PREREOQISITES 1.
Efficiency calibration constants for the chosen sample geometry and detector to be used must be available.
2.
The person performing the analysis should have an understanding of the operation of the equipment and associated procedures.
3.
The samples..should have been prepared for counting in accordance with References 2, 4,
5 or 6.
4.
Appropriate sample information has been supplied on the sample information sheet or sample Ic. bel.
l D.
EEECAUTIONS 1.
FOLLOW radiation protection guidelines in accordance with Reference 3.
E.
LIMITATIONS AND ACTIONS 1.
11 the sample exceeds the 20% deadtime check, and the sample is on the highest shelf and cannot be diluted, NOTIFY Chemistry Supervision.

For compliance to Tech Spec 4 11.2.1.2, gaseous effluent analysis MUST be completed within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of the time the samples were taken.
4.
RETER to Reference 1 for radioactivity limits.
5.
This procedure is applicable to both normal or post-accident analysis.
6.
Existing Sample Information Sheets can be used to obtain the I
information required by this procedure.
7.
A remote VT320 is attached to the system to allow the ND66-XP to l
remain in the MCA mode.
Other equipment configurations may be authorized by Chemistry Supervision.
