2.0 Status of Dreviously Identified Items 2.1 (Closed) Violation (50-289/87-01-01) concerning the generic deficiencies in the auditability of the EQ files.
Duri.g the January 1987 team inspection, the team determined that TMI-I EQ files were not inaintained in an auditable form to permit verification that each item of electrical equipment was qualified for its application.
A Notice of Violation (NOV) was issued to the licensee on December 29, 1988. This item was identified as item 2 in the NOV.
Subsequent to the inspection finding, the licensee updated and reformatted their EQ files extensively during the 1987 and 1988 period. As a result, the quality of the EQ files improved substantially. During this inspection, the inspector reviewed a sample of 7 EQ files listed below:
EQ-TI-129 for Rosemount Transmitters, Revision 2
EQ-TI-156 for Eaton Cable, Revision 1
EQ-TI-136 for Weed RTD, Revision 3
EQ-TI-150 for Rockbestos Cable, Revision 3
EQ-TI-162 for Kerite Cable, Revision 1
EQ-TI-289 for Bracd-Rex Cable, Revision 1, and
EQ-TI-122 for Foxboro Transmitters, Revision 2
These files had consistent formats and were easy to tudit. The qualification documents were arranged in a logical manner.
For each EQ file, a positive statement by the licensee that the equipment is qualified for its application was made, signed, dated and approved.
The important parameters are addressed in the following sequence:
SRS-1 for equipment description, function and service; SRS-2 for similarity analysis; SPS-3 for mounting configuration; SRS-4 Vor interfaces; SRS-5 for thermal aging; SRS-6 for radiation qualification; SRS-7 for mechanical and electrical cycling; SRS-8 for specimen test sequence; SRS-9 for performance and acceptance criteria; SRS-10 for post accident exposure; SRS-11 for chemical and water spray; SRS-12 for submergence qualification; SRS-13 for addressing test anomalfes and justification; SRS-14 for identifying and addressing applicable IEN, IEB, and TER.
The licensee stated that all of the TMI-1 files
!

.
-.
have been updated to this new format except those for the Limitorque
. Valve operators (EQ-TI-103, 104,:105).
The EQ files for the Limitorque Valve operators were also substantially updated.
However, the new format was not used because of the complexity of the limitorque operator filt The inspector conclude 6 that the licensee's corrective actions for thfs item are adequate.
This item is closed.
2.2 (Closed) Unresolved Item (50-289/87-01-02)' pertaining to the qualifi-
'
cation of Eaton Cable.
During the January 1987 team inspection, the inspector identified that during the second temperature transient of the test, the cable insulation resistance dropped to 2.84 X 10' ohms.
The reason for this occurrence was unknown and the test anomally was not addressed nor was it justified in the EQ file.
Subsequent to the finding, the licensee generated a Design Change Notice (DCN-048156)
dated January 13, 1987, providing a. justification for the test anomaly.
During this inspection, the inspector reviewed the updated EQ file and verified that this information was documented in section SRS B-13 of the EQ file.
This item is closed.
2.3 (Closed) Violation (50-289/87-01-03) pertaining to the qualification of black cam shafts used for Limitorque MOVs RC-V-3 and WD-G-3 located.inside the reactor containment.
These cam shafts were different than those previously established to be qualified. The Notice of Violation was sent to the licensee on December 29, 1988, identifying this item as item 3 of a Level IV Violation. Subsequent to the inspection finding in 1987, the licensee generated Design Change Notice (DCN) 048169 (dated January 18,1987) in which the licensee used similarity analysis to qualify the black cam shafts.
The licensee stated that all of the black cam shaf i inside the containment had been replaced by brown ones (made o1 cibrite) which had been qualified by test for application inside the :ontainment.
In DCN 048169, the licensee performed a similarity analysis between the black cam shafts and red cam shafts, both made of Durez material.
The red cam shaft had been tested per Limitorque Report B0003 for application outside the containment.
The specimen in Test Report B0003 was subject to steam environment at 25 psig and 250 F, while the TMI-I post LOCA profile has a temperature spike above 250 F for an initial period less t~ nan 100 seconds. The licensee performed a thermal-lag analysis to demonstrate that the temperature spike is not a concern. The inspector had no further question.
This item is closed.

3 2.4 (Closed) Violation (50-289/87-01-04) pertain Mg to the qualification of Rockbestos Cable (File No. EQ-TI-150). At the time of the inspection
'
on January '21,1987, the NRC determined that the EQ file did not co,itain sufficient information.to establish qualification for this type of cable. This item was determined to be part of a level IV violation.
The NOV was issued to the licensee on December 29, 1988, identi fying this as item 4 in the NOV. Two types of cross-linked polyethylene (XLPE) insulated cables were installed at TMI-1, KXL-760D with chemically XLPE compound and KXL-760G with irradiated XLPE compound.
The licensee has substantially updated their EQ files subsequent to the EQ team
<
inspection. The inspector reviewed EQ-TI-150 and found that two reports, Rockbestos OR-5804 dated October 24, 1985, and Rockbestos OR-5805 dated October 3, 1985, have been included in the file.
The first report documented the test of Firewall III Cable samples insulated with chemically XLPE KXL-760D compound while the second report docu-mented the test of Firewall III cable samples insulated with irradiated XLPE KXL-760G timpound.
In addition, similarity analyses (for both types of cable) between the installed cable and the tested cable were documented in the EQ file.
This item is closed.
2.5 (Closed) Violation (50-289/87-01-05) pe. taining to the qualification of Weed RTDs.
This item was identified as item 5 of a Level IV Violation in the NOV issued to the licensee on December 29, 1988.
Four models of Weed RTDs were installed at TMI-1.
They are: IAOD/611, IA90/612D, N90170 and N90175. The two models used as samples in the qualification test were: 611 and 612.
The licensee performed similarity analyses between the installed model and the tested model on March 3,1988 and documented the analysis in the Weed RTD EQ file (File EQ-TI-136).
The inspector reviewed these analyses and found them acceptable.
The evaluation of thermal aging, radiation, and post LOCA conditions was performed by the licensee on March 3, 1988 and documented in sections SRS A-5, SRS A-6, and SRS A-10, respectively, in the EQ file.
In addition, an error analysis of the test results was documented as SRS A-9 and Reference 136-08 in the EQ file.
The inspector had no further concern and this item is considered closed.
2.6 (Closed) Violation (50-289/87-01-06) pertaining to the qualification of Foxboro pressure transmitters (File No. EQ-TI-122).
This EQ file documented the qualification data for 6 Foxboro Model E11GH and E11AM transmitters, with Plant Tag Nos. RC3A-PT3, RC3A-PT4, RC38-PT3, PT-282, PT-285, and PT-288. The licensee stated that they had issued a Design Change Notice (DCN-063039) dated July 15, 1988, which deleted PT-282, PT-285 and PT-288 from the EQ Master List.
Eventually these three transmitters will be deleted from the EQ file.
The similarity analysis between the tested sample and the transmitters installed at TMI-1 was discussed in section SRS A-2.
The performance and acceptance criteria were discussed in section SRS A-9, pages 2 and 3.

l 2.7 (Closed) Unresolved Item (50-289/87-01-07) pertaining to the qualifica-tion of Rosemount Transmitters (File No. EQ-TI-129).
This EQ file has been updated extensively to conform with the new format.
The old
" checklist" item 8 for beta radiation, as stated in Inspection Report 87-01, is no longer applicable.
The radiation qualification for Rosemount Transmitters is discussed in section SRS A-6.
The inspector reviewed section SRS A-6 and noted that the beta dose and the attenua-tion due to the stainless steel transmitter housing were included in the TID calculation.
This item is closed.
2.8 (Closed) Potential Enforcement Item (50-289/87-01-09) pertaining to the qualification of Brand Rex Cable (File No. EQ-TI-153).
The licensee updated their EQ file for Brand Rex Cable. The cable's performance and acceptance criteria were addressed in sections SRS A-9 and SRS B-9.
The minimum insulation resistance values measured during the LOCA tests were properly discussed.
The inspector reviewed these acceptance criteria and fcund them acceptable.
This item is closed.
2.9 (Closed) Violation (50-289/86-06-07, Item 1) pertaining to the I
qualification of Kerite FR Cable.
This item was first identified as j
part of an apparent violation in the 1986 PAT team inspection. During the EQ enforcement evaluation in 1988, this item was determined to be part of a Level IV violation. The Notice of Violation (NOV) was issued to the licensee on December 29, 1988, identifying this as item 9 in the NOV.
Subsequent to the identification of this item in 1986, the licensee i
set up an EQ file for this cable, File No. EQ-TI-162 entitled
"Kerite FR Insulated Cable." During this inspection, the inspector l
reviewed EQ-TI-162 for qualification information such as temperature
{
and pressure profiles, thermal aging calculations and radiation l
qualification, and found it to be acceptable.

This item was first identified as part of an apparent violation in the 1986 PAT team inspection.
The subject cable was subsequently replaced. This issue was later determined to be a potential violation. On August 24, 1988, an enforcement conference was conducted with the licensee to discuss this item. A presentation was made by GPU on the background, identi-fication and corrective actions for this item.
Following the enforce-ment conference, NRC evaluated the information presented by the licensee, and determined that this item is no longer considered a violation.
This item is closed.
2.11 (Closed) Inspection Followup Item (50-289/86-06-08) concerning the need for an additional NRC inspection of licensee's EQ program. An EQ team inspection of the TMI-1 EQ program was conducted on January 12-21, 1987 (inspection report no. 50-289/87-01). During that inspection, the team members reviewed the licensee's implementa-
,
tion of the EQ program, selected a sample of 31 EQ files for review, I
and physically examined the installed conditions of representative EQ equipment. At the conclusion of that inspection, the team determined that TMI-1 has implemented a program to meet the requirements of 10 CFR 50.49.
This item is closed.
3.0 Exit Meeting This inspector met with licensee personnel (denoted in Details, paragraph
!
1.0) at the conclusion of the inspection on April 6, 1989 at the corporate office. The inspector summarized the scope of the inspection and the inspection findings. At no time during the inspection was written material given to the licensee.
