9 (Contention I).
9 10 The information requested is contained in the report 11
" Class Use of the UCLA Reactor" which is appended to these 12 Supplemented Responses as " Exhibit A."
13 14 Supplemented Response to Interrogatory No. 35 (Con-15 tention II).
16 See the supplemented response above.
17 18 Supplemented Response to Interrogatory No. 29 (Con-19 tention II).
20 See the supplemented response above.
21 22 Supplemented Response to Interrogatory No. 42 (Con-23 tention II).
24 Actual run time was 381 hours0.00441 days <br />0.106 hours <br />6.299603e-4 weeks <br />1.449705e-4 months <br />.
25 26 I Supplemented Response to Interrogatory No. 46 (Con-27 tention II).
28 See " Exhibit C" attached to " Applicant's Further
1 Answers to Intervenor," dated June 11, 1981.
2 3
Supplemented Response to Interrogatory No. 20 (Con-4 tention III).
5 The definition is given in item 1.16 of the proposed 6
technical specifications.
7 8
Supplemented Response to Interrogatory No. 43d (Con-9 tention III).
10 The procedures are available in the control room.
11 Emcrgency procedures are posted in the control room and many 12 other places within the facility.
13 14 Supplemented Response to Interrogatory No. 9a (Con-15 tention IV).
16 Applicant did not consider the " failures or malfunctions" 17 as reportable occurrences.
18 19 Supplemented Response to Interrogatory No. 20 (Con-20 tention IV).
21 Not to Applicant's knowledge.
22 23 Supplemented Response to Interrogatory No. 8c (Con-24 tention VI_).
25 The data and its interpretation were discussed in the 26 1978 Annual Report to the Commission.
27 28 Supplemented Response to Interrogatory No. lla (Con-tention VI).
I._
i
W 1
The " validity" and " accuracy" relate to the instrument.
2 The instrument was correctly recording data.
-However, it was not 3
the data that was expected, since Applicant had not anticipated 4 j that the readings would be af fected by the concrete.
The 5
accuracy question was discussed in a report to the Commicsion 6,
titled "The UCLA Reactor is Safe."
Applicant has no doubts about 7
the validity and accuracy of its TLD data.
8 9
Supplemented Response to Interrogatory No. 25a (Con-10 tention VI).
11 The location was 4150 center Street, Culver City, 12 California.
13 14 Supplemented Response to Interrogatory No. 36c (Con-15 tention VI).
16 The Application for Amendment 10 chose utilization of 17 the conference room as occupancy limiting.
In-transit and 18 clevator waiting periods were assumed to yeild occupancy of 19 five months for each hour of conference room utilization (25 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> per week), or less than 5 percent of the 45 hour5.208333e-4 days <br />0.0125 hours <br />7.440476e-5 weeks <br />1.71225e-5 months <br /> work week.
21 (See Safety Analysis of Amendment 10, May 16, 1975.)
22 23 Suppleme..ted Respvase to Interrogatory No. 40 (Con-
)'4 tention VI).
20, a.
Penetration of concrete walls and floors was l
26 '
neglected.
This was a simplifying assumption based upon the high 27 attenuation of gamma-rays in concrete and the opinion that a 28 sabstantial transport of radiation would require cblique rays of long path length. -
e 1
b.
The shielding effect of partitions was assumed to 2
be zero.
3 c.
Because it was assumed to be negligible.
4 5
Supplemented Response to Interrogatory No. 41b (Con-6 tention VI).
7 Occupancy can reach 100% only if the same individual 8
or group occupies the area continuously for all hours that the 9
reactor might operate.
The occupancy factor assumed is the largest 10 one for any specific individual or group exposed; it is not the 11 summation of the occupancy factors of all groups exposed.
If 12 another particular group or individual is determined to occupy 13 th'e area a greater amount of the relevant time period then that 14 group or individual's occupancy is used to calculate a new 15 occupancy factor.
16 17 Supplemented Response to interrogatory No. 47a (Con-18 tention VI).
19 Relevant information requested can be found on the same 20 page of the same document cited in the interrogatory.
As ex-21 plained there the distance "r"
from the plume center line to 22 location "G" is stated to be 8.59 meters.
23 24 Supplemented Response to Interrogatory No. 9c (Con-25 tention VII).
26 Applicant schedules monthly meetings to discuss 27 operating procedures.
28 -
cs
1 Supplemented Response to Interrogatory No. 7d (Con-2 2
tention VIII).
3 The fission products identified in the application, 4
page III/B-3, are iodine, bromine and krypton isotopes.
The 5
longest lived fission product of each of these species which 6
might reasonably qualify as "a short-lived isotope" is" 7
I-131 -- 8. 04 days 8
Br-83 -- 2.40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> 9

Seven half-lives of I-131 is 56 days.
12 13 Supplemented Response to Interrogatory No. J8 (Con-14 tention VIII).
15 If the question pertains generally to a core inventory 16 "that can be contained," Applicant submits that all fission 17 products can be contained up to, and well beyond, the burn-up 18 of available excess reactivity.
If the question pertains generally 19 to a core inventory that may actually exist, then the most 20 relevant information is contained in NUREG/CR-2079
(" Analysis of 21 Credible Accidents for Argonant Reactors").
That report contains 22 a table listing some of the isotopes specified in the question.
23 The table describes the volatile constituents in one fuel 24 e2ement following continuous operation at 100' kw for one year.
25 26 II.
CONCLUSION 27 28 Applicant is continuing to derive information to '
e w-w
1 { respond to certain other questions of Intervenor's Second Set 2
of Interrogatories and will supplement its responsen further as 3
soon as it has obtained the information.
