Facilities Radiation Protection Section Inspection Summary Inspection on January 26-27 and February 5-6, 1981 (Report No. 50-373/81-04 Areas Inspected: Routine, unannounced preoperational inspection of the radiation protection program, including:
organization; personnel qualifi-cations and training; instrumentation; preoperational testing of the Area Radiation Monitoring System; radiation protection procedures; and portable survey meter capabilities and calibration. Also reviewed was the location of the containment monitor and the location of valves in the solid radwaste system. The inspection involved 40 inspector-hc,urs onsite by three NRC inspectors.
Results:
No items of noncompliance or deviations were identified.

General This inspection, which began at 9:00 a.m. on January 26, 1981, was conducted to examine selected portions of the licensee's radiation protection program to assess readiness for fuel loading.
3.
Rad / Chem Technician (RCT) Training The licensee recently sent most station RCT's to Dresden for one week to participate in a refueling outage and acquire hands-on training.
During discussions with the inspectors, three RCT's stated that the training was beneficial. This training is in addition to the formal training program.
4.
Gaseous Effluent Monitoring New effluent monitoring equipment for the plant vent and standby gas treatment system vent is scheduled for receipt in April 1981.
A contract has been let to investigate and evaluate the isokinetic l
, sampling systems for the two vents. The preoperational testing
'
procedure is being written. This new equipment is in response to TM1 Lessons Learned requirements.
5.
Area Radiation Monitors (ARMS)
The inspector reviewed the locations of ARMS which are required to be
[
operational before initial fuel loading; three detectors are poorly (
positioned and may not perform their intended function because of intervening shielding.

Location 1-8 Tip Room 1-9 Rx. Bldg. Mezzanine Floor 1-12 Southeast RHR Hx.
Several other ARM detector or alarm / readout positions enuld be improved to better perform their function. These problems were discussed with
.
the licensee. No commitmert was made by the licensee to either review the need to relocate the instrumentation, or to make such relocations.
The inspector will continue to pursue this matter.
6.
Radiation Protection Procedures The inspector reviewed the following new or recently revised radiation protection procedures. They appear to be compatible with regulatory requirements and FSAR commitments:
LRP-1110-1, Revision 0, Maintenance of Radiation Records LRP-1120-1, Revision 1, Controlled Area Access LRP-1130-1, Revision 2, Radiological Signs and Labels LRP-1210-1, Revision 2, Exposure Report on Termination LRP-1210-8, Revision 1, Personnel Monitoring for External Exposures LRP-1280-2, Revision 1, Dose Rate Surveys LRP-1280-1, Revision 0, Green Diamond Surveys
'
LRP-1910-1, Revision 0, Radiation Protection Training for Escorted Visitors 7.
Portable Survey Meters An inventory and evaluation was conducted of the licensee's count rate and dose rate survey meters sensitive to neutron, alpha, beta and gamma radiations. The licensee's survey instruments were reviewed for conformance to FSAR Table 12.5-2 for quantities, sensitivites, ranges, and calibration frequencies. The FSAR commitments were met (in most cases exceeded) for all instrument types.
Construction of a well type calibration facility was recently completed.
The facility is used for all gamma source calibrations of survey meters except six high range (0-1000 R/hr) extendible probe survey meters.
.These six meters are returned to the manufacturer for calibration because the licensee's facility is inadequate for calibration of their higher ranges; The licensee plans to obtain a commercially available, portable, shielded calibrator containing 260-300 curies of cesium-137.
This device should be capable of calibrating the higher instrument ranges. The high range survey meters with extendible probes have a second detector at the handle end of the device to show the dose rate at that location. Since the licensee has no neutron calibration
!
source, the two neutron survey meters (third meter on order) are sent to Zion Nuclear Station for calibration.

,
The FSAR commitment for portable survey instrument calibration is annual, with quarterly functional checks. Recently developed cali-bration procedures specify quarterly calibrations at three points on each instrument scale (20%, 50%, and 80% of full scale). The inspector noted that several instruments had been inadequately calibrated on December 2, 1980.
Instrument scales were either not checked for calibration or were checked for calibration only at one point. The licensee agreed to promptly recalibrate these instruments and stated that an audit system is being established to identify and correct problems of this nature. This system will be reviewed during a future inspection. Calibration stickers are used on instruments.
Recalibration is required following any maintenance. The licensee has fabricated several devices, which utilize strontium-90 sourcer behind several plastic attenuators, for routine source response check of instruments.
Specialized instruments observed by the inspector included a mobile floor monitor and five Xetex digital dosimeters. The latter have preset alarm capabilities and a range up to 10 rems.
No items of noncompliance or deviations were identified.
8.
Rad / Chem Department Organization and Personnel Qualifications The inspector and a representative from the Radiological Assessment Branch, NRR, met with the licensee on January 26-27, 1981, to discuss open items concerning the Rad / Chem Department organization. The following topics were discussed:
'
a.
A QA manual change which allows the Rad / Chem Supervisor to report directly to the Plant Superintendent for matters concerning radi-ation safety.
b.
Qualifications of the radiation protection manager (Rad / Chem Supervisor).
c.
Separation of RCT personnel into separate chemistry and radiation protection groups.
These items will be reviewed further during future inspections.
9.
Selected Valve and Monitor Locations The inspector and the NRR representative reviewed containment monitor
,
locations and valve locations in the Solid Radwaste System. These items are still under evaluation by NRR, and will be reviewed further during future inspections.
10.
Exit Interview The inspector met with licensee representatives (denoted in Paragraph 1)
at the conclusion of the inspection on February 6, 1981 and by telephone with Mr. Bishop on February 27, 1981. The following items were discussed.
