Proposed Change No. 6' ! i ( , for-the
. Southwest Experimental Fast Oxide Reactor s
I. Introduction l. j Under the authority of License DR-15, General Electric operates the Southwest Experimental Fast Oxide Reactor at a site near Strickler, Arkansas. - A revision of the current Technical Specifications is desired as described herein. The applicable revised pages of the Technical l Specifications are also included as Attachment A. I i II. Proposed Changes Pursuant to the provisions of 10 CFR 50.59, General Electric requests that the SEFOR Technical Specifications be changed by substituting Pages 3.12-2, 3.12-3, and 3.12-5 in Attachment A of this document for j the corresponding pages of the current Technical Specifications. l These revisions will change the minimum allowable 20-inch travel time for the Fast Reactivity Excursion Device (FRED) from 0.085 seconds to 0.097 seconds, i III. Purpose of the Proposed Change l The purpose of this proposed change is to update the minimum allowable FRED 20-inch travel time so as to limit the maximum reactivity insertion rate of the super-prompt slug to 20 $/sec. IV. Discussion The present Technical Specifications limit of 0.085 see was the 20-inch travel time estimated to give a maximum reactivity insertion rate of 20 $/sec with a 1.3$ slug. This estimate was made prior to design changes in the FRED documented in Reference 1 and prior to in-reactor i i I l l (
- 1 l
' ^ r Q < slug position versus time and slug worth versus position measurements. l At the beginning of the transient test program such measurements indicatedtthat the minimum 20-inch travel time would hr.ve to be
. increased (Reference 2). '
As discussed in Reference 2, the reactivity insertion rate can be determined as a function of axial position of the poison slug during a transient from the following relation: dk dk dx de dx de . dk where gg- E reactivity insertion rate, dk gg E reactivity change per inch movement of poison slug as determined from slug worth versus position measurements. dx i gg- E poison slug velocity. The minimum 20-inch travel time of 0.097 sec, necessary to give an insertion rate of 20$/sec for a slug worth 1.30 dollars, has been determined by ratioing the rate which would have been obtained from the sub-prompt slug, if the poison section had been positioned 0.9 in. lower in the rod, a position that corresponds to the location of the poison section for the super-prompt slug. The sub-prompt slug worth with the poison section at this lower position would have been 101.1c. l Figure 1 gives the measured worth versus position characteristics of the sub-prompt slug. Figure 2 shows the slope, dk l gg, of Figure 1 and l also the FRED velocity characteristics as reported in Ref erence 2. The insertion rate that would be obtained by firing the sub-prompt slug so that the initial position of the poison section corresponds ! to the position of the poison section of the super-prompt slug can be determined by shif ting the velocity versus position curve for the sub-promp slug by 0.9 in., as shown on Figure 2. The reactivity l

t
. The insertion rates obtai'n ed by multiplying the velocity curves in ,
) Figure 2 by the dk/dx curve are given in Figure 3. The maximum *
( reactivity insertion rate determined in this manner is 14.4 $/sec. t , l As discussed in Reference 3, the dynamic worth (as determined from reactor response) of the sub-prompt slugs was 4% greater than the static worth. Therefore, the reactivity insertion rate of 14.4 $/sec, , and the alug worth of 1.011$, which are based on static slug measurements, are each increased by 4% to 15.0 $/see and 1.051$, respectively, for the determination of the reactivity insertion rate for a 1.3$ slug: I h 15.0 1
=
18.5 $/sec N i i The calculated reactivity insertion rate of 18.5 $/sec is based on a FRED 20-inch travel time of 105 msec. Smaller 20-inch travel times would yield larger reactivity insertion rates. Since the insertion l rate is approximately inversely proportional to the 20-inch travel time f or small changes in the 20-inch travel time, a travel time of j 97 msee yields an insertion rate of 20 $/sec. This rate provides significant margin with respect to the rate of 50 $/sec (with a j dk i sodi,um-out Doppler coefficient, Tg, of -0. 004) for which the safety of the plant has been assessed (Reference 4). ] i i ; l The average 20-inch travel time for the FRED is 105 msee with a i l statistical standard deviation of 1.7 msec (Reference 1). As dis-I cussed in Reference 1, page 11, a highly unlikely series of equipment malfunctions and bypassing of procedural controls would be necessary to substantially lower the 20-inch travel times. i l Therefore, the proposed limit of 0.097 see for the 20-inch travel 1 time can be met and will provide adequate assurance thct the maximum reactivity insertion rate will remain within safe limits.
