Subject:

Quad-cities Station Units 1 and 2 - Request for Review of Reactor Duilding Stack Effluent Limita - AEC Dkts 50-254 and 50-265

Dear Mr. O' Leary:

t i

In the past four months the releases of iodine and particulate from the reactor building ventilation stack have been above the Technical Specification limit on 16 days.

These releases had no measured offect on the iodine content of the milk from cows at the nearest pasturable land or any milk sampling location. This was determined from our weekly milk sampling test results. It is concluded that the Technical Specification release 4

rate limit for iodine and particulate effluents from the reactor building ventilation stack is unnecessarily restrictive and should be reviewed by your staff.  ;

Our ability to take prompt corrective action on the day of a release in excess of the rate specified in Section 3.8.B.3.a is very limited. If an increase in the release rate is suspected based on an increasing CAM reading or discovery of a leak, the vent system can be isolated and the Standby Gas Treatment System initiated. Frequently, however, the release is not.known to exist i

until the iodine sample cartridge is counted the next day or until the particulate sample is analyzed three days after the high release rate occurred. Even if the release could always be detected i

immediately the effactiveness of the corrective action is questionable. The relatively low flow rate of the Standby Gas System cannot " clean out" the reactor building. If the release is detected quickly enough and the vent system isolated for the remainder of the day, we might avoid exceeding the LCO on that day.

Due to the long lived nature,of the y isotopes e A g)

, Commonwealth Edison Comp y Mr. J. F. O ' Leary October 5, 1973 involved, however, it can be seen that we are only using the building as a large hold-up volume prior to eventual release.

From our experience it is apparent that it takes 3 to 4 days after an occurrence before the release rate approaches what might be considered an equilibrium. During this period any event such as a minor leak or unit scram unavoidably puts the 1 release rate over the limit again for that day.

Recent abnormal occurrences of this nature have clearly demonstrated the sensitivity of the vent stack release rate to the concentration of iodine in the reactor coolant. This is true even though the iodine levels during transients con-tinue to be a small fraction (less than 10%) of the steady state limit of Technical Specification 3.6.C.l. This had the effect of increasing the contribution to the release rate of very minor leaks. This problem is also componnded by the relatively low capacity of the Quad-cities reactor water cleanup systems. We expect that this problem will be magni-

! fled in the near future by a recent increase in the off gas activity on Unit 2 from about 5,000 uc/see to 17,000 uc/sec at full load.

It is suggested that the following basis be used in this requested review. The present reactor building ventilation stack limit was calculated based on meteorological data for the most critical 22.5 degree section and a hypothetical cow pastured at the site boundary in the critical section. This location is north of the station where the boundary is approximately 1250 feet from the reactor building ventilation stack. Actually, the nearest pasturable land is not located at this location defined by the

' intersection of the site boundary and th gritical 22.5 0 meteoro-logical section. The nearest pasturabte .ond is located approximately 5500 feet south of t?l rae ar building ventilation stack. This is the location of th, se_;.> Club Farm.

The Saddle Club Farm extends from the southern boundary of Commonwealth Edison Company property at Quad-Cities Station, south, for 1.3 miles. The farm area consists of approximately 370 square acres, on both sides of Illinois Rt. 83.

There are 410 head of Swiss Dairy Cattle, 375 of whiph produce. The remaining 35 head are either dry or in a state of pregnancy. The farm produces approximately 7,000 lb/ day with the average output per head being 29 lb/ day / cow.

. {) Commonwealth Edison Compa y

, Mr. J. F. O' Leary October 5, 1973 The cattle are fed grain three times daily, and other than this, they are allowed to roam the farm's fields. They are in the field year round, only coming into the barns for milking.

Saddle Club Farm has a processing plant which handles only the milk produced at the farm. It is pasturized and pro-cessed into butter, ice cream, cottage cheese, and the full line of dairy products. These are sold through the plant's outlet and to groceries within the immediate area on both sides of the river.

The cattle are fed an average of 15 pounds of grain / day and 30 pounds of hay / day / head.

The attached drawing shows the location of the Final Safety Analysis Report (FSAR) site boundary, all Commonwealth Edison Company owned land contingent to the Quad-cities site, the reactor building ventilation stack and the Saddla Club Farm northern boundary.

It is requested you recalculate the reactor building ventilation stack iodine particulate effluent limit, Technical Specification 3.8.B.3.a, based on the nearest pasturable laad as the north boundary of the Saddle Club Farm. It is our estimate that using this basis the effluent limit can be raised by a factor of five (5). If your review results in a recalculated Technical Specification limit based on the nearest cow at the Saddle club Farm we propose the following measures to ensure the environmental effects remain insignificant. As indicated on the attached drawing, all hypothetically pasturable land between the Quad-Cities Station and the Saddle Club Farm is owned by Commonwealth Edison Company. To verify that the Saddle Club Farm is the nearest land used for pasturing milk cows, a survey will be. conducted annually during the grazing season. To verify that there is no measurable effect of an increased Technical Specification limit, the milk sampling program at the Saddle Club Farm will be continued on a weekly basis for the first year of operation with increased effluent limits.
