Decontamination Startup and Test program i
Scope The thrust of this inspection by a Region 1 inspector was to develop a Preoperational and Startup Test Inspection Program for the preuserational portion of the Decontamination Startup and Test Program at TMI Unit 2.
i
!
Because this is a Recovery and Decontamination Program for TMI Unit 2, the following are considered as minimum for an adequate startup and i
j test program:

Discussions The inspector met with the Startup and Test Manager, TMI Unit 2 to discuss the licensee's decontamination startup and test program.
Discussions centered on test program requirements and implementation; test procedure reviews and verifications; test witnessing and test results evaluations; and, testing of new or modified systems.
_
The inspector reviewed the startup and test manual, various procedures, a typical test scheduling and sequencing chart, system diagrams and a sampling of turnover packages from construction to startup testing.
Findings l
As a result of the discussions with the Startup and Test Manager and l
his group; a review of the referenced documents: and inspection of a l
system in the construction phase (Submerged Cemi.ieralizer System), no discrepancies were noted.
The inspector concluded that based upon the selected sample taken, the Itcensee's Decontami. nation Startup and Test Program for TMI Unit 2 appears acceptable.
The inspector had no further questions at this time. These areas of the startup anc test program will be followed up on subsequent inspections.

Discussions The inspector met with the Startup and Test Manager TMI Unit 2 and discussed the Submerged Demineralizer System and the SDS Construction and Startup Test Program.
Included in the discussions were the areas of the preoperational portion of the startup test program, including requirements and implementation; procedures for flushes, hydros, testing and operation; system and/or component turnovers, test scheduling, test sequencing and test witnessing; the Submerged Demineralizer System walkdowns; and, the inspectors review of the reference documents.
The inspector also discussed with the licensee's representative, procedure reviews and verifications, test witnessing and test results evaluations which would be done on a sampling basis by NRC IE inspectors.
Findings As a result of discussions witn the licensee's reprt;entatives, re-views of referenced documents and several tours of the SDS system and the refueling area, the inspector determined the following:
a.
Requirements and implementation of the preoperational and startup test program fm the SDS system have been addressed for the following areas:
test program and test organization, test program administration and document control, changes and modifications, maintenance and surveillanct, equipment protection and cleanliness, test and measurement equipment, and training and
--
qualifications.
b.
Procedures exist for flushes, hydros, preoperational, startup and functional tests for components and evolutions of SDS system testing. They address the following:
.
Management review and approval;

--

--

--
and test data; and, Independent verification of critical steps or parameters.
--
c.
Turnovers, test scheduling and test sequencing from construction tu startup and test, to operations have been addressed through admiristrative procedures, flow paths for construction, startup
'
and test logic diagrams;' test sequence documents and SDS and
. _
related system. diagrams.
d.
Several visual inspections were made of the Submerged Demineral-irer System through walkdowns of ne system and refueling area.
Visual inspection and observations were made of system arrange-ment, components, piping, hanger supoorts, electrical cabling, instrumentation, system integration and interrelated system connections. Attention was also given to lighting and radiation monitoring of the area, as well as equipment protection and cleanliness.
,
No items of noncomoliance were identified.
The inspector concluded that the licensee has an acceptable test procram for the preoperational
portion of the SDS Construction and Startup Test Program at TMI Unit
~

NRC IE Insoector Observations Resulting from inspector reviews, discussions and visual inspections, the following items were identified for additional evaluation and resolution:
I a.
Adequacy of piping support in some areas around the valve man-l ifolds on the refueling floor, b.
Adequacy of the number of area radiation monitors (fixed and/or portable) in the refueling area.
c.
Adequacy of communications between the SOS operating areas on the refueling floor and the Unit 2 Control Room.
d.
Adequacy of emergency lighting for the refueling area.
Adequacy of procedures for handling a total loss of station power e.
(during functional oper: tion of the SDS).

f.
Adequacy of Procedures for handling emergencies and abnormal occurrences such as:
(1)
fire (2) high radiation alarm (3) contamination of an individual (4)
an individual falling off of the platform into the fuel pool (5)
fainting or unconscious individual (6)
First aid for personnel (cut, bruise,etc.)
(7) quick removal of a person from refueling floor if necessary g.
Adequacy of high radiation sweeps af entire area when system is put into operation and periodically thereafter.
h.
Adequacy of overpressure protection in the SDS system as well as the interrelated adjacent systems.
1.
Neec for a central control point or control station for the SOS operation.
.
J.
Need for a designated person to be in charge at all times during functional operation of the SDS system.
k.
Need for restrictions or strict control of movement of the overhead
._
crane over the refueling pools during processing.
1.
Need for recording operations and evolutions in a log on the refueling floor during process'ng.
m.
Need for flow charts and/or diagrams on the refueling floor during operation. Need for installation, of valve position indicators at ecch reach rod penetration at aach of the valve manifolds on the refueling floor, so that valve position can be readily ascertained.
These items were brought to the attention of bcth the licensee and NRR personnel at the exit meeting. The inspector recognized the fact that many of these items are beyond the scope of the preoperational &
startup test phase and may be add" ssed in operating and emergency pracedures.
5.
Ex't Interview An exit meeting was conducted on March 26, 1981, with the licensee's senicr site representatives (denoted in paragraph 1).
The findinas were identified and the inspection program was discussed.
