Inspector Followup Items (Closed)
a.
(Closed) IFI (50-328/82-06-01) Start Up Shield Survey The inspector reviewed the licensee's Review of Startup Test SU-1.0 results pertaining to two survey points (RB-32 and RB-57) having higher radiation levels than projected by the FSAR. The radiation levels were not excessively higher, 100 mrem /hr vs 123.5 mrem /hr and 1G0 mrem /hr vs 220 mrem /hr, and the review justified the higher levels on the basis of location and controls over these areas which led to a decision to submit a request for an FSAN revision which had been prepared and was ready for dispatch. The inspector had no further questions.
b.
(Closed) IFI (50-327/82-35-02 and 50-328/82-34-02) Installation of Temporary Lead Shielding The inspector reviewed licensee procedure AI-33, Temporary Shielding of Radiation and discussed the procedure and methodology of full account-ability of temporary shielding with the individual responsible and determined that the program should be effective. The inspector had no further questions.
c.
(Closed) IFI(50-327/83-03-02 and 50-328/83-03-02) IE Bulletin 80-10, Procedures for Sampling and Analysis The inspector reviewed procedures SI-52, Monthly Chemistry Requirements and HPSIL-4, Health Physics Routines and discussed the procedures with licensee personnel assigned responsibility and determined that sampling and analysis of other systems such as demineralized water, service air and instrument air are now adequately covered. The inspector had no further questions.
,
d.
(Closed) IFI (50-327/83-03-05 and 50-328/83-03-05) ALARA Program The inspector reviewed licensee procedure RCI-10, Minimizing Occupa-tional Radiation Exposure, and discussed the ALARA program with the e
individual assigned fulltime responsibility for the program and deter-mined that the procedures are now complete and approved and the program functional. The inspector had no further questions.
e.
(Closed) IFI (50-327/83-03-06 and 50-328/83-03-06) Personnel Monitoring The inspector reviewed procedural changes and additional training relating to assurance that visitors and permanent plant personnel wear personnel monitoring devices as required. A special class on Escorting Responsibilities was given in February,1983 and all plant personnel were required to attend.
Site Specific Training includes Escort

Responsibilities and all visitors are required to complete this training before entering areas where personnel monitoring devices are required.
In addition, classes on the subject of Areas of Special Interest For Sequoyah Training, also includes Escort Responsibilities and is to be given on an annual basis. The inspector had no further questions.

Inspector Followup Items (0 pen)
a.
(0 pen) IFI (50-327 and 50-328/82-06-02) Contamination Control Program At the time of the last inspection a decision had not been made as to the permanent location of exit portal monitors. A licensee representa-tive stated that they will be permanently located in the corridor adjacent to the Health Physics laboratory (office) which was their location at the time of this inspection. The present Health Physics laboratory (control point) does not afford ease of viewing personnel exiting through the portal monitors and the audible and visual alarms are located on the monitors. The inspector informed licensee personnel and management that on a backshift he had noted poor surveillance by Health Physics of personnel exiting through the portal monitors. A new Health Physics laboratory was being built adjacent to the existing laboratory at the time of this inspection. Windows in the new facility will provide better viewing of the portal monitors.
The inspector stated that this item will remain open pending further observations on a future inspection of the surveillance of personnel exiting through the monitors after the new Health Physics facility has been completed.
b.
(0 pen) IFI (50-327 and 328/82-19-03) Auxiliary Building Noble Gas Airborne Problems The licensee has identified the Boric Acid Tanks as a source of air-borne noble gases End provided temporary venting through a filter system. Design Change Request No. P-1906 has been sent to TVA, Design Engineering in Knoxville, Tennessee for a permanent ventilation system on the tanks.
The inspector informed licensee management that the item will remain open pending completion of the permanent ventilation system.
c.
(0 pen) IFI (50-327/82-35-01 and 50-328/82-34-01) Post Accident Sampling System (PASS)
The inspector observed a portion of the PASS which had been installed, however, the system had not been completed. The inspector informed licensee management that the item will remain open pending completion of the syste..

Licensee Event Reports The inspector reviewed licensee Reportable Occurrence Report Nos.
SQRO-50-327/83083, SQRO-50-328/83073 and SQRO-50-328/83078 and determined that corrective action was prompt and effective for these three occurrences involving two radiation monitor failures and a clogged sense line in the flow rate measuring device for the shield building stack.
The inspector also determined that there have been no reoccurrences of these specific events and he had no further questions.
8.
Effluent Releases The inspector reviewed the licensee's records of liquid and gaseous radio-active effluents for the months of May and June, 1983 and noted no viola-tions with the requirements of the Technical Specifications or 10 CFR 20.
See paragraph 16 for detailed data.
9.
Reporting Requirements The inspector reviewed licensee reports for radioactive discharges as required by the Technical Specifications and found no violations.
10.
Radioactive Waste Packaging and Shipment The inspector observed the radioactive waste packaging and storage area and discussed these activities with the individual assigned direct respon-sibility.
The inspector had no further questions. The shipments of radio-active waste during May and June, 1983 are shown in paragraph 17.
11.
Posting and Labeling During plant tours the inspector observed posting and labeling and noted no violations with 10 CFR 19 or 10 CFR 20.
12.
Portable Survey Instruments The inspector observed various survey instruments and friskers throughout the plant and found them to be within timely calibration and apparently j
operating properly.
!
13. Radiation Work Permits i
The inspector observed work being performed under a work permit and noted no departures from the requirements of the work permit. An entry to con-tainment was observed on a backshift and the inspector noted that the personnel had to exit containment prematurely because needed materials were l
not taken in at the time of the initial entry. The inspector informed licensee representatives that this was an example of inadequate preplanning
'
l and poor practice. This was acknowledged by the licensee representatives.

14.
Contamination Control During the backshift on July 20, 1983, the inspector noted that Health Physics personnel were not maintaining surveillance over personnel exiting through portal monitors and friskers outside the Health Physics laboratory control point.
Licensee representatives were informed by the inspector that additional surveillance by Health Physics personnel over such activities is warranted. This will be observed during future inspections for improvement.
