Licensee Action on Previous Inspection Findings (Closed) Noncompliance (50-313/76-16):
Failure to provide written procedures for calibration and maintenance of temperature elements used in monitoring themal effluents and lack of written procedures i
stating what actions are to be taken when temal limits are approached or exceeded.
The inspector verified that the required procedures have been written and approved.
This item is closed.
(Closed) Noncompliance (50-313/76-14):
Failure to conduct the semiannual milk animal survey and report results in the Operating Report. The inspector verified that this survey has been conducted
.
and reported as required. This item is closed.
}
(Closed) Unresolved item (50-313/76-14-1):
This item involved failure to meet the required monthly ichthyoplankton entrainment
'
sampling schedule due to plant shutdown and equipment failure during 1976. The inspector found that this sampling program had been implemented in accordance with requirements in 1977.
This item is considered resolved. -

-3-(Closed) Unresolved item (50-313/76-14-2):
This item involved the issue of whether or not IE is required to inspect and enforce i
National Pollutant Discharge Elimination System (NPDES) permit limits referenced by the Appendix B Technical Specification (ETS).
The inspector has determined that the current IE policy is to limit inspection and enforcement activities only to insure compliance with the reporting requirements specified in the ETS. This item is considered resolved.
(Closed) Unresolved item (50-313/75-13-1): This item involved the lack of written procedures for quality control (QC) activities of the plant chemistry laboratory. The inspector noted that the plant chemistry laboratory ETS responsibility are currently limited to available chlorine residual in the circulating water and sanitary waste systems. This analysis is performed with the orthotolidine-colorimetric method using permanent liquid standards for comparison each use.
In view of the scope and method of analysis, no addition QC written procedures are felt to be necessary. This item is con-sidered closed.
~
(Closed) Unresolved item (50-313/75-13-2): This item involved the
'
O~
lack of fomal documentation of the assignment of responsibility and authority for implementation of the offsite environmental pro-grams. The inspector _ noted that AP&L has established such responsi-i bility and duties through Control Laboratory Procedure No. AC-03.
This item is considered resolved.
3.
Licensee's Internal Audits The inspector reviewed reports of audits of the Central Laboratory operations and inspections of ANO-Unit 1 environmental programs i
which had been perfomed since August 1977.
It was noted that three surveillance audits of the Central Laboratory operation had been perfomed and identified discrepancies were followed-up satis-factorily. Two QC inspections of environmental requirements were
'
noted to have been performed at ANO. No discrepancies were identified.
!
No items of noncompliance or deviations were identified.

J No significant changes in this area were noted except that D. A.
Rueter had been appointed Director of Technical and Environmental Services, and has been assigned direct supervisory responsibility for the offsite radiological and nonradiological environmental surveillance programs. The inspector noted that the assignment of responsibility and duties for these surveillance programs is documented in AP&L Procedure No. AC-03. The inspector had no i
additional questions in this area after his review.
5.
Quality Control of A.nalytical Measurements The inspector discussed the Central Laboratory Quality Assurance /
Quality Control (QC) procedures with licensee representatives and reviewed records showing QC activities since the previous environ-mental protection inspection.
It was noted that QC samples provided by the Environmental Protection Agency have been analyzed and good agreement obtained.
It was also noted that control charts and j
calibrations are still being maintained in accordance with Central Laboratory procedures. The inspector had no additional questions
.
in this area at this time.

Technical Specification Requirements
,
a.
Radiological
,
,
The environmental radiological surveillance requirements are contained in Section 4.2 of the Appendix B Technical Specifi-cations.
Environmental media are collected by the ANO chemistry
,
laboratory staff except for milk samples which are collected by
-
the Arkansas State Department of Health, and aquatic biota and bottom sediment collected by the University of Arkansas at i
'
Little Rock. All enviornmental radioactivity analyses are performed in the AP&L Central Laboratory at Little Rock. The inspector reviewed ANO-Unit 1 and Central Laboratory procedures for conduct of the program, and reviewed selected portions of the Semi-Annual Environmental Monitoring Reports for the second
.
'
i half of 1976 and the first half of 1977.
No items of noncompliance or deviations were identified.

and ecological studies requirements are contained in Sections 4.1 and 6.0.
The inspector examined each of these areas as follows:
'
- .
(1) Thernal Effluent The inspector reviewed procedures and records relating
,
to monitoring the. thermal effluent.
It was noted that
'
'
Procedure No. 1304.16, " Circulating Water Temperature Instrument Calibration," has been established to cover
instrument calibration and maintenance, and Procedure No.1203.08, " Exceeding Thermal Limits on Condenser Discharge Water," has been established to describe actions when thermal limits are approached or exceeded.
The inspector reviewed about 50% of the 1977 BOP computer print-outs showing monitoring of the thermal effluent.
It was noted that the maximum temperature of 1050F was-
apparently exceeded several times in July 1977.
The inspector-determined that either this limit was not ex-ceeded for more than two consecutive hours or the temper-ture was measured in the discharge canal and found to be e
i less than the limit.
It was also determined that an j
investigation was conducted and it was found that this
,
condition resulted from lowering of the water level at the dam with a resultant influx of warm surface water at the intake of ANO-Unit 1.
The inspector had no additional questions in this area at this time.
(2) Chemical Effluent The inspector reviewed the licensee's chemical surveillance
,
data for the period October 1976 'through 0ctober 1977.
The
,
inspector noted that available chlorine residual values for the circulating water system and annual inventory of i
chemical usage were in accordance with ETS requirements.
- It was also noted that the sewage treatment system was in l
the start-up stage and monitoring of the available chlorine i
residual -is planned for once per week. The inspector
!
questioned the QC program for the chlorine determination
j but accepted the licensee's position that the colorimetric analysis requires no additional QC other than the comparison with permanent standards each time the analysis is performed.

Impingement and Entrainment Monitoring The inspector reviewed records showing the fish impinge-
'
ment and ichthyoplankton entrainment monitoring programs.
Both of these programs appeared to meet the ETS require-ments. The inspector had no additional questions in this area at this time.
-
^- -

(4) Offsite Nonradiological Studies and Surveillance The inspector discussed the status of the offsite non-radiological studies and surveillance with Central Lab-oratory personnel, and reviewed reports submitted in the Semi-Annual Reports for the second half of 1976 and first half of 1977.
It was noted that reports and data from these contracted studies are reviewed for scientific
.
content and ETS compliance in accordance with Procedure No. QC-09.
It was algo noted that the Texas Instruments audit reconnendationsl/ were followed-up in letters to the special studies contractors establishing the scopes of work, review procedures, procedures for making controlled changes, and QC and calibration procedures. The inspector had no additional questions in this area at this time.
ON No items of noncompliance or deviations were' identified.
7.
Tour of Environmental Sampling Stations The inspector visted environmental radioactivity sampling stations Nos. 1 through 5 on December 15, 1977.
No discrepancies were noted.
8.
Reportable Occurrences
The inspector reviewed the nonroutine reports submitted to NRC since the previous environmental protection inspection.
The following reports were noted.
,
a.
Nonradiological
77-1, June 15,1977 - thermal effluent AT 15.050F when corrected
-
for last calibration factor.
Flow stopped and AT i
~
reduced to 14.30F.
.
77-2, June 16, 1977 - Above report cancelled, calibration factor lower than used.

Radiological 77-1, October 14, 1977 - milk samples collected October 3 and 4,1977, exceeded ETS 5.6.2.(b)(1) for 131 I and are reportable under ETS 5.6.2.(b)(1).
The activity in
'
these samples was attributed to radioactive fallout from the PRC nuclear test of September 17, 1977.
77-2, November 1,1977 - Milk and vegetation samples taken during October 1977, exceed ETS limits for 131, 90 r I
S
'
and 89Sr. The activity in these samples was attributed to the PRC nuclear test of September 17, 1977.
i The inspector noted that the results reported were consistent with observations by other environmental surveillance programs
'
and concurred that the levels were not related to ANO-Unit No. 1 operation.
The inspector had no additional questions in this area at this time.
9.
Exit Interview
'
The inspector met with AP&L representatives denoted in paragraph 1 O
on December 15, 1977, at the ANO site and on December 16, 1977, at the General Offices in Little Rock, Arkansas, following the inspection. The purpose and scope of the inspection were outlined and the findings were discussed.
