Dear Mr. Skovholt:

As required under the interim conditions for operation as directed in your letter of June 23, 1972, the Reporting Requirements for the period of August 26, 1972 through September 25, 1972 are herewith submitted.

7. 1 During this period . 0044 curies of radioactive material (excluding tritium and gasses) were discharged with liquid

'astes. The total release for the quarter was .0156 curies which is . 625% of the quarterly limit of 2.5 curies.

7.2 The average release rate for noble gasses in the gaseous waste this month was .24 millicuries per second. The limit value is

2. 4 millicuries per second.

7.3 The following table shows the maximum, minimum, and average activity values for primary, secondary, and liquid waste samples.

Primary coolant and secondary coolant degassed beta-gamma radioactivity;were measured daily. Two power changes greater than 10% occurred and no signifjcant increases in activity were noted. A radiochemical analysis was made three times per week on the primary coolant.
