referenced inspection report.
1)
86-27-01 (Paragraph 4.3.1)
The equipment problems identified during the performance test must be
' ,
'
resolved to ensure PASS sampling capability. In addition, the schedule
for correcting these problems should be provided as requested during the
exit interview.
A.
Leakage in the dissolved gas sampling line.
Response:
1
A plant trouble report (4M3100340) has been generated. Any corrective
actions necessary will be completed by March 31,1987.
B.
Flushing pump tripped five times during performance test.

C.
Pressure indicator was slow to respond and did not stabilize.
Response:
The pressure indicator was serviced and it was found to function
properly.
D.
Operation of a valve (V-46) which isolates the containment
atmosphere sampling line was hampered for one hour when its

high level samples.
o
Demonstrate that plant personnel can collect, replace and
transport samples within GDC-19 limits.
o
incorporate silver zeolite filters in lieu of charcoal prior to
switchover to silver loaded silica gel, in order to reduce potential
radiation levels due to retained noble gases and to assure a
representative sampling technique.
These items will be reviewed during a future inspection. In addition, the
schedule for this item should be provided as requested during the exit
interview.
Response:
An engineering evaluation is being conducted to address the above items.
It is NNECO's intention to complete the evaluation by December 31,
