Management Interview A management interview was conducted with Mr. Evans and other members of the licensee's staff at the conclusion of the inspection on May 27, 1976. The following items were discussed with the licensee representatives.
A.
The inspector reviewed the scope of the inspection and stated that no items of noncompliance with regulatory requirements had been identified.
(Paragraph 2, Report Details)
B.
The inspector noted that process and effluent monitors were to i
be cross calibrated to contractor performed fluid calibrations upon installation.
The inspector cautioned the licensee to ensure that documentation was available to substantiate the validity of the contractor's calibrations and the licensee's
'
-
cross calibrations.
The licensee stated-that appropriate documentation would be maintained.
(Paragraph 7.b, Report Details)
x
,
C.
The inspector stated that isokinetic sampling requirements, radwaste tank volume determinations, and gas decay tank monitor ficw characteristics would be examined during a subsequent inspection.
D.
The inspector noted that area radiation monitor calibrations
!
currently in progress included a calibration point within the normal instrument operating range and that the alarm system for the area radiation monitoring system had been modified to incorporate a "reflash" capability.

General This inspection was conducted to examine the construction status of the licensee's radioactive liquid, gaseous, and solid waste systems, including process and effluent monitors.
The status of preoperational test, calibration, and operating procedures was also examined.
The licensee's responses to
..
previous radiation protection inspections were reviewed.
No discrepancies from regulatory requirements were identified during the inspection.
3.
Organization The licensee's Chemistry and Health Physicis Department organ-
[
.
ization has been enlarged to include two additional Chemistry

and Radiation Testor positions.
The additional Testors and an Assistant Health Physicist have been hired since the previous radiation protection inspection. All department positions are currently filled.
,
4.
Training According to the licensee's records, two specialized radio-chemistry training sessions have been conducted since the previous radiation protection inspection. The training sessions addressed radiochemistry counting room techniques, laboratory equipment calibration, and reagent preparation.
The general orientation training videotape presentation has not been completed.
The licenset expects to commence using the videotape for training contractor personnel as well as new station employees by mid-year.
The
,
'
videotape presentation will be reviewed during a subsequent inspection.

Area Radiation Monitoring (
)
The licensee was calibrating the thirty-thr'ee area radiation monitors during this inspection.
The calibration procedures, IC 2005.01 and IC 2005.02, were noted to have been appropriately reviewed and approved. The calibra"_ ion procedures had been revised, since the previous radiation protection inspection, toincludecalibrationpo{ptswithinthenormaloperating range of the instruments.-
According to licensee personnel, an alarm system incorporated into the process computer will include the area radiation monitors.
The alarm system will have a "reflash" capability.
Calibration documentation, including alarm operation, will be reviewed during a sub-sequent inspection.
6.
Construction Status a.
Liquid Radwaste System Major piping, storage tanks, and filters /demineralizers were noted to be in place; electrical work and minor piping connections remain to be completed in both the clean and miscellaneous radioactive waste systems.
No discrepancies from FSAR descriptions were noted in
-
either of the liquid radwaste systems.
Present construc -
--
tion schedules call for turnover of the liquid radwaste --
systems to the licensee by August 1976.
Preoperational (
testing is scheduled to commence subsequent to turnover.

U}
b.
Caseous Radwaste System Major piping and components (decay tanks, surge tank, com-pressors, and filters) were noted to be in place; electrical work and minor piping connections remain to be completed.
No discrepancies from the FSAR description of the gaseous radwaste system were noted. Present construction schedules call for turnover of the gaseous radwaste system to the licensee by September 1976. Preoperational testing is scheduled to commence subsequent to turnover.
.
c.
Solid Radwaste System Piping and component installation was partial 1r completed; the solidification and drumming components had not yet been installed.
Present construction schedules call for turnover of the solid radwaste system to the licensee by August 1976. Preoperational testing is scheduled to com-mence subsequent to tienover.

Process and Effluent Monitors ('_ /.
-
\\
\\,_,
a.
General The licensee's process and effluent radiation monitors
-
.
utilize beta or gamma scintillation detectors with analyzers
'which allow selective energy discrimination Installation
.
of the monitors had commenced shortly before this inspection.
The licensee's current plans specify monitor installations at the locations designated in the FSAR.
Several monitor locations in addition to those specified in the FSAR are planned. One of the monitoring additions is in the station external drain system (nonradioactive system).
Licensee personnel stated that two monitors would be utilized in series in selected installations, while other, less critical, installations would consist of a single monitor.
In either case, the licensee's present intentions are to monitor gross activity with at least one monitor, with the possible exception of certain gaseous monitors which may be set to selectively monitor Xe-133 or Kr-85.
Licensee personnel stated that
.
the monitors' operating settings would be specified in the system operating procedure (SP 1105.07).
This procedure will be reviewed during a subsequent inspection.
b.
Calibration The licensee intends to install the process and effluent
-.
(
h monitors, utilizing calibrations performed at th4 contractor.'s x,, /
facility. The inspector examined the contractor's calibration data for the following monitors:
station effluent (RE 8433);
miscellaneous radwaste (RE 1878A,B); clean radwaste (RE 1770A,B);
radwaste gaseous discharge (RE 1822A,B); and station vent stack (RE 2024A,B,C and RE 2025A,B,C).
The inspector requested the licensee to clarify the following items noted during review of the calibration documentation: (1) the linearity and calibration curves were generally derived for classes of monitors rather than for specific detectors; (2) linearity curves were not available for the beta scintillation detectors; j
(3) calibration curves were not available for RE 2024A and RE 2025A; and (4) the calibration curve attributed to RE 2024B and and RE 2025B did not reference the applicable monitors.
These items will be examined further during a subsequent inspection.
Licensee personnel stated that they intended to utilize dis-crete sealed sources supplied by the contractor to calibrate the monitors. The discrete sealed sources were cross

{'~'N calibrated to liquid or gaseous standards by the contractor.
_,)
For most monitors, only one activity cross calibration sourec y
was available. The majority of the cross calibrations were
~
noted to have bee. performed with a wide open encrgy window setting, even through several of these monitors will be operated with a relatively narrow energy window.
The inspector requested the licensee to clarify the adequacy of cross calibrations performed at a single activity or at an energy window. setting other than the operating setting.
These items will be examined during during a subsequent inspection. Licensee personnel stated that isokinetic-sampling probes received from the contractor would be checked for proper flow characteristicsduring the preoper-ational testing.

Procedures System operations, ca ? th::stion, and administrative control pro-cedures related to ec
- .rvon of the gaseous, liquid, and solid radwaste systems have,sen completed, except for the following:
SP 1104.28 (Solids Radwaste Disposal); AD 1850.02 (Solid Radio-active Waste Processing and Handling); AD 1850.03 (Radioactive Gaseous Release); and IC 2005.05 (Process Radiation Monitor

liquid waste disposal system (TP 230.01,.02,.03), the gaseous radwaste disposal system (TP 232.01), and the solid waste disposal f(,)
procedures asacciated with the radwaste systems will be reviewed
\\
system (TP 233.01,.02) have not been completed.
