The total release for the past three months was.059 curies which is 2.36%

of the quarterly limit of 2.5 curies.

7.2 The average release rate for noble gasses in the gaseous waste this month was.068 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 radio-activity were measured daily, while the reactor was critical, and radiochemical analysis was made three times per week.
