The setpoints are found by solving Equations 2.6 and 2.7 for each class of release. , l For this evaluation the radioactivity mixture in the exhaust air is assumed to have the compositiod'of gases listed in' Table 3-3 from " Technical Derivation of BWR 1971 Design Basis Radioactive Material Source Terms," NEDO-10871, March 1973, General Electric Company.

LA SALLE REVISION 11 NOVEMBER 1985 k- 8.2.6 Administrative and Procedural Controls for Radwaste Discharges Administrative and procedural controls have been designed to ensure proper control of radioactive liquid radwaste discharge in order to preclude a release in excess of 10 CFR 20 limits.
The discharge rate for each batch is calculated by a technician and then independently verified by operating staff personnel.
All liquid radwaste discharges will be from one of two river discharge tanks, lWF05T or 2WF05T.
The keylock hand switch, OHS-WF048, used for selecting high or low discharge flow is kept locked except when discharging.
The key for this switch and the locked valves is under the administrative control of the Shift Engineer.
A documented valve checklist is prepared for each batch discharge.
(~}/
\- The proper valve lineup is made by the Operator and echecked by the Radwaste Foreman. The actual discharge is authorized by the Shift Engineer.
The system is equipped with a radiation trip point which alarms and initiates automatic valve closure on the radwaste discharge line to prevent the violation of 10 CFR 20 limits.
8.2.7 Determination of Initial Dilution Stream Flow Rates For those release paths which have installed flow monitoring instrumentation, that instrumentation will be used to determine the flow rate of the initial dilution stream. This instrumenta-
! tion will be operated and maintained as prescribed by the Tech-nical Specifications. For those release paths which do not have installed flow monitoring instrumentation, flow rates will be determined by use of appropriate engineering data such as
\ pump curves, differential pressures, or valve position indication.

8.4 ENVIRONMENTAL RADIOLOGICAL MONITORING The environmental radiological monitoring program to be performed !
in the environs around La Salle County Station is given in Table 8.4-1.
Figure 8.4-1 shows the 14 fixed air sampling sites and TLD locations; also shown are the " outer ring" (approximately 5 miles distant)
TLD locations. Figure 8.4-2 shows the " inner ring" TLD locations.
Figure 8.4-3 shows all other sampling locations. Most of the TLD's l are code numbered as follows: XYY-N, where:
X= 1 means inner ring, X-2 =cens outer ring, and YY-N is an idenesfication code.
The reporting levels for radioactivity concentrations in environmental samples are given in Table 8.4-2.
The lower limits of detection for this program are given in l Table 8.4-3.

- a. The LLD is the smallest concentration of radioactive material in a sample that will be detected with 954 probability with 54 probability of falsely concluding that a blank observation represents a "real" signal.
For a particular measurement system (which may include radiochemical separation) :
4.66 s b LLD =
E . V . 2.22. Y r exp (-Aa t) where:
LLD is the "a priori" lower limit of detection as defined above (as picocurie per unit mass or volume),
ss is the standard deviation of the background counting rXte or of the counting rate of a blank sample as appropriate (as counts per minute),
E is the counting efficiency (as counts per transformation) ,
r
( ,)\ V is the s nple size (in units of mass or volume),
2.22 is the number of transformations per minute per picocurie, Y is the fractional radiochemical yield (when applicable),
A is the radioactive decay constant for the particular I radionuclide, and l At is the elapsed time between sample collection (or i end of the sample collection period) and time of counting I (for environmental samples, not plant effluents).
The value of s s used in the calculation of the LLD for a detection system shall be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background sha11' include the typical contributions of other radionuclides normally present in the samples (e.g.,
potassium-40 in milk samples). Typical values of E, V, Y, and at shall be used in the calculations.
[k/) b. Other peaks which are measurable and identifiable, together with the radionuclides in Table 8.4-3 shall be identified and reported.
