Attachment '. to PLA"546 CABLE DAMAGE SUSTAINED DURING PULLING OPERATIONS On June 15,
- 1979, MCAR 1-35 reported that severe cable damage resulted from pulling cable through conduit at Susquehanna SES Unit 1.
The concern expressed in the MCAR was whether all damaged cables will be identified by megger tests when the suspect cables are routed through PVC conduit in which ground conductors are not required for the cable installation. The MCAR indicated that cable damage was detected by "visual inspec-tion of the cable jacket or by megger tests" during normal QC inspection activities and cable pulling operations, and was documented on Non-Conformance Reports (NCR's) attached to the MCAR. As indicated in the NCR's, the cable damage includes: cable with cut/ tom outer jacket, cut/tom conductor insulation and/or broken conductor standing. It also includes cable which failed the megger tests. Cause: Based on several investigations made at the jobsite during the week of June 18,
- 1979, and subsequently, and a review of the relevant NCR's, it has been determined that the cable damage resulted from one or a combination of the factors listed below:
1. Too many bends between pull points. 2. Too small bending radius some 90 elbows. 3. Lack of adequate as-built data on which calculations could be based. The type of cable pulling compounds used. 5. Use of two conductor "flat" cable (Type D12). 6. Mixing of large and small diameter cables in the same conduit. 7. Combining cables of differing length and destination in the same conduit. 8. Use of small diameter single conductor cable in long and complex raceway installations (particularly Type Dll). Anal sis of Safety Im lications: The reported cable damage was found during cable pulling operations and QC inspection activities. The damage was documented on Non-Conformance Reports (NCR's) per Bechtel procedures.
A revie~ of NCR's identified by the Field, and issued between ll/14/78 and 6/6/80, indicates the following: 1. PP&L has considered two (2) categories of Class lE cable damage from the NCR's identified as being reportable under 10CFR50.55(e). These categories are addressed in detail in Tables I and II (Attachments 2 and 3 to this report). and are summarized below: a) Table I lists the NCR's which reported the cables that failed the megger tests. o Total scheme cables listed in Table I..................49 o Number of scheme cables dispositioned to reject and rework.............................................40 o Number of cables dispositioned to be acceptable.........7 o Number of cables with no damage detected and have since passed a megger test..............................2 Of the 40 scheme cables rejected, 26 were type Dll. b) Table II lists the NCR's which reported the cables that were damaged during pulling. o Total of scheme cables listed in Table II..............65 o Number of scheme cables dispositioned to reject and rework......................................43 o Number of cables dispositioned to be acceptable.............................................22 Seven of the 43 rejected cables were type Dll which failed the megger test. 2. Tables I and II (Paragraph 1-a and 1-b above) indicate that there were 114 scheme cables reported in the NCR's. NCR disposition indicates that 29 of these cables have been verified to be acceptable. In addition, there were 2 cables which have passed the megger tests with no damage detected. These cables were dispositioned for a re-megger test at a higher value (see NCR-5424). The remaining 83 cables were dispositioned to reject and rework. 3. Approximately one half of the damaged scheme cables were detected visually with the remaining ones discovered through megger tests and rejected. 4. Of the 83 damaged scheme cables rejected, approximately 80% occurred on 600 V Power and Control Cable, f!2AViG and smaller, manufactured by AIM Corporation. 5. The nature of the cable damage was varied, and the cause of the damage could not be attributed to one single factor. 6. Raychem is the only supplier of cable that 'did not exhibit cable damage or overtensioning. 7. Based on the May, 1980 circuit schedule, more than 4,800 safety-related scheme cables are shown as pulled.
The data above indicates that the rate of 1/C 810 megger test failure is higher than for the other cable types. Review of documents indicates that this is the smallest and weakest cable used in the SSES Project. It also indicates that this cable is one of the cables most commonly used in both the 480 V and 120 V power and control cabling system.
- Hence, this cable is the most susceptible to damage, especially in long, complex raceway system.
To prevent and/or minimize this type of cable damage in the future, steps have been taken as reported in the next section. Low voltage megger tests are performed on all power cables to locate direct short-circuits and to facilitate the pre-operational, functional testing and startup procedures. NPE has determined the cable damage identified in this NCAR 1-35 to be reportable under 10 CFR 50.55(e). Corrective Action: The adequacy of the project cabling system will have been assured when all integrated startup procedures, including pre-operational and functional testing planned and scheduled for the future, are successfully completed. During the construction phase of a project, the servicibility of the installed (pulled) cables can be achieved by compliance with the following procedures, which are in Field Procedure FP-E-5: 1. Visual inspection of raceways to ensure the removal of burrs and other foreign material that may be damaging to the cable (Field Procedure FP-E-5, Paragraph 7.1.5 and 7.1.6), 2. Cable pulling operation monitoring to assure proper rigging,
- handling, and application of pulling compound to the cable
~ (Field Procedure FP-E-5, Part II, Paragraph 7.7.7 and 7.1.24). 3. Verification of adequate data used for the determination of maximum allowable tensile stress and sidewall pressure (FP-E-5, Part II, Paragraph
- 7. l. 7).
4. Tensiometer monitoring on machine 'pulls to verify that the maximum allowable tensile stress and sidewall pressure are not exceeded (FP-E-5, Part II, Paragraph 7.1.25). 5. Visual inspection of the cable that has emerged from the race-way at the pulling end for indications of cable damage (FP-E-5, Part II, Paragraph 7.1.25). 6. iMegger testing of 600 V and higher power, cable (9 to 9 and 9 ground) to detect any obvious short circuits that may be present (FP-E-5, Part II, Paragraph 7.1.25). When the cable over-tensioning condition was first reported by the field, Project Engineering determined that several options were available for the resolution of the problem, and evaluated each one of these options on an individual basis*. It was determined that the most viable option was to have the cable manufacturers justify and permit the use of an increased
maximum allowable tension value. To accomplish this, and at the advice of the cable manufacturer, a cable test plan was implemented at the jobsite. This would enable the cable manufacturers to provide justification for the increased maximum allowable tension values. Upon completion of the tension tests, the tested cables were sub-jected to a series of physical and electrical tests by the respective cable manufacturers. Based on the results of these tests, the manufacturers revised their data previously submitted and increased the maximum allowable pulling tensions for their cables. Accordingly, these increased allowable tensions were incorporated into Drawing E-59. (

- 1979, Document Control Number 103968 and AIW Reports, Vendor Document Number 8856-E-130-A166(1)-1 dated 2/7/80 and -166(2)-1 dated 2/5/80).
Based on the revised values of maximum allowable pulling tensions, the Field has implemented Appendix B of the interim Response to this
- HCAR, which outlined the procedures for the verification of cables installed prior to the June 14, 1979 work stoppage.
As a result of the verification program, the Field reported that there was no new Class 1E cables identified to be overtensioned. Fo'r Unit 1 and Common, Project Engineering has reviewed the use of small single conductor cable and two conductor "flat" cable for pulls yet to be made. Where deemed appropriate, consi'dering the complexity of the pull and raceway percent fill, such cables are being replaced with either a larger size conductor or a round multiconductor cable to facilitate'cable pulling. En addition, two conduct'or round cables have been added to the Purchase order. These cables are intended for limited use on difficult pulls. This procedure is also implemented for Unit 2. Project Engineering has begun a review of the more complex conduit networks for Unit 2 and, where appropriate, will modify the raceway design to facilitate cable pulling. Appropriate action has been taken by the Field to ensure that procedures established for, the cable pulling operations are followed for every cable pull. (See Bechtel Construction letter to PP&L Construction BCLPC-6374 dated July 12, 1979). The Field will continue to monitor every cable pull and document any cable damage and overtensioning. A sampling plan for meggering of multi-conductor control cable of flat-configurat'on and single conductor control cable !P8 and smaller has been aporoved by PP&L as per PCLBC-3181 dated 12/6/79 (Document Control Number 114820). The sampling plan, which covers both the installed control cables and future control cable'nstallation, has been implemented by the Field. As a result of this program, the Field reported in BCLPC-7743 dated 5/21/80 (Document Control Number 119795) to PP&L Construction that no failures were found on the sampling of Class 1E cables installed prior to the stop work date. En addition, a testing program has been implemented to test all Dll
(1/C f10 AWG) cable presently installed 9 Susquehanna SES. It consists of a DC megger at voltages up to 5 KV DC on all Q as well as non+ cable. The acceptance criteria will be 1000 megohm minimum resistance. All cable which fails thi.s criteria will be tagged for replacement or abandonment.
== Conclusions:== 1. Some safety-related cables were damaged during normal scheduled cable pulling activities. This damage was discovered and documented on NCRs during QC inspections. 2. The cause of the cable damage was one or more of the factors 1'sted under "Causes". The nature of the cable damage was varied, and was described in the referenced NCR's. Where overtension had originally been identified as a deficiency, new analyses by cable manufacturers showed that the original maximum sidewall pressures were conservative; therefore, .these original over-tension deficiencies, when rechecked, were all found to be acceptable under the revised maximum pulling tensions. 3. The mixing of large and small diameter cables in the same raceway and the use of 2/c cable in a flat configuration on both long and/or complex pulls will be avoided, wherever possible, in the Euture as a result of the corrective measures being implemented by both Project Engineering and Construc-tion. 4. Megger testing is in the construction procedures and will continue to be employed in the Euture. 5. As cable damage was discovered, it was documented through the QA Program. 6. The Fi'eld completed the implementation of Appendix B of the Interim
Response
to this MCAR, which outlined the procedures for the verification of cables installed prior to June 14, 1979 work stoppage. Based on the revised values of maximum allowable pulling tensions shown in Drawing E-59, the Field reported that there was no new Class lE cables identified to be overtensioned. 7. The project Field QC has been monitoring the Construction activities to ensure that procedures established Eor the installation of cables are followed. 8. Through the action taken and the testing programs implemented as outlined in the section entitled "Corrective Action", NPE believes the cable pulling problems have been satisfactorily resolved.
