SUBJECT: CALLAWAY PLANT - NRC PROBLEM IDENTIFICATION AND RESOLUTION

INSPECTION REPORT 05000483/2008006

Dear Mr. Naslund:

On March 14, 2008, the U. S. Nuclear Regulatory Commission completed a team inspection at

your Callaway Plant. The enclosed report documents the inspection findings, which the team

discussed on March 14, 2008, with Mr. A. Heflin, Vice President - Nuclear, and other members of

your staff during the exit meeting.

The team examined activities conducted under your lic

ense as they relate to the identification and

resolution of problems, compliance with the Commission's rules and regulations, and the

conditions of your operating license. Within these areas, the inspection involved examination of

selected procedures and representative records, observations of activities, and interviews with

personnel. The team reviewed 246 Callaway Action Requests, associated root and apparent

cause evaluations, and other supporting documents. The team reviewed an additional

124 Callaway Action Requests related to specific areas - essential service water, component

cooling water, 480 Vac auxiliary contacts, and sa

fety conscious work environment. The team

reviewed cross-cutting aspects of NRC findings and interviewed personnel regarding the condition

of your safety conscious work environment at the Callaway Plant.

Based on the sample selected for review, the team concluded that your staff continued to have

challenges in the area of prioritization and evaluation, which need additional attention. The team

also noted that performance related to problem identification and resolution had improved. The

team determined that you're your staff had used the self-assessment process and quality

assurance organization to improve site perfo

rmance. The team determined the improvement

resulted from corrective action process

improvements implemented in January 2007, and

management oversight process changes implem

ented following receipt of substantive

cross-cutting issue in problem identification and resolution.

Because of the increased number of allegations at your facility in Calendar Year 2007, especially

the discrimination concerns, the team interviewed

a large number of personnel related to the safety

conscious work environment at the Callaway Plant. In addition, because of the nature of the

concerns expressed in the allegations, the team asked additional questions to gain insights into the

safety conscious work environment at your fa

cility. The team documented the nature of the

concerns and the scope of the evaluations in Attachment 3. The team determined that not all

individuals were comfortable using all of the methods available to them for reporting concerns;

however, all personnel interviewed stated that they would have used at least one of the methods

AmerenUE

- 2 -available for reporting a safety concern. The team determined that our review results remained

consistent with other safety culture surveys that

you had completed within the last year. The team

determined that some general culture and work environment issues continued to be present that

were outside NRC regulatory jurisdiction, which if not addressed could potentially affect the safety

conscious work environment at the Callaway Plant.

The team identified one finding for failure to determine whether you had a non-conservative

technical specification surveillance requirement.

The team attributed this to improper processing of

operating experience. This finding violated NRC requirements. However, because of the finding

had very low safety significance and because the finding had been entered into your corrective

action program, the NRC is treating this findings as a noncited violation, in accordance with

Section VI.A.1 of the NRC's Enforcement Policy. In addition, one licensee-identified violation of

very low safety significance is listed in this repor

t. If you contest the violations or the significance

of the violations, you should provide a response within 30 days of the date of this inspection report.

Include the basis for your denial, to the U. S. Nuclear Regulatory Commission, ATTN: Document

SUMMARY OF ISSUES

IR 05000483/2008006; 2/11/2008 - 3/14/2008; Callaway Plant; Biennial inspection of the

identification and resolution of problems

One senior reactor inspector, one senior project engineer, three reactor inspectors, and a resident

inspector conducted the inspection. The team identified one noncited violation during this inspection.

The significance of most findings is indicated by their color (Green, White, Yellow, Red) using

Inspection Manual Chapter 0609, "Significance Determination Process." Findings for which the

Significance Determination Process does not apply may be Green or be assigned a severity level

after NRC management review. The NRC's program for overseeing the safe operation of

commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process,"

Revision 4, dated December 2006.

Identification and Resolution of Problems

The team reviewed 246 Callaway Action Requests, several job orders, engineering evaluations,

associated root and apparent cause evaluations, and other supporting documentation to assess

problem identification and resolution activities. The team reviewed an additional 124 Callaway Action

Requests related to specific areas - essential service water, component cooling water, 480 Vac

auxiliary contacts and safety conscious work envir

onment. Based on the sample selected for review, the team concluded the licensee continued to have challenges in the area of prioritization and

evaluation, which require additional effort. The team also noted that licensee performance related to

problem identification and resolution had improved. The team determined the licensee had used the

self-assessment process and quality assurance organiza

tion to improve site performance. The team

determined the improvement resulted from correct

ive action process impr

ovements implemented in

January 2007, and management oversight changes impl

emented following receipt of substantive

cross-cutting issue in problem identification and resolution.

The team determined that the licensee had initiated actions that improved the quality of their

operability assessments, operational decision-making, and knowledge of the detailed design and

licensing basis since the last evaluation. The graduated approach to assigning cause evaluations for

conditions adverse to quality and the change that required the Callaway Action Request screening

committee to review all Callaway Action Requests provided increased assurance in the ability of the

licensee to identify and effectively resolve conditions adverse to quality.

The team determined that the licensee properly evaluated industry operating experience when

performing root cause and higher tier cause evaluations; however, the licensee had continued

challenges effectively evaluating industry operating experience.

The team determined that licensee audits and assessments continued to be detailed, probing, and

self-critical. The licensee continued to use benchmarking of industry best practices and third party

evaluations that improved the corrective action pr

ogram performance during this assessment period.

The licensee had effectively implemented performanc

e improvements to address the substantive

cross-cutting issue (refer to March 2, 2007, End of Cycle letter) related to evaluating actions required

for conditions adverse to quality as demonstrated by the decreased number of findings in the latter

half of this assessment period and lower affect that poor evaluations had on the facility. However, the licensee will need to apply additional effort to a

ffect improvements.

The improving performance

resulted from increased management involvement in

the corrective action program and in daily

activities.

- 3 - Enclosure

Because of the increased number of allegations at the facility in Calendar Year 2007, including

several discrimination concerns, the team interviewed more personnel than normal to assess the

safety conscious work environment at the Callaway Plant. The team documented the nature of the

concerns and the increased scope of the evaluations in Attachment 3. The team determined that not

all individuals were comfortable using all of the methods available to them for reporting concerns;

however, all personnel would have used at least one of

the methods available for reporting a safety

concern. In addition, the team determined that the employee concerns program requires more

visibility and that not all personnel had confidence in the employee concerns program. The team

determined that our review results remained consistent with other safety culture surveys that

Callaway Plant had completed within the last year. The team determined that some general culture

and work environment issues continued to be present from the last assessment that were outside

NRC regulatory jurisdiction, which if not addressed could potentially affect the safety conscious work

environment at the Callaway Plant.

A. Inspector-Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

Specification Surveillance Requirements for the NK11 and NK14 safety-related batteries

established limits that met the design requirements. Specifically, until questioned by the team

the licensee failed to determine the required design value needed to assure plant safety as

requested in Callaway Action Request 200706561. The licensee determined

that 69 micro-ohms should be the actual allowed inter-cell voltage limit to meet the design

requirements versus an allowed Technical Specification limit of 150 micro-ohms.

The performance deficiency associated with this finding involved the failure to ensure that the

NK11 and NK14 safety-related batteries would remain operable if all the inter-cell connections

measured 150 micro-ohms as allowed by

Technical Specification Surveillance

Requirements 3.8.4.2 and 3.8.4.5. This finding was greater than minor because it was

associated with the Mitigating Systems cornerstone attribute of maintenance and testing and

affects the associated cornerstone objective to ensure the availability, reliability, and

capability of systems that respond to initiating events to prevent undesirable consequences.

Using Manual Chapter 0609.04, "Phase 1 - Initial Screening and Characterization of

Findings," the finding was determined to have very low safety significance because it was a

design deficiency confirmed not to result in loss of operability. The finding had a cross-cutting

aspect in the area of problem identification and resolution associated with operating

experience because the licensee failed to evaluate

in a timely manner relevant internal and

external operating experience P.2(a) (Section 4OA2.e).

B. Licensee-Identified Violations

Violations of very low safety significance, which were identified by the licensee have been

reviewed by the inspectors. Corrective actions taken or planned by the licensee have been

entered into the licensee's corrective action program. These violations and corrective actions

are listed in Section 4OA7 of this report.

REPORT DETAILS

4 OTHER ACTIVITIES (OA)

4OA2 Identification and Resolution of Problems

The team based the following conclusions, in part, on all issues that the team reviewed during

the assessment period, which ranged from November 1, 2006, to March 14, 2008. The team

divided the issues into two groups. The first group (current issues) included problems

identified during the assessment period where at least one performance deficiency occurred

during the assessment period. The second group (historical issues) included issues identified

during the assessment period but had performance deficiencies that occurred outside the

assessment period.

a. Assessment of the Corrective Action Program Effectiveness

(1) Inspection Scope

The team reviewed items from across the seven

cornerstones to verify that the licensee:

(1) identified problems at the proper threshold and entered them into the corrective action

system, (2) adequately prioritized and evaluated issues, and (3) established effective and

timely corrective actions to prevent recurrence.

The team performed field walk downs of the

component cooling water system and the 480 Vac breakers to inspect for deficiencies that

personnel should have entered into the corrective action program. The team reviewed

operator logs and station job orders to ensure personnel entered conditions adverse to quality

into the corrective action program. Additionally, the team reviewed a sample of

self-assessments, trending reports, system health reports, and various other documents

related to the corrective action program.

The team interviewed station personnel, attended screening committee, leadership and

Corrective Action Review Board meetings, and

evaluated corrective action documentation to

determine the threshold for entering problems into their corrective action program. The

meetings assisted the team with their assessment of the threshold of prioritization and

evaluation of identified issues. The team performed a historical review of Callaway Action

Requests written over the last 5 years that addressed the component cooling water system

and the 480 Vac breakers.

The team reviewed plant records, primarily Callaway Action Requests and job orders, to verify

that the licensee developed and implemented corrective actions for identified problems,

including corrective actions to address common cause or generic concerns. The team

sampled specific technical issues to evaluate the adequacy of operability determinations.

Additionally, the team reviewed Callaway Action Requests that addressed past

NRC-identified and self-identified violations to ensure that the corrective actions addressed

the issues as described in the inspection reports. The team reviewed a sample of corrective

actions closed to other Callaway Action Requests, job orders, or other processes

to ensure that the licensee had appropriately im

plemented the corrective actions in a timely

manner.

- 5 - Enclosure

(2) Assessments

(a) Assessment - Effectiveness of Problem Identification

The licensee identified deficiencies as conditions adverse to quality and entered them into the

corrective action program. From the inspecti

on sample, the team identified only one example

for failure to identify excessive nuisance alarms as a condition adverse to quality.

Consequently, the licensee did not resolve the nuisance alarms in a timely manner.

Otherwise, the team determined that the licensee had established an appropriate threshold

for identifying adverse conditions. The team determined that the licensee had lowered their

identification threshold, which improved their ability to identify conditions adverse to quality

during this assessment period. In addition, the team verified that the screening committee

evaluated all Callaway Action Requests to ensure that they identified any related adverse

condition no matter the Callaway Action Request type (i.e., adverse condition, business

tracking, training request, or request for resolution).

In response to the previous inspection, the team verified that the licensee had eliminated

Action Notices, which had resulted in violations during the previous inspection for various

reasons. The team verified that the licensee had appropriately evaluated open Action Notice

Callaway Action Requests to verify whether any adverse conditions required a cause

evaluation and more timely corrective actions. The team evaluated and found no instances of

a Significance Level 6 Callaway Action Request tracking an adverse condition. The licensee

had replaced the Action Notices with the business tracking Significance Level 6 Callaway

Action Requests.

The team determined that licensee quarterly trend reports appropriately discussed and

tracked resolution of identified trends. The licensee recently initiated actions to lower the

threshold for identifying adverse trends so they could better utilize this tool to improve their

performance. The team verified that the licensee identified and recognized their adverse

trends, which represented improved performance

since the last corrective action program

inspection.

Current Issues

Example: From interviews with security officers, the team determined that audible alarms on

a security feature sounded too often and decreased the sensitivity of the officers to monitor

the alarms as expected. The team determined that, although the security personnel and the

system engineer knew about the issue, no one had initiated a Callaway Action Request

documenting the excessive number of nuisance

alarms. Officers had verbally reported and

sent e-mails to the system engineer who had contacted the vendor and made adjustments,

which had reduced the alarms; however, the alarms continued. The team determined that

this deficiency was minor since the security feature remained capable of performing its

intended function. The licensee documented this deficiency in Callaway Action

Request 200801877.

- 6 - Enclosure

Historical Issues

Example 1: Licensee personnel failed to initiate Callaway Action Requests for conditions adverse to quality, as required by 10 CFR Part 50, Appendix B, Criterion XVI. Documenting

these degraded conditions may have prevented a main steam line water hammer event in

June 2006 and may have identified, in August 2005, an additional high point air trap in the

Train A safety injection discharge piping that could impact system operability (NRC Inspection

Report 05000483/2006012-01).

Example 2: The team considered two Action Notice Callaway Action Requests (200602989

and 200608806), identified during this inspection, as inappropriately classified conditions

adverse to quality contrary to 10 CFR Part 50, Appendix B, Criterion V, and their corrective

action program (NRC Inspection Report 05000483/2006012-02).

Example 3: The licensee failed to identify three Action Notice Callaway Action Requests as

conditions adverse to quality (200603636, 200604166 and 200605466); however, the team

determined these examples represented minor findings.

Example 4: During audits from January 2005 through October 9, 2006, the licensee identified

63 Callaway Action Requests that personnel had initiated as action notices rather than

conditions adverse to quality. Quality Assurance issued Callaway Action Request 200606131

to document that personnel incorrectly listed six deficiencies as Action Notice Callaway Action

Requests instead of conditions adverse to quality. During review of the third quarter audit

data, the team identified an additional eight Action Notice Callaway Action Requests that the

audit process should have identified. This represented a 33 percent increase. The team

confirmed that the licensee had appropriately determined that personnel had misclassified

0.5 percent of the Action Notice Callaway Action Requests; however, the team verified none

of the misclassified items documented significant deficiencies.

Example 5: Plant operations and security had several prior opportunities to identify a

degraded fire door indicating personnel did not have a low threshold for identifying issues

(Inspection Report 05000483/2006005-01).

(b) Assessment - Effectiveness of Prioritization and Evaluation of Issues

The licensee did not always appropriately prioritize and evaluate conditions adverse to

quality. The team identified a large number of examples of poor evaluation that indicated

additional effort is needed in this area. Specifically, the team determined the licensee had:

two examples related to poor prioritization (E

xamples 1 and 3), two examples resulting from

personnel not fully implementing plant processe

s (Examples 2 and 8), one example of failure

to evaluate longstanding design issues (Example 6); and six examples that resulted from

ineffective evaluations (Examples 4, 5, 7, 9, 10 and 11). The team verified that the Callaway

Action Request screening process resulted in appropriately reassigning the significance level

of Callaway Action Requests commensurate with their safety significance (Example 12).

Similar to the last assessment, outside organizations continued to identify that the licensee

did not always perform effective evaluations

of conditions adverse to quality; consequently, the licensee continued to emphasize and prov

ide management oversight. The licensee had

implemented product quality evaluations in E

ngineering and had developed tools to evaluate,

- 7 - Enclosure

grade, and provide feedback on the Significance Level 1, Level 2 and selected Level 3

adverse condition Callaway Action Requests.

The team specifically evaluated the corrective

actions related to operability evaluations and

root cause evaluations, which the last biennial problem identification and resolution inspection

identified as deficient areas. The team concluded that the actions taken by the licensee (e.g.,

reinforced expectations, training of engineers and operators in design and license bases and

performance of operability evaluations, and impr

oved tiered root cause evaluation guidance)

had improved the quality of operability evaluations. However, the team determined the large

number of current examples for failure to adequately evaluate issues indicates the licensee

will need to take additional action in this area.

In response to external organization evaluations and as corrective action to the substantive

cross-cutting issue related to problem identification and resolution for inadequate evaluations

(refer to March 2, 2007, End of Cycle letter), the licensee initiated numerous actions to

strengthen the screening committee and other aspects of the corrective action program. A

majority of the actions related to reinforcing expected behaviors through coaching.

Current Issues

Example 1: As of December 19, 2007, the licensee had not tested the essential service

water, component cooling water and containment spray pumps at 20 percent of full flow.

Subsequently, the licensee invoked Surveillance Requirement 3.0.2 and completed the

testing within the extended 25 percent surveillance interval. While no violation of

requirements resulted, the licensee had not im

plemented the requirements in a timely

manner. The licensee documented this deficiency in Callaway Action Request 200801400.

Example 2: The resident inspectors determined the licensee performed an inadequate

post-maintenance test after repairing a damaged trip breaker contact block. Specifically,

personnel failed to identify that the contacts affected the P-4 interlock; consequently, the

licensee restored the breaker to service without performing a post maintenance test of the P-4

interlock. Although this test failed to meet the requirements of 10 CFR Part 50, Appendix B,

Criterion XI, the inspectors determined the violation was minor because the licensee

adequately tested the breaker prior to exceeding the Technical Specifications allowed outage

time. The licensee documented this deficiency in Callaway Action Request 200800811.

Example 3: Quality assurance auditors documented in Callaway Action Request 200711176

that personnel had not properly re-screened Significance Level 6 Callaway Action

Request 200700560 to an adverse condition Significance Level 4 nor was a new adverse

condition identified once personnel determined that external operating experience applied to

Callaway Plant. The team concluded the deficiency was minor since no identified deficiency

resulted from the review.

Example 4: Engineering approved deviating from

the established motor-driven auxiliary

feedwater pump coupling tolerances provided by

the vendor without considering the impact

on the thrust bearing (Inspection Report 05000483/2007004-02).

- 8 - Enclosure

Example 5: The resident inspectors determined that the licensee failed to evaluate the extent

of condition for micro-biologically induced corrosion of essential service water piping.

Specifically, the licensee failed to perform ultrasonic testing under the American Society of

Mechanical Engineers Code identification bands (Inspection Report 05000483/2007003-03).

Example 6: The resident inspectors determined that the licensee failed to evaluate a

longstanding ultimate heat sink cooling tower design issue, which resulted in allowing water to

flow over the fill below freezing conditions

contrary to vendor recommendations (Inspection

Report 05000483/2007003-01).

Example 7: The resident inspectors determined that the licensee failed to evaluate

micro-biologically induced corrosion of essential service water large-bore piping to ensure

the resolutions addressed causes and extent of condition (Inspection Report 05000483/2007002-03).

Example 8: After an operator could not locate a block switch during a surveillance test, the

control room supervisor revised the procedure without verifying the correct block switch

identifier. Consequently, during the test when the operator defeated the identified (wrong)

train block feature, the opposite rain control room ventilation isolated (Inspection

Report 05000483/2007002-01).

Example 9: Operations performed an inadequate review to establish compensatory actions of an

operator work around, which reflected a failure to thoroughly evaluate a problem to ensure

resolutions address causes and extent of condition (Inspection Report 5000483/2006005-05). Example 10

Engineering failed to thoroughly evaluate residual heat removal relief valve

problems to ensure resolutions addressed causes and extent of conditions (Inspection

Report 05000483/2006009-06).

Example 11

Callaway Action Request 200801664 described that personnel failed to document an adverse condition that required evaluation. Specifically, after Quality Assurance

identified in Audit AP06-003 that the turbine-

driven auxiliary feedwater pump exhaust line was

not adequately protected from missile hazards, Engineering initiated Request for

Resolution 2006006712; however, personnel failed to identify this as a potential

non-conforming condition in an adverse condition Callaway Action Request. Additionally, the

resident inspectors questioned if the current configuration was consistent with the licensing

basis.

Example 12

After reviewing significance level reassignments for Callaway Action Requests

that occurred during this assessment period, the team determined that the licensee had

appropriately classified the significance level for Callaway Action Requests and did not

identify a negative trend from this review. Specifically, for the population reviewed, the

licensee assigned a significance level to 65 items when no significance level had been

assigned, downgraded 25 items to a lower significance of which 15 received apparent cause

evaluations and 6 received a cause evaluation, and upgraded 53 items of which 34 received

cause evaluations.

- 9 - Enclosure

Historical Issues

Example 1: After questioning by the NRC, the licensee documented in Callaway Action

Requests 200609233 and 200500238 a less than adequate operability determination for a

degraded main steam isolation valve accumulator, which resulted in failure to implement the

required Technical Specification 3.7.2 actions (Inspection Report 05000483/2006012-03).

Example 2: The NRC determined that the licensee failed to properly evaluate and correct

inadequate emergency procedures for the design basis large break loss of coolant accident,

as documented in Callaway Action Requests 200602565 and 200608102. Specifically, the

licensee repeatedly missed opportunities that had presented themselves in Callaway Action

Requests, NRC findings, and vendor technical bulletins to uncover inadequate guidance in

Procedure E-1, "Loss of Reactor or Secondary Coolant" (Inspection

Report 05000483/2006011-01).

Example 3: The team determined that the licensee failed to evaluate all vulnerable

emergency core cooling system piping subject to voiding in response to a previous

NRC-identified violation for ineffective corrective actions. The team determined the licensee

failed to meet the requirements of 10 CFR Part 50, Appendix B, Criterion XVI. Specifically,

the licensee did not design and install vents for a significant length of horizontal piping subject

to the same deficiency and containing some high points, as documented in Callaway Action

Request 200608466 (Inspection Report 05000483/2006012-04)

Example 4: The Maintenance Rule Expert Panel failed to adequately review the failure of

safety-related motor-operated valves, which prevented thoroughly evaluating the problem to

ensure resolutions address causes and extent of conditions (Inspection

Report 05000483/2006005-02).

Example 5: Engineering performed an inadequate 10 CFR 50.59 safety evaluation, which

resulted in a less than thorough evaluation of the problem to ensure resolutions addressed

causes and extent of conditions (Inspection Report 05000483/2006005-04).

(c) Assessment - Effectiveness of Corrective Actions

The licensee implemented effective corrective ac

tions to address conditions adverse to

quality because of process improvements.

The team determined the improvements

addressed the weaknesses identified in the last biennial problem identification and resolution

inspection, as evidenced by only a single licens

ee-identified failure to implement effective

corrective actions. The team concluded that less than adequate past corrective action

program performance continued to result in the discovery of latent engineering issues; for

example, the ongoing challenges imposed by corrosion of the essential service water piping.

The team evaluated the planned actions for these corrosion deficiencies and concluded that

the licensee made appropriate operational decisions and took interim measures to ensure

that the system remained operable until the next refueling outage when they plan to

implement the permanent corrective actions.

The licensee had implemented a number of improv

ements in January 2007 that increased the

effectiveness of the corrective action program. The changes included, in part: (1) improved

definition of a condition adverse to quality in order to lower the threshold, (2) more categories

for adverse conditions to allow for broke-fix and relieve the burden of performing apparent

- 10 - Enclosure

causes for low significance conditions adverse to quality, (3) improved guidance for

performing cause evaluations, including a quality checklist, and (4) improved guidance for

performing immediate operability determinations. The team found that this approach ensured

the licensee applied the appropriate level of resources to identified issues commensurate with

their safety significance or impact on the facility. The team found the procedure guidance

clear, concise, and useful to personnel implementing the corrective action program. The

team determined that many of these changes should address some of the concerns identified

during this inspection.

Current Issues

Example: The licensee determined that they had implemented ineffective corrective actions

for Callaway Action Request 200609621, which documented that personnel had failed to

secure Fire Door DSK15031. The corrective action involved communicating the importance

of reading and abiding to posted signs related to closing fire doors. Subsequently, additional

instances of the improperly secured fire door occurred (i.e., Callaway Action

Requests 200702037, 200702596, 200706810, and 200707100). After the license initiated

corrective actions for Callaway Action Request 200702596, which involved locking the door

pin to prevent unauthorized unlatching of the Fire Door DSK15031 stationary door, the

licensee had discovered two additional instances prior to implementing the modification. This

licensee-identified performance deficiency is documented in Section 4OA7.

Historic Issues

Example 1: In Callaway Action Request 200609075, the licensee identified the failure to take

effective corrective actions in response to Callaway Action Request 200205928, which

documented missing sacrificial anodes in the emergency diesel generator heat exchangers.

The team determined the licensee had missed an opportunity to correct this deficiency in

October 2004. The failure to have all required sacrificial anodes installed was of minor safety

significance since the heat exchanger remained operable.

Example 2: Callaway Action Request 200602995 described that personnel implemented

inappropriate corrective actions for Callaway Action Request 200602565. Specifically, the

NRC determined that the licensee made an ineffective procedure change related to

establishing component cooling water flow to the residual heat removal heat exchangers prior

to swap over to the containment recirculation sumps. The procedure change failed to prevent

a potential runout condition for the component cooling water pumps (Inspection

Report 05000483/2006011-02).

b. Assessment of the Use of Operating Experience

(1) Inspection Scope

The team examined licensee programs for revi

ewing industry operating experience. The

team selected a number of operating experience notification documents (NRC bulletins,

information notices, generic letters, 10 CFR Part 21 reports, licensee event reports, vendor

notifications, et cetera), which had been issued during the assessment period, to verify

whether the licensee had appropriately evaluated each notification for relevance to the facility.

The team then examined whether the licensee had entered those items, which had been

deemed relevant, into their corrective action progr

am. Finally, the team reviewed a number of

- 11 - Enclosure

significant conditions adverse to quality and conditions adverse to quality to verify if the

licensee had appropriately evaluated them for industry operating experience.

(2) Assessment

The team identified some weakness in licensee evaluation and processing of operating

experience. Specifically, failure to appropr

iately evaluate industry operating experience

contributed to two findings in this area. The team documented Example 1, which related to

untimely evaluation of applicable operating experience, in this inspection report. The team

determined that Example 2 documents failure to

effectively evaluate operating experience

because the licensee did not consider all areas subject to flooding. Any finding that results

from the failure to perform an appropriate flood analysis will be documented in the resident

inspector integrated report. The team determined that the licensee continued to effectively

assess industry operating experience during root cause and apparent cause evaluations of

significant conditions adverse to quality and conditions adverse to quality, respectively.

Current Issues

Example 1: The team determined that the licensee failed to determine in a timely manner

whether the acceptance criteria for Technical Specification Surveillance Requirement 3.8.4.5

demonstrated that the NK11 and NK14 safety-related batteries could meet the design

requirements. The licensee initiated Callaway Action Request 200706268 in response to

operating experience on July 10, 2007. The

licensee inappropriately requested extension

requests to complete their evaluation such that they had operated with this non-conservative

Technical Specification until challenged by the team (refer to Section 4OA2.e).

Example 2: In Callaway Action Requests 200502989 and 200607843, the licensee concluded

that the flooding analysis summary took no credit for flooding in areas above the lower levels

in each building. The team considered the evaluation inadequate because several flooding

analyses credit floor drains at elevations other than the basement. For example,

Calculation M-FL-07, "Flooding of the Aux Bldg Rms EL. 2047'6"," evaluated the impact of

flooding in the Control Room heating, ventilation and air conditioning room.

Historical Issues

Example: The licensee's corrective measures inappropr

iately used instrument uncertainty to

increase design margin (Inspection Report 05000483/2006009-05).

c. Assessment of Self-Assessments and Audits

(1) Inspection Scope

The team reviewed numerous audits, self-assessments, quality surveillances, and site

performance indicators. The team reviewed

program procedures and interviewed process

managers related to the performance improvem

ent group, the corrective action program, and

the Quality Assurance department. The team

evaluated the use of self- and third party

assessments, the role of Quality Assurance, and the role of the performance improvement

group related to licensee performance.

- 12 - Enclosure

(2) Assessment

The licensee continued to perform self-critical assessments, audits and evaluations. The

team noted that the factors that influenced the improvement identified during the last

corrective action program evaluation continued dur

ing this assessment period. Specifically,

the licensee used directed assessments to evaluate suspect or known areas of weakness.

The licensee implemented the recommendations and

findings of external self-assessments

that they requested. The licensee established processes to ensure increased management

oversight at all levels in the organization related to improved worker performance, adherence

to procedures, and conduct of root cause analyses.

Quality Assurance performed critical, detailed audits and surveillances of line

organizations (Example 2). The audit performance criteria had goals of excellence (e.g., third

party expectations and NRC inspection guidance) rather than compliance. The team

determined that the line organizations continued to use audits and surveillances as a tool to

improve their performance. For example, Qua

lity Assurance performed three surveillances of

critical activities related to the corrective actions planned for the essential service water

system corrosion issues (Example 1).

The team verified that the licensee implemented performance indicators and trended data that

should allow the managers to evaluate the progress of their actions to improve performance

related to human performance and corrective action program deficiencies.

The licensee performed several self-assessments related to safety culture during this

assessment period. The team evaluated the self-assessments and concluded that the

licensee conducted critical evaluations of their safety culture and the safety conscious work

environment (Examples 3 and 4). The licensee initiated Callaway Action Request 200800944

to perform a higher tier apparent cause evaluation and to ensure that they addressed the

assessment recommendations. Recommendations included developing a differing

professional opinion process, developing a process to review proposed disciplinary actions

and performing benchmarking of other programs.

Current Issues

Example 1: Quality Assurance performed several critical surveillances related to corrosion in

the essential service water system, which related to the examination scope of the piping, the

repairs of the affected piping, and the suitability to operate during Cycle 16.

Example 2: Audit AP07-013, "Corrective Action Program

," provided critical evaluations of the corrective action program areas that previously had problems, which included operability

evaluations, prioritization, and management oversight. The team verified that the line

organization had implemented appropriate corrective actions to address the numerous

adverse conditions identified in the audit.

Example 3: The licensee performed a Synergy Safety

Culture Assessment in February 2007.

The Safety Culture Survey included an assessment of the general culture and work

environment and the safety conscious work envir

onment. The safety culture survey identified

that the licensee had significant challenges related to resources/work load and change

management that affected the trust of the workers in management. The survey identified that

no chilling effect or safety conscious work environment concerns existed. However, the

- 13 - Enclosure

results indicated, the general culture and work environment concerns could affect the nuclear

safety culture and the safety conscious work

environment, if not addressed by management.

Example 4: Because of the large number of allegations at the facility in Calendar Year 2007, the licensee requested an independent assessment to evaluate their safety conscious work

environment in February 2008. The assessment determined that the licensee had maintained

a safety conscious work environment and that no chilled work environment existed. The

assessment team concluded work environment

and corrective action program issues had the

potential, if not addressed, to erode the willingness of individuals to bring issues forward

using the corrective action program.

d. Assessment of Safety Conscious Work Environment

(1) Inspection Scope

The team evaluated this area by reviewi

ng self-assessments and audits, interviewing

personnel regarding the safety conscious work environment at Callaway Plant using the

questions provided in Inspection Procedure 71152B, and interviewing the Employee

Concerns Coordinator. Specifically, the

team reviewed the Independent Assessment of the

Callaway Plant Safety Conscious Work Environment performed in February 2008, the 2007

Safety Culture Assessment, and three department

specific safety culture assessments.

The team conducted formal interviews with 93 personnel in response to the large number of

allegations received at Callaway Plant, which had identified concerns with the safety

conscious work environment. Normally, the inspection interviews 15 - 25 personnel. The

team conducted the interviews with plant personnel to assess their willingness to raise safety

issues and use the corrective action program. Further, the team assessed whether conditions

existed that would challenge the establishment

of a safety-conscience work environment.

The team documented the details of the review in Attachment 3, "Concerns Evaluated." Note:

Examples 1 - 5 below have correspondi

ng numbers in Attachment 3.

(2) Assessment

From interviews and review of safety con

scious work environment assessments, the team

determined that the licensee maintained a safety conscious work environment. However,

there were some issues identified that were outside NRC regulatory jurisdiction that, if not

addressed by the licensee, could potentially affect

the safety conscious work environment at

the Callaway Plant. Overall, interviewed employees felt free to enter issues into the

corrective action program as well as, raise nuclear safety concerns to their supervision, the

employee concerns program, and the NRC.

During interviews, personnel generally

expressed confidence that the licensee had established an appropriate threshold for

documenting nuclear safety issues and that iss

ues entered into the corrective action program

would be appropriately addressed.

The 2007 Safety Culture Assessment concluded that the licensee, generally, has a solid

safety culture and that site personnel have nuclear safety as a core value. However, the

safety culture assessment identified several groups that required additional attention. The

assessment also identified areas that management needed to address related to the general

culture and work environment that incl

uded implementing appropriate change management, better management of resources, workload, staffing and priorities. The team verified that the

- 14 - Enclosure

licensee had initiated Callaway Action Requests and had implemented appropriate corrective

actions for the identified deficiencies.

Consistent with the 2005 Safety Culture A

ssessment, the 2007 Safety Culture Assessment,

and the February 2008 Safety Conscious Work Environment self-assessment, the team

determined that, generally, employees express

ed willingness to use the corrective action

program and raise nuclear safety concerns. The team determined that not all individuals

were comfortable using all of the methods available to them for reporting concerns; however,

all personnel would have used at least one of the methods available for reporting a safety

concern. Also, the licensee continues to have challenges related to visibility of the Employee

Concerns Program and the willingness of some people to use the Employee Concerns

Program (Examples 2 and 3).

In response to numerous concerns (Examples 1 - 3) the team evaluated whether the licensee

encourages personnel to identify problems. The team determined that management

encourages personnel to identify problems and raise concerns using the corrective action

program or through discussions with their supervisor. The team determined from this sample

that no chilled work environment existed at Callaway Plant. However, within the security

department, some individuals would not raise personal concerns. From review of two

technical concerns (Examples 4 and 5), the team determined that the licensee had resolved

the issues commensurate with their safety significance and regulatory requirements.

Current Issues

Example 1: The team evaluated whether the licensee had established a culture where

personnel did not feel comfortable raising concerns and where management did not want to

hear about problems. The team determined that management encouraged personnel to raise

concerns. During interviews, all personnel indicated that they would raise nuclear safety

concerns; however, some personnel indicated that they would not raise personal issues

unrelated to nuclear safety because they belie

ved that management would take no actions.

Example 2: The team evaluated how employees us

ed the employee concerns program. The

team determined that most, but not all, em

ployees would use the employee concerns

program if they did not get satisfaction from us

e of the corrective action program or from their

supervisor. However, two individuals did not trust the employee concerns program and would

rather talk to the NRC. The team determined that 30 percent of the personnel interviewed

had a misconception of the employee concerns program (e.g., did not know the program

coordinator had changed, did not know the purpose of the employee concerns program, did

not know the location of the coordinator's office, et cetera).

Example 3: The team evaluated whether a chill

ed work environment existed in any

department but focused particularly in the training, radiation protection, operations and

security organizations. From the interviews, the team determined that all individuals would

raise concerns by using one of the four methods - corrective action program, supervisor,

employee concerns program, or NRC. However, the team determined that not all individuals

would use all of the methods. Specifically, one indi

vidual would only talk with their supervisor.

Example 4: The team reviewed whether the licensee timely resolved the condition that

damaged to the residual heat removal pump suction relief valves. The licensee missed an

opportunity to correct the error in March 2007 when a design error identified by a vendor

- 15 - Enclosure

prevented issuing the modification in time for implementation. The team verified that the

licensee scheduled the modification for Refueling Outage 16 in October 2008. No violation

resulted since the licensee will implement the

modification commensurate with its safety

significance.

Example 5: The team reviewed whether the licensee took the appropriate actions to not

pursue a license amendment specifically prohibiting plant operation with both cold

overpressure mitigation systems out of service

with the reactor coolant system solid. Since

the licensee had no shutdown probabilistic safety analysis, the team could not quantitatively

determine whether it was safer to operate without cold overpressure mitigation system valves

under solid plant conditions or saturated plant conditions. Further, the team determined that

the licensee took appropriate actions to request an extension of the period allowed for

establishing a reactor coolant system vent path from 8 to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Example 6: As discussed in the example in Section 4OA2.a(2)(a), security officers had

identified that a specific security feature generated excessive nuisance alarms. The team

determined that the licensee had initiated Callaway Action Requests related to other security

organization issues that included a safety hazard while performing patrols and a health

hazard. The team determined during interviews that these deficiencies did not affect the

willingness of security officers to report deficiencies to their supervisor or to use the corrective

action program.

e. Specific Issues Identified During This Inspection

Introduction. The team identified a Green noncited violation of 10 CFR Part 50, Appendix B, Criterion III, "Design Control," because the licensee failed to ensure that Technical

Specification Surveillance Requirements for the NK11 and NK14 safety-related batteries

established limits that met the design requirements. Specifically, until questioned by the team

the licensee failed to determine the required design value needed to assure plant safety. The

licensee determined that 69 micro-ohms should be the actual allowed inter-cell voltage limit to

meet the design requirements versus an allowed Technical Specification limit of

150 micro-ohms.

Description. The team reviewed Callaway Action Request 200706561 that the licensee

initiated July 10, 2007, to evaluate the adequacy of Technical Specifications 3.8.4 and 3.8.5

for the NK11 and NK14 safety-related batteries. The licensee initiated Callaway Action

Request 200706561 because external industry operating experience had identified that some

licensees had not documented the basis for the 150 micro-ohm limit specified in Technical

Specification Surveillance Requirements 3.8.4.2 and 3.8.4.5 and, in some cases, challenged

the operability of the safety-related batteries when the limit was applied to each inter-cell

connection. Callaway Action Request 200706561, Action 4 requested an evaluation to

determine the appropriate maximum inter-cell resistance value for station batteries. The team

determined that the licensee had not completed their evaluation of Surveillance

Requirements 3.8.4.2 and 3.8.4.5 at the time of the inspection.

The team determined that Procedure APA-ZZ-01400, Attachment 4, "Industry Operating

Experience Screening Committee Guidelines," Section 4.b, states that Operating Experience

Callaway Action Requests should be assigned due dates not to exceed 60 days to ensure a

timely determination of plant impact. The team determined that, while the licensee had

assigned a completion date within 60 days, personnel had obtained several extensions that

- 16 - Enclosure

prevented assessing the significance or facility impact within the initial 60 days specified in

Procedure APA-ZZ-01400. Consequently, these ext

ensions delayed evaluating Surveillance

Requirements 3.8.4.2 and 3.8.4.5. Following discussion with the team, the licensee

evaluated the current design assumptions in Calculation NK-05, "Class 1E Battery Capacity,"

Revision 6, which the licensee had used to size the NK11 and NK14 safety-related batteries.

The licensee's evaluation found that the licensee based the battery sizing on an end

discharge voltage of 108.6 volts correlating to a maximum inter-cell resistance of 86.1

micro-ohms. Since the 86.1 micro-ohms limit

was less than that allowed by Surveillance

Requirements 3.8.4.2 and 3.8.4.5 (indicating a nonconservative Technical Specification), the

licensee performed an additional calculation to determine an appropriate inter-cell resistance

to support battery operations. Upon completing Calculation NK-10, "NK11 Accident Case,"

Revision 1, the licensee would need to limit the maximum inter-cell resistance to

69 micro-ohms to assure battery operability.

Following discovery of the non-conservative inter-cell resistance, the licensee performed a

prompt operability determination and concluded the NK11 and NK14 safety-related batteries

remained operable since past surveillances had measured inter-cell resistances well below

69 micro-ohms. The licensee implemented compensatory measures as described in NRC

Administrative Letter 1998-10, "Dispositioning of Technical Specifications That Are Insufficient

to Assure Plant Safety," to assure the new inter-cell resistance limit of 69 micro-ohms would

not be exceeded. The licensee intended to continue the interim compensatory measures until

they revised their Technical Specifications.

Analysis. The performance deficiency associated with this finding involved the failure to

ensure that the NK11 and NK14 safety-related batteries would remain operable if all the

inter-cell connections measured 150 micro-ohms as allowed by Technical Specification

Surveillance Requirements 3.8.4.2 and 3.8.4.5. This finding was greater than minor because

it was associated with the Mitigating Systems cornerstone attribute of maintenance and

testing and affects the associated cornerstone objective to ensure the availability, reliability,

and capability of systems that respond to initiating events to prevent undesirable

consequences. Using Manual Chapter 0609.04, "Phase 1 - Initial Screening and

Characterization of Findings," the finding was determined to have very low safety significance

because it was a design deficiency confirmed not to result in loss of operability. The finding

had a crosscutting aspect in the area of problem identification and resolution associated with

operating experience because the licensee failed to

evaluate in a timely manner relevant

internal and external operating experience P.2(a).

Enforcement. Title Ten Code of Federal Regulations Part 50, Appendix B, Criterion III, "Design Control," requires, in part, that the licensee establish measures to assure that

applicable regulatory requirements and the design basis for structures, systems and

components are correctly translated into specifications, drawings, procedures, and

instructions. Additionally, design control measur

es shall provide for verifying or checking the

adequacy of design, such as by the performance of design reviews, by the use of alternate or

simplified calculation methods, or by the performance of a suitable testing program. Contrary

to the above, prior to March 13, 2008, the licensee failed to verify that the 150 micro-ohm

criterion specified in Surveillance Requirement 3.8.4.2 and 3.8.4.5 would be sufficient to

ensure safety-related battery operability in accordance with the design basis. Once

challenged, the licensee determined that a maximum inter-cell resistance of 69 micro-ohm

could not be exceeded to ensure the battery remained operable. This finding is of very low

safety significance and has been entered into the corrective action program as Callaway

- 17 - Enclosure

Action Request 200802195, this violation is being treated as a noncited violation consistent

with Section VI.A of the NRC Enforcement Policy: NCV 05000483/2008006-01,

"Nonconservative Technical Specification for battery inter-cell connection resistances."

4OA6 Exit Meeting

On March 14, 2008, the team presented their inspection results to Mr. A.C. Heflin, Vice

President, and other members of his staff who acknowledged the findings. The inspectors

returned all proprietary and confidential information provided during the inspection.

4OA7 Licensee Identified Violations

The following violation of very low safety significance (Green) was identified by the licensee

and is a violation of NRC requirements that meets the criteria of Section VI of the NRC

Enforcement Policy, NUREG-1600, for being dispositioned as a noncited violation.

Technical Specification 5.4.1.d requires that AmerenUE maintain a fire protection program.

Procedure APA-ZZ-0071, "Control of Impairments of Fire Protection Systems and

Components," requires personnel to maintain the integrity of plant fire doors. Contrary to this,

security officers identified during routine tours on March 6, March 20, July 18, and

July 31, 2007, which personnel failed to maintain the integrity of Fire Door 15031. This

licensee documented these deficiencies in Callaway Action Requests 200702037, 200702596, 200706810, and 200707100, respectively. This finding is of very low safety

significance because the exposed fire area contained no potential damage targets that are

unique from those in the exposing fire area.
