ENVIFONFENTAL ASSESSMENT FOR THE TRAINING AND RESEARCH REACTOR OF THE UNIVERSITY OF MICHIGAN LICENSE N0. R-28 DOCKET N0. 50-2 Description of Proposed Action This Environmental Assessment is written in connection with the proposed renewal for 20 years of the operating license of the research reactor at the University of Michigan (UM) facility located on the North Campus of the University in Ann Arhor, Michigan, in response to a timely application from the licensee dated November 30, 1984, as supplemented. The proposed action would authorire continued operation of the reactor in the nanner that it has been operated since facility license No. R-28 was issued in 1957. Currently, there are no plans to change any of the structures or operating characteristics associated with the reactor during the renewal period requested by the licensee.

Need for the Proposed Action The operating license for the facility was due to expire in January 1985.

The proposed action is required to authorize continued operation so that the facility can continue to be used in the licensee's mission of education and research.

Alternatives to the Proposed Action As required by Section 102(2)(E) of NEPA (42 U.S.C.A. Q4332(2)(E)), the staff h3s considered possible alternatives to the proposed action. The only reasonable alternative to the proposed action that was considered was not renewing the operating license. This alternative would have led to cessation of operations, with a resulting change in status and a likely small impact en the environment. From the standpoint of environmental impact, there are no appropriate alternatives to the proposed action.

Environmental Inpact of Continued Operation The UM reactor operates in an existing shielded water tank inside an existing single purpose building attached to a multi-purpose building.

No new construction is associated with continued operation of the reactor and there is no change in reactor operating conditions or practices.

Therefore, this licensing action would lead to no change in the physical environment.

Based on the review of the specific facility operating characteristics that are considered for potential impact on the environment, as set _ forth.in the staff's Safety Evaluation Report (SER)y for this action, it is concluded that reneral of this operating license will have an insignificant environ-mental impact.

Argon-41, a product from neutron irradiation of air during operation, is

- the principal airborne radioactive effluent from the UM reactor during routine operations. Conservative calculations by tha staff, based on the total amount of Ar-41 released from the reactor during a year, predict a maximum potential annual whole body dose of less than 1 millirem in unrestricted areas. Radiation exposure rates measured outside of the i reactor facility building are consistent with this computation.

l The staff has considered hypothetical credible accidents at the UM reactor and has concluded that there is reasonable assurance that such accidents will not release a significant quantity of fission products from the fuel cladding and, therefore, will not cause significant radiological hazard to the environment or the public.

This conclusion is based on the following:

a) the excess reactivity available under the technical specifications is insufficient to support a reactor transient generating enough energy to cause overheating of the fuel or loss of integrity of the cladding, 1

l b) at a thermal power level of 2 Mw, the inventory of fission products in the fuel cannot generate sufficient radioactive decay heat to cause

, fuel damage even in the hypothetical event of rapid total loss of coolant, and

~

c) the hypothetical loss of integrity of the cladding of the maxinun irradiated encapsulated fueled experiment will not lead to radiation exposures in the unrestricted environrent that exceed guideline values of 10 CFR Part 20.

In addition to the analyses in the SER summarized above, the environmental impact associated with operation of research reactors has been generically ,

evaluated by the staff and is discussed in the attached generic evaluation.

This evaluation concludes that there will be no significant environnental impact associated with the operation of research reactors licensed to operate at power levels up to and including 2 ffWt and that an Environmentel Impact Statement is not required for the issuance of construction pernits or operating licenses for such facilities. We have determined that this generic evaluation is applicable to the continued operation of the UP reactor and that there are no special or unique features that would preclude reliance on the generic evaluation.

Agencies and Persons Consulted The staff has obtained technical assistance from the Los Alamos National Laboratory in performing the safety evaluation of continued operation of the VM facility.

Conclusion and Basis for No Significant Impact Finding Based on the foregoing considerations, the staff has concluded that there will be no significant environmental impact attributable to this proposed license renewal. Having reached this conclusion, the staff has further concluded that no Environmental Impact Statement for the proposed action need be prepared and that a No Significant Environmental Impact Finding is appropriate.

ENVIRONMENTAL CONSIDERATIONS REGARDING THE LICENSING-0F RESEARCH REACTORS AND CRITICAL FACILITIES Introduction This discussion deals with research reactors and critical facilities which

- are designed to operate at low power levels, 2 MWt and lower, and are used primarily for basic research in neutron physics, neutron radiography, isotope production,. experiments associated with nuclear engineering, training and as a part of a nuclear physics curriculum. Operation of such facilities will generally not exceed a 5-day we'ek, 8-hour day, or about 2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> per year.

Such reactors are located adjacent to technical service support facilities with convenient access for students and faculty.

Sited most frequently on the campuses of large universities, the reactors are usually housed in already existing structures, appropriately modified, or placed in new buildings that are designed and constructed to blend in with existing facilities. However, the environmental considerations discussed herein are not limited to those which are part of un'iversities. -

' ~

],

Facility ,

There are no exterior conduits, pipelines, electrical or mechanical structures or transmission lines attached to or adjacent to the facility other than,for.

utility services, which are similar to those required in other similar facilities, specifically laboratories. Heat dissipation is generally accom-plished by use of a cooling tower located on the roof of the buildhg. These cooling towers typically are on the order of 10' x 10' x 10' and are comparaule to cooling towers associated with the air-conditioning systems of large office buildings.

Make-up for the cooling system is readily available and usually obtained from the local water supply. Radioactive gaseous effluents are limited to Ar-41 and the release of radioactive liqu.id effluents can be carefully monitored and controlled. Liquid wastes are collected in storage tanks ,

to allow for decay and monitoring prior to dilution and release to the sani- l tary sewer system. Solid radioactive wastes are packaged and shipped off-site for storage at NRC-approved sites. The transportation of such waste is done in accordance with existing NRC-D0T regulations in approved shipping containers. "

Chemical and sanitary waste systems are similar to those existir.o at other similar laboratories and buildings.

Environmental Effects of Site Preparation and Facility Construction Construction of such facilities invariably occurs in areas that have already been disturbed by other building construction and, in some cases, solely within an already existing building. Therefore, construction would not be expected to have any significant effect on the terrain, vegetation, wildlife or nearby waters or aquatic life. The societal,' economic and esthetic impacts of construction would be no greater than those associated with the construction

~

of a large office building or similar research facility.

Environmental Effects of Facility Operation Release of thermal effluents Trom a reactor of less that 2 MWt will not have a significant effect on the environment. This small amount of waste heat is generally rejected to the atmosphere by means of small cooling towers. Ex-tensive drift and/or fog will not occur at this low power level.

Release of routine gaseous effluents can be limited to Ar-41, which is generated by neutron activation of air. Even this will be kept as low as practicable by using gases other than air for supporting experiments. Yearly doses to unre-stricted.. areas will be at or below established guidelines in 10 CFR 20,_ limits.

. Routin.e-releases of radioactive _ liquid. effluents can be carefully monitored and controlled in a manner that will ensure compliance witW current standards. Solid radioactive wastes will be shipped to an authorized disposal site.in approved '

cont'ainers. These wastes should not require more than a few shipping cordainers a year. _ . . . .

Based on experience with other research reactors, specifically TRIGA reactors operating in the I to 2 MWt range, the annual release of gaseous and liquid effluents to unrestricted areas should be less than 30 curies and 0.01 curies, respectively.

No release of potentially. harmful . chemical. substances will occur during normal cperation. Small amounts of chemicals and/or high-solid content water may be released from the facility through the sanitary sewer during periodic blowdown of the cooling tower or from laboratory experiments.

Other potential effects of the facility, such as esthetics, noise, societal or impact on local flora and fauna are expected to be too small to measure.

Environmental Effects of Accidents Accidents ranging from the failure of experiments up to the largest core damage and fission product release considered possible result in doses that are less then 10 CFR Part 20 guidelines and are considered negligible with respect to the environment.

Unavoidable Effects of Facility Construction and Operation The unavoidable effects of construction and operation involve.the materials used in construction that cannot be recovered and the fissionable material used in the reactor. No adverse impact on the environment is expected from either of these unavoidable effects.

~

Alternatives to Construction and Operation of the Facility To accomplish the objectives associated with research reactors, there are no suitable alternatives. Some of these objectives are training of students in the operation of reactors, production of radioisotopes, and use of neutron and gamma ray beams to conduct experiments.

~

Long-Term Effects of Facility Construction and Operation The long-term effects of research facilities are considered to be beneficial as"a result of the contribution to scientific knowledge and training. Because . u of the relatively small amount of capital resources . involved and the small impact on the . environment, very little irreversible and irretrievable commit-ment is~ associated with such facilities. -c --

~ ~ '

Costs ind Benefits of Facility Alternatives The costs are on the order 'of several millions of dollars with very little -

environmental impact. The benefits include, but are not limited to, some combination of the following: conduct of activation analyses, conduct of neutron radiography, training of operating personnel and education of students.

Some of these activities could be conducted using particle accelerators or radioactive sources which would be more costly and less efficient. There is no reasonable alternative to a nuclear research reactor for conducting this spectrum of activites.~~

Conclusion ,

The staff concludes that there will be no sig..!ficant environmental impact associated with the licensing of research reactors or critical facilities designed to operate at power levels.of 2 MWt or lower and that no environmental impact statements are required to be written for the issuance of construction permits or operating licenses for such facilities, i

TECHNICAL SPECIFICATIONS Ford Nuclear Reactor Docket 50-2, License R-28 November, 1984 Objective:

To specify the lowest acceptable level of performance or the minimum number of acceptable components for the reactor safety tf ttom And cther safety .clated i n s t r u.nen t a t i on .

Specification:

The reactor shall not be made critical unless:

(1) The reactor safety systems and safety related instrumentation are operable in accordance with Tables 3.1 and 3.2 including the minimum number of channels and the indicated maximum or minimum setpoints; (2) All shim safety rods are operable; (3) The time from the initiation of a scram condition in the scram circuit until the shim safety rods are fully inserted (release-drop time) shall not exceed 500 milliseconds; (4) Mechanical devices are installed which prevent the lifting of fuel elements through the movement of control rods.

Bases:

Neutron flux level scrams pros)de redundant automatic protective action to prevent enceedirg the safety limit on reactor poier. The period scram limits the rate of rise of the reactor ]

i power to periods which are manually controllable without reaching I excessive power levels or fuel temperatures.

• Power-flow coincident scrams provide redundant channels to assure that an automatic loss of flow scram will occur in the event of a loss of flow when the reactor is operating at power levels above 100 kw.

The rod withdrawal interlock on the Log Count Rate channel assures that the operator has a measuring channel operating and indicating neutron flux levels during the approach to criticality.

The core e: tit temperature auto rundown function and response of the operator to the pool level alarm assure that the reactor will not be operated above the safety limit for core inlet temperature and below the safety limit for pool level.

e. The personnel exit door located in the north ali c* thu W114ing A id LM : ;c.' I c c. . t e d a t h ee beamport floor which connects to the PML hot cave operating area will be clamped closed.

Bases:

The potenti al radiation exposure to persons at the operations boundary following an accident releasing fission products within the confinement building has been evaluated. The evaluation used a leakage rate from the confinement building of 10% of the building volume per day, and concluded that the accident doses would be acceptable. Confccmance to Specifications

3. 3. (1 ) and 2.0.(2) will assure that the building leak rate will not e.:ceed the leak rate used in the evaluation.

The 1.0 mr/hr setpoint for the facility exhaust radiation monitor provides a mechanism for isolating the bu11 ding ventilation system in the event of a sign 1+1 cant release of radioactive mater.a1 Into the reactor butiding. This setpoint, for the detector location involved. represents a gamma emitting nuclide concentration of 10-2 to 10-* microcuries/cc of building air.

By requiring that the access doors and equipment hatch romain closed, except for brief, attended pericds to permit personnel or equipment passage, the integrity of the confinement will be maintained at or below the value assumed in the Ha:ards Summa y Repcet, end the release of radioactive material will be minimi:ed.

0.4 Primary Coolant Conditions App 1tcability:

This specification applies to the limiting conditions for available pool water volume, primary coolant pH. resistivity, radioactivity, and flow distribution.

Objective To maintain the primary coolant in a condition to minims:e the corrosion of the primary ccolant system. fuel clad. and other reactor components, and to assure proper conditions of coolant for normal and emergency requirements.

Specification:

1

(1) The primary coolant pH shall be maintained between 4.5 l and 7.5.

(2) The primary coolant resistivity shall be maintained at a value greater than 200,000 ohm-cm e:: cept for periods of time not to e.Nceed 7 days when the resistivity may not be less than 50.000 chm-cm.

(3) For cperation at power levels in excess of 100 kw in the fceced convection mode. all grid positions shall contain fuel elements. reflector elements, grid plugs or e>: p er i men t al facilities.

(4) For operation at powers in e;: cess of 1 Mw. the pool gate must be in its storage location.

Bases:

Experience at this and other facilities has shown that the maintenance of priinary coolant system water quality in the rangen specified in Specification 3.4.(1) and 0.4.(2) will control the corrosion of the aluminum components of the primary coolant system and the fuel element cladding.

The requirement that all grid positions be occupied will prevent the degradation of flow rates due to flow bypassing the Acttve fueled region through an unoccupied grid pl. ate position.

The requirement that the gate be stored assures that the full vol.ime of the pool water is available to provide cooling of the core during normal operation and in the event of a losn of coolant ac:1 dent.

3. 5 Heavy Water Reflector Tank Applicability:

This specification applies to the heavy water reflector tant used in the reactor core.

Objective:

To assure that heavy water handling in the heavy water reflector tant does not jeopardt:e facility and personnel safety.

TECHNICAL SPECIFICATIONS Ford Nuclear Reactor Docket 50-2. License R-28 November, 1984 Specifications (1) The shutdown margin for the core shall not be less than 0.10 delta N/N whenever heavy water movements which can "m ' t te postta m -23ct: :t intcet.cr2 3r 'md art; t tr .

(2) The tritium content of the heavy water reflector tank shall be no greater than 50 curies.

bases:

The largest positive reactivity increase that can be produced by replacing light water with heavy water in the heavy water reflector tank is 0.04 delta K/K. Maintaining the reactor shutdown margin at no less than 0.10 delta N/K during heavy water transfers provides adequate margin to assure that the reactor will remain subcritical during heavy water transfers that could add positive reactivity.

The 50 curie limit imposed on the tritium content of the heavy water reflector tant in Specification 0.5.(2) assures that offsite concentrations of tritium in the event of a tank rupture will not onceed the limit established in 10CFR20 for tritium releases to uncontrolled areas.

0.6 Airborne Effluents Applicability:

This specification applies to the monitoring of airborne effluents from the FNR.

Objuctive:

To assure that containment integrity is maintained during reactor operation and that the release of airborne radioactive material from the FNR is maintained below the limits established in 10CFR20.

Bases:

1 The limits established in specification 3.6 (1) incorporate i a dilution factor of 400 for effluents released through the i eahaust stacL1. This dilution factor was calculated from actual l FNR site meteorological data and represents the Icwent dispersion factor determined and the ble) hest frequency of wind in any sector.

l Decause of the une of the most conservative measured values of l wind directional froquency and dispersion factcra, this dilutton f actor will assure that concentrations of radioactive material in i

unrestrictod areas around the FNR site will be far belcw the l limits of 10CFR20.
