Dear Mr. O' Leary:

MONTICELLO NUCLEAR GENERATING PIANT Docket No. 50-263 License No. DPR-22 l

Revised Pages for Semi-Annual Operating Report #4 July - December, 1972

(

. Enclosed are 40 sets of 29 replacement pages for the Monticello Nuclear Generating Plant Semi-Annual Operating Report that was sent to Mr.

Giambusso on February 28, 1973.

The page for Section V of the report corrects erroneous entries for the volume of solid waste shipped. The replacement pages for Section VI-A and VI-B on environmental monitoring reflect the incorporation of infor-mation on 90Sr analyses and inherent TLD background data which was not yet available at the time the report was submitted. The compensation for TLD backgrounds also affected some of the statistical analyses pre-viously submitted. The data that has been revised is noted by marginal sidelines or encircling specific entries.

Yours very truly, WO.f a

All TLD values in this report, except for the value in Table 1, represent gn=ma dosage after the subtraction of individual inherent TLD backgrounds and are therefore not comparable to TLD data in previous reports. However, the conclusions which were based on these data are valid. Where possible, data from the previous report period have been presented since the inherent TLD backgrounds were not avail-able for the previous report.

The average value in Table 1 was calcu-lated without TLD background subtraction and should not be used for statistical comparison.

The first expecure period for the statistical analyses was from

{

5/10/72 to 5/30/72. The May and June data vere included since it was not available for the previous report, and since this was the first l

l exposure period for which valid data were available from the expanded k

TLD network. Data from 12/28/71 to 4/18/72 were analyzed separately because of the limited number of readings.

Table 7a is a tabulation of location coordinates for all TLD locations with respect to the plant stack.

In this report the term "on-site" location applies to locations 13 through 27, 4 and 50. The term "off-site" location applies to all i

other locations with the exception of the four Monticello area locations, 51 through 54.

The average exposure in pr/hr of all off-site, on-site, and 1

i Monticello area locations from 5/10/72 to 1/3/73 was 7.68, 8.63 and 7.86, l

respectively. The probability that the on-site values belong to the same population as the off-site values is less than 0.01.

The difference between the Monticello and off-site averages is not statistically signif-icant. From 12/28/71 to 4/18/72 the average exposure in pr/hr for locations 13-18 and 4 was 7.95, and for locations 1-3 and 5-8 vas 7.22.

The net Revised 5-15-73 VI A-2

/

j exposure increase for all on-site locations with respect to all off-site locations of 0.95 pr/hr results in an accumulated exposure for the period from 5/10/72 through 1/3/73 of 5.43 mr.

The average plant release rate from 5/10/72 to 1/3/73 was 30,450 pCi/sec. The maximum net exposure at 4

i j

an on-site location from 5/10/72 to 1/3/73 was 14.73 mr at location 26 vhich is lower than calculated in the FSAR. Background at the off-site

]

locations was 44 mr for the same period.

A tabulation of the net increase of each individual location with respect to the off-site locations from 5/10/72 through 1/3/73 is presented 1

in Table 7d. The individual off-site locations were not excluded from the total set of all off-site locations for the individual off-site comparisons.

Table 7e lists the net increase of selected on-site locations with respect to all off-site locations for each exposure period. These values l

l include two batch data which have exposure times which are slightly dif-(

ferent than those shown. The locations were selected on the basis of the 1

significance of their net individual readings. The average stack release i

rate is also shown.

Environmental Gamma Bcposure (Film Badres) Dtposure periods were four weeks. During the reporting period, nine film badges in two different exposure periods showed twelve readings above the minimum "M" (less than 10 mr). Upon examination of the stations, it was apparent the

]

badges were being placed inside the air pump shelter which retains i

heat from the air pump. On September 25, 1972, these badges were moved to points outside and away from the shelter,'and the reports 1

Topsoil is taken from three fields growing crops and being irrigated with Mississippi River water taken downstream from the plant discharge. Top-I soil is also taken from three fields in a downwind direction of the plant. These fields are not irrigated and usually grow grasses or I

veeds. The results are shown on Table 18 and averages are similar to s

preoperational and first year operational data.

(See Su mary Table 1)

Well Water is taken from three deep wells and four shallow wells in the plant area.

The results are shown on Table 11 and averages are similar to preoperational and first year operational data.

(See i

Su mnry Table 1) i Fish samples were taken from the Mississippi River at upstream and downstream locations on a quarterly basis when available. These results l

(

are shown in Table 15 and averages are similar to the preoperational and first year operational data.

(See Sumary Table 1)

Parameters in addition to those presented above are Airborne Radiciodine (Table 4), Water taken from five lakes (Table 10), Lake Bottom Sediment (Table 12), Lake and River Aquatic Vegetation (Table 13), Lake and River Attached Algae (Table 14), Lake and River Aountic Insects (Table 16), and Vegetation from several fields in the downwind area of the plant (Table 17).

The results shown in these tables are similar to preoperational and first year operation data.

Conclusion e

With the exception of the TLD data, none of the parameters analyzed showed any increase in levels of radioactivity during the period July 1, 1972 through December 31, 1972. At 1.8 miles and 1270, the TLD network detected an extrapolated annual exposure of 8.23 mr.

This is 1.67. of applicable 10 CFR 20 limits. The highest P value in Table 7e corresponds to the lowest average plant release rate. This suggests the elevated TLD values are attributable to plant operation.
