluctustions which indicated power in excess of 100% were not considered to be indicative of steady state operation. It was noted that should the indicated power remain above the 100% indicated power level for any appreciable tin,e the power should be reduced.
The licensee's program in this area appeared to be consistent with their safety goals. No violations or deviations were identified,
- g. Records Review The following licensee records were reviewed:

to the Richland low level wast disposal site and Trojan Nuclear Power Plant. The licensee maintains records of R0 and SRO reactor operation. These records include Reactor Observation Record (required reactivity manipulations), Operator Observation Record (record sf operators performance during performance of various tasks). The requalific.tfon files of five student R0s and SR0s were examined. The records were adequate to demonstrate the accomplishment of the requalification training program. The Requalification Training Program was adequate to accomplish the l licensee's safety objectives. No violations or deviations were identified. : I
- j. Surveillance The inspector verified that the following surveillan reviewing licensee records:
TS F.5. The type and minimum number of safety circuits operable were as specified in TS Table I; TS F.6. The type and af,imum number of interlocks operable were as specified in TS Table II; TS F.7.

10 are use$ to perform environmental radiath . measurements in the reactor room and on the roof of the reactor facility. Exposures for 1988 and the first quarter of 1989 were reviewed. Results of the second quarter 1989 had not been received at the time of the inspection. All personnel exposures were less than 10% of the 1.25 rem / quarter limit specifiea in 10 CFR 20.101. A number of students with access to the f acility, including R0s and SR0s, were under 18 years old during the time period of the records evamined. The eaximum whole body lifetime exposure was 80 arem. The maximum extremity exposure recorded was 70 arem. The PICS, used by the licensee, were calibrated, using an NBS (NIST) traceable sealed source, by a member of the licensee's ROC. PICS found to be faulty were discarded. Since the last inspection the licensee had disposed of no radioac'.ive liquid waste under the reactor license. Due to the relatively low power of the RRF and the difficulty of integrating i under the curve of the stack gas monitor recorder, the licensee elected to evaluate gaseous effluer,ts using a different technique. For the September 1,1987, to August 31, 1988, annual report period, the licensee used the ratio of thermal energies of the RRF and the Oregon State University (OSU) TRIGA and the reported Argon-41 releases from OSU to estimate the release from the RRF. At the time of the inspection the licensee had not completed a similar or alternate calculation for the 1988-89 time period. For the last annual texrt the licensee's reported release using this method was 0.0608 Ci Ar-41. At the stack flow rate this was equivalent to an ( average release rate of 3.07 E-9 pCi/m1, substantially less than the ' l most restrictive value given in 10 CFR 20 Appendix B, 4 E-S pCI/ml.
- c. Surveys In addition to the contamination surveys performed by the reactor technician, recorded in the " Wipe Test Log Book", discussed above in report section 3.g., daily surveys are performed as a part of the "Startup Checklist". The results of these surveys were recorded on that form. The inspector observed an R0 and SRO removing samples from the " lazy susen" and monitoring samples discharged from the
" rabbit" irradiation system. The operators were using good cadiation safety practices and evaluating each irradiated sample with a survey instrument at a distance prior to approaching the sample closely.
The licensec's health physics practices appeared to be adequate to protect the health and safety o' the staff and the public. No violations or deviations were l entified.
- 4. Emergency Planning and Preparedness (40750)
The licensee maintained a complete copy of the Emergency Plan, - Implementing Procedures and the Emergency Call tist in the control room within arms reach of the operator. These documents were reviewed during

f,ICII"ED 1:RC REG 10M V E:l';;-7 C 9 34 July 31,1990 Mr.neodore Michaels Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, DC 20555 Re: License R-112, Docket 50-288
Dear Mr. Michaels:
he purpose of this k cr is to stipply infonnation required by 10CFR50.75 regarding assurances that funas will be available to decommission the Reed TRIGA Mark I Research Reactor. Currently, we have no plans t decommission the reactor. Therefore, for purposes of planning, we are assuming that the reactor operates to the expiration of its current operating license on 3 October 2007. We have determined the cost of decommissioning as of 1990 by consultation with Dr. J. Razvi, of General Atorr.ics, Professor J. G. Williams of the University oflifinois and individuals at Chem-Nuclear Systems. Based on these consultations we estimate a cost in 1990 dollars of 5500,000.00, which assumes retuming the building to a condition suitable for unrestricted use. In addition, Reed will make available a Senior Reactor Operator, to supervise the decommissioning, over a period of I-2 years. We have adjusted the present cost for inflation simply by assuming that the present inflation rate of 4.5* continues indefinitely, and have obtained a corrected cost of
$1,056,700.00, i.e. 2.1134 X $500,000.00, for the year 2007. If the extrapolation turns out to be unrealistic, we will adjust the inflation rate accordingly,in future estimates.
The funding method chosen by it,eed College is the prepayment method, where the College will establish an appropriate acciur.t with the First interstate Bank trust department here in Portland. Sincerety, James L. Poweil President
