INSTRUMENTATION D

RADIOACTIVE LIQUID EFFLUENT MONITORING INSTRUMENTATION LIMITING CONDITION FOR OPERATION 3.3.3.10 The radioactive liquid effluent monitoring instrumentation channels shown in Table 3.3-12:shall be OPERABLE with their alarm / trip setpoints set to ensure that the limits of Specification 3.11.1.1 are not exceeded.

The alarm /

trip setpoints of these channels shall be determined and adjusted in accordance with the metho'dology and parameters in the OFFSITE DOSE CALCULATION MANUAL (003).

APPLICABILITY: At all times.

ACTION:

With radioactive liquid effluent monitoring instrumentation channel a.

alarm / trip setpoint less. conservative than required by the above Specification,_immediately suspend the release of radioactive liquid effluents monitored by the affected channel, or declare the channel inoperable.

b.

With less than the minimum number of radioactive liquid effluent monitoring instrumentation channels OPERABLE, take the ACTION shown in Table 3.3-12. Restore the inoperable instrumentation to OPERABLE

[

status within the time specified in the ACTION or, explain in the next Semiannual Radioactive Effluent Release Report, pursuant to Specification 6.9.1.8, why this inoperability was not corrected within the time specified.

The ' provisions of Specifications 3.0.3 and 3.0.4 are not applicable.

c.

SURVEILLANCE REQUIREMENTS 4.3.3.10 Each radioactive liquid effluent monitoring instrumentation channel

.shall be demonstrated OPERABLE by performance of the CHANNEL CHECK, SOURCE CHECX, CHANNEL CALIBRATION and CHANNEL FUNCTIONAL TEST operations at the frequencies shown in Table 4.3-8.

"The LLD is defined, for purposes of these specifications, as the smallest t

concentration of radioactive material in a sample that will yield a net count,

~ bove system background, that will be detected.with 95% probability with only a

5% probability of falsely concluding that a blank observation represents a "real" signal.

For a particular measurement system, which may include radiochemical separation:

exp (-Aat)

Where:'

LLD is the "a priori" lower lir.it of detection as defined above, as microcuries per unit mass or volume, s is the standard deviation of the background counting rate or of the h

ccunting rate of a blank sample as appropriate, as counts per minute, E is the counting efficiency, as counts per disintegration, V is the sample size in units of mass or volume, 2.22 x 10e -is the number of disintegrations per minute per microcurie, Y is the fractional radiochemical yield, when applicable, A is the radioactive decay constant for the particular radionuclide, and at for plant effluents is the elapsed time between the midpoint of sample collection and the time of counting.

Typical values of E, V, Y, and at should be used in the calculation.

It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement.

.bA batch release is the discharge of liquid wastes of a discrete volume.

Prior to sampling for analyses, each batch shall be isolated, and then thoroughly mixed by a method described in the ODCM to assure representative

-sampling.

Zn-65,_Mo-99, Cs-134, Cs-137, Ce-141, and Ce-144. This list does not mean

-that only these nuclides are to be considered. Other gamma peaks that are identifiable, together with those of-the above nuclides, shall also be analyzed and reported in the Semiannual Radioactive Effluent Release Report pursuant to Specification 6.9.L 8.

dA. composite sample is one in which the quantity of liquid sampled is proportional to'the quantity of liquid waste discharged and in which the method of s,ampling employed results in a specimen that is representative of the liquids released.

'A continuous release is.the discharge of liquid wastes qf a nondiscrete volume,' e.g.. from a volume of a system that has an input flow during the continuous release.-

' IPrior to analyses, all samples taken for the composite shall be thoroughly mixed in order for the composite sample to be representative of the effluent release.

IIf the contents of the filter flush tank.or the regenerative waste tank contain detectable radioactivity, no discharges from these_ tanks shall be made to the UNRESTRICTED AREA and the contents of these tanks shall be directed to n

the liquid radwaste treatment system.
