Quality Assurance Program for e' .Jent and environmental monitoring,
using the guidance in Regulatory Juide 1.21. Revision 1, June 1974,
!
and Regulatory Guide 4.1, Revision 1, April 1975.
The inspector selectively reviewed Health Physics Procedures in the
following areas:
HP-REMM.
The ten procedures in this group constitute the REM Manual
which defines the Radiological Environmental Monitoring Progran
HP-00CM.
These fourteen procedures plus Appendices constitute the
00CM.
Health Physics Procedures covering calibration, opera *. ion , and
performance checks of count room equipment; liquid and gaseous
radwaste sampling and analysis; radwaste release, release records,
and dose assessment; effluent monitor setpoints; and accidental,
unplanned or uncontrolled radwaste release.
The inspector also
selectively reviewed Instrument Calibration Procedures specified for
effluent monitor calibration and functional checks and meteorological
instrumentation calibration and functional checks.
The inspector determined through selective reviews of the procedures and
discussions with licensee representatives that the requirements of the
Technical Specifications appeared to have been met.
Licensee
representatives stated the corporate Health Physics was rewriting
performance and calibration procedures to ensure conformity with the
Radiation Protection Plan.
-
No violations or deviations were identified.
6.
Radioactive Effluent Monitoring Instrumentation (84723, 84724)
Technical Specifications 3.3.3.10 (Unit 1) and 3.3.3.9 (Unit 2) require
radioactive liquid and gaseous effluent monitoring instrumentation
channels to be operable with their alarm / trip setpoints set in accordance
with the ODCM.
Technical Specification Tables 4.3-13 (Unit 1) and 4.3-12
(Unit 2) establish frequencies for channel checks source checks, channel
calibrations, and channel functional tests for radioactive liquid effluent
monitoring instrumentation, and Tables 3.3-14 (Unit 1) and 3.3-13 (Unit 2)
established frequencies for channel checks, source checks, channel
i
calibrations, and channel functional tests for radioactive gaseous
effluent monitoring instrumentation.
The inspector selectively reviewed calibration and channel check records
for liquid and gaseous effluent radiation monitoring systems.
Calibratiens and checks appeared to have been done at intervals required
by Technical Specifications and procedures.
The inspector noted several

liquid and gaseous effluent monitors during a tour of the plant.
The
monitoring systems appeared to be properly installed and maintained.
'
No violations or deviations were identified.
7.
CountRoomInstrumentation(84723,84734)
The inspector toured the count room, discussed the equipment and
procedures with licensee representative and examined calibration and
functional check records for the instruments.
The counting room is equipped with three HPGe Ortec detector systems with
Nuclear Data MCA 6700 analysis and display, one Beckman LS-100C Liquid
Scintillation system, and two PC-5 HMC Proportional counters.
Licensee
representatives stated that an additional gamma spectroscopy system and a
PC-4 proportional counter were maintained in the Plant Training Center.
,
i
The inspector reviewed the records for the count room instruments and
verified that calibrations and functional checks appeared to have been
.
done at frequencies specified in appropriate procedures.

Radioactive Liquid Waste (84723)
l
'
Technical
Specification 3/4.11.1 establishes upper limits for
4
,
concentrations of radioactive material in liquid effluents.
The inspector
selectively reviewed release records for the period June 1987 to
r
April 1988; which included release reports, abnormal release reports, dose
assessment records, and dose projections.
All releases reviewed were
'
within Technical Specification limits.
No violations or deviations were identified.
9.
RadioactiveGaseousWaste(84724)
'
Technical
Specification 3/4.11.2 establishes upper limits for
concentration of radioactive material in gaseous effluents. The inspector
'
selectively reviewed release records for the period from June 1987; to
April 1988; which included release reports, abnormal release reports, dose
assessment records, and dose projections.
All releases reviewed were
within Technical Specification limits.
!
No violations or deviations were identified.
10. Radiological Environmental Monituring (80721)

Exposure Pathway and/or Sample;
Number of Samples and Sample Locations;
Sampling and Collection Frequency; and
Type and frequency of Analysis
The licensee implements the Technical Specification requirements
through the REM Manual and the ODCM.
The inspector and a licensee representative visited five
environmental sampling sites where collocated NRC and licensee
thermoluminescent dosimeters (TLDs) were located.
Licensee air
samplers were located at three of the stations and State TLDs were
collocated at two of the stations.
Licensee representatives stated that all environmental sample's were
shipped to a contractor for analysis.
The inspector selectively
reviewed environmental analysis reports for the period from July 1986
through January 12, 1988.
The inspector noted that the contractor
listed those samples not taken due to nonavailability. The inspector
determined that sampling and analyses appeared to have been done at
the required frequencies, and that no results exceeded the Action
Levels specified in Technical Specification Table 4.12-2.
b.
Technical Specifications 3/4.12.2 requires a land use census to be
conducted during the growing season at least once per 12 months. The
inspector reviewed the results of the census conducted in July 28-30,
1987.
The census provided the data specified in the Technical
Specification.
c.
Technical Specific
lon 3/4.3.3.4 requires that the meteorological
monitoring instrumentation channels shown in Technical Specification
Table 3.3-8 be operable, and that each of these channels be
demonstrated operable by performance of the channel checks and
channel calibration at the frequencies shown in Technical
Specification Table 4.3-5.
The inspector eviewed calibration records for the primary and backup
,
meteorological systems which showed that the systems were calibrated
'
in April 1988.
No violations or deviations were identified.
11. Collocated TLDs (25022)
The inspector verified the location of collocated NRC and licensee TLDs
and collected the data required by the Temporary Instruction.
No violations or deviations were identified.

12. Environmental Reports (80721)
a.
Technical Specification 6.9.1.8 requires the submittal of an annual
Radiological Environmental Surveillance Report.
The inspector
reviewed the report for calendar year 1986.
Generally, the resultu
were as expected with no trends noted. Naturally occurring activity
was observed in sample media in the expected activity ranges.
Fission-related isotopes resulting from the Chernobyl accident were
detected in the vicinity of the plant from early May through June.
At other times, occasional samples showed the presence of man-made
j
isotopes, which were discussed in appropriate parts of the report.
l
These activities were at very lcw concent:ations and had no
significant dose consequence.
No violations or deviations were identified.
13.
Followup of Significant Events (93701)
During the period of December 1-5, 1986, a control room habitability
survey was conducted at North Anna Units 1 and 2 by members of NRC (NRR
and Region II) and NRC consultants.
During this evaluation, flow tests
were conducted on the control room emergency ventilation system. The flow
tests showed that all four subsystems had flow rates in excess of the flow
rates specified in Technical Specification 3.7.7.
The NRC determined that
these high ficu rates could result in control room personnel receiving
doses greater than 5 Rem during an accident due to shorter iodine
residence times in the charcoal adsorber beds.
As a result of this
finding, the licensee issued Licensee Event Report (LER) 86-019-00.
According to the LER, the cause of the incident was inadequate post
maintenance testing af ter filter (demister) cleaning.
No cleaning
procedure existed to ensure post maintenance testing.
The inspector verified that procedures had been issued (PM-M-10-Fl./R-3 and
PM-M-20-FL/R-3) which provided for cleaning the demisters and performing
Periodic Tests (1-PT-76.12A, 1-PT-76.12B, 2-PT-76.12A, and 2-PT-76.12B) to
perform post maintenance testing on the control room emergency ventilation
system.
(Closed) LER 86-019-00.
