Inspection Summary:
Ins ection on Se tember 6-7 1978 (Re ort No. 50-315/78-26'0-316/78-25 Areas Ins ected:
Special confirmatory measurements inspection, including a discussion of the licensee's results for the last sample analyses and a special collection of split liquid and gaseous waste samples.
The inspection involved seven inspector-hours on site by one NRC inspector.
Results:
In the area inspected, no items of noncompliance or deviations were identifie DETAILS 1.
Persons Contacted
- B. Svenson, Assistant Plant Manager E. Smarella, Technical Superintendent J. Wojcik, Chemistry Supervisor
- Denotes those present at exit interview.
2.
Confirmator Measurements Pro ram The inspector collected special samples of the licensee's gaseous
~aste and liquid waste.
Results of the previous split sample analyses were discussed with the licensee.
No explanations for the disagreements with the results from the NRC Reference Laboratory (RESL) were apparent.
The licensee stated that they have recounted NBS standards, and calibrations appear to be correct.
However, they will check the curve to determine if it is skewed.
The licensee is presently discussing these problems with their analytical contractor.
The licensee stated that the problem may a1,so be a geometry problem, or a problem with laboratory technique.
A spiked liquid sample in the licensee's geometry was ordered from the NRC Reference Laboratory.
Sample results and the criteria for comparison are enclosed as Table
and Attachment 1, respectively.
3.
Exit Interview The inspector met with the licensee representative denoted in Paragraph 1 at the conclusion of the inspection.
The representative agreed to:
a.
Count the spiked sample supplied by RESL; b.
Check the efficiency curve to determine if one parabola is skewed; and c.
Consider employing the services of a consultant to work with plant personnel to identify and eliminate the problems in the laboratory.

CRIT)'.RIA FOR CO':)PART)lG ANALYTICALHEAR)IRE))'.NTS This attachment provides cri.teria for comparing results of capability tests and verification measurements.
The criteria are based on an empirical relationshi.p which combines prior e>;perience and the accuracy needs of this program.
In these criteria, the judgment limits are variable in relation to the comparison of the NRC Reference Laboratory's value to its associated one sigma uncertainty.
As that ratio, referred to in this program as
."Resolution",
increases, the acceptabili.ty of a licen ee's measurement should be more selective.
Conversely, poorer agreement should be con-sidered acceptable as the resolution decreases.
The values in the ratio
. criteria may be rounded to fewer significant figures to maintain statistical. consistency with the number of significant figures reported by the NRC Reference Laboratory, unless such rounding will result in a narrowed category of acceptance.
The acceptance category reported vill be th'e narrowest into which the ratio fits for the resolution being used.

"A" criteria are applied to the following analyses:
Gamma spectrometry, vhere principal gamma energy used for identifi-cation is greater than 250 keV.
Tritium analyses of liquid samples.
"3" criteria are applied to the following analyses:
V Gamma spectrometry, where principal gamma energy used for identifi-cation is less than 250 keV.
Sr-89 and Sr-90 determinations.
Gross beta, where samples are counted on the same date using the same reference nuclide.
