Facilit y License R-80; Docket 50-157: Request for a License Amendment to withdraw NRC authorization to operate the Cornell TRIGA Reactor

Reference:

Letl:er from Cornell University to Document Control Desk, U.S. NRC, dated 8/13/2001

Dear CommissiiDner:

June 24, 2003 The Board of Tirustees of Cornell University voted on May 25, 2001, to accept the recommendationn of President Hunter R. Rawlings to close the Ward Center for Nuclear Sciences and to decommission the nuclear reactor associated with the Center.

Consequently, ("ornell hereby requests that its Facility License R-80 be amended so as to withdraw U.S IN Tuclear Regulatory Commission (NRC) authorization to operate the subject reactor.

On July 1, 2002! the Cornell TRIGA Reactor ceased to operate as a user facility and since that time the TI IGA has been used solely for operator requalification and for reactivity measurements,; all at powers of less than 10 watts.

In support of the eRequest for License Amendment, the following actions and changes to the license and 1to the Technical Specifications contained in Appendix A of the license are proposed:

1. Change the portion of section 2.B.2 of the license, " possess and use" to "possess but not use
2. Delete C I. in its entirety.
3. Change the portion of section C. 2. of the license, "as revised through Amend1' pent No. 8" to "as revised through Amendment 13".
4. Propose s changes to Technical Specifications are attached herewith.
5. A propq fed revision to the Operator Requalification Program is attached herewiti 1.

(In items 4 Emd 5, text deletions are marked by strikethroughs, and text additions are in italics.)

In support of th e subject request the following safety issues are addressed:

f\O2S

1. Assurance that the reactor will remain subcritical.

On 4/22/2003 reactivity measurements showed that 83 fuel rods were required to achieve criticality, cold clean, with all control rods withdrawn. For assurance that the reactor is maintained in a subcritical state, all fuel rods have been removed from the B, C, and D rings of the TRIGA grid plate with no more than 46 fuel rods stored in the E and F rings of the grid plate. With this configuration the shut down margin is 34.00$. Of a total of 122 fuel rods at Cornell, the remaining 76 fuel rods (nineteen (19) fuel rods stored in each of four (4) approved storage racks) are located in the reactor pool. For further assurance that the TRIGA will be maintained in an inoperable state, Cornell will disconnect power to the control drive units.

The fuel rods at Cornell are handled with a long flexible handling tool provided by General Atomics. When not in use the handling tool is stored in a locked room, the door of which is equipped with an intrusion detection system described in the Cornell Physical Protection Plan.

2. Adequate operating staff.

The present operating staff consists of two Senior Reactor Operators and one Reactor Operator, which is sufficient to handle equipment maintenance and surveillance requirements specified in the Technical Specifications.

3. Radiation protection.

Radiation monitoring equipment, with the exception of the Argone-41 monitor, will be maintained in accordance with the revised Technical Specifications. Radiation monitoring of personnel will continue with film badges and pocket dosimeters.

4. Physical security The physical security of Ward Lab is maintained by the Cornell University Police as specified in the Physical Protection Plan for Ward Lab. The number of surveillance and inspection tours by the Cornell Police has been increased since 9/11/01.

Cornell University appreciates your assistance in considering this request and is hopeful of an expeditious approval. If you have any questions or require additional information, please do not hesitate to contact me.

Sincerely, Mr. Howard C. Aderhold Laboratory Director

Amendment No. 9 3

2.0 SAFETY LIMITS AND LIMITING SAFETY SYSTEM SETTINGS Apicheability: is specification applies to the fuel element temperature.

Objetfive: The objective is to define the maximnum fuel element temperature tha can be permitted with confidene that no fuel element cladding damage will result.

Specification: The temperature in a stainless steel clad, high hydride fuel element shall not exceed 1,000 GC under any conditions of operation. The temperature in an aluminum cladI low hydride feel element shall not exceed 530 VOunder any conditions of operation.

Bases: The important process vaniable for a TRIGA reactor is the fuel element temperature. This parameter- if well suited as a single specification, and it is readily measured. A loss in the integ t of the fuel element cladding could arise from an excessive buildup of pressure between the fuel moderator and the cladding. Thc pressure is caused by the presence of fission product gases and dissociation of the hydrogen and zirconium in the fuel moderator. The magnitude of this pressure is determined by the fuel Thc safety limit for-the high hydr-ide (r fucl elements is based en data presented in the '"Hazafds RepoA for_ the Oregon St rt 250 kW"TRIGA MAK H Reactor," General Atomc Report GAA 6499, June 1965, first paragraph of Section 4.7, which indicates that the stress in the cladding (resulting from the hydrogen pressure from the dissoeiation of the zirconium hydride) will remain below the rupture stress proUded the tempernaue of the fuel does not exceed The temperatuire a which phase tFansitions that may lead to cladding failre in aluminuma clad low hydride fuel elements is reported to be 530 C6; references: "Tcehnical Foundations of TRIGA, "GA 71 (1958). pp. 63 72; also in "Hazards nalysis forTthe Oregon State University 250 I klW TRIGA Mark II Reacter," (June 1965), section 4.7. There is also extensive eperating experience with aluminum elad low hydride fuel; for example, with the Michigan State University TRIGA, wh4;-icsh was -icensed froma 1971 to 1981 to operate with a mixed corze of stainess steel clad high hydride and aluminum clad low hydride elements at 250 kW and up to 2$ pulses.

2.2 Limiting SafeQ. C. SCste.

Applioability: This specification applies to the trip setting for the fuel element temperature channel.

Obetgfive: The objective is to pre; nt th safetAlimit froem being exceeded-.

Specifications: For a cor-e compsed of stains stelad, high hydride fuel elements, limiting safety system settings apply aeoerding to the location of the standard theeocouple fuel element as indicated in the following table:

Amendmet No. 9 4

Location Limiting Safety System Settings B r-ing 60000 C ring 55500 D ring 1800 0 E ring 380 06 For-a cor-e conftainfing an aluminum clad low hydr-ide thermocouple fuel element (i.e., for-restricted mode operation) the limiting safety system setting for that element shall be 230 0 -f wit the elemenft located in the B ring.

_ae: Por-stainless steel clad, high hydr-ide fuel elements, the limiting safety system settings r-epresent-values of the temperature, which if exceeded, shall cause the reactor safety system to initiate a reactor scram. Beeause the fuel element temperature is measured in a single fuel element designed for this purpose, the limiting settings are given for different locations of that element in the core. It is assumed that the maximum fuel temperature is produced in the B ring.

For the stainless steel clad, high hydride fuel elements, the margin between the safety limit of 1,000 0&

and the limiting safety system setting of 600 C6 in the B ring was selected to assure that conditions would not arise whih would allow the fuel element temperature to approach the safety limit. The safety ma of 400 V allows for differences between the measured peak temperature and calculated peak temperature encountered in pulse operation of TRIGA reactors and for uncertainty in temperature channel calibration.

During steady state operations, the equilibrium temperature is determined by the power-level, the physical dimensions and properties of the fuel elements, and the parameters of the coolant. Beeause of the interrelationship of the fuel moder-ator- temper-ature, the power- level, and changes in r-eactivit r-equired-to-increase or maintain a given power level, any unwarranted increase in the power level would result in a relatively ,lo inces i. the fuel mo.derator_ temperatre. The mri between the maimium setting and safety limit would ensure the reactor being shut down before conditions could result that might damage the fuel elements.

For the aluminum clad, low hydride element the margin of 300 C between the safety limit of S C and the limiting safety system setting of 230 PC in the B ring was selected to assure that conditions would not ar-ise which would alloev the fuel element temperatre to approeach theI safety limit. The margin is large enough to allow for differences in properties of all aluminum I clad, all stainless steel clad, and mixed cor-es and for-uncertainty in temperaur-e channel ealibreaion.

Amendment No. 9 5

3.0 LIMITING CONDITIONS FOR OPERATION Applicabilitv: These specificatiens apply to the reactivity condition of the reactor, and to the reactivity worth of control rods and experiments, and to both modes cf reactor operation. Reactivity limits on experimefns are specified in Section 3.8.

Objectives: The objectives are to ensure that the reactor can be shut down at all times and to ensure that the fuel temperate safety limit will not be e-xceeded-.

Specification: The reactor shall not be operated unless the following conditions exist:

(1) The reactor is sub critical by more than 0.50$ when in the cold, xenon free condition, and (a) the highest worth control rod is fully vithdrawn, (b) the highest worth non secured experiment is in its most positive reactive state, and (o) secured experiments with movable parts are eaoh in their most feaetive state.

(2) The reactivity with all control rods fully withdrawn is known to be less than 4.00$ when the reactor is celd and xenon free and no experiments that affect reactivity are in place.

(3) When operating in restricted mode operation, the reactivity with all control rods fually witdrsvaw is less han 2.00$ with- vor witout experients in place.

Base: The shutdown ed by Specification 3.1 (1) is necessary-so that the reactor can be shut-down from any operating condition and remain shut down after cooldown and xenon dcoay, even if one contrel rod (including the transient control rod) should remain in the fully withdr-awn position.

The values ehosen are intended to limit the fuel temperature to <1,000 C for the stainless steel clad fuel in th event of inadverent or accidental pulsing of the r-eacteor.

The value chosen for (3) is intended to limit the temperature of the aluminum clad element to I e4530'C in the event of inadvestft or-accidental pulsing of the reactor.

3.2 Steaft State Opercation A bs _ig+ i ap t e ot e at h steady state p A levels.

(2) The reactor shall not be operated in the operated in the steady state mode at power levels above 10 k-W unless, in addition to the conditions of Section 3.1, the transient rod is thly withdrawnA.

Bases: The Cornell TPJGA Hazards Analysis (Supplement 1, 1980) is based on power levels up to 500 At power levels of 10 kW or below, the steady state fuel temperature is smail compared to the temptwaer rise caused by a pulse of 3.00$ or less.

When our-test proegr-am for initial oper-ation above 100 kW power-was conducted in F-ebruary March 1981, thermocouple measurements showed that at 200 IcW the B ring fuel temperature I for the all stainless stee clad high hydride core was 160 Bc. En when allowing for differences I resulting from the substitution of an aluminum clad low hydride element, the fuel temperature l at 200 kW will be farf below the safety limit4 of 53 0 BC.

3.3 Pulse Operationi-Applicability: These specifications apply to operation of the reactor in the pulse mode.

Objective: The objective is to prevent the fuel temperature safety limit from being exceeded during pulse moedc operation-.

Spcoifications: The reactor shall not be operated in the pulse mode unless, in addition to the requirements of Section 3. 1, the following conditions exit:

(1) The transient rod is set such that the reactivity insertion upon its withdrawal is equal to or less than (2) The steady state pewer-leoe ef the reactor is not greater than 10 kW.

The neutron detectors ensure that measurements of the reactor power level are adequately covered.

The radiAtion monitors provide infomation to operating perAsonel of any impending orAexisting daner from radiation so that there will be sufficient time to evaouate the facility and take the necessary steps to pre.vent the spread of radioactivity to the surrounding environment.

The specification on the sta+tp channel count rate is Ainteded to ensure thAt sufficient neutrons are available in the cor-e to pr-ovde a signal a the outpt of the startup channel during approaches to-cr-iticality.

The objective is to ensure that the ventilation exhaust shutdoen system is operable to mitigate the consequences of the possible release of an unconfolled amount of radioactive mater+ials toA unrestricted areas resulting from reactor operation.

Spcoifications: The reactor shall not be operated unless the ventilation system (including its shutdown mode) has been shown to be operable. Pn exception may be made for periods of time not to exceed 2 days to peJ t repairs to te system. During suc periods of repai (1) the r-eactor- shall nt be operated in the pulse mode and (2) the reactor shall not be operated with experiments in place *vhose failure could result in the release of radioati.e gases or aerosols.

Bases: The specifications governing operation of the reactor while the ventilation system is undergoing repair_preclude the lke-ihoo of;fue Al clement failue during such times. It is shown in Section 7. of FSAR that, if the reactor were to be operating at Ml steady state pover, feel element failure wvould not

+te occur even if all the reactor tank water were to be lost immediately.

VVV LmtationXW]s on EV Vr-imea;s, Applicabilitv: This specification applies to experiments placed in the reactor and its experimental facilities.

Objectives: The objectives are, in the event afan experiment failure, to lirit reactivity excursions that might cause th fuel temperature to exceed the safety limit, to prevent damage to the reactor, and to prevent excessive release of radioactive materials.

Specifications: The reactor shall not be operated vAth experiments in places that do not meet the follwing specifications:

(1) The reactivity worth of any individual exper-iment shall net exceed 2.00$-.

(2) Pny experimnent with a raeativit worth greater-than 1.00$ shall be securely fastened (as defined in Section 1, Secured Experimnent).

(5) The rate of planned reactivity addition in any experiment shall be less than 0.07$/sea, except that if the total associated reactivity addition is less than 0.10$, nc limit on the rate shall be imposed.

(6) The estimate of reactivity worth of an experiment shall be based insofar as possible on experimental infrmation. If the stimated worth is gater than 0.0$, the actu worth shall be measured and recorded at the time of insertion of the experiment; if the actual value significantly exceeds the estimate, the experiment shall be removed pending review and re approval.

(7) No experiment shall be conducted that causes local boiling of the core water.

(8) No experiment shall be conducted that causes intefferenee with conftrol rods or shadowing of reactor confro minstmentation.

3.10 Reactor Pool Water Aplicabilit: This specification applies to the water-eanm+ iined in the Cornell TRIGA feaetefneat.

Amendment No. 9 11

Objective: The objective is to set acceptable limits on the water quality, temperature, conductivity, and level oft rerthe -^ pool wate.n Speeifioations: The Cornell TRIGA shall be placed ini thle sudw condition if--

(1) the water temperature exceeds 130 F (2) the water conductivity is greater than 5 umho/cm except that during maintenance it may exceed that level for no longer-than I wccks.

(3) the water level above the core is below 18 1/2 ft., as measured from the top of the core.

Bases: The water temperature of the reactor pool is limited by the resin used in the mixed bed deienizer.

High water conductivity over a prolonged period indicates possible corrosion, demineralizer degradation, or slow leakage of fission products.

A r-eaeter pool level of 18 1/2 R. is adequate to provid'ing shielding during power-operatlions.

3.11 RestRieteA od- O -ation hydride thermocouple clement in the B ring and no stainless steel clad high hydride thermocouple 4 element in the core.4 Objective: The objective is to define the conditions under which restricted mode operation of the 4 reactor is permtted and the additional restrictions and specificationas whih that moc requires arc to be in foree. 4 4

Svecifications: Restricted mode operation shall be the only permissible mode of operation when nc operable stainless steel clad high hydride thermocouple element is available for use in the core.

When an operable stainless steel clad high hydride thermocouple element is available for use in the core, restricted mode operation shall not be used except that during tests of the cladding integrity and sm s f the worth of that element which require reactor operation without that element in the core the restricted mode shall be used.

Bases: The specifications of conditions under which restricted mode operaticn shall be used limit use of that mode to situations in which operation without a stainless steel clad thermocouple I element in the core is necessary for brief periods for test purposes or for continuity (though at a redueed scale) of programs using the reactor. The limits and restrictions required under the l restricted mode make it extremely unlikely that temperatures approaching the safety limits of any element in the core could occur.

ProposedRevision Cornell University Ward Laboratory OPERATOR REQUALIFICATION PROGRAM Revised and Approved June 16, 1992 I. Purpose The purpose of the Operator Re-qualification program is to meet the requirements of IOCFR55.59 while recognizing (in the spiit of !OCFR55.59(r)(7)) the special nature of a university research reactor, which has a limited scale of operation and a small staff the recent decision to permanently cease reactor operations. Therefore, the program is revised to reflect the change in operatingstatus by removing sections related to reactor manipulations. This is a continuing program of documented retraining and evaluation of licensed operators and senior operators; while the program's schedule is moderately flexible, it will be completed on a biennial cycle.

II. Overview of FacilityActivities With the permanentshutdown of the Cornell University TPJGA reactor, the scope of routine duties and tasks to be performed by a licensed Reactor Operators/SeniorReactor Operator (ROIRSO) at the Cornell University Ward Center for Nuclear Sciences (CU-WCNS) must be reduced to reflect the amended license conditions. Accordingly, ROISRO participationin facility activities at the CU-WCNS under POL license status shall include the following:

a) Maintenance, monitoring, and surveillance of t he TRIGA pool utilizedfor the interim storage of spentfuel elements.

b) Review of the proper use of the Fuel Handling Tool; as described in the General Atomics MaintenanceManual, GA-2555, in particular, sections 2.4 and 5.1, and Cornell University TRIGA Operating Procedures, OP-400, "Fuel Handling and Transfer Operations".

c) Annual review of Operations, Surveillance, and Health Physicsprocedures.

d) Annual review of the NRC approved Emergency Plan (EP) and Emergency Procedures (EPIPs)for Ward Laboratory.

1

e) A nnual review oft he operation, maintenance, and calibration requirements of the Area Radiation Monitors (ARMs) and the Continuous Air Monitors (CAMs) and Security Alarm System.

fi Review of changes to all CU-WCNS procedures, applicable regulations, and license amendments.

Im. General Conduct of Program Each biennial cycle of the program will include: (1) a pre-examination study and review phase consisting of individual study by licensees; (2) a written examination of a scope of level equivalent to examinations previously given here by examiners from the Operator Licensing Branch of the NRC; ( 3) systematic observation and evaluation o f operators during reactivity manipulations and simulated emergencies; and (4) for any operator displaying a deficiency in any category, accelerated retraining by tutoring and individual study, followed by re-examination or re-observation, in the deficient categories. A severe deficiency will result in suspension of the operator from licensed duties, with resumption of such duties only after retraining and satisfactory demonstration of competence.

The re-qualification cycle will be scheduled over two years in a manner that meets NRC goals of continuing competence and re-qualification of operators and at the same time avoids undue interruption of operating and other activities Onenieensed) for which members of the small staff of a university research reactor are responsible.

All licensed operators and senior operators will participate in each biennial cycle, regardless of the outcome of previous evaluations, with the sole exception of the Reactor Supervisor (see Section IV, Special Conditions).

The individual responsible for the re-qualification program will be the Reactor Supervisor.

Written records will be maintained of study materials, examinations, observations, evaluations, and training schedules.

IV. Details of Program I.Study and Written Examination Under the amended POL conditionsfor the CU- WCNS TRIGA reactor, operationof the reactor is not recognized. Licensed authorized activities for the ROISRO shall necessarily be limited tofuel handling activities. Accordingly, in each biennial cycle, the study phase and written examination for reactor operator and senior reactor operator licensees will include material from each of the following categories and shall conform to the requirements of 10CFR55.59(c)(2).

2

A. Reactor Theory, Thermodynamics, and Facility Operating Characteristics B. Normal and Emergency Operating Procedures and Radiological Controls C. Plant and Radiation Monitoring Systems These categories have been chosen to be in conformance with NUREG-1021 (Rev.6), NRC Examiner Standards, which reflect written examination guidelines for non-power reactors.

In keeping with the scale of operations and the limited size of operating staff, the biennial written examination will be scheduled in the fall of every other year and may be administered in section over a period not to exceed two weeks. The sequence will be: (1) the individual responsible for the requalification program will select and organize study materials and plan tutoring; (2) after a suitable study and review phase, all operators will be given the closed-book written examination; (3) the examinations will be graded and evaluated by the Reactor Supervisor; (4) an overall score of 70% is the minimum passing grade for the requalification exam; (5) any operator passing the requalification exam but receiving a score of less than 80% in any category will be required to undergo accelerated tutoring in such areas; (6) any operator scoring less than 70% overall shall be prohibited from performing licensed duties and must undergo accelerated tutoring and re-examination in all categories in which he scored below 70% before being considered for permission to resume licenseed duties. Such permission shall be given only after (i) his overall score after re-examination is 70% or greater and (ii) his resumption of licensed duties has been approved by the Reactor Supervisor. If a re-examination is required, it will be administered in the same manner as a normal requalification exam.

I. Reactiv.tytw langrlpulacns On a semiannual basis, the operating experience of each licensee will be reviewed with regard to the number of control manipulations he has performed or directed over the previos sixmonthi pefiod. These contol manipulations will eonsist the applibe reactivity marepulations specified in 10 C-FR 55.59()(3)(i), wvhih include reator-start ups, shutdowns, or other control manipulations which demonstrate skill and/or familiarity ith raeatfivt eentroel systems and prM rs. The purpose ef the enal re will be to assure that no less than ten such manipulations are completed by each licensee in a distributed fashion over each biennial requalification period.

3. Oeprertor Performance and Evaluatio Not less than twice each year, the performance and competence of each licensee will be observed and evaluated during a setof reatiity manipulations. The manipulations wi11 include a minimum of fe of the mniulaionas s peeified i n 1 0 CFR 5 5.c5(a)(2) 3

through (I13), as applicable to a univer-sity research raeator-. The observations will include a discussion of the licensee's actions and responsibilities during simulated emergency conditions. if an actual emergen oecun, the action of the operator on duty will be evaluated regardless of direct obsenr.ation.

Any operatr whose evaluation indicates a signtf;ar deficiency in manipulative skill, in lmvo.ledg of operaing or emergency prcedures, or V- i- ations re-sponding t emergency conditions will be prohibited from peffoiming licensed duties and will be required to undergo tutoring and re observation before being considered for penmission to resume licensed duties. Re evaluation at a sAtisfateory level and approval of the Reacto SupervAsor shall be required before resumption is permitted.

The evaluations of the licensee's performance will be included in his files.

4. Retraining Study Materials A complete set of study and reference materials will be provided for use by the licensees during their retraining program. It will be the responsibility of the Reactor Supervisor to review regularly the contents of these reference material to ensure that they are adequate and that they accurately incorporate changes in procedures, facility license and technical specifications, and facility design characteristics. Furthermore, whenever such changes are made, all licensed operator shall be informed of the changes in timely manner. These materials shall include a minimum of the following items:
1. A suitable general reference text on reactor physics.
2. Copies of the operating procedures.
3. Copies of the Technical Specifications.
4. Copies of emergency procedures.
5. Copies of the facility license and amendments thereto.
6. A summary description of facility characteristics.
7. Building and control drawings for the facility.
8. Copies of 10CFR20, 50 and 55.
9. Reference material on health physics principles and techniques.

V. Special Conditions

1. The Reactor Supervisor will be considered as having met the requirements of all evaluation portions of the re-qualification program because he will have participated directly in conducting all aspects of each biennial re-qualification program. The Reaeteo Supervisor will be required to perform the manipulations specified in Section fi.3 of the re qualification program.
2. An operator whose license is due for renewal while he is in a re-qualification program will be provided with a letter of certification indicating that he is currently enrolled in the re-qualification program. The letter of certification will indicate the anticipated date when that re-qualification program will be completed for the individual.

4

3. All licensed facility personnel who do not participate in facility operation for three or more months will be given an oral examination on facility and procedure changes and perform a reactivity manipulation and complete a minimum of six hours of on-shift functions under the observation of the Reactor Supervisor (or a senior operator designated by him) before being reassigned regular operational duties at the facility provided he is up to date on the biennial written examination. The results of the oral and performance examination provide the basis for re-certification of competence to the NRC as required by 10CFR55.53(f).
4. Successful completion of the initial NRC licensing examinations may be used to satisfy the licensee's biennial retraining requirements if appropriate. Such an individual's retraining program would be started with the next study phase and written examination scheduled at least 6 months after the licensee's initial licensing date.

VI. Records The following records will be retained at the facility for a period of five years:

1. Copies of retraining study materials and schedules.
2. All question sheets and graded papers for examinations and required reexaminations which were taken by each licensee during each of the re-qualifications periods.
3. The evaluation and summary review record of examinations and reexaminations of each licensee.
4. Summaries of control manipulations for each licensee.
4. The record of observations and evaluation completed when observing the operating competence of each licensee.
