- LaSalle County Station, Units 1 and 2; Evaluations of Changes, Tests, or Experiments and Permanent Plant Modifications.
This report covers a two-week announced baseline inspection on evaluations of changes, tests, or experiments and permanent plant modifications. The inspection was conducted by Region III based engineering inspectors.
Based on the results of this inspection, one Severity Level IV violation was identified by the inspectors. The findin g was considered a Non-Cited Violation (NCV) of NRC regulations. The significance of the majority of findings are indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process" (SDP).
Cross-cutting aspects were determined using IMC 0310, "Components Within the Cross-Cutting Areas." Findings for which the SDP does not apply may be Green or may 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.
A.
Cornerstone: Initiating Events
N RC-Identified and Self-Revealed Findings Severity Level IVThe inspectors determined that the violation was more than minor because the finding, if left uncorrected would become a more significant safety concern. Iin addition, the inspector could not reasonably determine that the changes would not have ultimately required NRC prior approval. The inspectors determined that the finding was of very low safety significance (Green) based on a review of the licensee's operability determination and corrective actions for non-conformance to the ASME code requirements issues identified since the deletion of the TRM section. The inspectors determined that the licensee's actions in the four instances did not have any technical safety concerns. This finding had a cross-cutting aspect in the area of Human Performance within the Decision Making component because the licensee did not use conservative assumptions to ensure the proposed activity was safe. Specifically, the licensee mad e an inadequate assumption when they determined that the removal of TRM, Section 3.4.a did not have an adverse effect. H.1(b). (Section 1R17.1.b)
- The inspectors identified a Severity Level IV Non-Cited Violation and an associated finding of very low safety significance (Green) of 10 CFR 50.59, "Changes, Tests, and Experiments," Section (d)1 for the licensee's failure to perform a written safety evaluation to demonstrate that the deletion of the Technical Requirements Manual (TRM), Section 3.4.a did not require a license amendment. The licensee entered this issue into their Corrective Action Program and initiated a Standing Order reinstating the TRM Section 3.4.a. B. No violations of significance were identified.

a. Evaluation of Changes, Tests, or Experiments From September 4, 20 12 through September 21, 2012, the inspectors reviewed seven safety evaluations performed pursuant to Title 10, Code of Federal Regulations (CFR) 50.59 to determine if the evaluations were adequate and that prior NRC
-approval was obtained as appropriate. The inspectors also reviewed seventeen screenings where licensee personnel had determined that a 10 CFR 50.59 evaluation was not necessary. The inspectors reviewed these documents to determine if:
Inspection Scope the changes, tests, or experiments performed were evaluated in accordance with 10 CFR 50.59 and that sufficient documentation existed to confirm that a license amendment was not required; the safety issue requiring the change, tests or experiment was resolved; the licensee conclusions for evaluations of changes, tests, or experiments were correct and consistent with 10 CFR 50.59; and the design and licensing basis documentation was updated to reflect the change.
The inspectors used, in part, Nuclear Energy Institute (NEI) 96
-07, "Guidelines for 10 CFR 50.59 Implementation," Revision 1, to determine acceptability of the completed evaluations, and screenings. The NEI document was endorsed by the NRC in Regulatory Guide 1.187, "Guidance for Implementation of 10 CFR 50.59, Changes, Tests, and Experiments," dated November 2000. The inspectors also consulted Part 9900 of the NRC Inspection Manual, "10 CFR Guidance for 10 CFR 50.59, Changes, Tests, and Experiments."
This inspection constituted seven samples of evaluations and seventeen samples of changes as defined in IP 71111.17-04. b.
.1 Findings Introduction
- The inspectors identified a Severity Level IV, NCV of 10 CFR 50.59(d)(1), "Changes, Tests, and Experiments," and an associated finding of very low safety significance (Green
) for the licensee's failure to perform a safety evaluation to demonstrate that the removal of the TRM Section 3.4.a did not require a license amendment. Specifically, the licensee did not adequately address the adverse effects of the changes in their screening L09-240. This inadequate screening resulted in the adverse changes not being evaluated under 10 CFR 50.59 change evaluation criteria.Failure to Perform a Written Safety Evaluation for TRM Changes:
3 Enclosure Description
- Technical Requirements Manual Section 3.4.a. addressed structural integrity requirements for the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (Code) Class 1, 2, and 3 components of the Reactor Coolant System (RCS) including surveillance requirements to verify structural integrity in accordance with the In
-Service Inspection/Testing Program. This section also prescribed specific actions with corresponding completion times if the structural integrity of an ASME Code Class 1, 2 or 3 component was found not to be in conformance with the requirements of the Code. The actions included either restoring the component within its limit or isolating it. These requirements were previously stated in Technical Specification (TS) Section 3/4.4.8, before it was relocated to the TRM as a part of the LaSalle Station's Technical Specifications conversion to the Improved Technical Specifications (ITS). The license amendment specified that the change control process for the new TRM requirements Section 3.4.a. was 10 CFR 50.59.
The licensee deleted Section 3.4.a and the corresponding section in the bases from the TRM in 2009 using the 10 CFR 50.59 process per screening L09
-240. The licensee concluded that the change did not have an adverse effect based on a justification that the TRM requirements were a duplicate to the requirements in 10 CFR 50.55a and were being implemented through the requirements in Technical Specification 5.5.7 for the In-Service Testing Program. Based on the justifications used in screening L09
-240 , the licensee screen ed out the change as not needing a full safety evaluation and consequently not needing NRC prior approval. The licensee
's screening also concluded that actions taken, following deletion of the TRM section, for a component found not meeting the structural integrity acceptance criteria was not change d. Specifically, if ASME Code requirements were not met, the impact to system operability and/or functionality would be assessed as a nonconforming condition, in accordance with the Corrective Action Program. The operability of the Structures, Systems, and Components (SSC) would be determined in accordance with the TS definition of operability for TS SSCs or functionality for non TS SSCs following the guidance in Operation Procedure (OP)-AAA-108-115, "Operability Determinations." The inspectors determined, based on a review of the licensee's procedures for corrective actions and operability determinations, that following these procedures would not result in the same actions as those described in the deleted section of the TRM. The inspectors were concerned that for component s found in non
-conformance, the TRM Section 3.4.a require d either restoring the structural integrity within its limits or isolating the components, whereas , the use of the operability determination process could allow the licensee to continue operations without isolating the non-conforming component. The inspectors were concerned that these actions were not covered under 10 CFR 50.55a
, and therefore , in some cases the deletion of the TRM actions could result in an adverse effect on the component reliability. Consequently, since the deletion of the TRM actions resulted in adverse effects, this change required a 50.59 safety evaluation.
Licensee's Procedure LS
-AA-104-1000, 50.59 Resource Manual required that if a change has both positive and adverse effects, the change should be screened in, thus requiring a 50.59 safety evaluation. These procedural requirements are consistent with the Nuclear Energy Institute (NEI) 96
-07, Revision 1, "Guidelines for 10 CFR 50.59 Implementation."
Based on the above, the inspectors determined that the licensee failed to appropriately evaluate the differences between the actions required per the deleted TRM Section 3.4.a and the new process. Specifically, the licensee failed to 4 Enclosure appropriately evaluate the se differences in a safety evaluation or obtain an NRC prior approval/licensee amendment.
The licensee entered the deficiency in their Corrective Actions Program as Action Request (AR) 1416141 and initiated a Standing Order reinstating TRM Section 3.4.a. until identifying the appropriate action for final disposition of this issue.
Analysis:
The inspectors determined that the failure to provide a written safety evaluation to demonstrate that the deletion of TRM Section 3.4.a did not require a licensee amendment was contrary to the requirements of 10 CFR 50.59(d)(1)and was a performance deficiency because an adequate screening would have identified the requirement to perform a safety evaluation. The inspectors determined that the finding was more than minor because the finding, if left uncorrected, would become a more significant safety concern.
Specifically, the deletion of the TRM Section 3.4.a could result in components not meeting the acceptance criteria for structural integrity being left in service, thereby adversely affecting reliability of the RCS components. The inspectors concluded this finding was associated with the Initiating Events Cornerstone.
In addition, the associated violation was determined to be more than minor because the inspectors could not reasonably determine that the changes would not have ultimately required NRC prior approval
. Violations of 10 CFR 50.59 are dispositioned using the traditional enforcement process instead of the significance determination process (SDP) because they are considered to be violations that potentially impede or impact the regulatory process. This violation is associated with a finding that has been evaluated by the SDP and communicated with an SDP color reflective of the safety impact of the deficient licensee performance. The SDP, however, does not specifically consider the regulatory process impact.
Thus, although related to a common regulatory concern, it is necessary to address the violation and finding using different processes to correctly reflect both the regulatory importance of the violation and the safety significance of the associated finding
. In this case, the inspectors determined that the finding could be evaluated using the SDP in accordance with IMC 0609, "Significance Determination Process."
Using Attachment 0609.04, "Initial Characterization of Findings," Table 2, the inspectors determined that the finding affected the Initiating Events cornerstone.
As a result, the inspectors evaluated the finding using Appendix A, "The Significance Determination Process (SDP) for Findings At-Power," Exhibit 1 for the Initiating Events cornerstone.
The inspectors answered "NO" to the first two questions in Exhibit 1.
Specifically, the inspectors determined that the finding could n ot result in exceeding the leak rate for a small LOCA and it could n ot have likely affected other systems used to mitigate a LOCA resulting in a total loss of their function , and therefore
, the inspectors screened the finding as Green.
This was based on the inspectors
' review of the four Action Reports issued since the TRM change implementation documenting the non
-conforming conditions related to structural integrity of the ASME components.
Specifically, in two instances the affected components were isolated, in one instance where the leak was not isolable, the plant was brought to cold shutdown as required by the Technical Specifications for implementation of repair, and the remaining case was found to be in compliance with the code on further evaluation.
5 Enclosure In accordance with Section 6.1.d of the NRC Enforcement Policy this violation is categorized as Severity Level IV because the resulting changes were evaluated by the SDP as having very low safety significance (i.e., Green finding).
The inspectors determined that the associated finding had a cross-cutting aspect in the Decision Making component of the Human Performance cross
-cutting area because the licensee did not use conservative assumptions to ensure nuclear safety. Specifically, the licensee's failure to perform a safety evaluation was the result of a non
-conservative assumption that the TRM requirements were duplicate to the 10 CFR 50.55a; and therefore, the changes did not have an adverse effect even though the specific required actions listed in the deleted section of the TRM were not included in the new process for addressing structural integrity related non
-conformances.
H.1(b) Enforcement
- Title 1 0 CFR 50.59 Section (d)(1) requires, in part , that the licensee maintain records of changes in the facility, of changes in procedures, and of tests and experiments. These records must include a written evaluation which provides the bases for the determination that the change, test, or experiment does not require a license amendment pursuant to Paragraph (c)(2).
Contrary to the above, on December 23, 2009 , the licensee failed to perform a written safety evaluation to demonstrate that the deletion of TRM Section 3.4.a did not require a license amendment. Specifically, the licensee did not adequately address the adverse effects of the changes in their screening L09-240. This inadequate screening resulted in the adverse changes not being evaluated under 10 CFR 50.59 change evaluation criteria.
The violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy because it was of very low safety significance and was entered into the licensee's Corrective Action Program (AR 1416141
). (NCV 05000373/2012007-01; 05000374/2012007
-01; Failure to Perform a Written Safety Evaluation for TRM Changes
). The associated finding is evaluated separately from the traditional enforcement violation
- and therefore, the finding is being assigned a separate Tracking Number (FIN 05000373/2012007-02; 05000374/2012007
-02; Failure to Perform a Written Safety Evaluation for TRM Changes
).
.2 a. Permanent Plant Modifications
From September 4, 2012 through September 21, 2012, the inspectors reviewed seven permanent plant modifications that had been installed in the plant during the last three years. This review included in
-plant walkdowns for portions of the Engineering Change (EC) 383736 "SBLC Test Seismic Fix;" and EC 353398 "Design and Install AB
-TB HELB Barrier." The modifications were selected based upon risk significance, safety significance, and complexity. The inspectors reviewed the modifications selected to determine if: Inspection Scope the supporting design and licensing basis documentation was updated; the changes were in accordance with the specified design requirements; the procedures and training plans affected by the modification have been adequately updated; the test documentation as required by the applicable test programs has been updated; and post-modification testing adequately verified system operability and/or functionality.
The inspectors also used applicable industry standards to evaluate acceptability of the modifications. The list of modifications and other documents reviewed by the inspectors is included as an Attachment to this report.
This inspection constituted seven permanent plant modification samples as defined in IP 71111.17-04. b. No findings of significance were identified.
