Licensee Action on Previous Inspection Findings
(Closed) Infraction (50-295/80-11; 50-304-80-11): Failure to
a.
standardize the sodium hydroxide solution used in the boric
acid titration. The licensee revised Procedure ZCP-23 on
November 12, 1980, which requires this standardization to be
done only for those shifts when a boron analysis is done. The
l
inspector observed the standardization of a sodium hydroxide
solution during a boric acid titration and reviewed selected
l
1981 records for this inspection. No problems were identified.
l
b.
(Closed) Infraction (50-295/80-11; 50-304/80-1:): Failure to
conduct the required conductivity measurements in accordance
with ZCP-213. The licensee modified the procedure and check
sheet on November 26, 1980 to assure the required analyses are
performed. Review of 1981 records during this inspection
confirmed the samples were being taken.
(Closed) Deficiency (50-295/80-11; 50-304/80-11): Failure to
c.
provide documentation that the required surveillance had been
conducted in accordance with ZCP-216. The licensee has modified
record retention procedures to improve record keeping controls.
The inspector has no further questions regarding this item.

d.
(Closed) Open Item (50-295/80-11): Discrepancies between
sample numbers shown on the map in Section 4.16 of Appendix A,
Technical Specifications and those actually used in the radio-
logical environmental monitoring program (REMP) by the licensee
contractor. The contractor (Eberline) has provided in the 1980
Annual Report a listing relating the two sets of sample numbers.
The new contractor (Hazleton) will use a numbering system con-
sistent with the Technical Specifications map.
3.
General
The licensee's 1980 radiological and meteorological environmental
'
monitoring program including implementation, sampling equipment and
locations, and program results, were reviewed during this inspection.
The inspector also reviewed internal audits of these programs.
The inspector examined the radiological and nonradiological chemistry
program including quality assurance and quality control for the con-
firmatory measurements inspection program. An internal audit was also
reviewed.
Appendix A, Technical Specifications, served as primary criteria during
this inspection.
4.
Administrative and Procedural Controls
'
The inspector reviewed the administrative and procedural controls for .
implementing the REMP program.
Dr. J. Golden has prime r sponsibility
for the conduct of the REMP as well as the meteorological monitoring
program. Murray and Trettle, Inc., remains as the meteorological con-
tractor but Hazleton Environmental Sciences Corporation became the new
i
REMP contractor as of February 1,1981. Eberline Instrument Corporation
was the former contractor who performed the 1980 REMP.
No items of noncompliance or deviations were identified.
5.
Licensee Audits
Licensee QA Department Audits made in July 1980, of the REMP contractor
(Eberline) and in August 1980, of the meteorological contractor (Murray
and Trettel) were reviewed. Audit findings and observations were
followed up and the audits were not closed out until the contractors'
l
corrective actions were completed.
An audit (QA-22-80-50) conducted on Septembe- 29, 1980, of the radio-
chemical and chemical control program at the plant noted nonuniform
time intervals between successive measurements of conductivity in the
secondary system. The licensee revised Procedure 7CP-213 to require
conductivity measurements every four hours rather than twice per shift;
,
a surveillance (QAD-8-22-80-82) conducted on December 2, 1980, verified
implementation of the revised procedure.
No items of noncompliance or deviations were identified.

Quality Assurance and Quality Control of Analytical Measurements
on Reactor Wster Systems
a.
Nonradiological Analysis of Reactor Coolant
-
Selected licensee laboratory procedures for nonradiological
effluent and sampling and chemical analysis of reactor and
secondary coolant were reviewed to determine their adequacy
and completeness. Procedures updated during CY 1980 and 1981
to the date of this inspection included analyses for total
alkalinity, aluminum, hydrogen, conductivity, boron, total
suspended solids, chlorides, and sampling procedures. All
procedures had been reviewed by the lead chemist and plant
management.
The inspector also toured the licensee's nonradiological chemistry
laboratory and observed that all laboratory instruments appeared to
be functional and operable, and the chemical solutions were currently
dated. Calibrations of laboratory instruments are verified on a
monthly schedule. The inspector observed the rad-ches technicians
performing various analyses on samples collected. No technical weak-
nesses were noted.
The inspector examined selected logs, check sheets and other records
of analytical results (for the period of January 1,1981 to date)
which are reviewed daily by the lead chemist. No problems were
~
identified.

.
.
b.
Radiological Analysis of Reactor Coolant and Liquid Effluents
The inspector reviewed selected reactor coolant and radiological
effluent procedures pertaining to radiochemical separations and
analyses of radionuclides and counting room procedures. The lead
chemist and plant management reviewed and approved several
new
procedures for CY 1980 and 1981 regarding operation of new counting
instruments obtained during the past year. The licensee's daily
-
checks of energy calibration of the new gamma spectrometers were
also reviewed. A tour of the licensee's radiological chemistry
laboratory revealed no major problem areas.
Selected results of quality and functional checks of the licensee's
l
alpha-beta counter and multichannel analyzers were reviewed. All
l
checks required by the procedures were conducted and recorded. No
l
problems were identified.
c.
Training of Chemistry Laboratory Personnel
,
Programs for training new chemistry laboratory personnel were
!
discussed with the licensee. A formal training program includes
a one-week orientation; a five week system-description of plant
operation; a four month laboratory training program including
hands-on laboratory experience. Examinations were given during
the training period. The licensee's initial training program for
chemical laboratory practices appeared to be adequate.

Implementation of the REMP
,
The inspector examined the licensee's REMP for CY 1980 for compliance
with monitoring and reporting requirements in accordance with Sections
3.16 and 4.16 of the Appendix A, Technical Specifications. This in-
cluded examination of the Annual Report submitted by the licensee to
the NRC and the detailed monthly reports containing specific analytical
data. Review of these documents indicated that all samples except
sediment had been properly collected at the specified locations in
accordance with T/S Table 4.16-1.
The detailed monthly reports show
that the sediment sample was collected at the Discharge for Unit 1
(Z-23S) and at the Discharge for Unit 2 (Z-23N) rather than at the
Illinois Beach State Park (Z-25). This is an apparent violation of
Technical Specification Table 4.16.1, Item 7.
The analytical results indicated no unusual results or trends ascrib-
able to plant operation. The effects of the fallout from the weapons
testing by the Peoples' Republic of China could be seen in air-filters
collected in December 1980. The licensee.also performed an annual milch
animal census and found no milch animals within a five-mile radius of
the station. The closest dairy animals on record are located just over
five miles at 270* from the station (Z-32).
The inspector visited five air monitoring stations and found each
station was in operation and properly maintained, and the TLDs properly
placed. Records showed that the stations had been calibrated and
maintained in accordance with Technical Specification (Table 4.16-1)
requirements. No problems were identified.
The inspector reviewed the quality control program of the licensee's
environmental contractor including the results from participation in
'
the U.S. Environmental Protection Agency's cross check program. No
technical weaknesses were identified.
,
One item of noncompliance was identified.
l
7.
Meteorolonical Monitoring Program
The inspector reviewed the meteorological monitoring reports for
CY<1980 prepared by the licensee's meteorological contractor. The
overall recovery rate of meteoro1 Logical data was 99.5% which meets
the guidance of Regulatory Nide 1.23.
The inspector noted the
contractor had maintained and calibrated the meteorological instru-
mentation on a bi-monthly schedule. The licensee is installing new
readout egipment which will use computers for dose calculations in
the technical support center for emergency planning situations. At
the present time the meteorological data are recorded through the
microtel system at the licensee's corporate center.
No items of noncompliance or deviations were identifed.

d.
Laboratory and Counting Room Operations
The inspector examined the licensee's quality control practices
~
for nonradiological and radiological measurements, including
performance checks and calibrations of chemical and radiation
counting equipment. The inspector noted that plant management
la promptly notified when unusual results or chemical specifica-
tions are exceeded. However, spikes or blind samples are seldom
given to technicians to check their laboratory results. The
licensee representatives agreed to consider adoption of such
quality control practices.
The inspector observed that laboratory operations had considerably
improved since the previous inspection owing to new equipment,
revised procedures, new personnel, and better working conditions.
No items of noncompliance or deviations were identified.
9.
Exit Interviews
The inspector met with licensee representatives (denoted in Paragraph 1)
on May 12, 1981, at tne licensee's corporate headquarters and on May 20,
1981, at the plant site at the conclusion of this inspection. The in-
spector summarized the purpose, scope and findings of this insp,ection.
