Affidavit of Jacques Read, Anton Sinisgalli, and Charles Ferrell Concerning Texpirg's Mction for Sunmary Disposition Dated August 6, 1980 (Texpirg AC 50)
We have evaluated Texpirg's statement of material facts on radiaticn damage to electronic corponents and makes the following findings:
1.
Radiation Levels Required to Produce Electronic Malfunction " Latching" Electronic systems respond to radiation basically in two ways:
(1) permanent effects which are dependent upon total integrated dose degrading the electrical characteristics of the individual electronic piece parts, and (2) transient effects which are dependent upon the rate at which the radiation is delivered manisfesting itself as a spurious or false electrical signal.
2 The text %adiation Ef fects on Electronic Systems" by Henning L. Olesen indicates that a pulse of gamma or x-rays or charged particle radia-5 tion with a dose rate greater than 100,000 (10 ) rads /sec is required to cause semiconductor devices to be affected. This reference also provides in Table 6-1 a list of approximately 20 electronic components with their radiation dose sensitivity. The minimum total dose which is required to produce changes in the operation of these components is 6
greater than 10 rads.
2.
Radiation Levels During Normal Plant Operation a.
The natural background level (on the ground) in the vicinity of the Big Rock Point reactor in Michigan (Cited by Texpirg in R.E.~ Webb's text "The Accident Hazards of Nuclear Power Plants")
is approximately 89 mrem / year (10.3 x 10-6 r/hr) of which 36 mrem / year (4.1 x 10-6 r/hr) is due to cosmic radiation.

2-4 b.
An aerial survey by a low flying special radiation equipped 4
monitoring aircraft over the Big Rock Point nuclear reactor in i
1975 during normal plant operation indicated a maximum plume
-6 radiation level of 9 to 11 x 10 r/ hour, Commercial aircraft are designed to operate safely at high c.
a altitudes in the range of 20,000 to 40,000 feet. The co:,mic radiation levels at these altitudes are of the order of 60 x 10 r/ hour to 600 x 10-6 r/hr respectively.

~0 polar flight from California to Europe at high altitudes and the higher cosmic ray intensities at high latitudes would I
result in a total dose of 5000 x 10-6 rads.6 i
d.
Hence, the normal radiation background levels encountered by an I
aircraft at altitudes of 20,000 feet and 40,000 feet are about a factor of 3 times and 30 times, respectively, greater than
)
the radiation levels around a normally operating nuclear power I
plant. Also, the radiation field, even in the plume, of a l
normally operating reactor is estimated to be about a factor of r
1 10 times less than the dose rates considered to produce electronic equipment malfunction.
r' R_adiation Levels During Severe Reacter Accidents 3.
The radiation dose rate received by an aircraft flying through a release of fission products during or after an accident is almost completely cetermined by the concentration of gaseous fission products in the air surrounding the aircraft and by the transmission An aerial radiological survey of the area surrounding the Big Rock Nuclear P1 ant - EGG-1183-1701.

I i.
of high energy gamma rays from the site of the release. This ionization dose rate would be chiefly due to Compton scattered gamma rays rather than direct transmission, and the exact dose received would be markedly dependent upon the age of the fission products and the speed of the aircraft through the plume.
Gaseous Fission Product Dose An aircraft 1000 feet above ground may be envisioned as at the center of a sphere whose surface just touches the ground. This 03 sphere would have a volume of 1.2 x 10 m.
If the entire end-of-life core inventory of gaseous fission products is assumed to be dispersed unformly in this sphere, the dose rate to the exterior of the aircraft would be 2500 Rad / hour (0.69 rad /sec). Of this dose rate, 1700 Rad / hour (0.47 r/sec) would be due to 2.8 - hour half-life 85 Kr, and an additional 650 rad / hour (0.180 r/sec) would be due to even shorter-lived radioisotopes.
Ground Shine Dose The dose transmission through 1000 feet of air is 3 x 10-10 and 1 x 10'11 Rads / curie-second for 1 meV and 0.1 MeV gamma ray sources, respectively. The fractions of these transmissions due to Compton scattering are 75% and 97%, respectively.
0 If it is assumed that 10 curies of 1 MeV gamma ray emitters are lying u'nshielded on the ground, an. aircraft flying 1000 feet above them would receive a maximum dcse rate of 108 Rads / hour (0.03 r/sec).

m 4-Effects of Accidents The maximum hypothetical radiation dose rate (pulse) of an aircraft l
entering the radioactive spherical cloud described above is 0.69 i
)
rads /sec. This is a factor of 140,000 below that dose rate which Olesen indicates is required to cause a change in the operation of semi-conductor devices. Furthermore, if it is assumed that the aircraft flys directly through the center of the contaminated cloud at 300 moh (4 0 f t/sec) it will take 4.5 seconds to travel through the contaminated plume. During this time, the dose to the aircraft would be approximately 5
4.5 x 0.69 r/sec or 3.1 rads. This is a factor of 3.2 x 10 below the total dose required to produce slightly affected operation in electronic l
components. Aircraft flying at higher altitudes would receive a far lesser J
dose from this hypothetical accident.
The dose evaluation of aircraft flying through a postulated large release of activity was done only to scope the Texpirg contention.
Actually, even though the radiation environment is far below that which would cause a response in aircraft electronics, aircraft in the vicinity of the release of any radioactive or other potentially hazardous situation would be warned by aircraft radio of the hazard and would adjust their flight paths accordingly. A recent example was the warning of aircraft to avoid volcanic dust and debris from Mt. St.
Helens..

On the basis of the foregoing, i2 conclude that Texpirg Additional Contention 50, which basically asserts that aircraft exposed to emissions from ACNGS may suffer failure or degradation of guidance systems due to " latching" and, consequently, crash near or at the site, is unsupported in fact and that no genuine issue exists with respect to this contention.
