-
!a; e(Clo' sed) Open Item (50-255/84021-01):
Complet!e chemistry procedures required by chemistry program manual.

'
procedures for~the laboratory. quality control program, chemistry group.
-
measu' ring and test equipment-and counting room equipment were reviewed
.

procedures, although available, were not examined during this. inspe:: tion.
- b'
(Clo' sed) Open Item (50-255/84021-02):
Investigate the-source of
.
~ levated gross beta activity in the Van Buren State Park well water
e v
relative to-the gross beta activity of the onsite well water.
The licensee analyzed samples from these wells'specifically for K-40, and Ra 226 and Ra 228 to see if thav contributed to'the' variable beta-activity. The '.K-40 results, ar the Ra results since. January 1985,
,
'
were-inconclusive and statisticilly. insignificant.
Independent samples (
analyzed by the NRC.show no significant activity in either well (See Table 2).
L c.
(Closed) Open Item (50-255/84021-03):. Tag each environmental air sampler-with dates of. calibration.
A member of.the Radiation Material'
!
- Contro1' group who was interviewed stated that he reviews the calibra-tion' tickets, transfered calibration dates to the' stickers and affixed-
!
them to the air. samplers.
As the calibration tickets, not.the
-
stickers, are source documents for verification of. calibration, the actual placement of.the stickers'was not verified during this inspection.-
'
'd.
(Closed) Open-Item-(50-255/84021-04): Analyze liquid for beta emitters E
.
and report.results.to Region III.
Comparative results_are presented O
in. Table 1 and comparison criteria are outlined in Attachment 1; The
,
. test' criterion.for Sr-90 was relaxed to account for errors-introduced

F
,in radiochemistry required to prepare the sample for counting.

(Closed) Open Item (50-255/84021-05):

inferred efficiency for Xe-133.
Current calibration data for gas-
-were examined by the inspector and were found to contain measured efficiency points.
' 3.
-QA/QC'of Analytical Measurements
.
The inspector reviewed daily instrument performance tests.for counting room equipment and examined equipment and chemicals in the radiochemistry laboratory..
The licensee's' program for quality control in the counting room __is a six month calibration interval and daily performance tests.
The gamma
, spectroscopy system has limits for both energy and quantification of a Ho-166m source.
Twelve energies + 0.80 key and accurate quantification attheseenergiesdeterminedbyf3standarddeviationsof.theaverageof ten previous counts must all be satisfied for an acceptable test.
One
~
recount is allowed before the equipment'is' listed a's out of service (00S)
-and a sign, to this effect, is' physically placed on the terminal.
Other equipment, proportional. counters and a well counter, have limits of 5% of the activity of a source'whose value was determined during the previous calibration. -A-liquid scintillation counter had a daily _ limit of 3%_for an external check source and a monthly limit of 5% for a C-14 standard.
- The review indicated that for selected periods examined, tests were run on a prescribed frequency'and for the few times a test was out of specification the result was so noted. Although not procedurally-
. required, chemistry supervision does document the review of performance test results.
Minor discrepancies.in the laboratory quality control procedure.were-discussed with a licensee representative.
The discrepancies were ackn' wledged and changes currently under consideration to strengthen the o
laboratory quality control. program, primarily in documentation, were'
-discussed.with the inspector.
In addition, the importance of-trend plotting, and of communicating-to an analyst the corrective actions taken to return to service an instrument found_beyond test limits were discussed. No problems were observed in thel radiochemistry laboratory.
- The licensee does not participate in any radiological crosscheck program.
- Nonradiological crosscheck samples were received from the EPA and Nuclear Water Technology for metal, dissolved oxygen, conductivity, suspended solids'etc. ~QA Audit _No. QT-85-18_(Section 4) addressed these samples and-indicated results to be totally. satisfactory.
'
No violations or deviations were identified in'this area.
4.
Audits The inspector' reviewed Audit Report No. QT-85-18, Palisades Plant Chemistry,
-
conducted September 9-13, 1985. The purpose of the audit was to verify that
applicable elements.of the' Quality Assurance Program had been developed, documented and effectively implemented for Plant Chemistry at Palisades.
'
~One finding where the requirements described by the newly issued Chemistry Program Manual, Plant Administrative Procedures and Chemistry Department

Procedures had not been implemented, one observation relating to discrepancies in referencing of. procedures and one observation of_an inconsistency between a Chemistry and Plant Administrative Procedure-were noted.
A follow-up audit was recommended in early 1986, and will be reviewed during the next inspection.
No violations or deviations were identified in this area.
S.
' Confirmatory Measurements Sample Split A sample of a Clean Waste. Receiver Tank T-64B was split with the licensee.
The licensee agreed to analyze his portion for gamma emitters, gross beta, H-3, Sr-89 and Sr-90, and report the results to Region III (0 pen Item 50-255/85025-01).
No violations or deviations were identified in this area.
6.
Exit Interview
.The inspector reviewed the scope and findings of the inspection with licensee representatives (Section 1) at the conclusion of the site portion of the inspection on August 18, 1985.
The QA/QC program was specifically discussed and comments made by the inspector were acknowledged.
During the interview the inspector discussed the likely informational content of the inspection report.
Licensee representatives did not consider the proposed content as proprietary.
