Matters discussed and comments on the part of the management personnel were as follows: 1.
The inspector stated that the main purposes of this inspection were to review the status of previously identified unresolved matters, procedures relative to the Steam Generator Secondary Hydrostatic Test and to observe work being performed on the Hydro.
2.
The inspector stated that one of the previously identified ~ c unresolved items was being closed and the others remain open pending receipt of further information.. 3.
The inspector stated that during review of the rec.ords being . maintained relative to the Steam Generator Secondary Hydro-static Test, he determined that appropriate details were being omitted.
The licensee stated that the personnel would be instructed to record sufficient details in the documentation.
The inspector stated that one deficiency was identified relative to the calibration of a temperature indicator and no reply is required since the item was corrected prior to the commencement of the Hydro and prior to the conclusion of the ' inspection.

REPORT DETAILS s Persons Contacted
. ~ The following persons, in addition to those listed in the Management Interview section of this report, were contacted during this inspection.
Toledo Edison Company (TECO) L. Kurfis, I&C Foreman { J. Orkins, I&C Engineer J J. Zell, Test Leader ITT Grinnell Company (Crinnell) J. Pomrik, QC Supervisor, Installed Material c 1.
Inappropriate Closure of Nonconformance Report (NCRs) During previous inspection (See Inspection Report No. 050-346/75-03) it was determined that NCRs 376 and 339 were closed even though deficiencies identified in the NCRs were not resolved.
As a result of the inspection findings, NCRs 713 dated June 6, 1975 and NCR 665 dated April 2, 1975, were generated identifying the outstanding deficiencies.
This item remains open.
(-~s \\ \\s_- The inspector reviewed the status.of corrective action taken on the findings of the special in-depth review that was conducted by Stearns-Roger (S-R) relative to NCRs contained in Bechtel QA vault.
To-date about 90% of the inappropriately closed NCRs identified by S-R is reported to be approved and closed by TECO QA.
The inspector was informed that TECO QA has requested S-R to complete a final report based on 88% sampling completed as of May 18, 1976.
The inspector was informed that TECO QA will continue to follow up on corrective action and will complete any open items identified in the above audit program.
The inspector selectively reviewed completed items and determined that items were appropriately resolved.
~ s 2.
Observation of Steam Generator Hydrostatic Test (SCHT) The inspector reviewed TP 200.09, the test procedure for the SGHT and the current revisions and determined that it contained the necessary approvals. The procedure was determined acceptable.

- _ . _ , -"am., - . ' During the inspection, the inspector noticed a temperature , indicator af fixed with expired calibration duc date being used to rN f read the Steam Cencrator Skin temperature.
Further scrutiny, (' indicated the original multi-channel temperature indicator which
was noticed to provide erroncous indications was replaced with a temperature indicator which was only calibrated at three points namely 0, 100 F, and 200 F.
The inspector reminded the licensee of the necessity of using a fully calibrated temperature indicator to assure not exceeding the NDTT.
The inspector informed the licensee that this was a deficiency contrary to the requirements , of 10 CFR 50, Appendix B, Criterion XII.
The licensee corrected the situation and replaced the existing instrument with a calibrated digital temperature indicator prior to reaching a critical pressure < of the Hydro Test.
Instructions to preclude recurrence are to be issued.
The inspector pointed out to the licensee that the QC should have . identified this discrepancy and documented it in a NCR.
Prior to the conclusion of the inspection, a NCR was written documenting the c use of an uncalibrated instrument.
The inspector reviewed.the water chemistry analysis and determined
' that sufficient explanacions were not being documented in cases where the water analysis exceeded the limits specified in Paragraph 5.12.1 TP 200.09.
In one, the water sample from the Steam Generator indicated that the cation conductivity was well over the limit.
The next analysis indicated a considerable drop with no explanation documented.
The inspector was informed that the licensee noticed , ) the high cation conductivity, the situation was analyzed with their d appropriate personnel and was determined to be due to the initial-impurities in the steam generator.
Corrective action was reportedly - taken to repeatedly drain the water till the cation conductivity decreased.
The results of subsequent analysis had been recorded, which indicated a significant drop in the cation conductivity.
The - operation personnel acknowledged the need for complete documentation and informed the inspector that necessary instructions would be
provided to the test personnel.
The licensee's representative stated ' that verbal instructions emphasizing the necessity of complying with I each detail of such procedural and QA requirements have been given to those responsible for this work.
, ' 3.' Review of Documentation on Containment Air Cooling Fans ' During a previous inspection (Inspection Report No. 050-346/75-18), documentation was not available to indicate that the fan motors were tested and determined to satisfactorily operate under the service conditions listed in Paragraph 7.2.2 of Technical Specification 7749-M-400.
During the current inspection, the. inspector reviewed the updating of the incomplete documentation.
It consisted of the Bill of, Material 600 276-17 of Joy Manufacturing, (the fan' supplier)
. , eN . - 6. - - , . f . - --~w - 1--
.. _ to Reliance Electric Company, (the fan motor manufacturer) along . N with Specification No. FF 12642, sheets 1 th. rough 4 which specified ) the design parameters for the radiation environment in whi'ch the y _, motors should operate.
Reliance provided Joy with certificates of conformance that the motors were built to Joy's Bill of ifaterials 600 276-17.
Certificates were provided by Reliance that the air cooler fan motors would operate under the service' conditions ennumerated in Paragraph 7.2.2 of Specification No. 7749-M-400 with no deleterious effects.
The inspector stated that he considered the documentation adequate.
4.
Review of Installed Pipe Hangers Inspections The inspector reviewed the status of the inspections be'ing performed by ITT Grinnell on the installed pipe hangers.
The IE:III inspector was informed that Grinnell QC inspectors walk the line and inspect the installed hanger.co verify whether the installation is in accordance with the respective drawings.
The findings are e documented on the field drawings and are analyzed by Grinnell Engineering for 2-inch and above pipe hangers.
For 2-1v44 and under pipe hangers, the drawings with findings are submitted to Bechtel Engineering for analysis, approvals or corrective action.
As built drawing are generated after corrective action is implemented wherever necessary.
Final inspections are conducted after the completion of field work (where applicable) with final as-built drawings using a 17 point engineered hangers pipe support inspection checklist.
The inspector noted that the actual type of fasteners ('5s ( ) used, such as Red Head Versus Wejit, was being recorded on the drawings.
The inspector reviewed the findings on the following hangers: No. 34-GCB-5-H17 - Decay Heat Removal System No. 33B-GCB-10-H12 - Drain from 8" HBD-263 drain on PSV 319 and PSV'403.
No. 33B-GCB-2-H2 - Drain from 8" HBD-263 drain on PSV 319 and PSV 403.
. ' Typical findings were as follows: , a.
Data point location off.
(Exact dimension was provided)
b.
Clearance was not maintained.
- > c.
All four fastening plates had holes burned.
d.
Cap between plate and wall.
e.
Drawings to be modified to reflect as-builts.
, The IE:III inspector considered the inspection program satisfactory.
