The procedure also states acceptance criteria and instructions for actions to be taken if the criteria are not met.
t 3.0 Training and Qualifications
In a previous inspection (50-423/85-65), a representative of the lic.ensee's chemistry training organization stated that additional refresher training l
and testing would be provided to three NNECO chemistry technicians who had
not passed examinations covering refresher training in nuclear physics, j
math, and/or chemistry. No decision had been made as to what action would
!
be taken if these technicians failed the subsequent tests.
The inspector will review the licensee's actions in this area in a future inspection,
f l
+
.
.
A chemistry department representative stated that contractor chemistry technicians would not receive the on going training that is provided to NNECO chemistry technicians because the contractor technicians are not expected to remain at the site indefinitely; they are primarily needed during startup.
The licensee also stated'that contractor technicians are permitted to perform required surveillance sampling and analyses under the direction of a qualified NNECO chemistry technician, although it is not considered necessary or feasible for the contractor technician to be in the presence of a NNECO technician while performing these activities.
Contractor technicians are not permitted to sign the surveillance docu-mentation forms.
The inspector stated that if contractor technicians are to be utilized indefinitely, they should be included in the training program and be qualified to sign surveillance forms.
The licensee stated that its long term plans have not been finalized.
The inspector discussed with the licensee the need to independently docu-ment the qualifications of its contractor chemistry personnel in order to demonstrate that these personnel meet the criteria of ANSI N18.1 - 1971.
The licensee stated that this documentation would be completed by Februa ry 28, 1986.
These issues will be reviewed in a future inspection (50-423/85-42-01).
4.0 Facilities and Equipment The inspector noted that all Phase II tests concerning liquid and gaseous waste processing systems have been completed or are nearing completion.
The waste evaporator portion of the liquid waste system (LWS) was still being tested at the time of this inspection.
This portion of the LWS is not needed to support the power ascension phase of the facility startup program.
The remainder of the LWS has been tested and is functional.
There is just one Phase 11 test procedure covering all filtration system component (HEPA and charcoal) testing; at the time of this inspection, the following filtration systems had been tested and had been reviewed and noted in the minutes of the Joint Test Group:
Control Room Emergency Ventilation, Auxiliary Building, and Supplementary Leak Collection and Release System (SLCRS).
These systems are required to support the various modes of operation during startup.
The remaining system required by Technical Specifications, the Fuel Storage Pool Air Cleanup System, is not required to be operable until irradiated fuel is in the storage pool.
This system has not yet been tested.
The Containment Air Filtration System, which is not required by Technical Specifications, has been tested, but the results had not yet been reviewed at the time of this inspection.
The entire test procedure (3-INT-2008), including the five appendices which cover the individual system tests, will receive final review and acceptance after all tests have been successfully complete.

,
Phase 11 testing of the Radiation Monitoring System (RMS) has been
completed.
This test verified the communications capability between
]
individual monitors and the RMS computer. The majority of monitors are fully functional.
Some problems exist with individual units, involving alarms for high or low pressure, temperature, flow, or conductivity in
liquid process' lines.
Such problems can usually be attributed to changing l
conditions within various systems as the plant testing program progresses.
,
These are one or two instances each of detector failure, alert, or high
!
radiation alarms. As there is no appreciable radioactivity in plant l
)
systems, the alert and high radiation alarms are due to other causes;
{
e.g., loss of flow.
The licensee stated that problems are investigated
,
- '
as they occur, and corrected as quickly as they are diagnosed and parts
'
become available.
The inspector reviewed the status of the RMS and r
concluded that the system as a whole was operational, that the majority of
monitors were operational, and that the problems with individual monitors
'
were not a cause for concern at this time. The status of the individual i
L
!
RMS monitors is given in Attachment I.
A number of problems noted in the i
previous inspection of this area (50-423/85-65) have been corrected and l
thus no lenger appear in the comments section of the list.
The licensee stated that due to problems with the shielded cable supplied by the RMS manufacturer, one of the original Kaman Containment
,
!
High Range Monitors (3RMS*RE05) could not be installed prior to closing
the containment..The other Kaman high range monitor (3RMS*RE04) was
!
installed with a shorter cable at a location different from that orig-inally specified.
Sufficient usable cable was available to make this
,
i installation possible.
The licensee stated that a new high range monitor
!
(3RMS*RE05A), supplied by General Atomic, had been installed near the
location originally specified for 3RvS*RE05.
The installation, including cable, is complete up to the point of containment penetration.
The cable installation from the point of penetration to the control room has not I
been completed.
The licensee intends to install a second General Atomic
high range monitor (3RMS*RE04A) near the location originally specified for l
3RMS*RE04, probably during the first refueling outage.
No decision has
!
been made as to whether the two Kaman and two General Atomic monitors will supplement one another over the long term. Both systems will have direct i
l indication in the control room, but the General Atomic monitors will not j
interface with the RMS computer system.
The inspector stated that the j
status of the RMS would.again be examined during a subsequent inspection l
(50-423/85-19-01).
i
i 5.0 Dlans and Procedures
Phase II test procedures for the BRS, GWS, and RMS have been completed,
,
'
as have those portions of the LWS and filtration systems test procedures
,
necessary to support power ascension.
Review and acceptance of the test
!
results by the licensee's management will be examined in a future inspection.
Additional testing to be performed during power ascension i
include:

The completion, review, and acceptance of Phase II and above tests for the LWS, BRS, GWS, filtration systems, plant chemistry, and RMS will be
'
!
examined in a future inspection (50-423/86-06-01).
i
.
Startup Test No. 29. " Process and Effluent Radiation Monitoring System,"
which is described in Table 14.2-2 of FSAR Chapter 14, states, under Test i
Objective and Summary:
"This test will verify the operability of process and effluent radiation monitors.
... Samples will be taken at monitored points and analyzed, The results of the analysis will be compared to the readings of the monitor." The Acceptance Criteria for the test include the following statement:
"The process and ef fluent monitor responses are consistent with sample results." The inspector reviewed 3-INT-8000,
.
Appendix 8007, " Radiation Monitoring System," and noted that this test
),
procedure did not contain provisions for comparing process and effluent monitor readings to the results of analyses of samples taken at monitored j
points.
This was not considered an item of noncompliance because no j
testing had yet been performed.
The li
'see initiated a test change to add the necessary instructions and data mets to the test procedure for
'
monitors required by Technical Specifica61ons and/or by virtue of their
importance in monitoring real-time plant status and discharge paths to the l
environment.
The response of these monitors versus sample results will be
'
examined in a future inspection (50-423/86-06-02).
j l
i Chemistry analytical and surveillance procedures have been written and
'
approved. One RMS surveillance procedure and five generic (I&C) proce-i dures have not yet been approved.
These are in development or review
!
(50-423/85-19-02).
i
j 6.0 Exit Interview i
i The inspector met with the licensee representatives (denoted in Paragraph 1) at the conclusion of the inspection on January 31, 1986,
,
and summarized the purpose and scope of the inspection and the inspection i
findings. At no time during this inspection was written material provided
,
to the licensee by the inspector.
