Introduction  !

By application for license amendment dated May 22, 1975, the University of California at Los Angeles (the licensec) requested changes to the Technical Jpecifications foi the UCIA Tr. lining Retetor. The changcr to the Technical Specifications involve (1) codified Argon-41 restrictions, (2) changes to the restrictions on in-core experiments, and (3) administra-tive changes.

In reviewing the application for license amend.t.cnt it was found that .

several changes were required in the proposed Technical Specifications. l These chan;,cs were discussed with and concurred in by the licensec.

Discussiori i

Discussions of the licensco's proposed Technical Specification changes 1 are contained in the following sections.

1. Modified Argon-41 (Ar-41) Restrictions . t

. The UCLA Training Reactor has a graphite moderated core in which f, the fuel is arranged in separate, water cooled, fuel boxes. During reactor operation the air which is located between the fuel boxes is irradiated producing isotopes of Argon (Ar-41), Nitrogen (N-16),

)l

. Of these isotopes, 0-19 and Oxygen N-16 have (0-19), and Carbon very short (C-14)/ (29.4 and 7.3 seconds, respectively) half-lives,_ 1 and C-14 exists in very minute quantities; Ar-41 however has a .

half life of 109 minutes and is present in sufficient abundance I to be a significant effluent. Air' conte.ining Ar-41 is drawn from '; ,

the reactor room by the ventilation system, filtered and monitored ';

! for radioactivity, diluted with fresh air and exhausted through an acceleration no::lc at the top of the facility stack. ,

d.,

MA "half life" is the ti'ne it would take for the radimetivity of a  :

i given isotope to decrease to 1/2 of its initial vclue.

1 L

In the application for license amendment dated May 22, 1975, the .,  !

licensee requested several changes to the Technical Specifid.ations addressing the production, monitoring, and release of Ar-41. The 'l requested changes are as follows: (1) Technical Specification '1 >

II.B.3 would be modified to state correctly the height of the facility stack with the acceleration no::1c removed. Removal of the

'l

, acceleration no::1c would establish a flow rate of 14,000 CFM .;

in conformance with the original Technical Specification, (2) "

Technical Specification V.P. would be changed to require the exhaust air to be moniroted only during reactor operation and during core  !

alterations. At the present time exhaust air cust be monitored +

"continuously". (3) Technical Specifications II.B.4 would be  !

changed and V.E. added to allow a reduction factor of 460 for allownble i concentrations of Ar-41 in the stack and releases to the atmosphere, i respectively. l

2. Changes to the Restrictions on In-Core Experirents Technical Specification III.E.3 states that "No sample shall be pneumatically,yenoved from a critical reactor if the resultant

, stable periods will exceed 20 reconds". This Technical Specification was incorrectly worded; the term "exceed" should have read "bc less than". In addition, the licensee has requested that this section be changed to reficct the additional potential for a transient, with a stable period of less than 20 seconds, which might result from the insertion of a sample into the reactor core.

3. , Administrative Changes The licensec has requested that a Technical Specification be added

. to be designated as paragraph VIII B which would assign the responsi-bility to the reactor supervisor for maintaining records of AR-41

/* releases. Additional administrative changes include substitution of "Nuclear Regvlatory Commission" for "Atomic Energy Ccamission" -

in Specifications VIII.K.4, VIII.L.2, and VIII.M.3.d; substitution - <

of "NRC" for "AEC" in VIII.M and VIII.M.1. , and substitution of p',

"USNRC" for "USAEC" in VIII.M.2 and VIII.M.3. These administrativv g'.

changes have no safety significance and will not be discussed further. .;

Evaluation '

Our evaluation of the licensee's proposed Technical Specifications is l!l g

contained in the following sections. --

2/ 1he stable period is the time it would take the neutron flux to change by a factor of 2.3.

i 1

1. Modified Ar-41 Restrictions

'Ihe effect of removing the acceleration no::le from the facility "

stack will be an increase in the gascous discharge rate fronispproxi- '

nately 11,200 CFM to approximately 14,000 CFM. This will res' ult  :

in a ccrresponding reduction in the concentration of Ar-41; thus, ,

we find proposed Technical Specification II.B.3 to be acceptabic. ,

We have reviewed the licensee's proposal to require exhaust air  !'

nonitoring during n actor operation and during core alterations, ,

as compared to the present requirements of Technical Specification "

V.B which requires "continuous nonitoring". Accidental radioactive l discharges could only result frca reactor operation or from nitorations i to the reactor core such as the movement of fuel or experiments; i thus', the monitoring of exhaust air during other than these times  ;

does not materially add to the safety of the facility. Accordingly, i proposed Technical Specification V.B is acceptabic. l The licensee has requested that we approve effluent release limits '

for Ar-41 in excess of those permitted by 10 CFR Part 20, Section 20.106 (a) . This request, submitted via license amendment dated llay 22, 1975 and supplemented by let ter dated November 5,1975, was made pursuant to 10 CFR Part 20, Section 20.106(b) . In the course of our review, we have made the following findings as required by 10 CF.; Part 20, Section 20.106(b) prior to our approval of increased release limits: (1) The applicant has made a reasonabic effort to minimi:e the r.'dioactivity contained in effluents to

, unrestricted areas. Various experiments involving the sealing of the reactor, use of an inert "sweep gas", and provisions for a i 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> delay time yicided only nodest results with regard to reduction '

of the Ar-41 effluent. The licensco has, however, committed to re-ducing the use of the facility to a minimum level. Ne have approved a reactor utill:ation factor of .188 for consideration of the effective concentration of Ar-41. (2) It is not likely that radioactive material ,

! / discharged in the effluent would result in the exposure of an individual i to concentrations of radioactive material in air or water exceeding -

the limits specified in 10 CFR Part 20, Appendix "B", Tabic II. .

In making this finding, we have considered the effects of atmosphe-ic ,

dilution and occupancy of the facility as follows: I' l facility stack is in a restricted area as defined by(al Since the10 CFR Pnrt 20, *'

i Section 20.3(a)(14), the licensee may take credit for a dispersion :j factor pursuant to 10 CFR Part 20, Section 20.106(d). h'e have 'I -

approved a dispersion factor of .115. The licensec has proposed an Environmental Program to be carried out over a two year period i to confinn the conservative nature of the dispers!:,.i factor. The b requirements of this prograr have been incorporated into the Facility -

Operating License as paragraph 2.C.(3); the associated reporting i

[ requirement are contained in Technical Specification }!.3.h. (b)

Ar-41. The combined effect of the reactor utilization factor, the l dispersion factor, and the occupancy factor yields a reduction

)

factor of 460. Accordingly, we find proposed Technical Specifications II.D.4 and V.E., which allow for a reduction factor of 460 for Ar-41 effluent in the stack and rolesses to the atmosphere, respectively,

- to be acceptabic. If any of components of the reduction factor a change over a period of one year so as to increase the effectue i value of the reduction factor, Technical Specification V.E. would .

1 require the licensee to so inform the Conmission. {

2. Changes to the Restrictions on In-Core Experiments J Technial Specification III.E.3 stntes thnt "No :tr.ple shall bc

~ '

8 pneumatics11y rc=oved from a critical reactor if the res011 ant  ;

4 stabic period will execed 20 seconds". This Specification is

. deficient for two reasons. First, the requirement for stabic periods to exceed 20 seconds is cicarly in error since transients yiciding shorter rather than longer periods are more ha:ardous in that they have the potentici of rapidly incrensing the reactor power. Secondly, this Spe:ification does not recogni:c the potent a1 for achieving a positive reactor period as a result of inserting a ss=ple in the i reactor. The proposed Specification III.E.3 requires that "No 3

sampic shall be pneumatically inserted or removed from a critical i reactor if the resultant stable positive period will be less than 4

20 seconds". This Specification corrects the two above referenced deficiencies and is acceptable. .

Conclusion ,

f. We have concluded, based on the considerations discussed above, that: i (1) because the changes do not involve a significant increase in the ,

probability or consequences ci accidents previously considered and do ~

not involve a significant ha:ards consideration, (2) there is reasonabic assuranec that the health and safety of the public will not be endangered by operation in the proposed manner, and (3) such activities will be ['

e i

j conducted in compliance with the Commission's reguistions and the issuance !j of this amendment will not be inimical to the cocnen defense and security V j or to the health and safety of the public. ,
