Licensee Action on Previous Enforcement Matters
E
(Closed) VIO 85-25-01:
Failure to Have Adequate Procedures to Meet
Required Effluent Measurement Capability. The inspector reviewed relevant
procedures and discussed them with Count Room personnel.
The inspector
determined that the licensee's corrective actions were effectively
implemented.
4.
Radioactive Liquid Waste (84723)
Technical
Specification 3/4.11.1 establishes upper limits for..
concentrations- of radioactive material in liquid effluents. The inspector
selectively reviewed release records for January to May 1987.
All
releases reviewed were within technical specification limits.

Radioactive Gaseous Waste (84724)
Technical
Specification 3/4.11.2 establishes upper limits .for
concentration .of radioactive material in gaseous effluents. The inspector
!
reviewed selected waste gas decay tank releases .for ' January 'to May 1987.
}
'
All releases were within technical specification: limits.
No violations'or deviations were identified.
'6.
Radioactive Effluent . Monitoring Instrumentation (92717, 84723, 84724,
92701)
Technical Specifications 3.3.3.9 and 3.3.3.10 require radioactive liquid
and gaseous effluent monitoring instrumentation channels to be operable
'
with their. alarm / trip setpoints set ~in accordance with the Offsite Dose
Calculation Manual (0DCM).
Technical Specification Tables 4.3-12 and
4.3-13 establish frequencies for channel checks, source checks, channel
calibrations, 'and channel fuctional test operations.
. The inspector
selectively reviewed calibration and channel check records for June 1986
to May 1987. Calibrations and checks appear to be performed as required,
a.
- The inspector also reviewed the operational status of the licensee's -
Kaman high range noble gas and particulate monitors.
Over the past
year a marked improvement in.the reliability of these monitors was
noted.
The licensee has placed the electronics in air conditioned
cabinets to prevent overheating of sensitive circuitry. The licensee
has established . links with other vendors capable of supplying
replacement parts.
The inspector discussed emergency procedures to
be used in retrieving particulate filters and charcoal cartridges
under' accident conditions with cognizant licensee prsonnel.
Special
" reach" tools are located near the monitors to reduce the doses
received during retrieval operations.
The Health Physics qualified
technician that performs this operation has discretion to abandon the
retrieval if accident dose limits could be exceeded.
The licensee
utilizes environmental monitoring data as a backup'if samples cannot
' be retrieved from the effluent monitor station.
The inspector
concluded that the licensee has the capability, under accident
conditions, to moet the requirements of NUREG-0660,. Items II.F.1.2.A
(Noble Gas Monitor) and Item II.F.1.2.B (Iodine / Particulate
Sampling). These items are now considered closed.
I
b.
The inspector reviewed selected calibration and maintenance records
of effluent radiation monitoring systems.
The licensee was aware of
Information Notice 86-42, Improper Maintenance of Radiation
Monitoring System. The inspector noted that all operations involving
the systems reviewed were verified by an individual other than the
technician performing the operations.

The inspector noted that calibration checks are performed on the
j
proportional composite sampling pump associated with the sampling of
liquid effluents.
This pump has had some reliaoll.i_ty problems, but
1
the licensee has adequate backup procedures to ensure that a
'
representative composite sample can be obtained,

Post Accident Sampling System (fASS) (84723, 84724, 92701)
>
The inspector toureo PASS facilities and discusced operational hirtory
l
with cognizant licensee personnel.
The system in its present .
>
configuration has proven to be reliable With the exception of a vaedum
pump in the system.
The licensee is studying ways to increase the S
functional reliability of this' pump.

A monthly test program has been established to , insure that operatio.n and
performance capability of equipment and personnel are maintained.
The
s
,
inspector reviewed the results of this program for the past twelve months.
The licensee has demonstrated the ability to 'obtair. containment air
i
samples and containment sump samples.
The Pass is properly lighted and
a
'
sensitive equipment is provided with controlled ventilation.
1
On the basis of this insst:ction, and on the inspections of the PASS
j
previously reported in Report Nos. 50-338, 339/83-30, and 50-338,
339/84-40, the inspector determined that the North Anna PASS
was
installed, tested and inspected, and performed within the criteria
established in NUREG-0737
Item II.B.3, and is considered operable.
Continued operability will be established during future routine
!
inspections.
