SUMMARY OF FINDINGS
IR 05000247/2008-002; 01/01/2008 - 03/31/2008; Indian Point Nuclear Generating Unit 2;
Maintenance Risk Assessment and Emergent Work Control.
This report covered a three-month period of inspection by resident and region based inspectors.
One finding of very low significance (Green) was identified which was also determined to be a non-cited violation (NCV). The significance of most findings is indicated by their color (Green,
White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, Significance Determination Process. Findings for which the significance determination process (SDP) does not apply may be Green, or be assigned a severity level after NRC management review. The NRCs program for overseeing safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 4, dated December 2006.
NRC-Identified and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
A self-revealing, non-cited violation (NCV) of Title 10 of the Code of Federal Regulations (CFR) Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified for failure to provide an adequate procedure for installing cable termination lugs on the 21 service water pump motor cables. As a result, Entergy maintenance personnel installed undersized terminal lugs for the 21 service water pump motor jumper cables on January 26, 2000, which resulted in a high resistance connection that degraded over time and eventually caused the cables to fail while the pump was in service on January 27, 2008. Entergy entered this issue into the corrective action program, replaced the jumper cables with insulated bus bars, tested the motor for damage, and changed Engineering Standard ENN-EE-S-008-IP, IPEC [Indian Point Energy Center] Electrical Cable Installation Standard, to ensure the use of correctly-sized terminal lugs in the future. Entergy also plans to perform an extent-of-condition review that includes thermography and visual inspections of other safety related motor cable terminations.
The inspectors determined that this finding was more than minor because it was associated with the procedure quality attribute of the Mitigating Systems cornerstone; and, it affected the objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.
Specifically, Entergy failed to provide adequate procedural steps to ensure that the 21 service water pump was installed with appropriate electrical connectors. The inspectors evaluated the significance of this finding using Phase 1 of Inspection Manual Chapter 0609, Appendix A, Determining the Significance of Reactor Inspection Findings for At-Power Situations, and determined that it was of very low safety significance (Green)because it was not a design or qualification deficiency; it did not represent a loss of system safety function of a single train for greater than its Technical Specification allowed outage time; and it did not screen as potentially risk significant due to seismic, flooding, or severe weather initiating events. (Section 1R13)
Licensee-Identified Violations
None.
REPORT DETAILS
Summary of Plant Status
Indian Point Nuclear Generating Unit 2 began the inspection period operating at 100 percent power and remained at or near full power until operators manually tripped the reactor on March 23, 2008, due to lowering steam generator levels as a result of a rapid speed reduction of the 22 main boiler feed pump. Entergy elected to maintain the plant in a shutdown condition to begin the refueling outage (2R18) which had been scheduled to start on March 26,

b. Findings
Introduction:
A self-revealing Green non-cited violation (NCV) of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified because Entergy did not provide an adequate procedure for installing cable termination lugs on the 21 service water pump motor cables on January 26, 2000.
Description:
On January 27, 2008, the 21 service water pump failed while supplying cooling water to the essential service water header. Operators started the 22 service water pump to restore normal cooling to the essential service water header and verified that the 23 service water pump was available to be started if needed. Operators performed these actions because two service water pumps are required during a postulated accident to supply the necessary loads on the essential service water header.
Entergy determined that the cause of the 21 service water pump failure on January 27, 2008, was due to improperly sized cable lugs which resulted in a high resistance connection that caused the B phase cable to fail. On January 26, 2000, the 21 service water pump had been replaced using procedure PVE-B-030-A, Johnson (18EC - 2 Stage) Service Water Pump and Motor Replacement. During the replacement, maintenance personnel determined that the replacement motor leads for two of the three phases were not long enough to reach the existing supply cable terminations. As a result, Entergy changed the maintenance procedure to allow maintenance personnel to fabricate jumper cables to extend the length of the motor cables. The motor leads and the jumper cables were both 1/0 flexible stranded wire (133 strand), which required terminal lugs larger than standard 1/0 American wire gage (AWG) cables (19 strand).
However, the procedure change did not specify the appropriate size lugs for the 1/0 flexible stranded wire, and as a result, standard 1/0 AWG cable termination lugs were installed. The incorrectly sized lugs resulted in an inadequate crimp and a subsequent high-resistance connection that degraded over time, then failed.
Entergy entered this issue into the CAP (CR-IP2-2008-00414), replaced the jumper cables with insulated bus bars, tested the motor for damage, and changed Engineering Standard ENN-EE-S-008-IP, IPEC Electrical Cable Installation Standard, to ensure the use of correctly-sized terminal lugs in the future. Entergy is performing an extent-of-condition review that includes thermography and visual inspections of other safety related motor cable terminations.
Analysis:
The inspectors determined that this issue was a performance deficiency because Entergy failed to specify by procedure the appropriate terminal lugs for the 1/0 flexible stranded wire motor and jumper cables. This finding was reasonably within Entergys ability to foresee and prevent, because the use of standard 1/0 AWG cable termination lugs on 1/0 flexible stranded wire was not an approved method of use.
Traditional enforcement does not apply since there were no actual safety consequences or potential for impacting the NRCs regulatory function, and the finding was not the result of any willful violation of NRC requirements or Entergys procedures.
The inspectors determined that this finding was more than minor because it was associated with the procedure quality attribute of the Mitigating Systems cornerstone; and, it affected the objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.
Specifically, Entergy failed to provide adequate procedural steps to ensure that 21 service water pump was installed with appropriate electrical connectors. The inspectors evaluated the significance of this finding using Inspection Manual Chapter 0609, Appendix A, Determining the Significance of Reactor Inspection Findings for At-Power Situations, and determined that it was of very low safety significance (Green) because it was not a design or qualification deficiency; it did not represent a loss of system safety function of a single train for greater than its Technical Specification allowed outage time; and it did not screen as potentially risk significant due to seismic, flooding, or severe weather initiating events. This finding was determined to not have a cross-cutting aspect since the root problem occurred in the past, and is not indicative of current licensee performance.
Enforcement:
10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, and drawings of a type appropriate to the circumstances. Contrary to the above, on January 26, 2000, Entergy did not provide a maintenance procedure appropriate to the circumstances to ensure safety related maintenance activities were satisfactorily accomplished. Specifically, the service water motor replacement procedure did not specify the appropriate size cable termination lug for the service water motor cable. The installation of undersized terminal lugs on January 26, 2000, for the 21 service water pump resulted in a high resistance connection that degraded over time and eventually caused the cables to fail while the pump was in service on January 27, 2008. Entergy entered this issue into their corrective action program (CR IP2-2008-00414), replaced the jumper cables with insulated bus bars, tested the motor for damage, and changed Engineering Standard ENN-EE-S-008-IP, IPEC Electrical Cable Installation Standard, to ensure the use of correctly-sized terminal lugs in the future. Entergy is performing an extent-of-condition review that includes thermography and visual inspections of other safety related motor cable terminations. Because this finding is of very low safety significance and has been entered into the corrective action program, this violation is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy. (NCV 05000247/2008002-01)
1R15 Operability Evaluations

The inspectors conducted a review of the effectiveness of corrective actions associated with the June 2005 NRC finding that identified Entergys inadequate testing of the temporary technical support center diesel generator (05000247/2005008-01). The inspectors interviewed personnel responsible for implementing the procedures, reviewed condition reports associated with the finding and documented corrective actions and assessed Entergys threshold for problem identification, the adequacy of the analysis, and extent of condition review. The documents reviewed during the inspection are listed in the Attachment.
b. Findings and Observations
No findings of significance were identified.
The inspectors observed that Entergy appropriately addressed the causes and extent of condition for the finding. Corrective actions for the issue and associated causes were adequate.
4OA3 Event Follow-up
.1 Manual Reactor Trip on March 23, 2008, Due to Lowering Steam Generator Levels as a
Result of 22 Main Boiler Feed Pump Runback
a. Inspection Scope
The inspectors observed control room personnel response to an unexpected manual reactor trip on March 23, 2008, that resulted from lowering steam generator levels caused by a speed runback (lowering) of 22 main boiler feed pump. The inspectors observed Entergys post-trip response in the control room to verify that plant equipment response was as expected, and to ensure that operating procedures were being appropriately implemented. The inspectors attended post-trip review and forced outage meetings, and discussed the event and corrective actions with plant management. The cause of the main boiler feed pump runback was not determined by the end of the inspection period. Instead of commencing restart activities, Entergy elected to begin a normal plant cooldown and start the 2R18 refueling outage. The 2R18 outage was originally scheduled to begin on March 26, 2008. The documents reviewed are listed in the Attachment.
b. Findings
No findings of significance were identified.
