SUBJECT: BRAIDWOOD STATION, UNITS 1 AND 2 NRC INTEGRATED INSPECTION REPORT 05000456/2008003; 05000457/2008003
Dear Mr. Pardee:
On June 30, 2008, the U.S. Nuclear Regulatory Commission (NRC) completed an integrated inspection at your Braidwood Station, Units 1 and 2. The enclosed report documents the inspection results, which were discussed on July 9, 2008, with Mr. B. Hanson and other members of your staff. The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel. Based on the results of this inspection, four NRC-identified findings of very low safety significance (Green) were identified. The findings were also determined to involve violations of NRC requirements. However, because of their very low safety significance and because the issues were entered into your corrective action program, the NRC is treating the issues as a Non-Cited Violations, in accordance with Section VI.A.1 of the NRC=s Enforcement Policy. If you contest the subject or severity of a Non-Cited Violation, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001, with a copy to the Regional Administrator, U.S. Nuclear Regulatory Commission - Region III, 2443 Warrenville Road, Suite 210, Lisle, IL 60532-4352; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the Resident Inspector Office at the Braidwood Station. In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be made available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

GS IR 05000456/2008003, 05000457/2008003; 04/01/2008 - 06/30/2008; Braidwood Station, Units 1 & 2; Adverse Weather Protection, Flooding, Radioactive Material Processing and Transportation, and Other Activities. This report covers a three-month period of inspection by resident inspectors and announced baseline inspections by regional inspectors. Four Green findings were identified by the
inspectors. The findings were considered Non-Cited Violations (NCVs) of
- NRC regulations. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (
- NRC management review. The Nuclear Regulatory Commission's (NRC's) program for overseeing the safe operation of commercial nuclear power reactors is described in
NRC-Identified and Self-Revealed Findings Cornerstone: Initiating Events * Green. The inspectors identified a performance deficiency involving a NCV of Technical Specifications 5.4.1, related to the unauthorized and improper storage of loose material in the designated material exclusion area around the Unit 1 and Unit 2 transformers. The inspectors identified this issue on a number of occasions. After each occurrence, the licensee took immediate corrective actions by either removing loose material out of
the transformer yard or properly securing the material being stored in the transformer yards. The inspectors concluded that the finding was more than minor because loose/unsecured material in the transformer yards increased the likelihood of those events occurring that could upset plant stability. Specifically, during high wind speed
conditions the loose material could have affected the main power transformers and could have caused a unit trip or it could have affected the station auxiliary transformers that could increase the likelihood of a loss of mitigating systems. In each case however, the inspectors concluded that there was not enough debris in either area to affect both transformers simultaneously. The finding was determined to be of very low safety
significance because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigating equipment or functions would not be available. The primary cause of this NCV was related to the cross-cutting aspect in the area of Human Performance in the Work Practices component (Item H.4.(b)). Multiple groups, including contractors and operators failed to properly implement the procedures for control of
material in the transformer exclusion zones. The preliminary cause appeared to be inadequate supervisory and management oversight of work activities. (Section 1R01.2) * Green. The inspectors identified a performance deficiency involving a
CFR), Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," related to a plant barrier impairment (PBI) procedure. The procedure for PBI did not contain steps to ensure that relied-upon compensatory measures were maintained. Specifically, while the B Train room of
essential service water had a flood barrier removed and covered under a PBI, the compensatory measure of sump alarms were found not functioning. The licensee has
Enclosure entered the issue into their corrective action program, repaired the sump alarms, and plans to revise the
- PBI [[procedure. The inspectors concluded that the finding was greater than minor because the licensee failed to effectively manage prescribed compensatory measures related to a cornerstone objective. The finding was determined to be of very low safety significance based on a]]
SDP Phase 1 screening in accordance with IMC 0609, Table 4a, because the finding did
not increase the likelihood of an external or internal flood. The primary cause of this
- NCV was related to the cross-cutting component of Human Performance for Resources (Item H.2.(c)) because the licensee's
- PBI [[procedure was not adequate in that it did not ensure safety margins were maintained by providing instructions to periodically verify that the compensatory measures were still available. (Section 1R06) Cornerstone: Mitigating Systems * Green. The inspectors identified a performance deficiency involving a]]
- NCV [[of Technical Specifications 5.4.1, for the licensee's failure to provide procedural controls for the unique identification of Regulatory Guide 1.97 post-accident instrumentation to aid the control room operator. Specifically, the licensee failed to adequately control the labeling on both units' control panels and the simulator, resulting in several improperly marked post-accident indicators. The licensee has entered the issue into their corrective action program and labeled the appropriate post-accident instruments. The finding was greater than minor because, if left uncorrected, it could become a more significant safety concern. Inaccurately labeled control room indicators of post-accident instrumentation could lead to confusion and hamper operator response if conflicting indications resulted due to accident conditions. The finding was determined to be of very low safety significance based on a]]
SDP Phase 1 screening in accordance with IMC 0609.04, "Initial Screening and Characterization of Findings." The inspectors did
not identify a cross-cutting aspect to this finding. (Section
- 4OA 5.3) Cornerstone: Public Radiation Safety * Green. A finding of very low safety significance and associated
NCV of the Technical Requirements Manual, Appendix L, and Technical Specifications 5.4.1(a) were identified by the inspectors. On May 1, 2008, the inspectors identified that the licensee had failed to sample the temporary wastewater storage tanks installed to hold shower and wash water from the Unit 2 Containment Access Facility at the required frequency of seven
days. Procedure
BR-654, "Unit 1(2) Containment Access Facility Liquid and Air Sampling and Disposal Requirements, Revision 0," as written, did not direct the required sampling frequency. The licensee took immediate corrective action by sampling the temporary storage tank, revising the scheduling tool to ensure that the tanks are sampled at least every seven days when radioactive material is being added to the tank,
and planning to revise the sampling procedure. The finding involved an occurrence in the licensee's radioactive material control program that is contrary to the licensee's procedures. The finding was more than minor because it impacted the program and process attribute of the Public Radiation Safety Cornerstone and affected the cornerstone objective to ensure adequate protection of public health and safety from exposure to radioactive material release into the public
domain, in that the failure to measure the levels of radioactivity in the temporary storage
Enclosure tanks had the potential to impact the licensee's effluent program. The inspectors applied the
- IMC [[0609, Appendix D, "Public Radiation Safety Significance Determination Process" to this finding. The finding is in the licensee's radiological effluent monitoring program. The finding did not involve a failure to implement the effluent release program nor did public dose exceed Appendix I, Criterion, or 10]]
CFR 20.1302(e) and the finding was determined to be of very low safety significance. The primary cause of this
- H. 4.(c)) because the licensee did not ensure that supervisory and management oversight of the procedure was adequate to assure nuclear safety. (Section 2
PS2.1) B. Licensee-Identified Violations No violations of significance were identified.

DETAILS Summary of Plant Status Unit 1 operated at or near full power for the entire inspection period. Unit 2 operated at or near full power until about April 15, 2008, when a gradual power coast down was started toward a refueling outage. The unit was brought from 95 percent of full power to 80 percent on April 17 for main steam relief valve testing and then back to 92 percent of full
power on April 18. The unit continued to coast down until being shutdown from 90 percent power on April 20, 2008, for the refueling. The unit was made critical at the end of the outage on May 16, 2008, the generator was placed on line on May 17, 2008, and the power was gradually increased, reaching full power on May 25, 2008. The unit operated at or near full power for the remainder of the inspection period. 1.
SAFETY Cornerstone: Initiating Events, Mitigating Systems, and Barrier Integrity 1R01 Adverse Weather Protection (71111.01) .1 Summer Readiness of Offsite and Alternating Current Power Systems a. Inspection Scope The inspectors verified that plant features and procedures for operation and continued availability of offsite and alternating current (AC) power systems during adverse weather
were appropriate. The inspectors reviewed the licensee's procedures affecting these areas and the communications protocols between the transmission system operator (TSO) and the plant to verify that the appropriate information was being exchanged when issues arose that could impact the offsite power system. Examples of aspects considered in the inspectors' review included: * coordination between the
- TSO and the plant during off-normal or emergency events; * explanations for the events; * estimates of when the offsite power system would be returned to a normal state; and * notifications from the
- TSO to the plant when the offsite power system was returned to normal. The inspectors also verified that plant procedures addressed measures to monitor and maintain availability and reliability of both the offsite
AC power system prior to or during adverse weather conditions. Specifically, the inspectors verified that the procedures addressed the following: * the actions to be taken when notified by the TSO that the post-trip voltage of the offsite power system at the plant would not be acceptable to assure the continued operation of the safety-related loads without transferring to the onsite power supply;
Enclosure * the compensatory actions identified to be performed if it would not be possible to predict the post-trip voltage at the plant for the current grid conditions; * a re-assessment of plant risk based on maintenance activities which could affect grid reliability, or the ability of the transmission system to provide offsite power; and * the communications between the plant and the
- TSO [[when changes at the plant could impact the transmission system, or when the capability of the transmission system to provide adequate offsite power was challenged. Documents reviewed were listed in the Attachment. The inspectors also reviewed corrective action program (]]
- CAP ) items to verify that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into their
- CAP in accordance with station corrective action procedures. This inspection constituted one readiness of offsite and alternate
- AC [[power systems sample as defined in Inspection Procedure (IP) 71111.01-05. b. Findings No findings of significance were identified. .2 Readiness for Summer Seasonal Extreme Weather Conditions a. Inspection Scope The inspectors performed a review of the licensee's preparations for summer weather for selected systems, including conditions that could lead to an extended drought as a result of high temperatures. During the inspection, the inspectors focused on plant specific design features and the licensee's procedures used to mitigate or respond to adverse weather conditions. Additionally, the inspectors reviewed the Updated Final Safety Analysis Report (UFSAR) and performance requirements for systems selected for inspection, and verified that operator actions were appropriate as specified by plant specific procedures. The inspectors also reviewed]]
- CAP items to verify that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into their
CAP in accordance with station corrective action procedures. Documents reviewed were listed
in the Attachment. The inspectors' reviews focused specifically on the following plant systems: * cooling water lake (ultimate heat sink); * transformer yard; and * turbine oil system. This inspection constituted one seasonal adverse weather sample as defined in
NCV) of Technical Specifications (TS) 5.4.1.a having very low safety significance (Green) for unauthorized
Enclosure and improper storage of unsecured material in the designated material exclusion area around the Units 1 and 2 transformers. Description: On April 30, 2008, the inspectors identified three metal scaffold poles and a large floor rug in the exclusion area of the Unit 1 transformer yard. The inspectors notified the shift manager who immediately had the material removed and entered the issue into the
IR) 770357. The Shift Manager indicated that he
had not given permission, as required by Procedure
AA-716-026, "Station Housekeeping/Material Condition Program," for the material to be in the exclusion area. On May 22, 2008, the inspectors identified four metal stanchions and associated garden hoses staged, two each, in the Units 1 and 2 transformer yards. The material had been staged as a contingency for providing supplemental cooling to the main power
transformers as a summer readiness action, but the material was not secured. Although the staging had the permission of the Shift Manager, it was not done in accordance with the applicable Procedure, BwOP MP-26, "Supplemental Main Power Transformer Cooling," which required that all hoses in the transformer area be properly secured to prevent the hoses from becoming wind-generated hazards that may cause a loss of offsite power. The inspectors notified the Work Execution Center Supervisor who immediately had the material properly secured with sandbags and entered the issue into
the
IR 778589. On May 28, 2008, the Illinois Department of Emergency Management (IEMA) inspector identified a metal stanchion with a radiation warning sign in the Unit 2 transformer yard. The sign had apparently been removed from the turbine building during floor refinishing and placed in the transformer yard without the permission of the Shift Manager as
required by Procedure
- IEMA inspector notified the Work Execution Center Supervisor who immediately had the material removed and entered the issue into the
CAP as IR 780318. On May 29, 2008, the inspectors identified two pieces of a metal door threshold in the exclusion area of the Unit 2 transformers. The material was brought to the attention of
an operations supervisor who immediately removed the material and entered the issue into the
IR 780777. The inspectors noted that this instance, as well as some of the previously mentioned ones, was probably the result of contractors working on turbine building floor refinishing, and clearing material off the floor by putting it through the turbine building door into the exclusion area. The inspectors noted that there were
multiple information signs explaining the exclusion area rules on most of the entry paths into the exclusion areas except that there were no signs on the doors from the turbine building directly into the areas. This observation was also entered into the licensee's
IR 780777. Analysis: The inspectors determined that the identification of multiple examples of improperly placing unsecured material in the transformer yard exclusion zones was a performance deficiency warranting a significance evaluation. The finding was more than minor because it involved the external factors attribute of the Initiating Events cornerstone and affected the cornerstone objective of limiting the likelihood of those events that could upset plant stability. The inspectors applied the Phase 1 Screening Worksheet of the Significance Determination Process (SDP) and determined that the issue screened out as a Green finding because it did not contribute to both the likelihood
of a reactor trip and the likelihood that mitigating equipment or functions would not be
Enclosure available. The material in the transformer yards could have affected the main power transformers and caused a unit trip, or it could have affected the station auxiliary transformers and increased the likelihood of a loss of mitigating systems, but it was not reasonable that it was enough material to affect both simultaneously. The finding had a cross-cutting aspect in the area of Human Performance in the Work Practices component (H.4.(b)). Multiple groups, including contractors and operators failed to
properly implement the procedures for control of material in the transformer exclusion zones. The preliminary cause appeared to be inadequate supervisory and management oversight of work activities. Enforcement: Technical Specification 5.4.1.a stated that written procedures shall be established, implemented, and maintained covering the applicable procedures
recommended in Regulatory Guide (RG) 1.33, Revision 2, Appendix A, February 1978. Section 1.c of Appendix A recommended procedures for equipment control. Among the procedures the licensee used to implement that requirement were
MA-AA-716-026 were requirements that no material be brought into or stored inside the exclusion zone areas unless prior permission is received from the Shift Manager, that material shall be secured in the exclusion zone to prevent damage in the event of adverse
weather conditions, and that unsecured scaffold parts must be secured in a manner that will prevent them from becoming missile hazards in the event of severe weather. For the supplemental cooling equipment, BwOP MP-26 contained Precaution D.3, which required that all hoses in the transformer area must be properly secured to prevent the hoses from becoming wind-generated hazards that may cause loss of offsite power, and
Step F.7, which directed the operators to secure the hoses that will be used to provide cooling to the main power transformers. Contrary to the above, on three occasions during the inspection period, the inspectors identified unsecured material in the transformer exclusion areas that were placed in the areas without the Shift Manager's approval or were not properly secured. Because the failure to properly implement the
material control procedures was of very low safety significance, and has been entered into the licensee's
NRC Enforcement Policy. (NCV 05000456/2008003-01; 05000457/2008003-01) .3 Readiness for Impending Adverse Weather Conditions a. Inspection Scope On May 30, 2008, the plant experienced a tornado watch as well as high winds and thunderstorms in the area. The inspectors reviewed the preparations and actions of site personnel for protection of risk-significant equipment. The inspectors evaluated the implementation of the licensee's adverse weather procedures, risk assessment, and
compensatory actions. No actual tornado occurred in the area during this time period. Documents reviewed were listed in the Attachment. The inspection constitutes one readiness for impending adverse weather conditions sample as defined in IP 71111.01-05, b. Findings No findings of significance were identified.
Enclosure 1R04 Equipment Alignment (71111.04) .1 Quarterly Partial System Walkdowns a. Inspection Scope The inspectors performed partial system walkdowns of the following risk-significant systems: * 2B diesel generator (DG) while 2A
- AFW [[) train while the 1B train was out of service for troubleshooting and repair of the over speed trip circuit. The inspectors selected these systems based on their risk significance relative to the reactor safety cornerstones at the time they were inspected. The inspectors: * attempted to identify any discrepancies that could impact the function of the system, and, therefore, potentially increase risk; * reviewed applicable operating procedures, system diagrams,]]
- WO [[s), condition reports, and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions; * walked down accessible portions of the systems to verify system components and support equipment were aligned correctly and operable; * examined the material condition of the components and observed operating parameters of equipment to verify that there were no obvious deficiencies; and * verified that the licensee had properly identified and resolved equipment alignment problems that could cause initiating events, or impact the capability of mitigating systems or barriers, and entered them into the]]
- CAP with the appropriate significance characterization. Documents reviewed were listed in the Attachment. These activities constituted three partial system walkdown samples as defined by
IP 71111.04-05. b. Findings No findings of significance were identified.
Enclosure 1R05 Fire Protection (71111.05) .1 Routine Resident Inspector Tours (71111.05Q) a. Inspection Scope The inspectors conducted fire protection walkdowns which were focused on availability, accessibility, and the condition of firefighting equipment in the following risk-significant plant areas: * engineered safety features switchgear room, Division 11 (Zone 5.1-1); * engineered safety features switchgear room, (Zone 5.2-1); * station auxiliary
- DG [[room and diesel oil tank room (Zones 8.7A-0 and 8.7B-0); * auxiliary building elevation 426 (Zone 11.6-0); and * compensatory actions for loss of various Appendix R light packs during Bus 234V outage. The inspectors reviewed areas to assess if the licensee had implemented a fire protection program (]]
FPP) that: * adequately controlled combustibles and ignition sources within the plant; * effectively maintained fire detection and suppression capability; * maintained passive fire protection features in good material condition; and * had implemented adequate compensatory measures for out-of-service, degraded or inoperable fire protection equipment, systems, or features in accordance with the licensee's fire plan. The inspectors selected fire areas based on their overall contribution to internal fire risk as documented in the plant's Individual Plant Examination of External Events with later additional insights, their potential to impact equipment which could initiate or mitigate a
plant transient, or their impact on the plant's ability to respond to a security event. Using the documents listed in the Attachment, the inspectors verified that fire hoses and extinguishers were in their designated locations and available for immediate use; that fire detectors and sprinklers were unobstructed, that transient material loading was within the analyzed limits; and fire doors, dampers, and penetration seals appeared to
be in satisfactory condition. The inspectors also verified that minor issues identified during the inspection were entered into the licensee's
IP71111.05-05. b. Findings No findings of significance were identified.
Enclosure 1R06 Flooding (71111.06) .1 Internal Flooding a. Inspection Scope The inspectors performed a walkdown of the following plant area to assess the adequacy of watertight doors and verify drains and sumps were clear of debris and were operable, and that the licensee complied with its commitments: * Essential service water (SX) pump rooms. The inspectors reviewed: * selected risk important plant design features and licensee procedures intended to protect the plant and its safety related equipment from internal flooding events; * flood analyses and design documents, including the
- UFSAR [[, engineering calculations, and abnormal operating procedures to identify licensee commitments; * licensee drawings to identify areas and equipment that may be affected by internal flooding caused by the failure or misalignment of nearby sources of water, such as the fire suppression or the circulating water systems; and * the licensee's]]
- CAP to verify the adequacy of the corrective actions. The specific documents reviewed were listed in the Attachment to this report. This inspection constituted one internal flooding sample as defined in
CFR Part 50, Appendix B, Criterion V, having very low significance (Green) related to a plant barrier impairment (PBI) procedure. Specifically, the procedure did not contain steps to ensure that compensatory measures in the B Train room of SX were maintained, while required
access covers were removed. Description: The
SX pumps were located in the lowest level of the Auxiliary Building. The system was designed to prevent failure from flooding by separation of components and by designing flood barriers in the doors, walls and ceiling. In order to maintain access to equipment in the room, several removable access covers existed. When installed, those access covers were designed to prevent flooding from system
failures in the areas above the
- SX [[pump rooms from leaking into the room. With the covers removed, sump leak detection and high level alarms were depended upon to warn operators should a leak from above the room occur. When the access covers were removed, several compensatory measures were directed to be put in place in accordance with Procedure Bw]]
AP 1110-3, "Plant Barrier Impairment
Program." The compensatory measures were pre-evaluated for each cover.
Enclosure On April 2, 2008,
- SXFSO 2-3. This hatch had a pre-defined compensatory action to ensure that the room sump alarms were available. On April 7, 2008, while the
- PBI was still in effect, operators determined that the room sump alarms were not functioning. This was documented in the licensee's
PBI in
effect until after the
SX pump room was known to be unavailable for up to fifteen days while an access cover was removed. Analysis: The inspectors determined that the failure to ensure the compensatory measures remained viable was a performance deficiency warranting a significance
evaluation. The inspectors concluded that the finding was finding was greater than minor in accordance with Inspection Manual Chapter (IMC) 0612, "Power Reactor Inspection Reports," Appendix B, "Issue Disposition Screening," because the licensee failed to effectively manage prescribed compensatory measures related to a cornerstone objective. The increase in flooding hazard affected the protection against external factors attribute of the Initiating Events cornerstone. Using the SDP Phase 1 Screening Worksheet of
IMC 0609, Table 4a, the inspectors determined the finding screened as Green because the finding did not increase the likelihood of an external or internal flood. The finding was related to the cross-cutting area of Human Performance. This finding was associated with the cross-cutting aspect of Resources (H.2.(c)) because the barrier impairment procedure was not adequate because it did not ensure safety margins were
maintained by providing instructions to periodically verify that the compensatory measures were still available. Enforcement: Title
- 10 CFR Part 50, Appendix B, Criterion V, required, in part, that activities affecting quality be prescribed by documented procedures of a type appropriate to the circumstances. Contrary to the above, Bw
AP 1110-3 was not adequate because
it did not ensure that the sump flooding alarms remained operational while the flood barrier covers are removed. Once identified, the licensee entered the finding into their
- IR 766773, "PBI Compensatory Actions Changed, Not Identified by Shift." Because the finding was of very low safety significance, and has been entered into the licensee's
- NRC Enforcement Policy. Corrective actions included repairing the sump alarms and planned revision to the
NCV 05000456/2008003-02; 05000457/2008003-02) 1R07 Annual Heat Sink Performance (71111.07) .1 Heat Sink Performance Annual Review a. Inspection Scope The inspectors reviewed the licensee's cleaning and eddy current (ET) testing of the Unit 2 component cooling heat exchanger to verify that potential deficiencies did not
Enclosure mask the licensee's ability to detect degraded performance, to identify any common cause issues that had the potential to increase risk, and to ensure that the licensee was adequately addressing problems that could result in initiating events that would cause an increase in risk. The inspectors reviewed the licensee's observations as compared against acceptance criteria, the correlation of scheduled testing and the frequency of testing, and the impact of instrument inaccuracies on test results. Inspectors also verified that test acceptance criteria considered differences between test conditions, design conditions, and testing conditions. The inspectors also reviewed the licensee's calculation to justify continued operability of the heat exchanger with the additional tubes plugged as a result of these activities. Documents reviewed were listed in the Attachment. This inspection constituted one sample of the annual requirement as defined in
- IP 71111.07-05. b. Findings No findings of significance were identified. 1R08 In-service Inspection (
ISI) Activities (71111.08) For Unit 2, from April 28, 2008, through May 6, 2008, the inspectors conducted a review of the implementation of the licensee's ISI Program for monitoring degradation of the
reactor coolant system (RCS), steam generator (SG) tubes, emergency feedwater systems, risk significant piping and components and containment systems. The inspections described in Sections 1R08.1, 1R08.2, R08.3, 1R08.4 and 1R08.5 below counted as one inspection sample as defined by
- ISI a. Inspection Scope The inspectors observed the following nondestructive examinations (NDE) required by the American Society of Mechanical Engineers (ASME) Code, Section
ASME Code,Section XI and Section V requirements and if any indications and defects were detected, to determine if these were dispositioned in
accordance with the
- NRC approved alternative requirement. * ultrasonic examination (UT) of reactor vessel inlet nozzle-to-safe end weld (2RV-01-024) at the 113 degrees azimuth; *
- XI and Section V requirements and if any indications and defects were detected, to determine if these were dispositioned in accordance with the
NRC approved alternative requirement.
Enclosure * Magnetic particle examination of
SG-03-SGN-02). The licensee did not identify surface or volumetric examinations completed during the previous outage with relevant/recordable conditions/indications accepted for continued
service. Therefore, no
- NRC [[review was completed for this inspection attribute. The inspectors observed fabrication of the following pressure boundary welds (overlay repairs) completed for pressure boundary risk significant systems during the current Unit 2 refueling outage. The inspectors also reviewed weld related documents to determine if the licensee applied the preservice]]
NDE and acceptance criteria required by
the construction Code, and an
- NRC approved Relief Request 12R-48. Additionally, the inspectors reviewed the welding procedure specification and supporting weld procedure qualification records to determine if the weld procedures were qualified in accordance with the requirements of the
- PZR Upper Head Penetration Inspection Activities a. Inspection Scope For the Unit 2 vessel head, no examination was required pursuant to]]
EA-03-009 and the licensee did not complete one during the current
refueling outage. Therefore, no
IP attribute. b. Findings No findings of significance were identified. .3 Boric Acid Corrosion Control a. Inspection Scope The inspectors observed licensee boric acid corrosion control visual examinations for portions of the reactor coolant and/or emergency core cooling systems (ECCS) within

- CAP with the appropriate significance characterization. Documents reviewed were listed in the Attachment. This inspection constituted one quarterly maintenance effectiveness samples as defined in
IP 71111.12-05.
Enclosure b. Findings No findings of significance were identified. 1R13 Maintenance Risk Assessments and Emergent Work Control (71111.13) .1 Maintenance Risk Assessments and Emergent Work Control a. Inspection Scope The inspectors reviewed the licensee's evaluation and management of plant risk for the maintenance and emergent work activities affecting risk-significant and safety-related equipment listed below to verify that the appropriate risk assessments were performed prior to removing equipment for work: * planned work on the Unit 2 component cooling heat exchanger with emergent work on the 1A containment spray train; * change from Mode 4 to Mode 3 with the 2B
- AFW pump unavailable; * emergent troubleshooting on the 2E main power transformer cooling fan power transfer circuit; * emergent work on 2A emergency
DG; and * Bus 242 outage during refueling outage. These activities were selected based on their potential risk significance relative to the reactor safety cornerstones. As applicable for each activity, 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 that the plant risk was promptly reassessed and managed. The inspectors reviewed the scope
of maintenance work, discussed the results of the assessment with the licensee's probabilistic risk analyst or shift technical advisor, and verified plant conditions were consistent with the risk assessment. The inspectors also reviewed TS requirements and walked down portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met. Documents
reviewed were listed in the Attachment. These activities constituted five samples as defined by IP 71111.13-05. b. Findings No findings of significance were identified. 1R15 Operability Evaluations (71111.15) .1 Operability Evaluations a. Inspection Scope The inspectors reviewed the following issues: * control room heating ventilation and air conditioning issues;
Enclosure * Unit 2 containment integrity with equipment hatch removed during fuel movements; * 1A
SX169A to automatically open as expected during a monthly surveillance test; * revision due to extended corrective action dates for AFW tunnel cover modifications; and * 1A containment spray motor oil leak. The inspectors selected these potential operability issues based on the risk-significance of the associated components and systems. The inspectors evaluated the technical
adequacy of the evaluations to ensure that
- TS operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the
- UFS [[]]
AR to the licensee's evaluations, to determine whether the components or systems were operable. Where compensatory measures
were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations. Additionally, the inspectors also reviewed a sampling of corrective action documents to verify that the licensee was identifying and correcting any deficiencies
associated with operability evaluations. Documents reviewed were listed in the Attachment. This inspection constituted five samples as defined in
- AFW Tunnel Hatch Margin to Safety The inspectors reviewed Operability Evaluation 07-007, Revision 2. This operability evaluation was performed because the licensee identified that the design analysis for evaluation of the
AFW tunnel flood seal covers did not include the effects of a high energy line break in the main steam isolation valve tunnels. Following this review, the inspectors questioned why a dynamic load factor as a result of the impulse pressure following a high energy line break had not been considered in an analytic calculation
perform to support the operability evaluation. The licensee documented the inspectors concerns in
- IR 783849. Additionally, following a review of a subsequent revision of this operability evaluation, the inspectors questioned the licensee's conclusion that the operability of the
AFW hatches continued to be supported despite analytical results showing a factor of safety for the
concrete expansion anchors supporting the hatches of less than 2.0, which is contrary to the guidance provided in
- NRC Bulletin 79-02, "Pipe Support Base Plate Designs Using Concrete Expansion Anchors." Additionally, the inspectors noted that the operability evaluation did not address Section C.13 of
NRC Technical Guidance 9900, "Operability Determinations & Functionality Assessment for Resolution of Degraded or
Nonconforming Conditions Adverse to Quality or Safety." Specifically, Section C.13 stated that if a structure was degraded, the licensee should assess the structure's capability of performing its specified function. As long as the identified degradation did not result in exceeding acceptance limits specified in applicable design codes and
Enclosure standards referenced in the design basis documents, the affected structure was either operable or functional. At the close of the inspection period temporary modifications had been
implemented at both units that restored the margin of safety to greater than 2.0. Pending additional follow-up by the inspectors for the timeliness of corrective actions, extent of condition, corrective actions and past operability, this item will remain open. (URI 005000456/2008003-03;05000457/2008003-03) Included in the

Inspection Scope The inspectors reviewed the following temporary modification: * temporary modification on 1B]]
- AFW [[pump (substitution of automatic over speed trip function with manual operator actions to trip diesel on over speed); and * main steam isolation valve tunnel blowout panel/AFW hatch temporary modification. The inspectors compared the temporary configuration change and associated]]
UFSAR, and the TS, as applicable, to verify that the modification did not affect the operability or availability of the affected system. The inspectors, as applicable, performed field verifications to ensure that the modification was installed as directed; the
modification operated as expected; modification testing adequately demonstrated continued system operability, availability, and reliability; and that operation of the modification did not impact the operability of any interfacing systems. Lastly, the inspectors discussed the temporary modification with operations, engineering, and training personnel to ensure that the individuals were aware of how extended operation with the temporary modification in place could impact overall plant performance. This inspection constituted two samples as defined in IP71111.18-05. b. Findings No findings of significance were identified. 1R19 Post Maintenance Testing (71111.19) .1 Post Maintenance Testing a. Inspection Scope The inspectors reviewed the following post-maintenance activities to verify that procedures and test activities were adequate to ensure system operability and functional capability:
Enclosure * 2B
- SX pump following motor replacement; * 2C heater drain pump after replacement and rework on shaft packing; * 2B feedwater pump after work on the stop valve; and * 1B
- AFW [[pump following troubleshooting of failure of the over speed trip. These activities were selected based upon the structure, system, or component's ability to impact risk. The inspectors evaluated these activities for the following (as applicable): * the effect of testing on the plant had been adequately addressed; * testing was adequate for the maintenance performed; * acceptance criteria were clear and demonstrated operational readiness; * test instrumentation was appropriate; * tests were performed as written in accordance with properly reviewed and approved procedures; * equipment was returned to its operational status following testing (temporary modifications or jumpers required for test performance were properly removed after test completion), and test documentation was properly evaluated. The inspectors evaluated the activities against]]
- NRC [[generic communications to ensure that the test results adequately ensured that the equipment met the licensing basis and design requirements. In addition, the inspectors reviewed corrective action documents associated with post-maintenance tests to determine whether the licensee was identifying problems and entering them in the]]
CAP and that the problems were being
corrected commensurate with their importance to safety. Documents reviewed were listed in the Attachment to this report. This inspection constituted five samples as defined in IP 71111.19-05. b.

Enclosure Description: On May 1, 2008, the inspectors identified that the licensee had failed to sample the temporary wastewater storage tanks that were installed for the Unit 2 refueling outage to hold shower and wash water from the Unit 2 Containment Access Facility at the required frequency of seven days. This failure resulted in two missed samples of the Unit 2 Containment Access Facility shower tanks. The licensee's corrective measures consisted of immediately collecting and monitoring the required
sample. The results of this sample indicated that the quantity of radioactive material was well below the limits provided in the
RP-BR-654, Revision 0. This revision was necessary to reflect the temporary tank sampling requirement of TRM, Appendix L, implemented to limit the quantity of radioactive material contained in outside temporary tanks and verify
the compliance with the limits by sampling the contents at least once per seven days when in use. The inspectors observed that Procedure
- IR 770446, conducted the required sampling, revised the scheduling tool to ensure the tank is sampled at least every seven days, and planned to revise Procedure
BR-654. Analysis: The inspectors determined that the failure to sample the contents in the outdoor liquid radwaste storage tanks did not meet the requirements of TRM, Appendix L and was a performance deficiency that warranted a significance evaluation. The finding involves an occurrence in the licensee's radioactive material control program that is contrary to the licensee's procedures. The finding was more than minor because it impacted the program and process attribute of the Public Radiation Safety Cornerstone and affected the cornerstone objective to ensure adequate protection of
public health and safety from exposure to radioactive material released into the public domain, in that the failure to measure the levels of radioactivity in the temporary storage tanks had the potential to impact the licensee's effluent program. The inspectors applied the IMC 0609, Appendix D, to this finding. The finding is in the licensee's radiological effluent monitoring program. The finding did not involve a failure
to implement the effluent release program nor did public dose exceed Appendix I, Criterion, or
- 10 CFR [[20.1302(e) and the finding was determined to be of very low safety significance (Green). This conclusion was based on no tank contents being released or discharged without sampling, and the total content limits were not exceeded. The primary cause of this sampling failure was related to the cross-cutting component of Human Performance, Work Practices (Item H.4.C of]]
IMC 0305) because the licensee did not ensure that supervisory and management oversight of procedure development was adequate to assure nuclear safety, specifically, procedures that are complete, accurate. Enforcement: Technical Specification 5.4.1(a) requires written procedures be established, implemented and maintained covering the applicable procedures
recommended in
- TRM [[, Appendix L, required the quantity of radioactive material contained in any outside temporary tank be determined to be within the acceptance criteria by analyzing a representative sample of the tank's contents at least once per seven days when radioactive materials are being added to the tank. Procedure]]
BR-654 was written to implement the requirements of the
- BR [[-654 did not include the requirement for sampling at least once per seven days. Consequently, the licensee failed to sample decontamination drain waste tanks, temporary tanks, adjacent to the Unit 2 Containment Access Facility at least once per seven days. Because of the very low safety significance of this finding and because the issue was entered into the licensee's]]
IR 770446), it was treated as an NCV, consistent with
Section

PI definition and guidance contained in the Nuclear Energy Institute
(NEI) Document 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 5, was used. The inspectors reviewed the licensee's
LERs, and NRC Integrated Inspection reports for the period of April 1, 2007, to March 31, 2008 to validate the accuracy of the submittals. The inspectors also reviewed the licensee's issue report database to determine if any
problems had been identified with the

an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. Attributes reviewed included: * the complete and accurate identification of the problem; * that timeliness was commensurate with the safety significance; * that evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrences reviews were proper and adequate; and * that the classification, prioritization, focus, and timeliness of corrective actions were commensurate with safety and sufficient to prevent recurrence of the issue. Minor issues entered into the licensee's
- CAP [[as a result of the inspectors' observations are included in the attached list of documents reviewed. These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples. Instead, by procedure they were considered an integral part of the inspections performed during the quarter and documented in the Attachment. b. Findings No findings of significance were identified. .2 Daily]]
CAP Reviews a. Scope In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensee's CAP. This review was accomplished through inspection of the station's daily condition report packages.
Enclosure These daily reviews were performed by procedure as part of the inspectors' daily plant status monitoring activities and, as such, did not constitute any separate inspection samples. b. Findings No findings of significance were identified. .3 Semi-Annual Trend Review a. Scope The inspectors performed a review of the licensee's
- CAP and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors' review was focused on repetitive equipment issues, but also considered the results of daily inspector
CAP item screening discussed in Section 4OA2.2 above,
licensee trending efforts, and licensee human performance results. The inspectors' review nominally considered the six month period of September 1, 2007 through March 31, 2008, although some examples expanded beyond those dates where the scope of the trend warranted. The review also included issues documented outside the normal
- CAP [[in major equipment problem lists, repetitive and/or rework maintenance lists, departmental problem/challenges lists, system health reports, quality assurance audit/surveillance reports, self assessment reports, and Maintenance Rule assessments. The inspectors compared and contrasted their results with the results contained in the licensee's]]
CAP trending reports. Corrective actions associated with a sample of the issues identified in the licensee's trending reports were reviewed for adequacy. Documents reviewed were listed in the Attachment.
This review constituted a single semi-annual trend inspection sample as defined in Inspection Procedure 71152-05. b. Findings No findings of significance were identified. 4OA3 Follow-up of Events and Notices of Enforcement Discretion (71153) .1 Seismic Event a. Inspection Scope The inspectors reviewed the plant's response to a seismic event felt at the plant due to an earthquake in southern Illinois on April 18, 2008. Although the ground motion was felt in the plant, the motion was apparently not strong enough to activate the seismic
monitoring system and annunciators. The inspectors collected the information necessary to communicate the event details to regional supervision, observed plant parameters and licensee activities, confirmed that the licensee had properly classified the event, and conducted independent walkdowns of risk significant plant areas to verify
Enclosure that no damage had occurred. The walkdowns included an inspection of all blowdown line vacuum breaker vaults, the areas over the buried blowdown piping, and the tritium mitigation pumping systems. Documents reviewed in this inspection were listed in the Attachment. This inspection constituted one sample as defined in
- TI [[) 2515/166, "Pressurized Water Reactor Containment Sump Blockage (NRC Generic Letter [GL] 2004-02)" - Units 1 and 2 a. Inspection Scope The inspectors reviewed the station implementation of the licensee's commitments documented in their December 31, 2007, response to]]
- GL 2004-02, "Potential Impact of Debris Blockage on Emergency Recirculation during Design Basis Accidents at Pressurized Water Reactors." The inspectors reviewed the Engineering Change Packages associated with the sump strainer modifications and the 10
CFR 50.59 evaluations for these Engineering Change Packages (ECs). The inspectors also reviewed documentation from the licensee and vendor pertaining to the strainer
assembly specifications. In addition, the inspectors reviewed three samples of the completed and approved for use changes for the
- UFSAR , Revision 12, that have not been incorporated yet and one sample already incorporated in Revision 11. The documents reviewed were listed at the end of the report. The inspection was conducted in accordance with
- TI 2515/166. Inspection Documentation The inspectors determined the following answers to the Reporting Requirements detailed in the
- TI 2515/166: (1) Did the licensee implement the plant modifications and procedure changes committed to in their

- RCS Dissimilar Metal Butt Welds (DMBW) (TI 2515/172, Revision 0) a. Inspection Scope The inspectors conducted a review of the licensee's
- DMBW mitigation and inspection program to determine if it was implemented in accordance with the industry self-imposed mandatory requirements of Materials Reliability Program (
MRP) -139, "Primary System
Piping Butt Weld Inspection and Evaluation Guidelines." This review was conducted in accordance with
- TI [[2515/172, "Reactor Coolant System Dissimilar Metal Butt Welds" for both Units 1 and 2. The documents reviewed by the inspector for this inspection were listed in the Attachment. From April 28, 2008, through May 6, 2008, the inspectors performed a review in accordance with]]
- DMBW s included applicable welds exposed to pressurizer, hot let and cold leg temperatures; * if the schedules for these baseline inspections were consistent with the requirements stated in
MRP-139 baseline inspection schedules; and
Enclosure * the inspectors verified that the licenses had completed weld overlays on all Unit 2 pressurizer
- DMBW s during the Spring 2008 refueling outage. (2) Volumetric Examinations The inspectors observed and/or reviewed records for the following volumetric examinations for: * Unit 1, the inspectors performed a review of
- UT records from the Fall 2007 for the unmitigated reactor vessel outlet nozzle-to-safe end Inconel weld (1RV 01-22) at the 22 degree azimuth location; and * Unit 2, the inspectors observed the licensee's vendor acquiring and analyzing
- RV -01-24) at the 113 degree azimuth location. The inspectors reviewed records of the following weld overlay volumetric examinations for: * Unit 1, the inspectors performed a review of
- DMBW (1PN 01-SW-1) and the adjacent stainless steel safe-end to pipe/fitting welds; and * Unit 2, the inspectors performed a records review from the current outage of the
- SW -6) and the adjacent stainless steel safe-end to pipe/fitting welds. The inspectors performed the reviews of volumetric examinations identified above to determine if: * the examinations were performed in accordance with the guidelines in
NRC staff relief request authorization for the weld overlay; * the examination coverage warranted further evaluation and if so, the inspector reviewed the licensee's basis for achieving the inspection coverage credited; * the volumetric examinations were performed by qualified personnel; and * deficiencies were appropriately dispositioned. (3) Weld Overlays For Unit 1, the inspectors performed a review of licensee records for the pressurizer surge nozzle (1-PN-01-SW-1) weld overlay completed in the Fall 2007.
Enclosure For Unit 2, the inspectors observed the weld overlay repairs completed for the pressurizer safety nozzle "A" (2PZR-01-SE-02) and safety nozzle "B" (2PZR-01-SE-04). The inspectors performed the review of weld overlays identified above to determine if: * the overlays were performed in accordance with
- NRC staff relief request authorizations; * the licensee submitted appropriate relief requests and obtained
- NRR staff authorization to install the weld overlays; * the overlay welding was performed by qualified personnel; and * deficiencies were appropriately dispositioned, and resolved. (4) Mechanical Stress Improvement (
- SI ) There were no stress improvement activities performed or planned by the licensee. Therefore, the inspectors did not perform a review for this inspection attribute. (5)
- DMBW [[s were categorized as "H" or "I" and for these welds, the licensee's basis for this categorization and the licensee's plans to address the potential for primary water stress corrosion cracking; and * deviations were planned from the inspection guidelines of]]
- MRP -139. b. Observations Summary: Braidwood Units 1 and 2 are Westinghouse four loop design plants. For each unit, the licensee had identified a population of
- DM [[]]
BWs susceptible to primary
water stress corrosion cracking in accordance with
- MRP -139 guidelines. The licensee had completed mitigation by weld overlay repairs to the pressurizer
MRP-139 categories "D" and "E").
Enclosure For Unit 1, during the Fall 2007 outage, the licensee completed baseline examinations of the pressurizer
- DMBW on the pressurizer surge line, since it was not inspected or mitigated by December 31, 2007. The licensee completed weld overlay repairs on the pressurizer
- DMBW at the pressurizer surge line. The inspectors confirmed that the licensee performed appropriate weld overlay repairs and
- TI 2515/172, Revision 0, the inspectors evaluated and answered the following questions: (1) Licensee's Implementation of the
- MRP -139 Baseline Inspections 1. Have the baseline inspection been performed or are they scheduled to be performed in accordance with
- DMBW s of the nine plants listed in 03.01.b completed during the spring outages? Yes. Baseline inspections of the Braidwood Unit 2 pressurizer
- DMBW s were completed after applying weld overlay repairs during the Spring 2008 outage. 2. Is the licensee planning to take any deviations from the
- MRP -139 baseline inspection requirements? If so, what deviations are planned, what is the general basis for the deviation, and was the
NEI- 03-08 process for filing a deviation followed? No. The licensee was not planning to take any further deviations from the MRP-139 baseline inspection requirements. For Unit 2, the
licensee had previously taken a deviation from MRP-139 for the
pressurizer
- DMBW 's, since they were not inspected or mitigated by December 31, 2007. The basis for this deviation was the low susceptibility of the material and the timing of the Spring 2008 refueling outage. The
- NEI -03-08 process for filing the deviation was followed. The licensee completed weld overlay repairs on the pressurizer
- DM [[]]
BWs during the current outage. The inspectors confirmed that the licensee performed appropriate weld overlay
repairs and
DMBW's such that a deviation from the MRP-139 guidelines no longer existed.
Enclosure (2) Volumetric Examinations 1. Performed in accordance with the examination guidelines in
- MRP -139, Section 5.1, for unmitigated welds or mechanical stress improvement welds and consistent with
- NRC staff relief request authorization for weld overlaid welds? Yes. For Unit 1, the inspectors performed a records review of the
- UT data for the unmitigated reactor vessel outlet nozzle-to-safe end Inconel weld at the 22 degree azimuth location. The licensee's vendor use a Performance Demonstrated Initiative (
- XI required weld volume. Yes. For Unit 2, the inspectors observed the licensee's vendor acquiring and analyzing
- UT data for the unmitigated reactor vessel inlet nozzle-to-safe end Inconel weld at the 113 degree azimuth location. The licensee's vendor used a
- XI required weld volume. 2. Performed by qualified personnel? (Briefly describe the personnel training/qualification process used by the licensee for this activity.) Yes. For both Units, the licensee's vendor staff that analyzed the
UT Level II requirements in accordance
with a vendor procedure (WDP-9.2 WesDyne International Qualification and Certification of Personnel in Nondestructive Examination) to meet the training and certification requirements of the
VIII. For Unit 2, the inspectors also confirmed that the two dayshift vendor UT analysts
had certification records issued by the
- VIII [[supplement for examination of these welds. 3. Performed such that deficiencies were identified, dispositioned, and resolved? Not applicable. No deficiencies or recordable indications were identified in the unmitigated nozzle-to-safe end Inconel welds. (3) Weld Overlays 1. Performed in accordance with]]
NRR staff authorization to install the weld overlays?
Enclosure Yes. For each Unit, the weld overlays were performed in accordance with
- NRR [[staff authorization to install the weld overlays. 2. Performed by qualified personnel? (Briefly describe the personnel training/qualification process used by the licensee for this activity.) Yes. For the weld overlays reviewed by the inspectors in each Unit, the welders fabricating the overlay had performed an]]
ASME Code,Section IX - Welder Performance Qualification in accordance with the vendor's program for the weld overlay activities performed.
The welder qualification records were transmitted to Exelon for review and concurrence in support of the A2R13 weld overlay work. The inspectors reviewed the welder qualification records including the welders'
- ASME Code - Welder Maintenance Log. 3. Performed such that deficiencies were identified, dispositioned, and resolved? Yes. For Unit 1, rejectable surface indications were identified during the final weld overlay dye penetrant examination (
- PT ). The licensee removed a small amount of weld material to remove these indications (e.g., buffed out) and reperformed a final
PT records for the weld overlays affected and considered these
deficiencies appropriately dispositioned and resolved. Yes. For Unit 2, the licensee's vendor encountered problems resulting in loss of shielding gas during weld overlay fabrication. The licensee's vendor ground out affected weld metal and rewelded portions of the overlay repair. Similar to the Unit 1 overlay, the
licensee identified rejectable indications during the final weld overlay
- PT examinations for Unit 2. The licensee removed a small amount of weld material to remove these indications (e.g., buffed out) and reperformed a final
PT to accept the weld overlay repairs. The inspectors reviewed the final PT records for the weld overlays
affected and considered these deficiencies appropriately dispositioned and resolved. For Unit 2, during fabrication of the "B" safety nozzle, the licensee vendor identified that the overlap for the sacrificial layer weld was not in accordance with the weld procedure. The licensee removed
(e.g., ground off) the incorrect weld overlap, completed a PT of the ground area, and then completed a proper weld overlap. The inspectors concluded that the licensee had taken appropriate corrective actions to resolve this deficiency.
Enclosure (4) Mechanical Stress Improvement No stress improvement activities have been performed for
- DMBW s nor did the licensee plan to perform mechanical stress improvement as a mitigation strategy for
- ISI program? If not, briefly summarize the licensee's basis for not having a documented program and when the licensee plans to complete preparation of the program. No. The licensee had not prepared a separate
MRP-139 guidelines
and the
- MRP -139? If any welds are not appropriately categorized, briefly explain the discrepancies. Yes. For each Unit, the
- MRP -139. 4. If any welds are categorized as H or I, briefly explain the licensee's basis of the categorization and the licensee's plans for addressing potential
- PWSCC. For Unit 2, the pressurizer welds were categorized as "H" prior to the application of a structural weld overlay. The Category H was assigned due the difficulty of performing a
- PDI [[]]
UT examination of these welds.
After completing the weld overlay repairs, the licensee indicated that these
NEI 03-08 process for filing deviations followed? Not applicable. The licensee was not planning to take deviations from the MRP-139 guidelines.

- URI concerning the lack of procedural controls for labeling Regulatory Guide (RG) 1.97 post-accident indications on the main control room control panels. The inspectors opened
NRC and other information documenting commitments, current status, and corrective actions to be taken for post-accident instrument labeling deficiencies. The inspectors reviewed the corrective action document (IR 688723), the licensee's plans to revise Procedures 1BwOSR 3.3.3.1, "Unit One Accident Monitoring Instrumentation Channel Checks" and 2BwOSR 3.3.3.1, "Unit Two Accident Monitoring Instrumentation Channel Checks," and Training Requests submitted to ensure familiarity
with equipment included in Braidwood
- TS , Table 3.3.3-1, "Post Accident Monitoring Instrumentation." b. Findings Introduction: The inspectors identified a finding of very low safety significance (Green) and associated
NCV of TS 5.4.1, for failure to maintain adequate procedural controls for
labeling
RG 1.97 instruments dated September 1, 1987. This letter committed the licensee to identifying post-accident instruments per RG 1.97, Revision 3, as part of their Detailed Control Room Design Review. Currently, no Braidwood Station procedure describes or
controls these markings, which consist of a black dot on the panel next to the indicator. The markings were intended to indicate qualification for reliability under accident conditions. Therefore, if multiple indications conflicted during an accident, the operators should prefer the indicators with a black dot. The inspectors identified that markings existed for numerous post-accident indications on both units' control panels and the simulator. When questioned about how these markings were controlled, the licensee stated that they were informally controlled as part of the
- PASSPO [[]]
- RT database panels and was initially unable to provide a list of marked instruments due to the large number of
- PASSPO RT database. To address the concern regarding the accuracy of these markings, the licensee walked down the panels, and reviewed the source documents and
- PASSPO [[]]
RT further. It was
Enclosure determined that there were errors in both the Unit 1 and Unit 2 control rooms and the simulator, which included the following discrepancies: * Control Room Indicator
- IR [[688723, corrected the discrepancies identified by labeling the appropriate post-accident instruments and initiated Training Requests to evaluate the need for familiarization on post-accident monitoring instrumentation. In addition, the licensee planned to revise Procedures 1Bw]]
OSR 3.3.3.1, "Unit One Accident Monitoring
Instrumentation Channel Checks" and 2BwOSR 3.3.3.1, "Unit Two Accident Monitoring Instrumentation Channel Checks" to validate RG 1.97 labeling periodically. The procedure revisions were being tracked by action tracking item 709180-02. Analysis: The inspectors determined that the licensee's failure to perform adequate procedural controls was a performance deficiency warranting a significance evaluation in
accordance with
- IMC [[0612, Appendix B. The inspectors concluded that the finding was greater than minor because it could become a more significant safety issue if left uncorrected. Inaccurately labeled control room indicators of post-accident instrumentation could lead to confusion and hamper operator response if conflicting indications resulted due to accident conditions. Using]]
- IMC [[0609.04, the inspectors concluded that this issue was of very low safety significance (Green) because the finding was did not represent; a design or structure, system and component qualification deficiency; a loss of system safety function; an actual loss of safety function or exceed]]
TS, risk-significant trains; or a potentially risk-significant
scenario related to external initiating events. The inspectors did not identify a cross-cutting aspect to this finding.
Enclosure Enforcement: Technical Specification 5.4.1 required, in part, that written procedures be established and implemented for activities provided in
- UFSAR 13.5, "Plant Procedures," stated that a formalized system of written procedures containing administrative and operating instructions in conformance with
RG 1.33 was employed to ensure that all abnormal or emergency activities were
conducted in a safe manner. Contrary to the above, the inspectors identified that the licensee failed to control labeling of control panels for uniquely identifying RG 1.97 equipment. Specifically, the licensee failed to control labeling on both units' control panels and the simulator, resulting in improperly marked post-accident indicators. However, because this violation was of
very low safety significance and was entered into the licensee's
NRC Enforcement Policy.

Inspection Scope During the inspection period, the inspectors conducted observations of security force personnel and activities to ensure that the activities were consistent with licensee security procedures and regulatory requirements relating to nuclear plant security. These observations took place during both normal and off-normal plant working hours. These quarterly resident inspector observations of security force personnel and activities did not constitute any additional inspection samples. Rather, they were considered an
integral part of the inspectors' normal plant status review and inspection activities. b. Findings No findings of significance were identified.
