Exit Interview The inspection scope and findings were summarized on March 29, 1979, with those persons indicated in Paragraph I above.
3.
Licensee Action on Previous Inspection Findings (0 pen) Open Item (338/78-28-02) Correlation of ef fluent radiation monitors.
Special Test Procedure (ST-3) has the same deficiencies as the original Startup Procedure (SU-43) for this purpose. Licensee agreed to prepare a Health Physics Procedure for meaningful correlations by May 1,1979.
(Closed) Open Item (338/78-28-05) FSAR reference to resin solidification.
Change No. 65 revised FSAR Section 11.5.2 regarding resin solidification.
This item is closed. Further questions regarding resin solidification will be addressed through technical specification revision.
(Closed) Open Item (338/78-;28-04(b)) Unique identification of design change.
Design Change 78-67, pertaining to the contractor-supplied liquid waste demineralizktion system, was reviewed by SNSOC 10/17/78 and is still at the Corporate Office for review.

-2-(Closed) Open Item (338/79-03-02) Calibration procedure for portal monitor.
The procedure was approved on 3/29/79.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Leak Tests of Scaled Sources An inspector reviewed sealed source inventory and leak test records, and determined that the tests were conducted as required of T.S. 3/4.7.11. All test results had indicated less than 0.005 microcuries removable contami-nation.
6.
Effluent and Process Radiation Monitors (Unit 2)
a.
An inspector observed the status of installation of radiation monitors in the Unit 2 containment, turbine, and auxiliary buildings.
Two of four area monitor detectors (Containment Building) were not yet installed.
The condensor air ejector monitor, steam generator blowdown monitors, and reactor coolant letdown monitors were observed to be in place. The containment gas and particulate monitor was installed but not all internal piping was complete. A licensee repre-sentative stated that the discharge tunnel monitor was installed.
b.
An inspector reviewed preoperational test procedure 2-P0-10, " Radiation Monitoring System", and determined that testing of radiation monitor trip functions is included.
Testing had not been completed. The inspector discussed radiation monitoring system (RMS) calibration status with instrument technicians, who stated that the Unit 2 RMS calibrations were about 65% complete.
c.
In discussing instrument calibration procedures for RMS, an inspector determined that the isotopic source calibrations involve only one source for each detector. A licensee representative said that the instrument supplier had provided two sources of dif ferent activity levels for each of two isotopes, but only the one higher activity source was used in calibrating each detector. The inspector stated
that a two-point calibration check (excluding zero or background)
would provide a better calibration and that, based on a review of the technical manual, it appeared that the intent of the instrument supplier was that two sources be used for each detector. Licensee management stated that the RMS calibration procedures would be re-evaluated. (339/79-20-01)
d.
In observing the containment gas and particulate monitor, an inspector noted that there appeared to be sharp bends in the sample lines that could af fect representative sampling. Licensee management 2266 530

-3-stated that the question of representative sampling would be evaluated.
(339/79-20-02)
7.
Filter Systems (Unit 2)
An inspector observed that the containment recirculation filter systems (two) were installed within concrete shields, as described in FSAR 9.4.9.2.
The Engineering Supervisor stated that arrangements for testing these filters was the responsibility of the construction group, but that the test results will be reviewed by station management after the system is turned over.
