This report documents seven findings of very low safety significance (Green). | INSPECTION REPORT 05000247/2009002 | ||
should provide a written response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington D.C. 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Senior Resident Inspector at Indian Point Nuclear Generating Unit 2. | Dear Mr. Pollock: | ||
On March 31, 2009, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection | |||
at Indian Point Nuclear Generating Unit 2. The enclosed integrated inspection report | |||
documents the inspection results, which were discussed on April 15, 2009, with you and other | |||
members of your staff. | |||
The inspection examined activities conducted under your license as they relate to safety and | |||
compliance with the Commissions rules and regulations, and with the conditions of your | |||
license. The inspectors reviewed selected procedures and records, observed activities, and | |||
interviewed personnel. | |||
This report documents seven findings of very low safety significance (Green). Six of these | |||
findings were also determined to be violations of NRC requirements. However, because of their | |||
very low safety significance, and because the findings were entered into your corrective action | |||
program, the NRC is treating these findings as non-cited violations (NCVs) consistent with | |||
Section VI.A.1 of the NRC Enforcement Policy. If you contest any NCV in this report, you | |||
should provide a written response within 30 days of the date of this inspection report, with the | |||
basis for your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control Desk, | |||
Washington D.C. 20555-0001; with copies to the Regional Administrator, Region I; the Director, | |||
Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC | |||
20555-0001; and the NRC Senior Resident Inspector at Indian Point Nuclear Generating Unit 2. | |||
In addition, if you disagree with the characterization of any finding, you should provide a | |||
response within 30 days of the date of this inspection report, with the basis for your | |||
disagreement, to the Regional Administrator and the NRC Resident Inspectors at Indian Point | |||
Nuclear Generating Unit 2. The information you provide will be considered in accordance with | |||
Inspection Manual Chapter 0305. | |||

SUMMARY OF FINDINGS | |||
IR 05000247/2009-002; 01/01/2009 - 03/31/2009; Indian Point Nuclear Generating (Indian | |||
the | Point) Unit 2; Adverse Weather Protection; Fire Protection; Maintenance Effectiveness; | ||
Maintenance Risk Assessments; Surveillance Testing; and Radiological Access Control. | |||
This report covered a three-month period of inspection by resident and region based inspectors. | |||
Seven findings of very low significance (Green) were identified, six of which were also | |||
determined to be non-cited violations (NCV). The significance of most findings is indicated by | |||
their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, | |||
Significance Determination Process. The cross-cutting aspect for each finding was | |||
determined using IMC 0305, Operating Reactor Assessment Program. 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. | |||
A. NRC-Identified and Self-Revealing Findings | |||
Cornerstone: Initiating Events | |||
* Green. The inspectors identified a NCV of very low safety significance related to 10 CFR | |||
50, Appendix B, Criterion XVI, Corrective Actions, because Entergy did not promptly | |||
identify and correct an adverse condition related to an electrical fault. Specifically, | |||
personnel did not identify a safety-related cubicle had experienced an electrical fault | |||
prior to replacement of upstream fuses and restoration of power to the damaged cubicle. | |||
Entergy entered the issue into the corrective action program as IP2-2009-00342 and | |||
IP2-2009-00483, trained all operations personnel on the requirements to replace fuses | |||
and re-energize electrical equipment, and plans to revise the operations procedure for | |||
operating electrical equipment. | |||
This issue was more than minor because the finding was associated with the external | |||
factors attribute of the Initiating Events cornerstone and impacted the cornerstone | |||
objective of limiting the likelihood of those events that upset plant stability and challenge | |||
critical safety systems during shutdown as well as power operations. The inspectors | |||
determined that the issue increased the likelihood of a fire in the emergency diesel | |||
generator (EDG) building. The condition was evaluated by a Senior Reactor Analyst | |||
utilizing Phase 2 of IMC 0609 Appendix F, Fire Protection Significance Determination | |||
Process. It was determined that in the event of a fire consuming the MCC, no transient | |||
would be placed on the plant and no components required to safely shutdown the plant | |||
would be impacted. As a result, in accordance with task 2.3.5 of Appendix F, the issue | |||
was screened to Green. | |||
The inspectors determined that a cross-cutting aspect was associated with this finding | |||
in the area of human performance related to conservative decision making. Specifically, | |||
Entergys decision-making was non-conservative related to its decisions on the process | |||
used to identify the source of the acrid odor; re-energize the damaged electrical | |||
equipment; and keep a damaged electrical component energized for 14 days prior to its | |||
removal from the MCC. [H.1(b) per IMC 0305] (Section 1R05) | |||
Enclosure | |||
4 | |||
* Green. The inspectors identified a NCV of very low safety significance related to TS | |||
5.4.1, Administrative Controls: Procedures, because Entergy did not maintain an | |||
adequate maintenance procedure for a safety-related electrical motor control center | |||
(MCC). Specifically, the eight-year maintenance procedure for the affected EDG | |||
ventilation MCC did not contain an adequate method to identify high resistance | |||
connections within the cubicle as was expected in the applicable preventative | |||
maintenance industry template. Subsequently, a high resistance connection within the | |||
MCC developed into a phase-to-phase electrical fault on January 28, 2009. Entergy | |||
entered the issue into the corrective action program, scoped the affected MCC and 21 | |||
additional MCCs into the sites thermography program, and planned to revise the | |||
maintenance procedure. | |||
This issue was more than minor because the finding was associated with the external | |||
factors attribute of the Initiating Events cornerstone and impacted the cornerstone | |||
objective of limiting the likelihood of those events that upset plant stability and challenge | |||
critical safety systems during shutdown as well as power operations. Specifically, the | |||
high resistance connection degraded into a phase-to-phase fault and increased the | |||
likelihood of a fire in the EDG building. The condition was evaluated by a Senior | |||
Reactor Analyst utilizing Phase 2 of IMC 0609 Appendix F, Fire Protection Significance | |||
Determination Process. It was determined that in the event of a fire consuming the | |||
MCC, no transient would be placed on the plant and no components required to safely | |||
shutdown the plant would be impacted. As a result, in accordance with task 2.3.5 of | |||
Appendix F, the issue was screened to Green. | |||
The inspectors determined that the finding had a cross-cutting aspect associated with | |||
the area of problem identification and resolution related to the use of operating | |||
experience (OE). Specifically, Entergy personnel did not implement industry | |||
recommended practices, or an alternate equivalent method, for identifying high | |||
resistance connections in electrical switchgear. [P.2(b) per IMC 0305] (Section 1R12) | |||
Cornerstone: Mitigating Systems | |||
* Green. The inspectors identified a finding of very low safety significance because | |||
Entergy personnel did not adequately implement procedure EN-LI-102, Corrective Action | |||
Process, and promptly identify a condition adverse to quality associated with open | |||
louvers in a fire protection pump room following pump testing on January 14, 2009. The | |||
open louvers resulted in freezing conditions in fire protection piping located in the room | |||
and cracked two six-inch header isolation valves on January 17, 2009. Entergy entered | |||
the issue into the corrective action program and performed a site-wide extent-of- | |||
condition walkdown of louvers. | |||
The finding was more than minor because it was associated with the protection against | |||
external factors attribute of the Mitigating Systems cornerstone and it affected the | |||
cornerstone objective of ensuring the reliability of systems that respond to initiating | |||
events to prevent undesirable consequences. This finding was evaluated using Phase | |||
1 of IMC 0609 Appendix F, Fire Protection Significance Determination Process. The | |||
inspectors determined the issue was of very low safety significance (Green) because | |||
the cracked valves were easily isolated and did not pass sufficient water to render the | |||
fire header non-functional (low degradation rating). | |||
Enclosure | |||

Specifically, Entergy personnel that routinely tour the 11 fire pump house did not | |||
specifically listed in Table 2 of the plant specific Phase 2 SDP risk-informed inspection notebook. | question the abnormally cold room temperatures. [H.4(a) per IMC 0305] (Section 1R01) | ||
* Green. The inspectors identified a NCV of very low safety significance related to License | |||
The inspectors determined that the finding had a cross-cutting aspect in the area of human performance related to work control. | Condition 2.K., fire protection program, because personnel did not promptly identify and | ||
correct a degraded three-hour rated fire door latch mechanism on the west entrance of | |||
the 480-Volt switchgear room. Specifically, inspectors identified the fire door in a non- | |||
functional state on several instances over the course of a month. Entergy personnel | |||
replaced the fire door latch mechanism on March 3, 2009. This issue was entered into | |||
the corrective action program as six condition reports spanning several weeks and | |||
included an extent of condition walkdown of site fire doors. | |||
The finding was more than minor because it is associated with the protection against | |||
external factors attribute of the Mitigating Systems cornerstone and affected the | |||
cornerstone objective of ensuring the reliability of systems that respond to initiating | |||
events to prevent undesirable consequences. This fire door, when degraded, impacts | |||
the reliability of mitigating systems in the 480-Volt switchgear room that are relied upon | |||
during a postulated large fire in the turbine building, and vice versa. This finding was | |||
evaluated using Phase 1 of IMC 0609 Appendix F, Fire Protection Significance | |||
Determination Process. Since the area in question had a fire watch posted during the | |||
time the door was degraded for an unrelated issue, an adequate level of protection was | |||
maintained to compensate for the degraded door. As such, according to task 1.3.1, the | |||
inspectors determined the finding was Green. | |||
The inspectors determined that the finding had a cross-cutting aspect in the area of | |||
problem identification and resolution because Entergy personnel did not thoroughly | |||
evaluate a degraded fire door latch on several occasions, such that the resolution of the | |||
problems addressed the causes. [P.1(c) per IMC 0305] (Section 1R05) | |||
* Green. The inspectors identified a NCV of very low safety significance related to 10 CFR | |||
50.65(a)(4), because Entergy personnel did not adequately assess the risk associated | |||
with the unavailability of the Refueling Water Storage Tank (RWST) level indication | |||
during planned maintenance on the level transmitters and instrumentation. Entergy | |||
entered the issue into the corrective action program (CR-IP2-2009-00342), updated the | |||
risk model to include the maintenance activity, assessed the risk, and appropriately | |||
coded the maintenance activity to ensure it would be risk assessed in the future. | |||
The inspectors determined that this finding was more than minor because it was a | |||
maintenance risk assessment issue in which personnel did not consider risk significant | |||
SSCs that were unavailable during maintenance. The RWST level indication is | |||
specifically listed in Table 2 of the plant specific Phase 2 SDP risk-informed inspection | |||
notebook. The inspectors determined the significance of this issue in accordance with | |||
IMC 0609, Appendix K, Maintenance Risk Assessment and Risk Management | |||
Significance Determination Process. The inspectors determined that this finding was of | |||
very low safety significance because the Incremental Core Damage Probability Deficit | |||
was less than 1E-6. | |||
The inspectors determined that the finding had a cross-cutting aspect in the area of | |||
human performance related to work control. Specifically, Entergy personnel did not | |||
Enclosure | |||

[H.4(b) per IMC 0305] (Section 2OS1) | appropriately plan work activities by incorporating risk insights for affected plant | ||
equipment. [H.3(a) per IMC 0305] (Section 1R13) | |||
None. | * Green. The inspectors identified a NCV of very low safety significance related to 10 | ||
8 | CFR 50.55a, Codes and standards, because Entergys procedure, 2-PT-Q031A for an | ||
auxiliary component cooling water pump, did not contain appropriate acceptance criteria | |||
for positively determining that safety-related check valves performed their safety function | |||
power and remained at or near full power during the quarter. | when required in accordance with the American Society of Mechanical Engineers | ||
(ASME) OM Code. Specifically, the test used reverse rotation of a parallel pump to | |||
verify that the pumps discharge check valve was closed although previous site-specific | |||
experience demonstrated that the pump impeller would not rotate backwards when the | |||
1R01 Adverse Weather Protection (71111.01 - 1 sample) | check valve was stuck open. Entergy entered this issue into their corrective action | ||
program as CR-2009-1312. | |||
The inspectors determined that the performance deficiency was greater than minor | |||
because it was associated with the procedure quality attribute of the Mitigating System | |||

of systems that respond to initiating events to prevent undesirable consequences. | |||
The inspectors also reviewed | Specifically, the test criterion used in procedure 2-PT-Q013A did not ensure that valve | ||
b. Findings | 755A reliably performed its safety function when tested as demonstrated by testing | ||
performed in January 2005. The inspectors determined that the performance deficiency | |||
was of very low safety significance (Green) IMC 0609, Attachment 4, Phase 1 - Initial | |||
Screening and Characterization of Findings. Specifically, the inspectors determined | |||
that this finding was of very low safety significance because the finding did not result in | |||
a loss of safety function and did not screen as potentially risk-significant due to external | |||
events initiating events. | |||
The inspectors determined the finding had a cross-cutting aspect related to effective | |||
corrective actions in the corrective action program component of the problem | |||
identification and resolution area. Specifically, Entergy personnel did not implement | |||
effective corrective actions to resolve the testing inadequacy since 2005 and during | |||
subsequent quarterly testing. [P.1(d) per IMC 0305] (Section 1R22) | |||
Cornerstone: Occupational Radiation Safety | |||
* Green. The inspectors identified a NCV of very low safety significance related to | |||
Technical Specification 5.4.1.a, Procedures, because Entergy personnel did not | |||
generate condition reports or investigation paperwork for multiple high dose-rate alarms | |||
as required by station procedures. Specifically, personnel did not generate the required | |||
condition reports and adequately document the investigations for six instances of | |||
unplanned or un-briefed electronic dosimeter alarms that occurred between January | |||
2009 and March 2009. The performance deficiency resulted in workers receiving | |||
unanticipated dose rate alarms with no formally-documented investigation prior to | |||
returning to work in a Radiologically Controlled Area. Entergy entered the finding into | |||
the corrective action program as condition report CR-IP3-2009-01253 and 01318. | |||
The finding is more than minor because it is associated with the Occupational Radiation | |||
Safety cornerstone attribute of programs and process, and adversely affected the | |||
objective to ensure adequate protection of worker health and safety from exposure to | |||
radiation. Moreover, the inspectors identified a programmatic deficiency to maintain and | |||
implement programs to keep exposures as low as reasonably achievable, because | |||
Enclosure | |||
7 | |||
multiple examples were identified regarding the failure to satisfy station radiation | |||
protection procedures. Using the Occupational Radiation Safety Significance | |||
Determination Process, the inspectors determined that the finding was of very low safety | |||
significance (Green) because it did not involve: (1) as low as is reasonably achievable | |||
planning and controls, (2) an overexposure of an individual, (3) a substantial potential for | |||
overexposure, or (4) an impaired ability to assess dose. | |||
The inspectors determined that the finding had a cross-cutting aspect related to | |||
procedural adherence in the work practices component of the human performance area. | |||
Specifically, Entergy personnel did not follow procedures to generate condition reports | |||
and document investigations when high dose-rate alarms were received by workers. | |||

a. Inspection Scope | |||
The inspectors reviewed the overall preparations and protection of risk-significant | |||
systems for extremely cold weather conditions from January 14 - 19, 2009. The | |||
inspectors reviewed and assessed implementation of the sites adverse weather | |||
preparation procedures and compensatory measures for the affected conditions before | |||
the onset of and during the cold weather conditions. This included verification that | |||
operator actions defined in their adverse weather procedure maintain readiness of | |||
essential systems that are vulnerable to freezing temperatures. The inspectors verified | |||
Entergy personnel implemented periodic equipment walkdowns or other measures to | |||
ensure the condition of plant equipment was operable. | |||
The inspectors also reviewed Entergys corrective action program to review previous | |||
issues associated with cold weather preparations and freezing conditions. Documents | |||
reviewed are listed in the attachment. | |||
b. Findings | |||
Introduction. The inspectors identified a Green finding because Entergy personnel did | |||
not adequately implement procedure EN-LI-102, Corrective Action Process, and | |||
promptly identify a condition adverse to quality associated with stuck-open louvers in a | |||
fire protection pump room following pump testing on January 14, 2009. | |||
Description. On January 17, 2009, during a period of sustained cold weather which | |||
included sub-zero temperatures, control room personnel received a fire panel trouble | |||
alarm indicative of a low-pressure condition in the fire header and dispatched a plant | |||
operator to investigate. The operator identified spraying water from the body of a | |||
ruptured six-inch fire protection valve located in the 11 fire pump house. The operator | |||
isolated the broken valve from the fire header by shutting a manually-operated upstream | |||
valve which stopped the water spray. In addition, the operator observed that the pump | |||
house room was significantly colder than expected and subsequently identified the | |||
rooms ventilation louvers to the outside were mechanically bound in the open position. | |||
The operator disconnected the louver linkage and manually shut the louvers. | |||
Enclosure | |||
9 | |||
On January 21, 2009, the inspectors identified a second six inch valve that was cracked | |||
due to the previous cold weather (freezing) conditions in the fire pump house. Entergy | |||
personnel entered this issue into the corrective action program and performed site | |||
walkdowns to identify additional adverse conditions associated with the cold weather. | |||
The inspectors determined that Entergy did not fully implement Entergy procedure EN- | |||
LI-102, Corrective Action Process. Specifically, EN-LI-102 requires plant personnel to | |||
identify adverse conditions, including cold-weather related conditions, and then enter | |||
them into the CAP for resolution. Attachment 9.2 of the procedure provides examples of | |||
adverse conditions expected to be reported; Section 1 of the Attachment contains | |||
examples of operational conditions requiring entry into the CAP including "events or | |||
conditions that could negatively impact reliability or availability." Additionally, plant | |||
operators should have had heightened awareness to cold weather conditions because | |||
Entergy procedure OAP-008, "Severe Weather Preparations," requires in step 4.3.7, | |||
when freezing conditions are expected, that increased monitoring of plant areas to | |||
monitor for adverse effects on plant equipment and verify that adequate protection is | |||
provided. Operations personnel did not identify abnormal conditions in the 11 fire pump | |||
room that led to the freezing and subsequent rupture of fire protection components. | |||
The inspectors determined it was reasonable for Entergy personnel to identify this issue | |||
because operators should have identified that the louvers failed to shut following a | |||
routine operations test of 11 fire pump on January 14, 2009. In addition, operators | |||
perform tours of the pump house every 12 hours and should have identified the room | |||
was much colder than normal. | |||
Analysis. The inspectors identified a performance deficiency because Entergy | |||
personnel did not implement procedure guidance and identify stuck open louvers and a | |||
subsequent second cracked fire header valve in the 11 fire pump house. The finding | |||
was more than minor because it was associated with the protection against external | |||
factors attribute of the Mitigating Systems cornerstone and it affected the cornerstone | |||
objective of ensuring the reliability of systems that respond to initiating events to prevent | |||
undesirable consequences. Specifically, the failure of the six-inch valves impacted the | |||
reliability of the fire header until the ruptured valve was isolated. | |||
This finding was evaluated using Phase 1 of Inspection Manual Chapter (IMC) 0609 | |||
Appendix F, Fire Protection Significance Determination Process. The inspectors | |||
determined the issue was of very low safety significance (Green) because the cracked | |||
fire valves were easily isolated and did not pass sufficient water to render the fire | |||
header non-functional. Specifically, the inspectors assigned a low degradation rating to | |||
the fire header because the fire pumps were able to maintain pressure in the fire header | |||
until the ruptured valves were isolated. | |||
The inspectors determined that the finding had a cross-cutting aspect in the area of | |||
human performance related to work practices - human error prevention techniques. | |||
Specifically, Entergy personnel routinely tour the 11 fire pump house did not question | |||
the abnormally cold room temperatures. (H.4(a) per IMC 0305) | |||
Enforcement: Enforcement action does not apply because the performance deficiency | |||
did not involve a violation of a regulatory requirement. Because this finding does not | |||
involve a violation of regulatory requirements and has very low safety significance, it is | |||
identified as FIN 05000247/2009002-01, Failure to Identify Open Louvers in 11 Fire | |||
Pump House. | |||

The inspectors performed partial system walkdowns to verify the operability of redundant | |||
or diverse trains and components during periods of system train unavailability, or | |||
following periods of maintenance. The inspectors referenced the system procedures, | |||
the UFSAR, and system drawings to verify the alignment of the available train supported | |||
its required safety functions. The inspectors also reviewed applicable condition reports | |||
(CR) and work orders to ensure Entergy personnel identified and properly addressed | |||
equipment discrepancies that could potentially impair the capability of the available train, | |||
as required by Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix | |||

.1 Failure to Identify Damaged Components in EDG Ventilation Motor Control Center | |||
Introduction: The inspectors identified a NCV of very low safety significance (Green) | |||
related to 10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, because Entergy | |||
personnel did not promptly identify and correct an adverse condition related to an | |||
electrical fault. Specifically, personnel did not identify a safety-related cubicle (bucket) | |||
had experienced a fault prior to replacement of upstream fuses and restoration of power | |||
to the cubicle. | |||
Description: On January 28, 2009, operations personnel detected an acrid odor coming | |||
from the emergency diesel generator (EDG) building. Operators entered the EDG | |||
building to investigate the source of the acrid odor and identified that a MCC was de- | |||
energized. Operations personnel did not identify external damage to the MCC; however, | |||
operators did not open MCC panels to inspect for internal damage. Operators checked | |||
the upstream 175 amp supply fuses, located in a different building, and identified that 2 | |||
of 3 fuses had blown. Operators opened the downstream breakers on the MCC in the | |||
EDG building and then replaced the 175 amp supply fuses in the control building. Once | |||
operators replaced the blown fuses, they re-energized the EDG building MCC#1, and | |||
subsequently began to locally shut all of the cubicle switches. When operators | |||
attempted to shut the switch associated with cubicle 4N, the switch did not function as | |||
expected. Operators then opened the panel for cubicle 4N and identified charred | |||
electrical components. | |||
Entergy personnel generated a D level condition report (CR) for cubicle 4N on the | |||
basis that it supplies a non safety-related (NSR) EDG room heater. Entergy personnel | |||
closed the CR to a work request to troubleshoot and repair the NSR heater. However, | |||
the inspectors questioned the classification of the MCC and determined that the charred | |||
components were safety related (SR). Cubicle 4N contains a SR main line switch and | |||
SR 30 amp main line fuses. The 30 amp fuses are SR to isolate the NSR heaters from | |||
the MCC in the event of a room heater fault. The inspectors also questioned the | |||
appropriateness of leaving the damaged cubicle in the energized MCC. Following | |||
inspector questions, Entergy staff issued another CR and removed the damaged cubicle | |||
from the MCC on February 11. During removal of the charred cubicle, maintenance | |||
personnel were unable to disconnect the main line cables due to arc-welding at the | |||
termination and subsequently had to cut two of the three cables upstream of the | |||
termination and cubicle switch. These cables and the line side of the switch were | |||
energized from January 28 until February 11. After the damaged cubicle was removed, | |||
engineering personnel performed an inspection and determined that the fault originated | |||
from a high resistance connection on the C phase between the main fuse clip and the | |||
cubicle supply switch in the 4N cubicle. | |||
The inspectors determined that replacing the upstream 175 Amp fuses on and restoring | |||
power to the EDG ventilation MCC #1, which contained the charred 4N cubicle, without | |||
identifying the source of the acrid odor could have reinitiated the fault and increased the | |||
probability of a fire. In addition, operations personnel tried to locally close the damaged | |||
switch which could have also re-initiated the fault. Entergy staff also did not take action | |||
to remove or de-energize the charred cubicle after the condition was identified on | |||
January 28, 2009. The damaged cubicle was de-energized and removed from the MCC | |||
on February 11 in response to the inspectors questions. | |||
Enclosure | |||
12 | |||
This issue was reasonable for the licensee to foresee and correct because acrid odor is | |||
an indication of a fault. It was reasonable for Entergy personnel to open panel doors | |||
and perform visual inspections of the affected MCC prior to replacing upstream fuses | |||
and restoring power to the fault. The inspectors determined that the National Electrical | |||
Code NFPA 70E, Standard for Electrical Safety in the Workplace, prohibits | |||
reenergizing a circuit after a protective device has operated until it has been determined | |||
that the automatic operation was a result of an overload and not a fault. The acrid odor | |||
in the EDG building was an indication of a fault vice an overload condition. In addition, | |||
once Entergy personnel identified the cubicle was charred and experienced an electrical | |||
fault, industry standards would have operators immediately secure power and/or | |||
remove the damaged gear from the MCC. | |||
Entergy entered the issue into the corrective action program as IP2-2009-00342 and | |||
IP2-2009-00483, trained all operations personnel on the requirements to replace fuses | |||
and re-energize electrical equipment, and plans to review operations procedures for | |||
EDG building | operating electrical equipment. | ||
electrical components | Analysis: The inspectors determined that Entergys failure to promptly identify an | ||
adverse condition associated with damaged electrical components constituted a | |||
performance deficiency. This issue was more than minor because the finding was | |||
associated with the external factors attribute of the Initiating Events cornerstone and | |||
impacted the cornerstone objective of limiting the likelihood of those events that upset | |||
plant stability and challenge critical safety systems during shutdown as well as power | |||
operations. Specifically, operations personnel did not identify the source of the acrid | |||
odor, indicative of an electrical fault, in the EDG building; re-energized damaged | |||
electrical equipment; and left damaged electrical components (cubicle 4N) energized for | |||
14 days prior to its removal from the MCC. The inspectors determined these issues | |||
increased the likelihood of a fire in the EDG building. The condition was evaluated by a | |||
Senior Reactor Analyst utilizing Phase 2 of IMC 0609 Appendix F, Fire Protection | |||
Significance Determination Process. It was determined that in the event of a fire | |||
consuming the MCC, no transient would be placed on the plant and no components | |||
required to safely shutdown the plant would be impacted. As a result, in accordance | |||
with task 2.3.5 of Appendix F, the issue was screened to Green. | |||
The inspectors determined that a cross-cutting aspect was associated with this finding | |||
in the area of human performance related to conservative decision making. Specifically, | |||
Entergys decision-making was non-conservative as it related to the processes used to | |||
identify the source of the acrid odor; re-energize the damaged electrical equipment; and | |||
keep a damaged electrical component energized for 14 days prior to its removal from | |||
the MCC. (H.1(b) per IMC 0305) | |||
Enforcement: 10 CFR 50 Appendix B, Criterion XVI, Corrective Action, requires that | |||
measures shall be established to assure conditions adverse to quality, such as failures | |||
and malfunctions are promptly identified and corrected. Contrary to the above, on | |||
January 28, 2009, operations personnel did not identify that a safety-related bucket had | |||
experienced a fault prior to replacing upstream fuses and restoring power to the bucket. | |||
In addition, after replacing the upstream fuses, operations personnel tried to locally shut | |||
the damaged cubicle switch and left damaged equipment energized until February 11, | |||
2009. Entergy entered the issue into the corrective action program as IP2-2009-00342 | |||
and IP2-2009-00483, trained all operations personnel on the requirements to replace | |||
fuses and re-energize electrical equipment, and plans to review operations procedures | |||
Enclosure | |||

for operating electrical equipment. Because the violation was of very low safety | |||
significance and it was entered into the licensees corrective action program, this | |||
violation is being treated as an NCV, consistent with the NRC Enforcement Policy: NCV | |||
05000247/2009002-02, Failure to Identify Damaged Components in EDG | |||
Ventilation Motor Control Center. | |||
.2 Degraded Fire Door to the 480V Vital Bus Room | |||
Introduction: The inspectors identified a NCV of very low safety significance (Green) | |||
related to License Condition 2.K., fire protection program, because Entergy personnel | |||
did not promptly identify and correct a degraded three-hour rated fire door on the west | |||
entrance of the 480 Volt switchgear room. | |||
Description: License Condition 2.K., fire protection program, requires that Entergy | |||
implement and maintain in effect all provisions of the NRC-approved fire protection | |||
program, as approved in part by the NRC Safety Evaluation Report (SER) dated | |||
January 31, 1979. The January 31, 1979, SER requires administrative controls | |||
comparable to those described in NRC Branch Technical Position 9.5-1, Guidelines for | |||
Fire Protection for Nuclear Power Plants Docketed Prior to July 1, 1976. Branch | |||
Technical Position (BTP) 9.5-1 requires that measures be established to assure that | |||
conditions adverse to fire protection, such as deficiencies, deviations, defective | |||
components, and non-conformities are promptly identified, reported, and corrected. | |||
On February 6, 2009, the inspectors performed a fire protection walkdown of the 480- | |||
Volt switchgear room. The inspectors noted the three-hour rated, swing-type fire door | |||
on the west side of the 480-Volt switchgear room was not latched closed. The | |||
inspectors observed the door being held open by the latch mechanism which had not | |||
repositioned to allow the door to shut. The inspectors observed the latch mechanism | |||
did not move freely preventing the door from shutting automatically. The inspectors | |||
shut the door and notified shift operations personnel who tightened latch screws on the | |||
door and wrote a condition report. | |||
On February 18, the inspectors identified the 480-Volt switchgear room door was not | |||
latched shut again. The inspectors determined the door could not be closed due to | |||
interference from the latch mechanism screw which had backed out. The inspectors | |||
notified operations of the fire door issue. Operations personnel re-inserted the latch | |||
mechanism screw and documented the issue in a condition report. The inspectors | |||
questioned whether it was appropriate to re-insert a screw that had backed out on its | |||
own in such a short period of time. Entergy personnel subsequently inspected the door | |||
on February 23 and identified the screws holding the latch mechanism to the door were | |||
stripped. Entergy personnel tapped new holes in the door latch mechanism and | |||
installed new screws. | |||
On March 3, inspectors identified the 480-Volt switchgear room fire door not latched | |||
shut again. The inspectors observed the door was being held open by the latch | |||
mechanism which had not repositioned to allow the door to shut. The inspectors noted | |||
the latch mechanism did not move freely preventing the door from shutting | |||
automatically. The inspectors notified operations personnel of the non-functioning fire | |||
door and Entergy subsequently had a locksmith inspect the latch. The locksmith | |||
installed a new latch mechanism on March 3 and determined the latch issues observed | |||
were age-related due to interaction of wear products from the latch interfering with the | |||
moving portions of the latch, as a result of latching and unlatching door operations. | |||
Enclosure | |||
14 | |||
Entergy entered the issue into the corrective action program on March 3, performed an | |||
inspection of all fire doors onsite, and identified and corrected issues with other required | |||
fire doors. | |||
Analysis: The inspectors identified a performance deficiency because Entergy personnel | |||
did not identify and correct the non-functional fire door. The finding was more than | |||
minor because it is associated with the protection against external factors attribute of | |||
the Mitigating Systems cornerstone and affected the cornerstone objective of ensuring | |||
the reliability of systems that respond to initiating events to prevent undesirable | |||
consequences. Specifically, in the event of a large fire in the 480-Volt switchgear room | |||
or the turbine building, the affected fire door is credited to prevent the spread of fire from | |||
one area to the other area. This fire door, when degraded, impacts the reliability of | |||
Technical Position | mitigating systems in the 480-Volt switchgear room that are relied upon during a large | ||
fire in the turbine building, and vice versa. | |||
Volt switchgear | This finding was evaluated using Phase 1 of IMC 0609 Appendix F, Fire Protection | ||
Significance Determination Process. Since the area in question had a fire watch | |||
posted during the time the door was degraded, an adequate level of protection was | |||
maintained to compensate for the degraded door and resulted in the finding being of | |||
very low safety significance. As such according to task 1.3.1, the inspectors determined | |||
the finding was Green. | |||
The inspectors determined that the finding had a cross-cutting aspect in the area of | |||
problem identification and resolution because Entergy personnel did not thoroughly | |||
evaluate a degraded fire door latch on several occasions, such that the resolution of the | |||
problems addressed the causes. (P.1(c) per IMC 0305) | |||
Enforcement: License Condition 2.K., fire protection program, requires that Entergy | |||
implement and maintain in effect all provisions of the NRC-approved fire protection | |||
program, as approved in part by the NRC Safety Evaluation Report (SER) dated | |||
January 31, 1979. The January 31, 1979, SER requires administrative controls | |||
comparable to those described in NRC Branch Technical Position 9.5-1, Guidelines for | |||
Fire Protection for Nuclear Power Plants Docketed Prior to July 1, 1976. Branch | |||
Technical Position 9.5-1 requires that measures be established to assure that conditions | |||
adverse to fire protection, such as deficiencies, deviations, defective components, and | |||
non-conformities are promptly identified, reported, and corrected. | |||
Contrary to the above, Entergy personnel did not promptly identify and then | |||
subsequently correct the non-functional 480-Volt switchgear fire door. This fire door | |||
was identified by inspectors in a non-functional state on February 6, February 18, and | |||
again on March 3, 2009. Entergy entered the issue into the corrective action program | |||
as IP2-2009-00526, IP2-2009-00680, IP2-2009-00709, IP2-2009-00834, IP2-2009- | |||
00842, and IP2-2009-00843. Because the violation was of very low safety significance | |||
and it was entered into the licensees corrective action program, this violation is being | |||
treated as an NCV, consistent with the NRC Enforcement Policy: NCV | |||

Maintenance Rule samples were reviewed and represented three inspection samples: | |||
* RWST level indication system; | |||
* EDG fuel injection system; and | |||
* 480-Volt switchgear system. | |||
b. Findings | |||
Introduction: The inspectors identified a NCV of very low safety significance (Green) | |||
related to TS 5.4.1, Administrative Controls: Procedures, because Entergy did not | |||
maintain an adequate maintenance procedure for a safety-related electrical motor | |||
control center (MCC). Specifically, the eight-year maintenance procedure for the | |||
affected EDG ventilation MCC did not contain an adequate method to identify high | |||
resistance connections within the cubicle. | |||
Description: On January 28, 2009, operations personnel identified an acrid odor coming | |||
from the EDG building. Subsequent personnel investigation revealed a charred cubicle | |||
in a safety-related 480-Volt MCC. Specifically, cubicle 4N, in the EDG ventilation MCC, | |||
experienced a phase-to-phase fault that caused the upstream 175 amp fuses to open | |||
and de-energize the MCC. Entergy personnel subsequently generated a condition | |||
report (CR) that was closed to a work request to troubleshoot and repair the cubicle. | |||
Entergy personnel removed the damaged cubicle from the MCC on February 6 and | |||
determined the likely cause to be a high-resistance connection between the cubicle | |||
switch and 30 amp fuse clip on the C phase resulting in long-term overheating. This | |||
overheating condition degraded the insulation between two of the three phases over | |||
time and eventually resulted in a phase-to-phase fault on January 28, 2009. | |||
The inspectors reviewed the 8-year maintenance procedure 2-MCC-003-ELC, | |||
Klockner-Moeller, Series 200, 480 Volt Motor Control Center Preventive Maintenance, | |||
which was performed on the affected EDG ventilation MCC on April 6, 2008. The | |||
inspectors noted that the procedure was revised the same day to allow performance of | |||
the maintenance without de-energizing the equipment. The revision resulted in portions | |||
of the cubicle cleaning and inspection procedure not being performed because they | |||
could not be safely performed while the cubicle was energized. The inspectors | |||
determined that the procedure revision on April 6, 2008, was inappropriately treated as | |||
an editorial revision without a technical evaluation of the change performed. In addition, | |||
following interviews with Entergy personnel, it was determined that maintenance had not | |||
been performed on this MCC prior to April 6, 2008. | |||
Enclosure | |||
17 | |||
The inspectors reviewed industry guidance for performing switchgear maintenance and | |||
energized. | determined that Entergy did not include standard maintenance practices typically | ||
utilized by its staff that would have identified a high resistance connection in the cubicle. | |||
Specifically, continuity checks across contacts and switches were not performed, fuse | |||
clip tensions and tightness were not performed, and all terminations could not be | |||
checked due to the decision to perform the maintenance with portions of the cubicle | |||
energized. In addition, the inspectors determined the EDG ventilation MCCs were not | |||
included in Entergys thermography program, contrary to Entergy corporate preventive | |||
maintenance templates. The inspectors determined that not performing thermography | |||
on the EDG ventilation MCC constituted a missed opportunity to identify the high | |||
resistance condition. | |||
It is reasonable to consider the high resistance connection existed during the | |||
maintenance performed on April 6, 2008, because high resistance connections do not | |||
develop into phase-to-phase faults over a short period of time. This is an underlying | |||
assumption for performing switchgear maintenance, which is intended to identify and | |||
correct loose/high resistance connections, on an eight-year periodicity. In addition, | |||
Entergys corporate template for switchgear maintenance recommends a six-year | |||
periodicity and thermography every year. It is reasonable to expect Entergy to be aware | |||
of the existing industry guidance as well as the Entergy corporate maintenance | |||
templates. | |||
Entergy entered the issue into the CAP as IP2-2009-00342 and IP2-2009-00483, | |||
scoped the EDG ventilation MCC into the existing thermography program, performed an | |||
extent-of-condition review that identified 21 additional panels that should be in the | |||
thermography program, and plans to revise the maintenance procedure. | |||
Analysis: The inspectors identified a performance deficiency because Entergy did not | |||
maintain an adequate maintenance procedure for the safety-related EDG ventilation | |||
MCC. This issue was more than minor because the finding was associated with the | |||
external factors attribute of the Initiating Events cornerstone and impacted the initiating | |||
events cornerstone objective of limiting the likelihood of those events that upset plant | |||
stability and challenge critical safety systems during shutdown as well as power | |||
operations. Specifically, the high resistance connection degraded into a phase-to-phase | |||
fault and increased the likelihood of a fire in the EDG building. The condition was | |||
evaluated by a Senior Reactor Analyst utilizing Phase 2 of IMC 0609 Appendix F, Fire | |||
Protection Significance Determination Process. It was determined that in the event of a | |||
fire consuming the MCC, no transient would be placed on the plant and no components | |||
required to safely shutdown the plant would be impacted. As a result, in accordance | |||
with task 2.3.5 of Appendix F, the issue was screened to Green. | |||
The inspectors determined that the finding had a cross-cutting aspect associated with | |||
the area of problem identification and resolution related to the use of operating | |||
experience (OE). Specifically, Entergy personnel did not implement industry | |||
recommended practices, or an alternate equivalent method, for identifying high | |||
resistance connections in electrical switchgear. (P.2(b) per IMC 0305) | |||
Enforcement. TS 5.4.1 Administrative Controls: Procedures, states, Written | |||

Revision 2. Appendix A of RG 1.33 requires procedures for maintenance activities that | |||
Enclosure | |||
18 | |||
can affect the performance of safety related equipment. Contrary to the above, Entergy | |||
did not maintain a maintenance procedure for a safety-related MCC cubicle. | |||
Specifically, the eight-year maintenance procedure, first performed on April 6, 2008, did | |||
not contain an adequate method to identify and correct high resistance connections in | |||
the cubicle. Entergy entered the issue into the CAP as IP2-2009-00342 and IP2-2009- | |||
00483. Because the violation was of very low safety significance and it was entered into | |||
the licensees corrective action program, this violation is being treated as an NCV, | |||
consistent with the NRC Enforcement Policy: NCV 05000247/2009002-04, Inadequate | |||

Introduction: The inspectors identified a NCV of very low safety significance (Green) | |||
related to 10 CFR 50.65(a)(4) because Entergy staff did not adequately assess the risk | |||
associated with the unavailability of the Refueling Water Storage Tank (RWST) level | |||
indication during planned maintenance on the level transmitters and instrumentation. | |||
Description: On February 6, 2009, Entergy staff performed maintenance on the RWST | |||
level indication system. The inspectors identified that the online risk assessment did not | |||
consider planned maintenance on the RWST level indication, as required by 10 CFR | |||
50.65(a)(4). The inspectors reviewed the work activity and noted the maintenance | |||
scheduling software used by Entergy did not have the RWST maintenance coded as a | |||
risk-significant activity. Entergys maintenance planning process prompts the | |||
organization to evaluate the risk impact of all maintenance activities coded as risk- | |||
significant. Therefore, a risk assessment was not performed for the quarterly RWST | |||
level indication maintenance as required. In addition, the RWST level indication was not | |||
represented in Entergys interactive risk model. Entergy staff subsequently updated the | |||
risk model to include the RWST level indication and subsequently assessed the online | |||
Enclosure | |||
19 | |||
risk for the maintenance which resulted in a measurable increase in the core damage | |||
frequency (CDF). The increase in CDF was not large enough to require entrance into | |||
the higher risk category per Entergy procedures. In addition, the increase in CDF (1.1E- | |||
6) combined with the limited duration of the maintenance (15 hours) resulted in a | |||
relatively small incremental core damage probability deficit (1.9E-9). | |||
The inspectors determined this same maintenance activity is modeled in the Indian Point | |||
Unit 3 risk model. Entergy entered the issue into the corrective action program (CR-IP2- | |||
2009-00342), updated the risk model to include the maintenance activity, assessed the | |||
risk, and appropriately coded the maintenance activity to ensure it would be risk | |||
assessed in the future. | |||
Analysis: The inspectors identified a performance deficiency in that Entergy staff did not | |||
assess the increase in plant risk resulting from planned maintenance activities on RWST | |||
level instrumentation as required by 10 CFR 50.65(a)(4). The inspectors determined | |||
that this finding was more than minor because it was a risk assessment issue in which | |||
Entergy personnel did not consider risk significant SSCs that were unavailable during | |||
maintenance. Specifically, RWST level indication is included in Table 2 of the plant | |||
specific Phase 2 SDP risk-informed inspection notebook. The inspectors assessed the | |||
significance of this issue in accordance with IMC 0609, Appendix K, Maintenance Risk | |||
Assessment and Risk Management Significance Determination Process. The | |||
inspectors determined that this finding was of very low safety significance (Green) | |||
because the incremental core damage probability deficit was less than 1E-6. | |||
The inspectors determined that the finding had a cross-cutting aspect in human | |||
performance related work control. Specifically, Entergy personnel did not appropriately | |||
plan work activities by incorporating risk insights for affected plant equipment. (H.3(a) | |||
per IMC 0305) | |||
Enforcement: 10 CFR 50.65 (a)(4) states, in part that licensees shall assess and | |||
manage the increase in risk that may result from the proposed maintenance activities | |||
before performing those activities. Contrary to the above, on February 6, 2009, Entergy | |||
performed maintenance on the RWST level indication system without assessing the | |||
increase in risk. Entergy entered the issue into the corrective action program (CR-IP2- | |||
2009-00342. Because this issue is of very low safety significance and is entered into | |||
Entergys corrective action program, this violation is being treated as an NCV consistent | |||
the NRC Enforcement Policy: NCV 05000247/2009002-05, Failure to Include RWST | |||
Level Maintenance In Online Risk Assessment. | |||
1R15 Operability Evaluations (71111.15 - 7 samples) | |||
a. Inspection Scope | |||
The inspectors reviewed operability evaluations to assess the acceptability of the | |||
evaluations, the use and control of compensatory measures when applicable, and | |||
compliance with Technical Specifications. The inspectors reviews included verification | |||
that operability determinations were performed in accordance with procedure | |||
ENN-OP-104, Operability Determinations. The inspectors assessed the technical | |||
adequacy of the evaluations to ensure consistency with the Technical Specifications, | |||
UFSAR, and associated design basis documents. The documents reviewed are listed in | |||
Enclosure | |||

the Attachment. The following operability evaluations were reviewed and represented | |||
seven inspection samples: | |||
* Proximity of 480-Volt vital motor control center to an uninsulated steam line; | |||
* Leakage from condensate storage tank (CST) return piping; | |||
* Impacts of scaffolding built in the vicinity of the 21 and 22 component cooling water | |||
heat exchangers; | |||

the return line relative to the leak location provided assurance that, in the event the CST | |||

a. Inspection Scope | |||
The inspectors reviewed one temporary plant modification package for securing | |||
minimum flow lines on the motor driven auxiliary boiler feedwater pumps (ABFPs) and | |||
controlling the operation on the ABFPs through a temporary operating procedure during | |||
repairs of the CST return piping. The inspectors verified the design bases, licensing | |||
bases, and performance capability of the system was not degraded by the temporary | |||
modification. The inspectors review included Entergys engineering evaluation for | |||
determining the ABFPs could start with the pumps required minimum flow being | |||
achieved through the internal thrust balance lines while the minimum flow lines were | |||
isolated. In addition, the inspectors interviewed plant staff, and reviewed issues entered | |||
into the corrective action program to determine whether Entergy had been effective in | |||
identifying and resolving problems associated with the temporary modification. The | |||
documents reviewed are listed in the Attachment. | |||

1R19 Post-Maintenance Testing (71111.19 - 6 samples) | |||
a. Inspection Scope | |||
The inspectors reviewed post-maintenance test procedures and associated testing | |||
activities for selected risk-significant mitigating systems, and assessed whether the | |||
effect of maintenance on plant systems was adequately addressed by control room and | |||
engineering personnel. The inspectors verified that: test acceptance criteria were clear, | |||
the test demonstrated operational readiness and were consistent with design basis | |||
documentation; test instrumentation had current calibrations, and appropriate range and | |||
accuracy for the application; and the tests were performed as written, with applicable | |||
prerequisites satisfied. Upon completion of the tests, the inspectors verified that | |||
equipment was returned to the proper alignment necessary to perform its safety function. | |||
Post-maintenance testing was evaluated for conformance with the requirements of 10 | |||
CFR 50, Appendix B, Criterion XI, Test Control. The documents reviewed are listed in | |||
the Attachment. The following post-maintenance activities were reviewed and | |||
represented six inspection samples: | |||

was capable of performing the required safety functions. The inspectors evaluated the | |||
surveillance tests against the requirements in Technical Specifications. The documents | |||
reviewed during this inspection are listed in the Attachment. The following surveillance | |||
tests were reviewed and represented six inspection samples: | |||

* 0-SOP-LEAKRATE-001, RCS Leakrate Surveillance, Evaluation, and Leak | |||
Identification. | |||
b. Findings | |||
Introduction. The inspectors identified a NCV of very low safety significance (Green) | |||
related to 10 CFR 50.55a, Codes and standards, because Entergys procedure 2-PT- | |||
Q031A did not contain appropriate acceptance criteria for determining that safety- | |||
related check valves performed their safety function when required in accordance with | |||
the American Society of Mechanical Engineers (ASME) OM Code. | |||
Description. Entergy procedure 2-PT-Q031A, 21 Auxiliary Component Cooling Pump | |||
(ACCP), is an In-Service Test (IST) procedure that demonstrates the operability of the | |||
21 ACCP, the pump bypass line check valve (755), the 21 ACCP discharge check valve | |||
(755B), and the 22 ACCP discharge check valve (755A) in accordance with Technical | |||
Specification (TS) 5.5.6, Inservice Testing Program. | |||
The test established a single acceptance criterion to determine if the discharge check | |||
valve on the 22 ACCP train shuts when the parallel trains 21 ACCP is providing design | |||
flow. The acceptance criterion was that no reverse rotation is observed on the 22 | |||
ACCP. Although NUREG-1482, Guidelines for Inservice Testing at Nuclear Power | |||
Plants identifies the methodology of using reverse pump rotation as an acceptable | |||
means of testing, Entergys site-specific experience in 2005 demonstrated this particular | |||
method was not effective to maintain the ACCP discharge check valve safety function. | |||
Specifically, when 2-PT-Q031A was performed on January 19, 2005, the 21 ACCP | |||
failed the performance test because check valve 755A was determined to be in the | |||
open position. However, the 22 ACCP did not rotate in the reverse direction. Following | |||
disassembly of valve 755A, engineers determined the valve remained in the open | |||
position because of excessive clearances between the hinge pin and hinge pin | |||
bushings. Entergy personnel determined the check valve was likely in this condition | |||
following maintenance on the valve in late 2004. CR-IP2-2005-0252 was written to | |||
document and evaluate the issue. The issue was previously documented in LER | |||
05000247/2005001-00 and NRC NCV 50-247/2005003-01. At that time, Entergy | |||
personnel concluded the test criteria established in 2-PT-Q031A was acceptable but | |||
that post-maintenance tests on the check valve should include amplifying comments | |||
Enclosure | |||
23 | |||
directing the performance of the IST following maintenance. Entergy personnel | |||
concluded that the IST was adequate because the low pump head that caused the | |||
pump performance test to fail led to troubleshooting that identified that check valve | |||
755A was stuck open. | |||
The inspectors determined that the criterion for determining operability of 755A in test 2- | |||
PT-Q013A was inadequate because the criterion in the procedure previously failed to | |||
identify that 755A remained in the open position in January 2005 and 2-PT-Q013A does | |||
not identify any other criteria, including using pump head, to determine operability of | |||
755A. Additionally, the inspectors determined the test criterion for check valve 755A | |||
and 755B were not consistent with the following ASME Code requirements: | |||
* The ASME OM Code 2001 Subsection ISTA-3160 states that procedures shall | |||
contain the Owner-specified reference values and acceptance criteria; | |||
* The ASME OM Code 2001 Subsection ISTC-1400 (c) states it is the Owners | |||
responsibility to ensure that the application, method, and capability of each | |||
nonintrusive technique is qualified; and | |||
* The ASME OM Code 2001 Subsection ISTC-3530 states obturator movement | |||
shall be determined by exercising the valve while observing an appropriate | |||
indicator. | |||
Analysis. The inspectors determined that the performance deficiency was more than | |||
minor because it was associated with the procedure quality attribute of the Mitigating | |||
System cornerstone and adversely affected the cornerstone objective to ensure the | |||
reliability of systems that respond to initiating events to prevent undesirable | |||
consequences. Specifically, the test criterion used in procedure 2-PT-Q013A did not | |||
ensure that valve 755A reliably performed its safety function when tested as | |||
demonstrated by testing performed in January 2005. The inspectors determined that | |||
the performance deficiency was of very low safety significance (Green) using IMC 0609, | |||
Attachment 4, Phase 1 - Initial Screening and Characterization of Findings. | |||
Specifically, the inspectors determined that this finding was of very low safety | |||
significance because the finding did not result in a loss of safety function and did not | |||
screen as potentially risk-significant due to external events initiating events. | |||
The inspectors determined the finding had a cross-cutting aspect related to effective | |||
corrective actions in the corrective action program component of the problem | |||
identification and resolution area. Specifically, Entergy did not implement effective | |||
corrective actions to resolve the testing inadequacy since 2005 during subsequent | |||
quarterly testing. Additionally, the issue was considered to be indicative of current | |||
performance because personnel when initially responding to inspector questions | |||
concluded the acceptance criteria were adequate. (P.1(d) per IMC 0305) | |||
Enforcement. 10 CFR 50.55a, Codes and standards, states that pumps and valves | |||
which are classified as ASME code Class 1, Class 2, and Class 3 must meet the | |||
inservice test requirements set forth in the ASME OM Code (2001 edition for Indian | |||
Point Unit 2). Furthermore, inservice tests to verify operational readiness of pumps and | |||
valves, whose function is required for safety must comply with the requirements of the | |||
ASME OM Code. The ASME OM Code 2001 Subsection ISTC-1400 (c) states it is the | |||
Owners responsibility to ensure that the application, method, and capability of each | |||
nonintrusive technique is qualified. In addition, the ASME OM Code 2001 Subsection | |||
ISTC-3530 states obturator movement shall be determined by exercising the valve | |||
Enclosure | |||
24 | |||
while observing an appropriate indicator. Contrary to the above, from February 2005 | |||
until February 2009, Entergy procedure 2-PT-Q031A, did not include appropriate | |||
acceptance criteria for demonstrating operability of valve 755A. Specifically, the test did | |||
not utilize a qualified technique for testing the check-valve and did not verify check valve | |||
movement by observing an appropriate indicator. Because ACCP performance tests | |||
since 2004 demonstrated satisfactory performance of the ACCPs at design flows, no | |||
actual impact to the operability of the ACCPs was evident. Because this violation was | |||
of very low safety significance and it was entered into Entergys corrective action | |||
program (IP2-2009-1312), this violation is being treated as an NCV, consistent with the | |||
NRC Enforcement Policy. NCV 2009002-06, Inadequate Test Acceptance Criteria | |||

1EP6 Drill Evaluation (71114.06 - 1 sample) | |||
a. Inspection Scope | |||
The inspectors evaluated an emergency classification conducted on February 23, 2009, | |||
during a licensed-operator requalification simulator training evaluation. The inspectors | |||
observed an operating crew in the simulator respond to various, simulated initiating | |||
events that ultimately resulted in the simulated implementation of the emergency plan. | |||
In particular, the inspectors verified the adequacy and accuracy of the simulated | |||
emergency classification of a Site Area Emergency. While other simulated | |||
classifications were made, the inspectors verified that the initial classification was | |||
appropriately credited as an opportunity toward NRC performance indicator data. The | |||
inspectors observed the management evaluator and training critique following | |||
termination of the scenarios, and verified that significant performance deficiencies were | |||
appropriately identified and addressed within the critique and the corrective action | |||
program. Also, the inspectors reviewed the summary performance report for the | |||
evaluation and verified that appropriate attributes of drill performance including | |||
deficiencies were captured. This evaluation constituted one inspection sample. | |||

2. RADIATION SAFETY | |||
Cornerstone: Occupational Radiation Safety (OS) | |||
2OS1 Access Control to Radiologically Significant Areas (71121.01 - 16 samples) | |||
a. Inspection Scope | |||
From March 23 through March 27, 2009, the inspectors conducted the following | |||
activities to verify that Entergy was properly implementing physical, engineering, and | |||
administrative controls for access to high radiation areas, and other radiologically | |||
controlled areas, and that workers were adhering to these controls when working in | |||
these areas. Implementation of the access control program was reviewed against the | |||
Enclosure | |||
25 | |||
criteria contained in 10 CFR 20, site technical specifications, and Entergys procedures | |||
required by the Technical Specifications as criteria for determining compliance. | |||
This inspection activity represents completion of sixteen (16) samples relative to this | |||
inspection area. The inspector performed independent radiation dose rate | |||
measurements and reviewed the following items: | |||

(6) Access controls related condition reports were reviewed since the last inspection | |||
in this area. Staff members were interviewed and documents reviewed to | |||
determine that follow-up activities are being conducted in an effective and timely | |||
manner, commensurate with their safety and risk. | |||
(7) For repetitive deficiencies or significant individual deficiencies in problem | |||
identification and resolution, the inspectors determined if the licensees | |||

(9) The inspectors observed aspects of various on-going activities to confirm that | |||
radiological controls, such as required surveys, area postings, job coverage, and | |||
job site preparations were conducted. The inspectors verified that personnel | |||
dosimetry was properly worn and that workers were knowledgeable of work area | |||
conditions. The inspectors attended pre-planning meetings for work described | |||
earlier in the report. | |||

Description. During the period January 2009 through March 2009, six instances of | |||
electronic dosimeter dose rate alarms were recorded by the access control system for | |||
Unit 2 personnel in the RCA (Unit 3 had 15 instances). During this period, Entergy | |||
personnel inconsistently utilized an informal process of reviewing the alarms without a | |||

the inspectors identified that no investigation or follow-up had occurred. In some cases, | |||

made resultant investigations more challenging to perform. In other cases, the alarms | |||
were not identified until the worker attempted to re-enter the RCA and the access control | |||
system required manual override to un-lock the occurrence to allow entry into the RCA. | |||
Reviews, exposure estimates, actual exposures and post job reviews. | The inspectors noted that the controlling Entergy procedure for this activity, EN-RP-203, | ||
Dose Assessment, specifies that for a dose-rate alarm that is unanticipated or un- | |||
briefed, several actions are required, one of which is to initiate a condition report, | |||
another is to document the investigation using an attachment in the procedure. Contrary | |||
to EN-RP-203, for these 21 instances, no condition reports or attachments were | |||
generated with a detailed investigation prior to the workers re-entering the radiologically | |||
controlled area. The highest exposure received by these workers during their entry, as | |||
indicated by their electronic dosimeter and logged by the access control system, was 33 | |||
mRem, while most dosimeters indicated less than 1 mRem for the entry. | |||
Analysis. The inspectors determined that the failure to generate a condition report, as | |||
well as the failure to adequately investigate six unplanned or un-briefed electronic | |||
dosimeter alarms prior to re-entry into the Unit 2 RCA, as required by station procedure | |||
was a performance deficiency. This performance deficiency was within Entergy | |||
personnels ability to foresee and correct, and should have been prevented. This issue | |||
was not subject to traditional enforcement, in that it did not have actual safety | |||
consequence, it was not an issue that had the potential to impact NRCs ability to | |||
perform its regulatory function, and there were no willful aspects. | |||
The finding is more than minor because it is associated with the Occupational Radiation | |||
Safety cornerstone attribute of programs and process, and adversely affected its | |||
objective to ensure adequate protection of worker health and safety from exposure to | |||
radiation. Moreover, the inspectors identified a programmatic deficiency to maintain and | |||
implement programs to keep exposures as low as reasonably achievable, because | |||
multiple examples were identified regarding the failure to satisfy station radiation | |||
protection procedures. Specifically, in six cases, Entergy did not fully evaluate dose rate | |||
alarms received by workers in radiologically controlled areas of the plant. Using the | |||
Occupational Radiation Safety Significance Determination Process, the inspectors | |||
determined that the finding was of very low safety significance (Green) because it did not | |||
involve: (1) as low as is reasonably achievable planning and controls, (2) an | |||
Enclosure | |||
28 | |||
overexposure, (3) a substantial potential for overexposure, or (4) an impaired ability to | |||
assess dose. | |||
The inspectors determined that the finding had a cross-cutting aspect related to | |||
procedural adherence in the Work Practices component of the Human Performance | |||
area. Specifically, Entergy employees did not follow procedures to generate condition | |||
reports and document investigations when high-dose rate alarms were received by | |||
workers. (H.4 (b) per IMC 0305) | |||
Enforcement. Technical Specification 5.4.1.a, Procedures, requires that Entergy | |||
establish, implement, and maintain procedures specified in Regulatory Guide (RG) 1.33, | |||
Revision 2, Appendix A., Section 7.e, radiation protection procedures for personnel | |||
monitoring. Entergy procedure EN-RP-203, Revision 2, Section 5.11, requires that a | |||
condition report be written for each unplanned or un-briefed electronic dosimeter dose- | |||
rate alarm. Contrary to the above, the inspectors identified through a review of | |||
electronic dosimeter log information from January 2009 through March 2009, six | |||
instances of unanticipated or un-briefed electronic dosimeter dose-rate alarms when the | |||
procedure was not implemented and condition reports were not generated. Because | |||
this finding was of very low safety significance and it was entered into the corrective | |||
action program as CR-IP3-2009-001253 and CR-IP3-2009-001318, this violation is | |||
being treated as an NCV, consistent with the NRC Enforcement Policy. NCV | |||

2OS2 ALARA Planning and Controls (71121.02 - 12 samples) | |||
a. Inspection Scope | |||
From March 23 through March 27, 2009, the inspectors conducted the following | |||
activities to verify that Entergy was properly maintaining individual and collective | |||
radiation exposures as low as is reasonably achievable (ALARA). Implementation of the | |||
ALARA program was reviewed by inspectors against the criteria contained in 10 CFR | |||
20, applicable industry standards, and Entergys procedures. | |||
This inspection activity represents completion of twelve (12) samples relative to this | |||
inspection area. | |||

4OA2 Identification and Resolution of Problems (71152) | |||
.1 Routine Problem Identification & Resolution Program Review | |||
a. Inspection Scope | |||
As required by Inspection Procedure 71152, Identification and Resolution of Problems, | |||
and to identify repetitive equipment failures or specific human performance issues for | |||
follow-up, the inspectors performed a daily screening of all items entered into Entergys | |||
corrective action program. The review was accomplished by accessing Entergys | |||
computerized database for condition reports, and attending condition report screening | |||
meetings. | |||
In accordance with the baseline inspection modules, the inspectors selected corrective | |||
action program items across the Initiating Events, Mitigating Systems, and Barrier | |||
Integrity cornerstones for further follow-up and review. The inspectors assessed | |||
Entergys threshold for problem identification, adequacy of the causal analysis, extent of | |||
condition reviews, and operability determinations, and timeliness of the associated | |||
corrective actions. The condition reports reviewed during this inspection are listed in the | |||
Attachment. | |||
b. Findings | |||
No findings of significance were identified | |||
4OA3 Event Followup | |||
.1 Condensate Return Line Leak on February 15, 2009 | |||
a. Inspection Scope | |||
On February 15, 2009, an operator observed indications of wetness in a pipe sleeve in | |||
the floor of the auxiliary feed pump building. The operator notified the control room. | |||
Chemistry samples of the water were drawn and analyzed. On February 16, Entergy | |||
determined the chemistry results indicated the water was from the condensate storage | |||
tank (CST) return line. The inspectors reviewed the technical specifications (TS) to | |||
determine whether operators entered the applicable TS action statements for the CST | |||
and completed required actions to administratively determine the back-up on-site city | |||
water tank was available, if needed, to provide water to the auxiliary feedwater pumps. | |||
The inspectors reviewed Entergys operability evaluation of the CST to determine | |||
whether it was technically supported. In addition, the inspectors reviewed the impact of | |||
the leak on the auxiliary feed water system which utilizes the CST as a primary source of | |||
water and circulates water back to the CST through the CST return piping. The | |||
inspectors also reviewed chemistry and radiological samples taken of the water to assess | |||
the environmental impact of the leak and determine if the release was below NRC | |||
regulatory limits for liquid effluents. | |||
Enclosure | |||
32 | |||
b. Findings and Observations | |||
No findings of significance were identified. | |||
Entergy excavated a portion of the CST piping in the area of the identified leakage and | |||
determined that the CST return pipe was leaking due to a hole the pipe where a small | |||
area of a protective coating was missing. Entergy also identified two additional areas of | |||
piping with metal loss that did not exceed ASME Code minimum required wall thickness. | |||
However, the areas were repaired while the opportunity existed. Entergy removed the | |||
portion of pipe with the localized defects and sent the specimen to a laboratory for | |||
analysis to identify the causes. The inspectors determined that the actions Entergy | |||
implemented to evaluate and repair the leaking CST pipe to restore operability to the | |||
CST were adequate and in accordance with their operating license. Additionally, the | |||
inspectors determined that the evaluations and actions Entergy performed to evaluate | |||
and maintain operability of the auxiliary feed pumps were adequate. Entergy analyzed | |||
the water leaking up through the sleeve and determined it was CST water based on | |||
hydrazine and tritium levels. The amount of tritium detected in the water was consistent | |||
with that found in the CST, for example, analyses of samples of water from the leak | |||
returned 2000 - 2300 picocuries per liter (pCi/l). The release was determined to be | |||
below the NRC regulatory limits for liquid effluents. For added perspective, while not | |||
drinking water, the Environmental Protection Agency environmental limit for drinking | |||
water requires tritium levels less than 20,000 pCi/l. | |||
Entergy initiated a root cause analysis to determine causes of the leak that is scheduled | |||
to be completed in May 2009. At the end of the inspection period, the inspectors were | |||
monitoring the performance of Entergy in implementing its corrective action program to | |||
address the issue and develop a root cause evaluation and further corrective actions. | |||

.1 Continued Groundwater Sampling Effort to Monitor Tritium (Deviation Memorandum | |||
Inspection) | |||
a. Inspection Scope | |||
During the week of March 23-27, 2009, the inspectors met with Entergy representatives | |||
to review the results of recent groundwater samples, as well as those taken and | |||
analyzed in 2008. The review was conducted against criteria contained in 10CFR20, | |||
10CFR50, and applicable industry standards. | |||
The review of the data included a comparison of Entergys data with split samples taken | |||
by the NRC of monitoring wells MW-66 and MW-67, as well as the LaFarge sample | |||
point. In all, 47 samples were analyzed and compared from January 2008 through | |||
January 2009. Isotopic analyses were performed and compared at each of the sample | |||
points for: Tritium, Strontium 90, Nickel 63, and gamma emitters such as Cobalt-60 and | |||
Cesium-137. Results of the NRC samples can be found in ADAMS accession numbers: | |||

b. Findings | |||
No findings of significance were identified. | |||
The inspectors concluded that overall, there was agreement between Entergy | |||
personnels results and those independently analyzed by the NRC, and that actions | |||
taken by Entergy have been appropriate. The inspectors also noted that conservative | |||
estimates indicate that the samples represent a very small fraction of the permissible | |||
public dose limits and are negligible with respect to natural background radiation levels. | |||

SUBJECT: INDIAN POINT NUCLEAR GENERATING UNIT 2 - NRC INTEGRATED
INSPECTION REPORT 05000247/2009002
Dear Mr. Pollock:
On March 31, 2009, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection
at Indian Point Nuclear Generating Unit 2. The enclosed integrated inspection report
documents the inspection results, which were discussed on April 15, 2009, with you and other
members of your staff.
The inspection examined activities conducted under your license as they relate to safety and
compliance with the Commissions rules and regulations, and with the conditions of your
license. The inspectors reviewed selected procedures and records, observed activities, and
interviewed personnel.
This report documents seven findings of very low safety significance (Green). Six of these
findings were also determined to be violations of NRC requirements. However, because of their
very low safety significance, and because the findings were entered into your corrective action
program, the NRC is treating these findings as non-cited violations (NCVs) consistent with
Section VI.A.1 of the NRC Enforcement Policy. If you contest any NCV in this report, you
should provide a written response within 30 days of the date of this inspection report, with the
basis for your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control Desk,
Washington D.C. 20555-0001; with copies to the Regional Administrator, Region I; the Director,
Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC
20555-0001; and the NRC Senior Resident Inspector at Indian Point Nuclear Generating Unit 2.
In addition, if you disagree with the characterization of any finding, you should provide a
response within 30 days of the date of this inspection report, with the basis for your
disagreement, to the Regional Administrator and the NRC Resident Inspectors at Indian Point
Nuclear Generating Unit 2. The information you provide will be considered in accordance with
Inspection Manual Chapter 0305.
J. Pollock 2
In accordance with Title 10 of the Code of Federal Regulations Part 2.390 of the NRCs Rules

SUMMARY OF FINDINGS
IR 05000247/2009-002; 01/01/2009 - 03/31/2009; Indian Point Nuclear Generating (Indian
Point) Unit 2; Adverse Weather Protection; Fire Protection; Maintenance Effectiveness;
Maintenance Risk Assessments; Surveillance Testing; and Radiological Access Control.
This report covered a three-month period of inspection by resident and region based inspectors.
Seven findings of very low significance (Green) were identified, six of which were also
determined to be non-cited violations (NCV). The significance of most findings is indicated by
their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609,
Significance Determination Process. The cross-cutting aspect for each finding was
determined using IMC 0305, Operating Reactor Assessment Program. 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.
A. NRC-Identified and Self-Revealing Findings
Cornerstone: Initiating Events
- Green. The inspectors identified a NCV of very low safety significance related to 10 CFR
50, Appendix B, Criterion XVI, Corrective Actions, because Entergy did not promptly
identify and correct an adverse condition related to an electrical fault. Specifically,
personnel did not identify a safety-related cubicle had experienced an electrical fault
prior to replacement of upstream fuses and restoration of power to the damaged cubicle.
Entergy entered the issue into the corrective action program as IP2-2009-00342 and
IP2-2009-00483, trained all operations personnel on the requirements to replace fuses
and re-energize electrical equipment, and plans to revise the operations procedure for
operating electrical equipment.
This issue was more than minor because the finding was associated with the external
factors attribute of the Initiating Events cornerstone and impacted the cornerstone
objective of limiting the likelihood of those events that upset plant stability and challenge
critical safety systems during shutdown as well as power operations. The inspectors
determined that the issue increased the likelihood of a fire in the emergency diesel
generator (EDG) building. The condition was evaluated by a Senior Reactor Analyst
utilizing Phase 2 of IMC 0609 Appendix F, Fire Protection Significance Determination
Process. It was determined that in the event of a fire consuming the MCC, no transient
would be placed on the plant and no components required to safely shutdown the plant
would be impacted. As a result, in accordance with task 2.3.5 of Appendix F, the issue
was screened to Green.
The inspectors determined that a cross-cutting aspect was associated with this finding
in the area of human performance related to conservative decision making. Specifically,
Entergys decision-making was non-conservative related to its decisions on the process
used to identify the source of the acrid odor; re-energize the damaged electrical
equipment; and keep a damaged electrical component energized for 14 days prior to its
removal from the MCC. H.1(b) per IMC 0305] (Section 1R05)

- Green. The inspectors identified a NCV of very low safety significance related to TS 5.4.1, Administrative Controls: Procedures, because Entergy did not maintain an
adequate maintenance procedure for a safety-related electrical motor control center
(MCC). Specifically, the eight-year maintenance procedure for the affected EDG
ventilation MCC did not contain an adequate method to identify high resistance
connections within the cubicle as was expected in the applicable preventative
maintenance industry template. Subsequently, a high resistance connection within the
MCC developed into a phase-to-phase electrical fault on January 28, 2009. Entergy
entered the issue into the corrective action program, scoped the affected MCC and 21
additional MCCs into the sites thermography program, and planned to revise the
maintenance procedure.
This issue was more than minor because the finding was associated with the external
factors attribute of the Initiating Events cornerstone and impacted the cornerstone
objective of limiting the likelihood of those events that upset plant stability and challenge
critical safety systems during shutdown as well as power operations. Specifically, the
high resistance connection degraded into a phase-to-phase fault and increased the
likelihood of a fire in the EDG building. The condition was evaluated by a Senior
Reactor Analyst utilizing Phase 2 of IMC 0609 Appendix F, Fire Protection Significance
Determination Process. It was determined that in the event of a fire consuming the
MCC, no transient would be placed on the plant and no components required to safely
shutdown the plant would be impacted. As a result, in accordance with task 2.3.5 of
Appendix F, the issue was screened to Green.
The inspectors determined that the finding had a cross-cutting aspect associated with
the area of problem identification and resolution related to the use of operating
experience (OE). Specifically, Entergy personnel did not implement industry
recommended practices, or an alternate equivalent method, for identifying high
resistance connections in electrical switchgear. P.2(b) per IMC 0305] (Section 1R12)
Cornerstone: Mitigating Systems
- Green. The inspectors identified a finding of very low safety significance because
Entergy personnel did not adequately implement procedure EN-LI-102, Corrective Action
Process, and promptly identify a condition adverse to quality associated with open
louvers in a fire protection pump room following pump testing on January 14, 2009. The
open louvers resulted in freezing conditions in fire protection piping located in the room
and cracked two six-inch header isolation valves on January 17, 2009. Entergy entered
the issue into the corrective action program and performed a site-wide extent-of-
condition walkdown of louvers.
The finding was more than minor because it was associated with the protection against
external factors attribute of the Mitigating Systems cornerstone and it affected the
cornerstone objective of ensuring the reliability of systems that respond to initiating
events to prevent undesirable consequences. This finding was evaluated using Phase
1 of IMC 0609 Appendix F, Fire Protection Significance Determination Process. The
inspectors determined the issue was of very low safety significance (Green) because
the cracked valves were easily isolated and did not pass sufficient water to render the
fire header non-functional (low degradation rating).
Enclosure

The inspectors determined that the finding had a cross-cutting aspect in the area of
human performance related to work practices - human error prevention techniques.
Specifically, Entergy personnel that routinely tour the 11 fire pump house did not
question the abnormally cold room temperatures. H.4(a) per IMC 0305] (Section 1R01)
- Green. The inspectors identified a NCV of very low safety significance related to License
Condition 2.K., fire protection program, because personnel did not promptly identify and
correct a degraded three-hour rated fire door latch mechanism on the west entrance of
the 480-Volt switchgear room. Specifically, inspectors identified the fire door in a non-
functional state on several instances over the course of a month. Entergy personnel
replaced the fire door latch mechanism on March 3, 2009. This issue was entered into
the corrective action program as six condition reports spanning several weeks and
included an extent of condition walkdown of site fire doors.
The finding was more than minor because it is associated with the protection against
external factors attribute of the Mitigating Systems cornerstone and affected the
cornerstone objective of ensuring the reliability of systems that respond to initiating
events to prevent undesirable consequences. This fire door, when degraded, impacts
the reliability of mitigating systems in the 480-Volt switchgear room that are relied upon
during a postulated large fire in the turbine building, and vice versa. This finding was
evaluated using Phase 1 of IMC 0609 Appendix F, Fire Protection Significance
Determination Process. Since the area in question had a fire watch posted during the
time the door was degraded for an unrelated issue, an adequate level of protection was
maintained to compensate for the degraded door. As such, according to task 1.3.1, the
inspectors determined the finding was Green.
The inspectors determined that the finding had a cross-cutting aspect in the area of
problem identification and resolution because Entergy personnel did not thoroughly
evaluate a degraded fire door latch on several occasions, such that the resolution of the
problems addressed the causes. P.1(c) per IMC 0305] (Section 1R05)
- Green. The inspectors identified a NCV of very low safety significance related to 10 CFR
50.65(a)(4), because Entergy personnel did not adequately assess the risk associated
with the unavailability of the Refueling Water Storage Tank (RWST) level indication
during planned maintenance on the level transmitters and instrumentation. Entergy
entered the issue into the corrective action program (CR-IP2-2009-00342), updated the
risk model to include the maintenance activity, assessed the risk, and appropriately
coded the maintenance activity to ensure it would be risk assessed in the future.
The inspectors determined that this finding was more than minor because it was a
maintenance risk assessment issue in which personnel did not consider risk significant
SSCs that were unavailable during maintenance. The RWST level indication is
specifically listed in Table 2 of the plant specific Phase 2 SDP risk-informed inspection
notebook. The inspectors determined the significance of this issue in accordance with
IMC 0609, Appendix K, Maintenance Risk Assessment and Risk Management
Significance Determination Process. The inspectors determined that this finding was of
very low safety significance because the Incremental Core Damage Probability Deficit
was less than 1E-6.
The inspectors determined that the finding had a cross-cutting aspect in the area of
human performance related to work control. Specifically, Entergy personnel did not
Enclosure
6
appropriately plan work activities by incorporating risk insights for affected plant
equipment. H.3(a) per IMC 0305] (Section 1R13)
- Green. The inspectors identified a NCV of very low safety significance related to 10
CFR 50.55a, Codes and standards, because Entergys procedure, 2-PT-Q031A for an
auxiliary component cooling water pump, did not contain appropriate acceptance criteria
for positively determining that safety-related check valves performed their safety function
when required in accordance with the American Society of Mechanical Engineers
(ASME) OM Code. Specifically, the test used reverse rotation of a parallel pump to
verify that the pumps discharge check valve was closed although previous site-specific
experience demonstrated that the pump impeller would not rotate backwards when the
check valve was stuck open. Entergy entered this issue into their corrective action
program as CR-2009-1312.
The inspectors determined that the performance deficiency was greater than minor
because it was associated with the procedure quality attribute of the Mitigating System
cornerstone and it adversely affected the cornerstones objective to ensure the reliability
of systems that respond to initiating events to prevent undesirable consequences.
Specifically, the test criterion used in procedure 2-PT-Q013A did not ensure that valve
755A reliably performed its safety function when tested as demonstrated by testing
performed in January 2005. The inspectors determined that the performance deficiency
was of very low safety significance (Green) IMC 0609, Attachment 4, Phase 1 - Initial
Screening and Characterization of Findings. Specifically, the inspectors determined
that this finding was of very low safety significance because the finding did not result in
a loss of safety function and did not screen as potentially risk-significant due to external
events initiating events.
The inspectors determined the finding had a cross-cutting aspect related to effective
corrective actions in the corrective action program component of the problem
identification and resolution area. Specifically, Entergy personnel did not implement
effective corrective actions to resolve the testing inadequacy since 2005 and during
subsequent quarterly testing. P.1(d) per IMC 0305] (Section 1R22)
Cornerstone: Occupational Radiation Safety
- Green. The inspectors identified a NCV of very low safety significance related to
Technical Specification 5.4.1.a, Procedures, because Entergy personnel did not
generate condition reports or investigation paperwork for multiple high dose-rate alarms
as required by station procedures. Specifically, personnel did not generate the required
condition reports and adequately document the investigations for six instances of
unplanned or un-briefed electronic dosimeter alarms that occurred between January
2009 and March 2009. The performance deficiency resulted in workers receiving
unanticipated dose rate alarms with no formally-documented investigation prior to
returning to work in a Radiologically Controlled Area. Entergy entered the finding into
the corrective action program as condition report CR-IP3-2009-01253 and 01318.
The finding is more than minor because it is associated with the Occupational Radiation
Safety cornerstone attribute of programs and process, and adversely affected the
objective to ensure adequate protection of worker health and safety from exposure to
radiation. Moreover, the inspectors identified a programmatic deficiency to maintain and
implement programs to keep exposures as low as reasonably achievable, because
Enclosure
7
multiple examples were identified regarding the failure to satisfy station radiation
protection procedures. Using the Occupational Radiation Safety Significance
Determination Process, the inspectors determined that the finding was of very low safety
significance (Green) because it did not involve: (1) as low as is reasonably achievable
planning and controls, (2) an overexposure of an individual, (3) a substantial potential for
overexposure, or (4) an impaired ability to assess dose.
The inspectors determined that the finding had a cross-cutting aspect related to
procedural adherence in the work practices component of the human performance area.
Specifically, Entergy personnel did not follow procedures to generate condition reports
and document investigations when high dose-rate alarms were received by workers.

1R01 Adverse Weather Protection (71111.01 - 1 sample)
Impending Adverse Weather
a. Inspection Scope
The inspectors reviewed the overall preparations and protection of risk-significant
systems for extremely cold weather conditions from January 14 - 19, 2009. The
inspectors reviewed and assessed implementation of the sites adverse weather
preparation procedures and compensatory measures for the affected conditions before
the onset of and during the cold weather conditions. This included verification that
operator actions defined in their adverse weather procedure maintain readiness of
essential systems that are vulnerable to freezing temperatures. The inspectors verified
Entergy personnel implemented periodic equipment walkdowns or other measures to
ensure the condition of plant equipment was operable.
The inspectors also reviewed Entergys corrective action program to review previous
issues associated with cold weather preparations and freezing conditions. Documents
reviewed are listed in the attachment.
b. Findings
Introduction. The inspectors identified a Green finding because Entergy personnel did
not adequately implement procedure EN-LI-102, Corrective Action Process, and
promptly identify a condition adverse to quality associated with stuck-open louvers in a
fire protection pump room following pump testing on January 14, 2009.
Description. On January 17, 2009, during a period of sustained cold weather which
included sub-zero temperatures, control room personnel received a fire panel trouble
alarm indicative of a low-pressure condition in the fire header and dispatched a plant
operator to investigate. The operator identified spraying water from the body of a
ruptured six-inch fire protection valve located in the 11 fire pump house. The operator
isolated the broken valve from the fire header by shutting a manually-operated upstream
valve which stopped the water spray. In addition, the operator observed that the pump
house room was significantly colder than expected and subsequently identified the
rooms ventilation louvers to the outside were mechanically bound in the open position.
The operator disconnected the louver linkage and manually shut the louvers.
Enclosure

On January 21, 2009, the inspectors identified a second six inch valve that was cracked
due to the previous cold weather (freezing) conditions in the fire pump house. Entergy
personnel entered this issue into the corrective action program and performed site
walkdowns to identify additional adverse conditions associated with the cold weather.
The inspectors determined that Entergy did not fully implement Entergy procedure EN-
LI-102, Corrective Action Process. Specifically, EN-LI-102 requires plant personnel to
identify adverse conditions, including cold-weather related conditions, and then enter
them into the CAP for resolution. Attachment 9.2 of the procedure provides examples of
adverse conditions expected to be reported; Section 1 of the Attachment contains
examples of operational conditions requiring entry into the CAP including "events or
conditions that could negatively impact reliability or availability." Additionally, plant
operators should have had heightened awareness to cold weather conditions because
Entergy procedure OAP-008, "Severe Weather Preparations," requires in step 4.3.7,
when freezing conditions are expected, that increased monitoring of plant areas to
monitor for adverse effects on plant equipment and verify that adequate protection is
provided. Operations personnel did not identify abnormal conditions in the 11 fire pump
room that led to the freezing and subsequent rupture of fire protection components.
The inspectors determined it was reasonable for Entergy personnel to identify this issue
because operators should have identified that the louvers failed to shut following a
routine operations test of 11 fire pump on January 14, 2009. In addition, operators
perform tours of the pump house every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and should have identified the room
was much colder than normal.
Analysis. The inspectors identified a performance deficiency because Entergy
personnel did not implement procedure guidance and identify stuck open louvers and a
subsequent second cracked fire header valve in the 11 fire pump house. The finding
was more than minor because it was associated with the protection against external
factors attribute of the Mitigating Systems cornerstone and it affected the cornerstone
objective of ensuring the reliability of systems that respond to initiating events to prevent
undesirable consequences. Specifically, the failure of the six-inch valves impacted the
reliability of the fire header until the ruptured valve was isolated.
This finding was evaluated using Phase 1 of Inspection Manual Chapter (IMC) 0609
Appendix F, Fire Protection Significance Determination Process. The inspectors
determined the issue was of very low safety significance (Green) because the cracked
fire valves were easily isolated and did not pass sufficient water to render the fire
header non-functional. Specifically, the inspectors assigned a low degradation rating to
the fire header because the fire pumps were able to maintain pressure in the fire header
until the ruptured valves were isolated.
The inspectors determined that the finding had a cross-cutting aspect in the area of
human performance related to work practices - human error prevention techniques.
Specifically, Entergy personnel routinely tour the 11 fire pump house did not question
the abnormally cold room temperatures. (H.4(a) per IMC 0305)
Enforcement: Enforcement action does not apply because the performance deficiency
did not involve a violation of a regulatory requirement. Because this finding does not
involve a violation of regulatory requirements and has very low safety significance, it is
identified as FIN 05000247/2009002-01, Failure to Identify Open Louvers in 11 Fire
Pump House.

1R04 Equipment Alignment (71111.04Q - 3 samples)
Partial System Walkdowns
a. Inspection Scope
The inspectors performed partial system walkdowns to verify the operability of redundant
or diverse trains and components during periods of system train unavailability, or
following periods of maintenance. The inspectors referenced the system procedures,
the UFSAR, and system drawings to verify the alignment of the available train supported
its required safety functions. The inspectors also reviewed applicable condition reports
(CR) and work orders to ensure Entergy personnel identified and properly addressed
equipment discrepancies that could potentially impair the capability of the available train,
as required by Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix
B, Criterion XVI, Corrective Action. The documents reviewed during these inspections
are listed in the Attachment.
The inspectors performed a partial walkdown on the following systems, which
represented three inspection samples:
was tagged out for maintenance;
- City water system as a supply to auxiliary boiler feedwater (ABFW) when the
condensate storage tank was declared inoperable due to leakage;
- 21 and 23 ABFW trains when 22 ABFW pump was tagged out and temporary
modifications were applied to 21 and 23 ABFW minimum flow lines.

1R05 Fire Protection (71111.05Q - 5 samples)
a. Inspection Scope
The inspectors conducted tours of several fire areas to assess the material condition and
operational status of fire protection features. The inspectors verified, consistent with the
applicable administrative procedures, that: combustibles and ignition sources were
adequately controlled; passive fire barriers, manual fire-fighting equipment, and
suppression and detection equipment were appropriately maintained; and compensatory
measures for out-of-service, degraded, or inoperable fire protection equipment were
implemented in accordance with Entergys fire protection program. The inspectors
evaluated the fire protection program for conformance with the requirements of License
Condition 2.K. The documents reviewed during this inspection are listed in the

b. Findings
.1 Failure to Identify Damaged Components in EDG Ventilation Motor Control Center
Introduction: The inspectors identified a NCV of very low safety significance (Green)
related to 10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, because Entergy
personnel did not promptly identify and correct an adverse condition related to an
electrical fault. Specifically, personnel did not identify a safety-related cubicle (bucket)
had experienced a fault prior to replacement of upstream fuses and restoration of power
to the cubicle.
Description: On January 28, 2009, operations personnel detected an acrid odor coming
from the emergency diesel generator (EDG) building. Operators entered the EDG
building to investigate the source of the acrid odor and identified that a MCC was de-
energized. Operations personnel did not identify external damage to the MCC; however,
operators did not open MCC panels to inspect for internal damage. Operators checked
the upstream 175 amp supply fuses, located in a different building, and identified that 2
of 3 fuses had blown. Operators opened the downstream breakers on the MCC in the
EDG building and then replaced the 175 amp supply fuses in the control building. Once
operators replaced the blown fuses, they re-energized the EDG building MCC#1, and
subsequently began to locally shut all of the cubicle switches. When operators
attempted to shut the switch associated with cubicle 4N, the switch did not function as
expected. Operators then opened the panel for cubicle 4N and identified charred
electrical components.
Entergy personnel generated a D level condition report (CR) for cubicle 4N on the
basis that it supplies a non safety-related (NSR) EDG room heater. Entergy personnel
closed the CR to a work request to troubleshoot and repair the NSR heater. However,
the inspectors questioned the classification of the MCC and determined that the charred
components were safety related (SR). Cubicle 4N contains a SR main line switch and
SR 30 amp main line fuses. The 30 amp fuses are SR to isolate the NSR heaters from
the MCC in the event of a room heater fault. The inspectors also questioned the
appropriateness of leaving the damaged cubicle in the energized MCC. Following
inspector questions, Entergy staff issued another CR and removed the damaged cubicle
from the MCC on February 11. During removal of the charred cubicle, maintenance
personnel were unable to disconnect the main line cables due to arc-welding at the
termination and subsequently had to cut two of the three cables upstream of the
termination and cubicle switch. These cables and the line side of the switch were
energized from January 28 until February 11. After the damaged cubicle was removed,
engineering personnel performed an inspection and determined that the fault originated
from a high resistance connection on the C phase between the main fuse clip and the
cubicle supply switch in the 4N cubicle.
The inspectors determined that replacing the upstream 175 Amp fuses on and restoring
power to the EDG ventilation MCC #1, which contained the charred 4N cubicle, without
identifying the source of the acrid odor could have reinitiated the fault and increased the
probability of a fire. In addition, operations personnel tried to locally close the damaged
switch which could have also re-initiated the fault. Entergy staff also did not take action
to remove or de-energize the charred cubicle after the condition was identified on
January 28, 2009. The damaged cubicle was de-energized and removed from the MCC
on February 11 in response to the inspectors questions.
Enclosure
12
This issue was reasonable for the licensee to foresee and correct because acrid odor is
an indication of a fault. It was reasonable for Entergy personnel to open panel doors
and perform visual inspections of the affected MCC prior to replacing upstream fuses
and restoring power to the fault. The inspectors determined that the National Electrical
Code NFPA 70E, Standard for Electrical Safety in the Workplace, prohibits
reenergizing a circuit after a protective device has operated until it has been determined
that the automatic operation was a result of an overload and not a fault. The acrid odor
in the EDG building was an indication of a fault vice an overload condition. In addition,
once Entergy personnel identified the cubicle was charred and experienced an electrical
fault, industry standards would have operators immediately secure power and/or
remove the damaged gear from the MCC.
Entergy entered the issue into the corrective action program as IP2-2009-00342 and
IP2-2009-00483, trained all operations personnel on the requirements to replace fuses
and re-energize electrical equipment, and plans to review operations procedures for
operating electrical equipment.
Analysis: The inspectors determined that Entergys failure to promptly identify an
adverse condition associated with damaged electrical components constituted a
performance deficiency. This issue was more than minor because the finding was
associated with the external factors attribute of the Initiating Events cornerstone and
impacted the cornerstone objective of limiting the likelihood of those events that upset
plant stability and challenge critical safety systems during shutdown as well as power
operations. Specifically, operations personnel did not identify the source of the acrid
odor, indicative of an electrical fault, in the EDG building; re-energized damaged
electrical equipment; and left damaged electrical components (cubicle 4N) energized for
14 days prior to its removal from the MCC. The inspectors determined these issues
increased the likelihood of a fire in the EDG building. The condition was evaluated by a
Senior Reactor Analyst utilizing Phase 2 of IMC 0609 Appendix F, Fire Protection
Significance Determination Process. It was determined that in the event of a fire
consuming the MCC, no transient would be placed on the plant and no components
required to safely shutdown the plant would be impacted. As a result, in accordance
with task 2.3.5 of Appendix F, the issue was screened to Green.
The inspectors determined that a cross-cutting aspect was associated with this finding
in the area of human performance related to conservative decision making. Specifically,
Entergys decision-making was non-conservative as it related to the processes used to
identify the source of the acrid odor; re-energize the damaged electrical equipment; and
keep a damaged electrical component energized for 14 days prior to its removal from
the MCC. (H.1(b) per IMC 0305)
Enforcement: 10 CFR 50 Appendix B, Criterion XVI, Corrective Action, requires that
measures shall be established to assure conditions adverse to quality, such as failures
and malfunctions are promptly identified and corrected. Contrary to the above, on
January 28, 2009, operations personnel did not identify that a safety-related bucket had
experienced a fault prior to replacing upstream fuses and restoring power to the bucket.
In addition, after replacing the upstream fuses, operations personnel tried to locally shut
the damaged cubicle switch and left damaged equipment energized until February 11,
2009. Entergy entered the issue into the corrective action program as IP2-2009-00342
and IP2-2009-00483, trained all operations personnel on the requirements to replace
fuses and re-energize electrical equipment, and plans to review operations procedures

for operating electrical equipment. Because the violation was of very low safety
significance and it was entered into the licensees corrective action program, this
violation is being treated as an NCV, consistent with the NRC Enforcement Policy: NCV 05000247/2009002-02, Failure to Identify Damaged Components in EDG
Ventilation Motor Control Center.
.2 Degraded Fire Door to the 480V Vital Bus Room
Introduction: The inspectors identified a NCV of very low safety significance (Green)
related to License Condition 2.K., fire protection program, because Entergy personnel
did not promptly identify and correct a degraded three-hour rated fire door on the west
entrance of the 480 Volt switchgear room.
Description: License Condition 2.K., fire protection program, requires that Entergy
implement and maintain in effect all provisions of the NRC-approved fire protection
program, as approved in part by the NRC Safety Evaluation Report (SER) dated
January 31, 1979. The January 31, 1979, SER requires administrative controls
comparable to those described in NRC Branch Technical Position 9.5-1, Guidelines for
Fire Protection for Nuclear Power Plants Docketed Prior to July 1, 1976. Branch
Technical Position (BTP) 9.5-1 requires that measures be established to assure that
conditions adverse to fire protection, such as deficiencies, deviations, defective
components, and non-conformities are promptly identified, reported, and corrected.
On February 6, 2009, the inspectors performed a fire protection walkdown of the 480-
Volt switchgear room. The inspectors noted the three-hour rated, swing-type fire door
on the west side of the 480-Volt switchgear room was not latched closed. The
inspectors observed the door being held open by the latch mechanism which had not
repositioned to allow the door to shut. The inspectors observed the latch mechanism
did not move freely preventing the door from shutting automatically. The inspectors
shut the door and notified shift operations personnel who tightened latch screws on the
door and wrote a condition report.
On February 18, the inspectors identified the 480-Volt switchgear room door was not
latched shut again. The inspectors determined the door could not be closed due to
interference from the latch mechanism screw which had backed out. The inspectors
notified operations of the fire door issue. Operations personnel re-inserted the latch
mechanism screw and documented the issue in a condition report. The inspectors
questioned whether it was appropriate to re-insert a screw that had backed out on its
own in such a short period of time. Entergy personnel subsequently inspected the door
on February 23 and identified the screws holding the latch mechanism to the door were
stripped. Entergy personnel tapped new holes in the door latch mechanism and
installed new screws.
On March 3, inspectors identified the 480-Volt switchgear room fire door not latched
shut again. The inspectors observed the door was being held open by the latch
mechanism which had not repositioned to allow the door to shut. The inspectors noted
the latch mechanism did not move freely preventing the door from shutting
automatically. The inspectors notified operations personnel of the non-functioning fire
door and Entergy subsequently had a locksmith inspect the latch. The locksmith
installed a new latch mechanism on March 3 and determined the latch issues observed
were age-related due to interaction of wear products from the latch interfering with the
moving portions of the latch, as a result of latching and unlatching door operations.
Enclosure
14
Entergy entered the issue into the corrective action program on March 3, performed an
inspection of all fire doors onsite, and identified and corrected issues with other required
fire doors.
Analysis: The inspectors identified a performance deficiency because Entergy personnel
did not identify and correct the non-functional fire door. The finding was more than
minor because it is associated with the protection against external factors attribute of
the Mitigating Systems cornerstone and affected the cornerstone objective of ensuring
the reliability of systems that respond to initiating events to prevent undesirable
consequences. Specifically, in the event of a large fire in the 480-Volt switchgear room
or the turbine building, the affected fire door is credited to prevent the spread of fire from
one area to the other area. This fire door, when degraded, impacts the reliability of
mitigating systems in the 480-Volt switchgear room that are relied upon during a large
fire in the turbine building, and vice versa.
This finding was evaluated using Phase 1 of IMC 0609 Appendix F, Fire Protection
Significance Determination Process. Since the area in question had a fire watch
posted during the time the door was degraded, an adequate level of protection was
maintained to compensate for the degraded door and resulted in the finding being of
very low safety significance. As such according to task 1.3.1, the inspectors determined
the finding was Green.
The inspectors determined that the finding had a cross-cutting aspect in the area of
problem identification and resolution because Entergy personnel did not thoroughly
evaluate a degraded fire door latch on several occasions, such that the resolution of the
problems addressed the causes. (P.1(c) per IMC 0305)
Enforcement: License Condition 2.K., fire protection program, requires that Entergy
implement and maintain in effect all provisions of the NRC-approved fire protection
program, as approved in part by the NRC Safety Evaluation Report (SER) dated
January 31, 1979. The January 31, 1979, SER requires administrative controls
comparable to those described in NRC Branch Technical Position 9.5-1, Guidelines for
Fire Protection for Nuclear Power Plants Docketed Prior to July 1, 1976. Branch
Technical Position 9.5-1 requires that measures be established to assure that conditions
adverse to fire protection, such as deficiencies, deviations, defective components, and
non-conformities are promptly identified, reported, and corrected.
Contrary to the above, Entergy personnel did not promptly identify and then
subsequently correct the non-functional 480-Volt switchgear fire door. This fire door
was identified by inspectors in a non-functional state on February 6, February 18, and
again on March 3, 2009. Entergy entered the issue into the corrective action program
as IP2-2009-00526, IP2-2009-00680, IP2-2009-00709, IP2-2009-00834, IP2-2009-
00842, and IP2-2009-00843. Because the violation was of very low safety significance
and it was entered into the licensees corrective action program, this violation is being
treated as an NCV, consistent with the NRC Enforcement Policy: NCV 05000247/2009002-03, Failure to Identify and Promptly Correct Degraded 480-Volt
Switchgear Room Fire Door.
1R07 Heat Sink Performance (71111.07A - 1 sample)
a. Inspection Scope
Enclosure
15
The inspectors selected the 22 component water heat exchanger for review to
determine the heat exchangers readiness and availability to perform its safety functions.
The inspectors reviewed the design basis for the component, reviewed Entergy
commitments to NRC Generic Letter 89-13, and reviewed engineering reports that
documented results of previous internal inspections. The inspectors also observed the
disassembly, inspection, and cleaning of the heat exchanger and reviewed engineering
results of the inspection to verify that appropriate corrective actions were initiated for
deficiencies that were discovered. The inspectors reviewed documents for and verified
that the amount of tubes plugged within the heat exchanger did not exceed the
maximum amount allowed. Documents reviewed are listed in the appendix.
b. Findings
No findings of significance were identified.
1R11 Licensed Operator Requalification Program
Quarterly Review (71111.11Q - 1 sample)
a. Inspection Scope
On February 23, 2009, the inspectors observed licensed operator simulator training
associated with a sustained loss of all alternating current (AC) power scenario, to verify
that operator performance was adequate, and that evaluators were identifying and
documenting crew performance problems. The inspectors evaluated the performance of
risk-significant operator actions, including the use of emergency operating procedures.
The inspectors assessed the clarity and effectiveness of communications, the
implementation of appropriate actions in response to alarms, the performance of timely
control board operation and manipulation, and the oversight and direction provided by
the control room supervisor. The inspectors also reviewed simulator fidelity with respect
to the actual plant. The inspectors evaluated licensed operator training for conformance
with the requirements of 10 CFR Part 55, Operator Licenses. The documents
reviewed during this inspection are listed in the Attachment. This observation of
operator simulator training represented one inspection sample.
b. Findings
No findings of significance were identified.
1R12 Maintenance Effectiveness (71111.12Q - 3 samples)
a. Inspection Scope
The inspectors reviewed performance-based problems that involved structures,
systems, and components (SSCs) to assess the effectiveness of maintenance activities.
When applicable, the reviews focused on:
- Proper Maintenance Rule scoping in accordance with 10 CFR 50.65;
- Characterization of reliability issues;
- Changing system and component unavailability;
Enclosure
16
- 10 CFR 50.65(a)(1) and (a)(2) classifications;
- Identifying and addressing common cause failures;
- Trending of system flow and temperature values;
- Appropriateness of performance criteria for SSCs classified (a)(2); and
- Adequacy of goals and corrective actions for SSCs classified (a)(1).
The inspectors also reviewed system health reports, maintenance backlogs, and
Maintenance Rule basis documents. The inspectors evaluated maintenance
effectiveness and monitoring activities against the requirements of 10 CFR 50.65. The
documents reviewed during this inspection are listed in the Attachment. The following
Maintenance Rule samples were reviewed and represented three inspection samples:
- RWST level indication system;
- EDG fuel injection system; and
- 480-Volt switchgear system.
b. Findings
Introduction: The inspectors identified a NCV of very low safety significance (Green)
related to TS 5.4.1, Administrative Controls: Procedures, because Entergy did not
maintain an adequate maintenance procedure for a safety-related electrical motor
control center (MCC). Specifically, the eight-year maintenance procedure for the
affected EDG ventilation MCC did not contain an adequate method to identify high
resistance connections within the cubicle.
Description: On January 28, 2009, operations personnel identified an acrid odor coming
from the EDG building. Subsequent personnel investigation revealed a charred cubicle
in a safety-related 480-Volt MCC. Specifically, cubicle 4N, in the EDG ventilation MCC,
experienced a phase-to-phase fault that caused the upstream 175 amp fuses to open
and de-energize the MCC. Entergy personnel subsequently generated a condition
report (CR) that was closed to a work request to troubleshoot and repair the cubicle.
Entergy personnel removed the damaged cubicle from the MCC on February 6 and
determined the likely cause to be a high-resistance connection between the cubicle
switch and 30 amp fuse clip on the C phase resulting in long-term overheating. This
overheating condition degraded the insulation between two of the three phases over
time and eventually resulted in a phase-to-phase fault on January 28, 2009.
The inspectors reviewed the 8-year maintenance procedure 2-MCC-003-ELC,
Klockner-Moeller, Series 200, 480 Volt Motor Control Center Preventive Maintenance,
which was performed on the affected EDG ventilation MCC on April 6, 2008. The
inspectors noted that the procedure was revised the same day to allow performance of
the maintenance without de-energizing the equipment. The revision resulted in portions
of the cubicle cleaning and inspection procedure not being performed because they
could not be safely performed while the cubicle was energized. The inspectors
determined that the procedure revision on April 6, 2008, was inappropriately treated as
an editorial revision without a technical evaluation of the change performed. In addition,
following interviews with Entergy personnel, it was determined that maintenance had not
been performed on this MCC prior to April 6, 2008.
Enclosure
17
The inspectors reviewed industry guidance for performing switchgear maintenance and
determined that Entergy did not include standard maintenance practices typically
utilized by its staff that would have identified a high resistance connection in the cubicle.
Specifically, continuity checks across contacts and switches were not performed, fuse
clip tensions and tightness were not performed, and all terminations could not be
checked due to the decision to perform the maintenance with portions of the cubicle
energized. In addition, the inspectors determined the EDG ventilation MCCs were not
included in Entergys thermography program, contrary to Entergy corporate preventive
maintenance templates. The inspectors determined that not performing thermography
on the EDG ventilation MCC constituted a missed opportunity to identify the high
resistance condition.
It is reasonable to consider the high resistance connection existed during the
maintenance performed on April 6, 2008, because high resistance connections do not
develop into phase-to-phase faults over a short period of time. This is an underlying
assumption for performing switchgear maintenance, which is intended to identify and
correct loose/high resistance connections, on an eight-year periodicity. In addition,
Entergys corporate template for switchgear maintenance recommends a six-year
periodicity and thermography every year. It is reasonable to expect Entergy to be aware
of the existing industry guidance as well as the Entergy corporate maintenance
templates.
Entergy entered the issue into the CAP as IP2-2009-00342 and IP2-2009-00483,
scoped the EDG ventilation MCC into the existing thermography program, performed an
extent-of-condition review that identified 21 additional panels that should be in the
thermography program, and plans to revise the maintenance procedure.
Analysis: The inspectors identified a performance deficiency because Entergy did not
maintain an adequate maintenance procedure for the safety-related EDG ventilation
MCC. This issue was more than minor because the finding was associated with the
external factors attribute of the Initiating Events cornerstone and impacted the initiating
events cornerstone objective of limiting the likelihood of those events that upset plant
stability and challenge critical safety systems during shutdown as well as power
operations. Specifically, the high resistance connection degraded into a phase-to-phase
fault and increased the likelihood of a fire in the EDG building. The condition was
evaluated by a Senior Reactor Analyst utilizing Phase 2 of IMC 0609 Appendix F, Fire
Protection Significance Determination Process. It was determined that in the event of a
fire consuming the MCC, no transient would be placed on the plant and no components
required to safely shutdown the plant would be impacted. As a result, in accordance
with task 2.3.5 of Appendix F, the issue was screened to Green.
The inspectors determined that the finding had a cross-cutting aspect associated with
the area of problem identification and resolution related to the use of operating
experience (OE). Specifically, Entergy personnel did not implement industry
recommended practices, or an alternate equivalent method, for identifying high
resistance connections in electrical switchgear. (P.2(b) per IMC 0305)
Enforcement. TS 5.4.1 Administrative Controls: Procedures, states, Written
procedures shall be established, implemented, and maintained covering the
requirements and recommendations of Appendix A of Regulatory Guide (RG) 1.33,
Revision 2. Appendix A of RG 1.33 requires procedures for maintenance activities that
Enclosure
18
can affect the performance of safety related equipment. Contrary to the above, Entergy
did not maintain a maintenance procedure for a safety-related MCC cubicle.
Specifically, the eight-year maintenance procedure, first performed on April 6, 2008, did
not contain an adequate method to identify and correct high resistance connections in
the cubicle. Entergy entered the issue into the CAP as IP2-2009-00342 and IP2-2009-
00483. Because the violation was of very low safety significance and it was entered into
the licensees corrective action program, this violation is being treated as an NCV,
consistent with the NRC Enforcement Policy: NCV 05000247/2009002-04, Inadequate
Maintenance Procedure for EDG Ventilation Motor Control Center.
1R13 Maintenance Risk Assessments and Emergent Work Control (71111.13 - 6 samples)
a. Inspection Scope
The inspectors reviewed scheduled and emergent maintenance activities to verify the
appropriate risk assessments were performed prior to removing equipment from service
for maintenance or repair. The inspectors verified that risk assessments were performed
as required by 10 CFR 50.65(a)(4) and were accurate and complete. When emergent
work was performed, the inspectors verified the plant risk was promptly reassessed and
managed. Documents reviewed during this inspection are listed in the Attachment. The
following activities represented six inspection samples:
maintenance outage;
- Planned risk during 21 auxiliary boiler feedwater (ABFW) pump outage and reactor
protection system testing;
- Unplanned elevated risk condition due to delayed work on reactor protection system
components during planned maintenance of 22 ABFW pump;
- Planned maintenance on a reactor water storage tank level indicator;
- Planned maintenance on the 22 ABFW pump while temporary modifications were
applied to the 21 and 23 ABFW pumps; and
- Planned risk during 23 EDG testing and maintenance.
b. Findings
Introduction: The inspectors identified a NCV of very low safety significance (Green)
related to 10 CFR 50.65(a)(4) because Entergy staff did not adequately assess the risk
associated with the unavailability of the Refueling Water Storage Tank (RWST) level
indication during planned maintenance on the level transmitters and instrumentation.
Description: On February 6, 2009, Entergy staff performed maintenance on the RWST
level indication system. The inspectors identified that the online risk assessment did not
consider planned maintenance on the RWST level indication, as required by 10 CFR
50.65(a)(4). The inspectors reviewed the work activity and noted the maintenance
scheduling software used by Entergy did not have the RWST maintenance coded as a
risk-significant activity. Entergys maintenance planning process prompts the
organization to evaluate the risk impact of all maintenance activities coded as risk-
significant. Therefore, a risk assessment was not performed for the quarterly RWST
level indication maintenance as required. In addition, the RWST level indication was not
represented in Entergys interactive risk model. Entergy staff subsequently updated the
risk model to include the RWST level indication and subsequently assessed the online
Enclosure
19
risk for the maintenance which resulted in a measurable increase in the core damage
frequency (CDF). The increase in CDF was not large enough to require entrance into
the higher risk category per Entergy procedures. In addition, the increase in CDF (1.1E-
6) combined with the limited duration of the maintenance (15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br />) resulted in a
relatively small incremental core damage probability deficit (1.9E-9).
The inspectors determined this same maintenance activity is modeled in the Indian Point
Unit 3 risk model. Entergy entered the issue into the corrective action program (CR-IP2-
2009-00342), updated the risk model to include the maintenance activity, assessed the
risk, and appropriately coded the maintenance activity to ensure it would be risk
assessed in the future.
Analysis: The inspectors identified a performance deficiency in that Entergy staff did not
assess the increase in plant risk resulting from planned maintenance activities on RWST
level instrumentation as required by 10 CFR 50.65(a)(4). The inspectors determined
that this finding was more than minor because it was a risk assessment issue in which
Entergy personnel did not consider risk significant SSCs that were unavailable during
maintenance. Specifically, RWST level indication is included in Table 2 of the plant
specific Phase 2 SDP risk-informed inspection notebook. The inspectors assessed the
significance of this issue in accordance with IMC 0609, Appendix K, Maintenance Risk
Assessment and Risk Management Significance Determination Process. The
inspectors determined that this finding was of very low safety significance (Green)
because the incremental core damage probability deficit was less than 1E-6.
The inspectors determined that the finding had a cross-cutting aspect in human
performance related work control. Specifically, Entergy personnel did not appropriately
plan work activities by incorporating risk insights for affected plant equipment. (H.3(a)
per IMC 0305)
Enforcement: 10 CFR 50.65 (a)(4) states, in part that licensees shall assess and
manage the increase in risk that may result from the proposed maintenance activities
before performing those activities. Contrary to the above, on February 6, 2009, Entergy
performed maintenance on the RWST level indication system without assessing the
increase in risk. Entergy entered the issue into the corrective action program (CR-IP2-
2009-00342. Because this issue is of very low safety significance and is entered into
Entergys corrective action program, this violation is being treated as an NCV consistent
the NRC Enforcement Policy: NCV 05000247/2009002-05, Failure to Include RWST
Level Maintenance In Online Risk Assessment.
1R15 Operability Evaluations (71111.15 - 7 samples)
a. Inspection Scope
The inspectors reviewed operability evaluations to assess the acceptability of the
evaluations, the use and control of compensatory measures when applicable, and
compliance with Technical Specifications. The inspectors reviews included verification
that operability determinations were performed in accordance with procedure
ENN-OP-104, Operability Determinations. The inspectors assessed the technical
adequacy of the evaluations to ensure consistency with the Technical Specifications,
UFSAR, and associated design basis documents. The documents reviewed are listed in
Enclosure
20
the Attachment. The following operability evaluations were reviewed and represented
seven inspection samples:
- Proximity of 480-Volt vital motor control center to an uninsulated steam line;
- Leakage from condensate storage tank (CST) return piping;
- Impacts of scaffolding built in the vicinity of the 21 and 22 component cooling water
heat exchangers;
- Impact on pressurizer surge line and reactor coolant system piping while performing
reactor plant startups and shutdowns due to thermal transients;
- Performance impact on the 21 and 22 auxiliary component cooling pumps (ACCPs)
with respect to a potential hydraulic lock-out condition of the 21 ACCP due to 22
ACCP larger impeller size;
- Mechanical failure of a grease fitting on 21 service water pump; and
- Low temperatures in condensate storage tank volume.
b. Findings
No findings of significance were identified. With respect to the CST return piping, the
inspectors determined Entergy operators maintained the CST aligned to supply water to
the AFW pumps. The inspectors concluded the leakage did not prevent the CST from
fulfilling its safety function. Specifically, design features of the CST and the elevation of
the return line relative to the leak location provided assurance that, in the event the CST
return line leak increased significantly, the CST water volume would have been
maintained above TS minimum required water level and able to supply the required
water to the auxiliary feedwater system.
1R18 Plant Modifications (71111.18 - 2 samples)
a. Inspection Scope
The inspectors reviewed one temporary plant modification package for securing
minimum flow lines on the motor driven auxiliary boiler feedwater pumps (ABFPs) and
controlling the operation on the ABFPs through a temporary operating procedure during
repairs of the CST return piping. The inspectors verified the design bases, licensing
bases, and performance capability of the system was not degraded by the temporary
modification. The inspectors review included Entergys engineering evaluation for
determining the ABFPs could start with the pumps required minimum flow being
achieved through the internal thrust balance lines while the minimum flow lines were
isolated. In addition, the inspectors interviewed plant staff, and reviewed issues entered
into the corrective action program to determine whether Entergy had been effective in
identifying and resolving problems associated with the temporary modification. The
documents reviewed are listed in the Attachment.
b. Findings
No findings of significance were identified.
Enclosure
21
.2 Permanent Modifications
a. Inspection Scope
The inspectors reviewed modification documents associated with the installation of an
additional nitrogen backup power supply for the 21- 24 steam generator atmospheric
dump valves. The inspector verified that the modification was reviewed adequately to
verify the modification conformed to design criteria and did not interfere or invalidate
previous design assumptions or functions. The documents reviewed are listed in the
Attachment.
b. Findings
No findings of significance were identified.
1R19 Post-Maintenance Testing (71111.19 - 6 samples)
a. Inspection Scope
The inspectors reviewed post-maintenance test procedures and associated testing
activities for selected risk-significant mitigating systems, and assessed whether the
effect of maintenance on plant systems was adequately addressed by control room and
engineering personnel. The inspectors verified that: test acceptance criteria were clear,
the test demonstrated operational readiness and were consistent with design basis
documentation; test instrumentation had current calibrations, and appropriate range and
accuracy for the application; and the tests were performed as written, with applicable
prerequisites satisfied. Upon completion of the tests, the inspectors verified that
equipment was returned to the proper alignment necessary to perform its safety function.
Post-maintenance testing was evaluated for conformance with the requirements of 10
CFR 50, Appendix B, Criterion XI, Test Control. The documents reviewed are listed in
the Attachment. The following post-maintenance activities were reviewed and
represented six inspection samples:
- Replacement of SG 23 pressure indicator PI-1355;
- 22 component cooling water heat exchanger following maintenance;
- 21 charging pump following recirculation valve maintenance;
- Condensate storage tank return line following pipe section replacement;
- Emergency diesel generator air compressor following quarterly maintenance; and
- 23 emergency diesel generator following quarterly engine maintenance.
b. Findings
No findings of significance were identified.
1R22 Surveillance Testing (71111.22 - 6 samples)
a. Inspection Scope
The inspectors observed performance of portions of surveillance tests and/or reviewed
test data for selected risk-significant SSCs to assess whether they satisfied Technical
Specifications, UFSAR, Technical Requirements Manual, and Entergy procedure
Enclosure
22
requirements. The inspectors verified that: test acceptance criteria were identified,
demonstrated operational readiness, and were consistent with design basis
documentation; test instrumentation had accurate calibration, and appropriate range and
accuracy for the application; and tests were performed as written, with applicable
prerequisites satisfied. Following the tests, the inspectors verified that the equipment
was capable of performing the required safety functions. The inspectors evaluated the
surveillance tests against the requirements in Technical Specifications. The documents
reviewed during this inspection are listed in the Attachment. The following surveillance
tests were reviewed and represented six inspection samples:
- 2-PT-Q031A, 21 Auxiliary Component Cooling Pump In-Service Test;
- 2-PT-Q054, Pressurizer Level Bistables;
- 2-PT-Q013 DS027, IST Valve Test of 888A (Safety Injection Pump Suction from
Residual Heat Removal heat Exchanger);
- 2-PT-2M4, Safety Injection System Train A Actuation Logic and Master Relay Test;
- 2-PT-Q030C, 23 Component Cooling Water Pump; and
- 0-SOP-LEAKRATE-001, RCS Leakrate Surveillance, Evaluation, and Leak
Identification.
b. Findings
Introduction. The inspectors identified a NCV of very low safety significance (Green)
related to 10 CFR 50.55a, Codes and standards, because Entergys procedure 2-PT-
Q031A did not contain appropriate acceptance criteria for determining that safety-
related check valves performed their safety function when required in accordance with
the American Society of Mechanical Engineers (ASME) OM Code.
Description. Entergy procedure 2-PT-Q031A, 21 Auxiliary Component Cooling Pump
(ACCP), is an In-Service Test (IST) procedure that demonstrates the operability of the
21 ACCP, the pump bypass line check valve (755), the 21 ACCP discharge check valve
(755B), and the 22 ACCP discharge check valve (755A) in accordance with Technical
Specification (TS) 5.5.6, Inservice Testing Program.
The test established a single acceptance criterion to determine if the discharge check
valve on the 22 ACCP train shuts when the parallel trains 21 ACCP is providing design
flow. The acceptance criterion was that no reverse rotation is observed on the 22
ACCP. Although NUREG-1482, Guidelines for Inservice Testing at Nuclear Power
Plants identifies the methodology of using reverse pump rotation as an acceptable
means of testing, Entergys site-specific experience in 2005 demonstrated this particular
method was not effective to maintain the ACCP discharge check valve safety function.
Specifically, when 2-PT-Q031A was performed on January 19, 2005, the 21 ACCP
failed the performance test because check valve 755A was determined to be in the
open position. However, the 22 ACCP did not rotate in the reverse direction. Following
disassembly of valve 755A, engineers determined the valve remained in the open
position because of excessive clearances between the hinge pin and hinge pin
bushings. Entergy personnel determined the check valve was likely in this condition
following maintenance on the valve in late 2004. CR-IP2-2005-0252 was written to
document and evaluate the issue. The issue was previously documented in LER 05000247/2005001-00 and NRC NCV 50-247/2005003-01. At that time, Entergy
personnel concluded the test criteria established in 2-PT-Q031A was acceptable but
that post-maintenance tests on the check valve should include amplifying comments
Enclosure
23
directing the performance of the IST following maintenance. Entergy personnel
concluded that the IST was adequate because the low pump head that caused the
pump performance test to fail led to troubleshooting that identified that check valve
755A was stuck open.
The inspectors determined that the criterion for determining operability of 755A in test 2-
PT-Q013A was inadequate because the criterion in the procedure previously failed to
identify that 755A remained in the open position in January 2005 and 2-PT-Q013A does
not identify any other criteria, including using pump head, to determine operability of
755A. Additionally, the inspectors determined the test criterion for check valve 755A
and 755B were not consistent with the following ASME Code requirements:
contain the Owner-specified reference values and acceptance criteria;
responsibility to ensure that the application, method, and capability of each
nonintrusive technique is qualified; and
shall be determined by exercising the valve while observing an appropriate
indicator.
Analysis. The inspectors determined that the performance deficiency was more than
minor because it was associated with the procedure quality attribute of the Mitigating
System cornerstone and adversely affected the cornerstone objective to ensure the
reliability of systems that respond to initiating events to prevent undesirable
consequences. Specifically, the test criterion used in procedure 2-PT-Q013A did not
ensure that valve 755A reliably performed its safety function when tested as
demonstrated by testing performed in January 2005. The inspectors determined that
the performance deficiency was of very low safety significance (Green) using IMC 0609,
Attachment 4, Phase 1 - Initial Screening and Characterization of Findings.
Specifically, the inspectors determined that this finding was of very low safety
significance because the finding did not result in a loss of safety function and did not
screen as potentially risk-significant due to external events initiating events.
The inspectors determined the finding had a cross-cutting aspect related to effective
corrective actions in the corrective action program component of the problem
identification and resolution area. Specifically, Entergy did not implement effective
corrective actions to resolve the testing inadequacy since 2005 during subsequent
quarterly testing. Additionally, the issue was considered to be indicative of current
performance because personnel when initially responding to inspector questions
concluded the acceptance criteria were adequate. (P.1(d) per IMC 0305)
Enforcement. 10 CFR 50.55a, Codes and standards, states that pumps and valves
which are classified as ASME code Class 1, Class 2, and Class 3 must meet the
inservice test requirements set forth in the ASME OM Code (2001 edition for Indian
Point Unit 2). Furthermore, inservice tests to verify operational readiness of pumps and
valves, whose function is required for safety must comply with the requirements of the
ASME OM Code. The ASME OM Code 2001 Subsection ISTC-1400 (c) states it is the
Owners responsibility to ensure that the application, method, and capability of each
nonintrusive technique is qualified. In addition, the ASME OM Code 2001 Subsection
ISTC-3530 states obturator movement shall be determined by exercising the valve
Enclosure
24
while observing an appropriate indicator. Contrary to the above, from February 2005
until February 2009, Entergy procedure 2-PT-Q031A, did not include appropriate
acceptance criteria for demonstrating operability of valve 755A. Specifically, the test did
not utilize a qualified technique for testing the check-valve and did not verify check valve
movement by observing an appropriate indicator. Because ACCP performance tests
since 2004 demonstrated satisfactory performance of the ACCPs at design flows, no
actual impact to the operability of the ACCPs was evident. Because this violation was
of very low safety significance and it was entered into Entergys corrective action
program (IP2-2009-1312), this violation is being treated as an NCV, consistent with the
NRC Enforcement Policy. NCV 2009002-06, Inadequate Test Acceptance Criteria
for Auxiliary Component Cooling Check Valves.
Cornerstone: Emergency Preparedness (EP)
1EP6 Drill Evaluation (71114.06 - 1 sample)
a. Inspection Scope
The inspectors evaluated an emergency classification conducted on February 23, 2009,
during a licensed-operator requalification simulator training evaluation. The inspectors
observed an operating crew in the simulator respond to various, simulated initiating
events that ultimately resulted in the simulated implementation of the emergency plan.
In particular, the inspectors verified the adequacy and accuracy of the simulated
emergency classification of a Site Area Emergency. While other simulated
classifications were made, the inspectors verified that the initial classification was
appropriately credited as an opportunity toward NRC performance indicator data. The
inspectors observed the management evaluator and training critique following
termination of the scenarios, and verified that significant performance deficiencies were
appropriately identified and addressed within the critique and the corrective action
program. Also, the inspectors reviewed the summary performance report for the
evaluation and verified that appropriate attributes of drill performance including
deficiencies were captured. This evaluation constituted one inspection sample.
b. Findings
No findings of significance were identified.
2. RADIATION SAFETY
Cornerstone: Occupational Radiation Safety (OS)
2OS1 Access Control to Radiologically Significant Areas (71121.01 - 16 samples)
a. Inspection Scope
From March 23 through March 27, 2009, the inspectors conducted the following
activities to verify that Entergy was properly implementing physical, engineering, and
administrative controls for access to high radiation areas, and other radiologically
controlled areas, and that workers were adhering to these controls when working in
these areas. Implementation of the access control program was reviewed against the
Enclosure
25
criteria contained in 10 CFR 20, site technical specifications, and Entergys procedures
required by the Technical Specifications as criteria for determining compliance.
This inspection activity represents completion of sixteen (16) samples relative to this
inspection area. The inspector performed independent radiation dose rate
measurements and reviewed the following items:
Plant Walk Downs and Radiological Work Permit Reviews
(1) Exposure significant work areas were identified by inspectors for review within
radiation areas, high radiation areas, and airborne areas in the plant. Associated
licensee controls and surveys were review for adequacy. Work reviewed
included: Refuel Floor Split Pin and Reactor Head Inspections, Refuel Floor
Lower Internals Removal and Installation, Refuel Floor and Fuel Support Building
Fuel Transport Equipment Repairs requiring an underwater diver, Reactor
Coolant Pump work including RCP #31 Impeller replacement, Containment valve
work including Pressurizer Safety Valves, Various Containment and Auxiliary
Building activities.
(2) With a survey instrument and assistance from a health physics technician,
inspectors walked down the above mentioned areas to determine: whether the
radiation work permits (RWPs), procedures and engineering controls were in
place and whether surveys and postings were adequate.
(3) The inspectors reviewed RWPs that provide access to exposure significant areas
of the plant including high radiation areas. Specified electronic personal
dosimeter alarm set points were reviewed with respect to current radiological
condition applicability and workers were queried to verify their understanding of
plant procedures governing alarm response and knowledge of radiological
conditions in their work area.
(4) There were no radiation work permits for airborne radioactivity areas with the
potential for individual worker internal exposures of >50 mrem CEDE.
(5) There were no internal dose assessments that resulted in actual internal
exposures greater than 50 mrem CEDE. Internal assessments were reviewed to
determine adequacy and assurance that they were not in fact equal to or greater
than 50 mrem CEDE.
Problem Identification and Resolution
(6) Access controls related condition reports were reviewed since the last inspection
in this area. Staff members were interviewed and documents reviewed to
determine that follow-up activities are being conducted in an effective and timely
manner, commensurate with their safety and risk.
(7) For repetitive deficiencies or significant individual deficiencies in problem
identification and resolution, the inspectors determined if the licensees
assessment activities were also identifying and addressing these deficiencies.
(8) A review of events revealed no performance indicator occurrences that involved
dose rates greater than 25 Rem/hour at 30 cm, dose rates greater than
Enclosure
26
500 Rem/hour at 1 meter, or unintended exposures greater than 100 mrem
TEDE (or greater than 5 Rem SDE or greater than 1.5 Rem LDE)
Job-in-Progress Reviews
(9) The inspectors observed aspects of various on-going activities to confirm that
radiological controls, such as required surveys, area postings, job coverage, and
job site preparations were conducted. The inspectors verified that personnel
dosimetry was properly worn and that workers were knowledgeable of work area
conditions. The inspectors attended pre-planning meetings for work described
earlier in the report.
(10) Underwater diving activities associated with repairs to the fuel transport system
were reviewed for adequacy. Dosimetry requirements, bioassay requirements,
and controls were reviewed.
High Risk Significant, High Dose Rate High Radiation Areas (HRA) and Very HRA
Controls
(11) Keys to locked and very HRA were reviewed for their controls and proper
inventory. Accessible locked HRA were verified to be properly secured and
posted during plant tours.
(12) The inspectors discussed with Radiation Protection supervision the adequacy of
high dose rate HRA controls and procedures and verified that no programmatic
or procedural changes have occurred that reduce the effectiveness and level of
worker protection.

b. Findings
Introduction. The inspectors identified a NCV of very low safety significance (Green)
related to Technical Specification 5.4.1.a, Procedures, because Entergy personnel did
not generate condition reports or investigation paperwork for multiple high dose-rate
alarms as required by station procedures. Specifically, personnel did not generate the
required condition reports and adequately document the investigations for six instances
of unplanned or un-briefed electronic dosimeter alarms received by individuals in the
Unit 2 radiologically controlled area (RCA) that occurred between January 2009 and
March 2009.
Description. During the period January 2009 through March 2009, six instances of
electronic dosimeter dose rate alarms were recorded by the access control system for
Unit 2 personnel in the RCA (Unit 3 had 15 instances). During this period, Entergy
personnel inconsistently utilized an informal process of reviewing the alarms without a
full investigation or approval process. Moreover, in one of the six instances at Unit 2,
the inspectors identified that no investigation or follow-up had occurred. In some cases,
the occurrences were over two months old, which the inspectors noted would have
made resultant investigations more challenging to perform. In other cases, the alarms
were not identified until the worker attempted to re-enter the RCA and the access control
system required manual override to un-lock the occurrence to allow entry into the RCA.
The inspectors noted that the controlling Entergy procedure for this activity, EN-RP-203,
Dose Assessment, specifies that for a dose-rate alarm that is unanticipated or un-
briefed, several actions are required, one of which is to initiate a condition report,
another is to document the investigation using an attachment in the procedure. Contrary
to EN-RP-203, for these 21 instances, no condition reports or attachments were
generated with a detailed investigation prior to the workers re-entering the radiologically
controlled area. The highest exposure received by these workers during their entry, as
indicated by their electronic dosimeter and logged by the access control system, was 33
mRem, while most dosimeters indicated less than 1 mRem for the entry.
Analysis. The inspectors determined that the failure to generate a condition report, as
well as the failure to adequately investigate six unplanned or un-briefed electronic
dosimeter alarms prior to re-entry into the Unit 2 RCA, as required by station procedure
was a performance deficiency. This performance deficiency was within Entergy
personnels ability to foresee and correct, and should have been prevented. This issue
was not subject to traditional enforcement, in that it did not have actual safety
consequence, it was not an issue that had the potential to impact NRCs ability to
perform its regulatory function, and there were no willful aspects.
The finding is more than minor because it is associated with the Occupational Radiation
Safety cornerstone attribute of programs and process, and adversely affected its
objective to ensure adequate protection of worker health and safety from exposure to
radiation. Moreover, the inspectors identified a programmatic deficiency to maintain and
implement programs to keep exposures as low as reasonably achievable, because
multiple examples were identified regarding the failure to satisfy station radiation
protection procedures. Specifically, in six cases, Entergy did not fully evaluate dose rate
alarms received by workers in radiologically controlled areas of the plant. Using the
Occupational Radiation Safety Significance Determination Process, the inspectors
determined that the finding was of very low safety significance (Green) because it did not
involve: (1) as low as is reasonably achievable planning and controls, (2) an
Enclosure
28
overexposure, (3) a substantial potential for overexposure, or (4) an impaired ability to
assess dose.
The inspectors determined that the finding had a cross-cutting aspect related to
procedural adherence in the Work Practices component of the Human Performance
area. Specifically, Entergy employees did not follow procedures to generate condition
reports and document investigations when high-dose rate alarms were received by
workers. (H.4 (b) per IMC 0305)
Enforcement. Technical Specification 5.4.1.a, Procedures, requires that Entergy
establish, implement, and maintain procedures specified in Regulatory Guide (RG) 1.33,
Revision 2, Appendix A., Section 7.e, radiation protection procedures for personnel
monitoring. Entergy procedure EN-RP-203, Revision 2, Section 5.11, requires that a
condition report be written for each unplanned or un-briefed electronic dosimeter dose-
rate alarm. Contrary to the above, the inspectors identified through a review of
electronic dosimeter log information from January 2009 through March 2009, six
instances of unanticipated or un-briefed electronic dosimeter dose-rate alarms when the
procedure was not implemented and condition reports were not generated. Because
this finding was of very low safety significance and it was entered into the corrective
action program as CR-IP3-2009-001253 and CR-IP3-2009-001318, this violation is
being treated as an NCV, consistent with the NRC Enforcement Policy. NCV 05000247/2009002-07, Failure to Follow Radiation Protection Procedures.
2OS2 ALARA Planning and Controls (71121.02 - 12 samples)
a. Inspection Scope
From March 23 through March 27, 2009, the inspectors conducted the following
activities to verify that Entergy was properly maintaining individual and collective
radiation exposures as low as is reasonably achievable (ALARA). Implementation of the
ALARA program was reviewed by inspectors against the criteria contained in 10 CFR
20, applicable industry standards, and Entergys procedures.
This inspection activity represents completion of twelve (12) samples relative to this
inspection area.
Inspection Planning
(1) The inspectors reviewed pertinent information regarding cumulative exposure
history, current exposure trends, and on-going activities to assess current
performance and outage exposure challenges. The inspectors determined the
sites 3-year rolling collective average exposure.
(2) The inspectors reviewed unit 3 outage work related activities occurring during the
inspection period, the associated ALARA plans, RWPs, ALARA Committee
Reviews, exposure estimates, actual exposures and post job reviews. Work
reviewed included: Refuel Floor Split Pin and Reactor Head Inspections, Refuel
Floor Lower Internals Removal and Installation, Refuel Floor and Fuel Support
Building Fuel Transport Equipment Repairs requiring an underwater diver,
Reactor Coolant Pump work including RCP #31 Impeller replacement,
Enclosure
29
Containment valve work including Pressurizer Safety Valves, Various
Containment and Auxiliary Building activities.
(3) The inspectors reviewed implementing procedures associated with maintaining
occupational exposures ALARA. This included a review of the processes used to
estimate and track work activity exposures.
Radiological Work Planning
(4) With respect to the work activities listed above, the inspectors reviewed dose
summary reports, related post-job ALARA reviews, related RWPS, exposure
estimates and actual exposures, and ALARA Committee meeting paperwork.
Through this review, the inspector determined that dose was appropriately
managed and evaluated by Station Management.
(5) ALARA work activity evaluations, exposure estimates, and exposure mitigating
requirements were reviewed for work packages previously mentioned. The
inspectors determined that Entergy established procedures, engineering and
work controls, based on sound radiation protection principles.
(6) The inspectors compared the results achieved with the intended dose that was
established in the planning of the work. The inspectors determined the reasons
for any inconsistencies between the intended and actual work activity doses and
station management awareness and involvement.
(7) The inspectors evaluated for adequacy, the interfaces between operations,
radiation protection, maintenance, maintenance planning and others for interface
problems or missing program elements.
Verification of Dose Estimates and Exposure Tracking Systems
(8) Methods for adjusting exposure estimates, or re-planning work, when
unexpected changes in scope or emergent work is encountered, was reviewed
by the inspectors for adequacy.
Job Site Inspections and ALARA Controls
(9) The inspectors reviewed work activities that present the highest radiological risk
to workers. The inspectors evaluated Entergys use of engineering controls to
achieve dose reductions and to verify that procedures and controls are consistent
with ALARA reviews. Associated ALARA Plans and RWPs were reviewed to
determine if appropriate exposure and contamination controls were being
employed.
Radiation Worker Performance
(10) Through observations and interviews, workers and technicians were found to be
knowledgeable of the work area radiological conditions and low dose waiting
areas.
Enclosure
30
Declared Pregnant Workers
(11) The inspectors reviewed information associated with declared pregnant workers
during the assessment period and whether appropriate monitoring and controls
were being utilized to ensure compliance with 10CFR Part 20.
Problem Identification and Resolution
(12) The inspectors reviewed elements of the Entergys corrective action program
related to implementing radiological controls to determine if problems are being
entered into the program for timely resolution.
b. Findings
No findings of significance were identified.

4OA2 Identification and Resolution of Problems (71152)
.1 Routine Problem Identification & Resolution Program Review
a. Inspection Scope
As required by Inspection Procedure 71152, Identification and Resolution of Problems,
and to identify repetitive equipment failures or specific human performance issues for
follow-up, the inspectors performed a daily screening of all items entered into Entergys
corrective action program. The review was accomplished by accessing Entergys
computerized database for condition reports, and attending condition report screening
meetings.
In accordance with the baseline inspection modules, the inspectors selected corrective
action program items across the Initiating Events, Mitigating Systems, and Barrier
Integrity cornerstones for further follow-up and review. The inspectors assessed
Entergys threshold for problem identification, adequacy of the causal analysis, extent of
condition reviews, and operability determinations, and timeliness of the associated
corrective actions. The condition reports reviewed during this inspection are listed in the
Attachment.
b. Findings
No findings of significance were identified
4OA3 Event Followup
.1 Condensate Return Line Leak on February 15, 2009
a. Inspection Scope
On February 15, 2009, an operator observed indications of wetness in a pipe sleeve in
the floor of the auxiliary feed pump building. The operator notified the control room.
Chemistry samples of the water were drawn and analyzed. On February 16, Entergy
determined the chemistry results indicated the water was from the condensate storage
tank (CST) return line. The inspectors reviewed the technical specifications (TS) to
determine whether operators entered the applicable TS action statements for the CST
and completed required actions to administratively determine the back-up on-site city
water tank was available, if needed, to provide water to the auxiliary feedwater pumps.
The inspectors reviewed Entergys operability evaluation of the CST to determine
whether it was technically supported. In addition, the inspectors reviewed the impact of
the leak on the auxiliary feed water system which utilizes the CST as a primary source of
water and circulates water back to the CST through the CST return piping. The
inspectors also reviewed chemistry and radiological samples taken of the water to assess
the environmental impact of the leak and determine if the release was below NRC
regulatory limits for liquid effluents.
Enclosure
32
b. Findings and Observations
No findings of significance were identified.
Entergy excavated a portion of the CST piping in the area of the identified leakage and
determined that the CST return pipe was leaking due to a hole the pipe where a small
area of a protective coating was missing. Entergy also identified two additional areas of
piping with metal loss that did not exceed ASME Code minimum required wall thickness.
However, the areas were repaired while the opportunity existed. Entergy removed the
portion of pipe with the localized defects and sent the specimen to a laboratory for
analysis to identify the causes. The inspectors determined that the actions Entergy
implemented to evaluate and repair the leaking CST pipe to restore operability to the
CST were adequate and in accordance with their operating license. Additionally, the
inspectors determined that the evaluations and actions Entergy performed to evaluate
and maintain operability of the auxiliary feed pumps were adequate. Entergy analyzed
the water leaking up through the sleeve and determined it was CST water based on
hydrazine and tritium levels. The amount of tritium detected in the water was consistent
with that found in the CST, for example, analyses of samples of water from the leak
returned 2000 - 2300 picocuries per liter (pCi/l). The release was determined to be
below the NRC regulatory limits for liquid effluents. For added perspective, while not
drinking water, the Environmental Protection Agency environmental limit for drinking
water requires tritium levels less than 20,000 pCi/l.
Entergy initiated a root cause analysis to determine causes of the leak that is scheduled
to be completed in May 2009. At the end of the inspection period, the inspectors were
monitoring the performance of Entergy in implementing its corrective action program to
address the issue and develop a root cause evaluation and further corrective actions.
4OA5 Other Activities
.1 Continued Groundwater Sampling Effort to Monitor Tritium (Deviation Memorandum
Inspection)
a. Inspection Scope
During the week of March 23-27, 2009, the inspectors met with Entergy representatives
to review the results of recent groundwater samples, as well as those taken and
analyzed in 2008. The review was conducted against criteria contained in 10CFR20,
10CFR50, and applicable industry standards.
The review of the data included a comparison of Entergys data with split samples taken
by the NRC of monitoring wells MW-66 and MW-67, as well as the LaFarge sample
point. In all, 47 samples were analyzed and compared from January 2008 through
January 2009. Isotopic analyses were performed and compared at each of the sample
points for: Tritium, Strontium 90, Nickel 63, and gamma emitters such as Cobalt-60 and
Cesium-137. Results of the NRC samples can be found in ADAMS accession numbers:
ML081420676, ML082690244, ML082690202, ML082690237, ML082730830,

and CR-IP2-2009-01114.
b. Findings
No findings of significance were identified.
The inspectors concluded that overall, there was agreement between Entergy
personnels results and those independently analyzed by the NRC, and that actions
taken by Entergy have been appropriate. The inspectors also noted that conservative
estimates indicate that the samples represent a very small fraction of the permissible
public dose limits and are negligible with respect to natural background radiation levels.
.2 Quarterly Resident Inspector Observations of Security Personnel and Activities
a. Inspection Scope
During the inspection period, the inspectors conducted observations of security force
personnel and activities to ensure that these activities were consistent with Entergy
security procedures and applicable regulatory requirements. Although these
observations did not constitute additional inspection samples, the inspections were
considered an integral part of the normal, resident inspector plant status reviews during
implementation of the baseline inspection program.
b. Findings
No findings of significance were identified.
4OA6 Meetings
Exit Meeting Summary
On April 15, 2009, the inspectors presented the inspection results to Joe Pollock and
other Entergy staff members, who acknowledged the inspection results presented.
