LASALLE COUNTY STATION NRC INSPECTION REPORT 50-373/02-11(DRS);50-374/02-11(DRS)
Dear Mr. Skolds:
On September 27, 2002, the NRC completed an inspection at your LaSalle County Station, Units 1 and 2. The enclosed report documents the inspection findings, which were discussed on September 27, 2002, with Mr. G. Barnes and other members of your staff.
The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.
The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel. Specifically, this inspection focused on the design and performance capability of the emergency diesel generators and their support systems to ensure that they were capable of performing their required safety-related functions. In addition, the inspection reviewed a sample of permanent plant modifications and changes made under 10 CFR 50.59.
Based on the results of this inspection, the inspectors identified three issues of very low safety significance (Green) that were determined to involve violations of NRC requirements. However, because of their very low safety significance and because they were entered into your corrective action program, the NRC is treating the issues as Non-Cited Violations in accordance with Section VI.A.1 of the NRC s Enforcement Policy. If you deny these Non-Cited Violations, in whole or in part, you should provide a response with a basis for your denial, within 30 days of the date of this inspection report, to the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001, with copies to the Regional Administrator, Region III; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the LaSalle County Station. In accordance with 10 CFR 2.790 of the NRCs Rules of Practice, a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

SUMMARY OF FINDINGS
IR 05000373/02-11(DRS), IR 05000374/02-11(DRS); Exelon Generation Company, LLC; on 09/09-27/02, LaSalle County Station; Units 1 & 2. Safety System Design and Performance Capability Inspection.
The inspection was a three week baseline inspection of the design and performance capability of the emergency diesel generators and associated support systems. In, addition, the biennial review of permanent plant modifications and 10 CFR 50.59 evaluations was concurrently performed. The inspection was conducted by regional engineering specialists, with mechanical consultant assistance. The inspection identified three issues of very low significance. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter 0609, Significance Determination Process (SDP). Findings for which the SDP 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 3, dated July 2000.
Inspection Findings
Cornerstone: Mitigating Systems
- Green.
The inspection team identified a Non-Cited Violation (NCV) of 10 CFR Part 50,
Appendix B, Criterion III, Design Control, that applied to the air start systems for all the emergency diesel generators on both units. Specifically, the inspectors identified that the design basis requirement that the starting air systems have enough air to permit either five (Division 1 and 2 diesel generators) or three (Division 3 diesel generators) normal starts in rapid succession was not translated into specifications, procedures, and instructions. As a result, there was no objective evidence that the required starting air system capacity was being maintained.
The finding was greater than minor based on the potential that degradation of the design basis capability of a starting air system would not be detected by the licensee. Degradation of the design function impacts the base probabilistic risk assessment values used for diesel generator reliability. The finding was of low safety significance because it does not represent an actual loss of the starting air system safety function. (Section 1R21.1)
- Green.
The inspection team identified an NCV of 10 CFR Part 50, Appendix B, Criterion III, that applied to the fuel oil storage tanks for the high pressure core spray diesel generators on both units. Specifically, the inspectors identified that the licensee had incorrectly calculated the necessary volume for the fuel oil storage tanks.
The finding was greater than minor based on the number of deficiencies associated with the diesel generator fuel storage tank capacities requiring preparation of new calculations and corrections to existing calculations, the updated final safety analysis report, the technical specification bases, to procedures, and, possibly, to the technical specifications themselves.
The finding was of low safety significance because it did not represent an actual loss of the high pressure core spray diesel generator fuel oil storage volume as currently required by technical specifications. Furthermore, in the unlikely event that extended operation of the diesel generators was necessary, the licensee would likely be able to get fuel on site before the end of the seven day period. (Section 1R21.2)
- Green.
The inspection team identified an NCV of 10 CFR Part 50, Appendix B, Criterion III, that applied to all the emergency diesel generators on both units. The test control valves on the diesel heads of all five emergency diesels were replaced by valves having a different form, fit, and function. The licensee did not ensure that the change was commensurate with the original design.
The finding was greater than minor because it involved the licensee failing to implement a required regulatory process. The finding was of low safety significance because of a warning currently in the licensees procedure and the fact that the valves are only opened during surveillance. (Section 1R21.2)

1R02 Evaluations of Changes, Tests, or Experiments
Review of Evaluations and Screenings for Changes, Tests, or Experiments
a. Inspection Scope
The inspectors reviewed twelve 10 CFR 50.59 evaluations and eleven screenings.
These documents were reviewed to ensure consistency with the requirements of 10 CFR 50.59. The inspectors used Nuclear Energy Institute (NEI) 96-07, Guidelines of 50.59 Evaluations, 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, November 2000. The inspectors also consulted Inspection Manual, Part 9900, 10 CFR GUIDANCE: 50.59. Documents reviewed during the inspection are listed at the end of the report.
b. Findings
No findings of significance were identified.
1R17 Permanent Plant Modifications
Review of Recent Permanent Plant Modifications
a. Inspection Scope
The inspectors reviewed five permanent plant modifications that were performed by the licensee's engineering staff during the last two years, all but one of which affected the emergency diesel generators or their associated support systems. Therefore, review of the modifications counted for completion of activities under both NRC Inspection Procedures 71111, Attachments 17 and 21. The modifications were reviewed to verify that the completed design changes were in accordance with specified design requirements and the licensing bases and to confirm that the changes did not affect the modified system or other systems' safety function. Calculations which were performed or revised to support the modifications were also reviewed. As applicable to the status of the modification, post-modification testing was reviewed to verify that the system, and associated support systems, functioned properly and that the modification accomplished its intended function. The inspectors also verified that the completed modifications did not place the plant in an increased risk configuration. The inspectors evaluated the modifications against the licensee's design basis documents and the updated final safety analysis report (UFSAR). The inspectors also used applicable industry standards, such as the American Society of Mechanical Engineers Code, to evaluate acceptability of the modifications.
b. Findings
No findings of significance were identified.
1R21 Safety System Design and Performance Capability
Introduction Inspection of safety system design and performance verifies the initial design and subsequent modifications and provides monitoring of the capability of the selected systems to perform design bases functions. As plants age, the design bases may be lost and important design features may be altered or disabled. The plant risk assessment model is based on the capability of the as-built safety system to perform the intended safety functions successfully. This inspectable area verifies aspects of the mitigating systems cornerstone for which there are no indicators to measure performance.
The objective of the safety system design and performance capability inspection is to assess the adequacy of calculations, analyses, other engineering documents, and operational and testing practices that were used to support the performance of the selected systems during normal, abnormal, and accident conditions. The inspection was performed by a team of inspectors that consisted of a team leader, three Region III inspectors, and two mechanical consultants.
The systems selected for review during this inspection were based upon:
- having a high probabilistic risk analysis ranking;
- having had recent significant issues;
- not having received recent NRC review; and
- being interacting systems.
The systems selected were the emergency diesel generators (including the high pressure core spray diesel), and their support systems: diesel generator cooling water, diesel fuel oil and diesel starting air.
The criteria used to determine the systems performance included:
- applicable technical specifications;
- applicable UFSAR sections; and
- the systems' design documents.
The following system and component attributes were reviewed in detail:
System Requirements Process Medium - water, fuel oil, electricity Energy Source - electrical power, fuel oil, air Control Systems - initiation, control, and shutdown actions Operator Actions - initiation, monitoring, control, and shutdown System Condition and Capability Installed Configuration - elevation and flow path operation Operation - system alignments and operator actions Design - calculations and procedures Testing - flow rate, pressure, temperature, voltage, and levels Components The common
- (0) diesel generator cooling water pump was selected for detailed review during the inspection. This component was specifically reviewed for component degradation due to the impact that its failure would have on the plant.
.1 System Requirements
a. Inspection Scope
The inspectors reviewed the updated final safety analysis report, technical specifications, system descriptions, drawings and available design basis information to determine the performance requirements of the emergency diesel generators and their associated support systems. The reviewed system attributes included process medium, energy sources, control systems, and operator actions. The rationale for reviewing each of the attributes was:
Process Medium: This attribute required review to ensure that the emergency diesel generators would supply the required loads following design basis events. To achieve this function, the inspectors also verified that the fuel oil system would transfer sufficient oil to maintain diesel operability, that the diesel generator cooling water system would transfer sufficient heat to maintain diesel operability, and that the air intake and exhaust system provided sufficient oxygen to support combustion.
Energy Sources: This attribute needed to be reviewed to ensure that the emergency diesel generators and associated support systems would start when called upon, and that appropriate valves would have sufficient power to change state when so required.
To achieve this function, the inspectors verified that the interactions between the diesel generators and their support systems were appropriate such that all components would start when needed.
Controls: This attribute required review to ensure that the automatic controls for starting the diesel generators, and associated systems, were properly established.
Additionally, review of alarms and indicators was necessary to ensure that operator actions would be accomplished in accordance with the design.
Operations: This attribute was reviewed because the operators took a number of actions during the monthly and quarterly surveillance tests that had the potential for affecting diesel generator automatic operation. In addition, the operating procedures for loss of offsite power or loss of vital boards permitted the operators to manually load the diesel generators with non-safety related loads. Therefore, operator actions played an important role in the ability of the emergency diesel generators and associated support systems to achieve their safety related functions.
b. Findings
Introduction:
Green. The inspectors identified a Non-Cited Violation (NCV) of 10 CFR Part 50, Appendix B, Criterion III Design Control, that applied to the air start systems for all of the emergency diesel-generators on both units. Specifically, the inspectors identified that the design bases for each of the Division 1, 2, and 3 emergency diesel-generator starting air systems were not translated into specifications, procedures, and instructions. As a result, there was no objective evidence that the required emergency diesel generator starting air system capacity was being maintained.
Discussion: The design basis for the air start system, as stated in the UFSAR and technical specification bases, is to have sufficient air to allow five normal starts in rapid succession (three starts for the high pressure core spray (HPCS) diesels) without use of the air compressors and with an initial air pressure of 200 psig. At the beginning of the inspection, the inspectors requested the calculations that sized the system. The licensee was not able to locate these analyses during the inspection, and determined that no calculations existed. The licensee stated the air start system was bought as a pre-specified unit and was tested during preoperational testing. The licensee provided copies of the preoperational tests which showed that the air start systems met the design basis at the time the plant was licensed. However, the inspectors noted several discrepancies between the preoperational and current conditions which could not be readily explained and which called into question the ability of the system to meet its design basis function.
The inspectors noted that, during the preoperational tests for Divisions 1 and 2, each bank of air experienced, on average, a 13 to 17 psig drop for the initial start. Recent Division 1 and 2 starts typically averaged an 18 to 22 psig drop. This would indicate that more air was being used per start and that the design basis might not be maintained.
For Division 3, a similar increase from 25 to 30 psig during preoperational testing to 30 to 35 psig during current testing was observed. However, it was not possible to make a direct comparison between the data for two reasons:
- (1) The preoperational tests were conducted using a single air bank while the tests at the time of the inspection used both banks (due to an unrelated abutment issue). The licensee provided some informal data, not regularly taken during the surveillance testing, that showed that the cranking time for the air start system had decreased since the time of the preoperational tests. The inspectors agreed that the cranking times had slightly decreased over time, as would be expected with the change to dual bank starts. However, while this data could show that the air start system was still accelerating the engine to 150 rpm in the same (or less) time, it could not explain the increased air usage. Furthermore, because the data was not consistently taken, the inspectors did not believe that it could be credited for showing that the design basis was properly translated into procedures.
- (2) The preoperational tests were conducted at 200 psig, while the current tests are conducted between 225 to 240 psig. Due to the licensee switching to starting on both air banks, the procedure requires the operators to drain the tanks down and allow them to refill if the tanks are more than five pounds off. This is done in order to ensure that both banks start at about the same pressure. Attempts, by both the inspectors and the licensee, to correlate the increased pressure drop to the increased starting air pressure were unsuccessful. The licensee prepared engineering change 338926; however after discussion with the inspectors, they withdrew it and planned to revise it.
Analysis:
Evaluation of this issue concluded that it is a design control deficiency resulting in a finding of very low safety significance (Green). The design control deficiency is due to the licensee neither having design calculations available that documented the starting air system design requirements, nor having testing acceptance criteria which would show that the design basis capability of the air start system was being maintained. The mitigating systems cornerstone was affected due to the potential undetected degradation of the design basis capability of a starting air system, with the associated potential effect on the starting capability for the emergency diesel-generator and on equipment that would be powered by the emergency diesel-generator. No other cornerstones were determined to be degraded as a result of this issue.
This finding was determined to be greater than minor based on the potential that degradation of the design basis capability of a starting air system would not currently be detected by the licensee. The design basis capability of the emergency diesel-generator starting air system was based on the capability to provide five (three) fast starts in rapid succession without the use of the starting air system compressor, with a minimum air receiver pressure of 200 psig.
Degradation of the design function impacts the base probalistic risk assessment values used for diesel generator reliability.
This finding was assessed as Green because it does not represent an actual loss of the starting air system safety function. Surveillance testing from preoperational/start-up tests to the most recent fast starts has demonstrated the current operability of the diesel generators to start within the required 13 seconds. Therefore, this issue was screened out of the significance determination process as Green.
Enforcement:
10 CFR Part 50, Appendix B, Criterion III, Design Control, states, in part, that measures be established to assure that applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures, and instructions.
Contrary to the above, as of September 27, 2002, the design basis for the emergency diesel-generator starting air systems was not correctly translated into plant documents, in that design calculations were not available and acceptance criteria were not included in surveillance and testing procedures to verify that the starting air system design basis capability was maintained. The licensee initiated condition report 124743 to address this issue.
Because of the low safety significance of this issue and because it is in the licensees corrective action program, the issue is being treated as a Non-Cited Violation, consistent with Section VI.A.1 of the NRC Enforcement Policy (NCV 50/373-2002-011-01; 50/374-2002-011-01).
.2 System Condition and Capability
a. Inspection Scope
The inspectors reviewed design basis documents and plant drawings, abnormal and emergency operating procedures, requirements, and commitments identified in the updated safety analysis report and technical specifications. The inspectors compared the information in these documents to applicable electrical, instrumentation and control, and mechanical calculations, setpoint changes and plant modifications. The inspectors also reviewed operational procedures to verify that instructions to operators were consistent with design assumptions.
The inspectors reviewed information to verify that the actual system condition and tested capability was consistent with the identified design bases. Specifically, the inspectors reviewed the installed configuration, the system operation, the detailed design, and the system testing, as described below.
Installed Configuration: The inspectors confirmed that the installed configuration of the emergency diesel generators and associated support systems met the design basis by performing detailed system walkdowns. The walkdowns focused on the installation and configuration of piping, components, and instruments; the placement of protective barriers and systems; the susceptibility to flooding, fire, or other environmental concerns; physical separation; provisions for seismic and other pressure transient concerns; and the conformance of the currently installed configuration of the systems with the design and licensing bases.
Operation: The inspectors performed procedure walk-throughs of selected manual operator actions to confirm that the operators had the knowledge and tools necessary to accomplish actions credited in the design basis. Additionally, the inspectors attended a simulator walk-through for selected diesel generator loading sequences.
Design: The inspectors reviewed the mechanical, electrical and instrumentation design of the emergency diesel generators and associated support systems to verify that the systems and subsystems would function as required under accident conditions. The review included a review of the design basis, design changes, design assumptions, calculations, boundary conditions, and models as well as a review of selected modification packages. Instrumentation was reviewed to verify appropriateness of applications and set-points based on the required equipment function. Additionally, the inspectors performed limited analyses in several areas to verify the appropriateness of the design values.
Testing: The inspectors reviewed records of selected periodic testing and calibration procedures and results to verify that the design requirements of calculations, drawings, and procedures were incorporated in the system and were adequately demonstrated by test results. Test results were also reviewed to ensure automatic initiations occurred within required times and that testing was consistent with design basis information.
Pre-operational test data was also reviewed to confirm initial design parameters that could not be tested under normal operations.
b. Findings
===.1
Introduction:
=
Green. The inspectors identified a second NCV of Criterion III that applied to the fuel oil storage tanks for the HPCS diesel generators on both units. Specifically, the inspectors identified that the licensee had incorrectly calculated the necessary volume for the fuel oil storage tanks.
Description:
Per the UFSAR, Section 9.5.4.2, the licensee is committed to American National Standard Institute (ANSI) N195-1976, Fuel Oil Systems for Standby Diesel-Generators, Section 5 (System Performance Requirements), Subsection 5.4 (Calculation of Fuel Oil Storage Requirements). Subsection 5.4 requires licensees to calculate the total fuel storage requirements based on calculating the expected time dependent loads, plus a ten percent margin. The standard also provides a conservative alternative for calculating the storage capacity by assuming that the diesel operates continuously for seven days at its rated capacity.
For the Division 1 and 2 diesel generator fuel oil storage tanks, the licensee chose to calculate the storage capacity by assuming that the diesels operated continuously at their rated capacities. For the Division 3 diesels, the licensee chose to determine a time-dependent load and to calculate the tank capacity on that basis.
The inspectors noted a number of problems associated with fuel oil storage tank and fuel consumption calculations. For example, the inspectors identified that the values in calculation DO-14 were based on a presumption that the HPCS pump would go to runout after a day and would remain in that condition. Furthermore, the calculation did not take into account the ten percent margin required by the ANSI standard.
Additional problems noted were:
- Calculation DO-7 appeared to have been superceded, at least in part, by calculations DO-11 and DO-14. However this wasnt recognized in any fashion.
- Similarly, calculation DO-8 was partially superceded by DO-13 and DO-15.
- Technical Specification 3.8.1.4 was non-conservative in relation to the design basis as described in calculation DO-15. The licensee concluded there was no operability problem as the tanks were always maintained above the low level setpoint and the DO-15 calculations were determined to be overly conservative.
- Procedure LOP-DO-02 contained errors related to incorrect diesel fuel oil transfer pump auto trip and auto start volume levels.
- There were no calculations to support the tables converting tank height in inches of water to gallon of fuel oil. These tables were posted on the doors of each day tank room and were included in procedures LOP-DO-01 and LOP-DO-02.
- UFSAR Table 8.3-1 had not been revised to correctly reflect the values in design calculation 4266/19AK19. In addition, the licensee did not have a calculation for the scenario of a loss of coolant accident on Unit 2 with a shutdown on Unit 1, even though that would result in a different loading on the 0 diesel generator than the case analyzed in 4266/19AK19.
- The loading calculated in 4266/19AK19 was 2717 kilowatts, which was well above the continuous loading of 2660 kilowatts, although within the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> loading. Procedure LOA-AP-101 did not contain any restrictions on loading the diesel generators, which negated the conservatism assumed in ANSI N-195.
Analysis:
Evaluation of this issue concluded that it is a design control deficiency resulting in a finding of very low safety significance (Green). The design control deficiency existed in that the licensee had not included the ANSI N-195 minimum margin of ten percent above the load profile results in the design calculations and subsequently had not translated adequate design basis requirements into specifications, procedures, and instructions to meet the licensees UFSAR commitment. The mitigating systems cornerstone was affected due to the failure to include adequate margin in the design basis minimum storage requirements for the HPCS emergency diesel generator fuel oil storage volume, with the associated potential effect of the inability of the storage volume to supply operation of each HPCS emergency diesel generator for the full seven day interval at the assumed loadings. This potential effect would impact the emergency diesel generator as well as the equipment that it would power during the seven day design interval. No other cornerstones were determined to be degraded as a result of this issue. Degradation of the design function impacts the base probalistic risk assessment values used for diesel generator reliability.
This finding was determined to be greater than minor based on the number of deficiencies associated with the diesel generator fuel storage tank capacities. These deficiencies will require preparation of new calculations, corrections to existing calculations, the UFSAR, the technical specification bases, and to procedures.
Changes to the technical specifications themselves may also be required. Therefore the criteria for a more than minor violation of design control was deemed to be met.
This finding was assessed as Green because it did not represent an actual loss of the HPCS diesel generator fuel oil storage volume as required by technical specifications.
Furthermore, the inspectors recognized that, in the unlikely event that extended operation of the diesel generators was necessary, the licensee would be able to get fuel on site before the end of the seven day period.
Enforcement:
10 CFR Part 50, Appendix B, Criterion III, Design Control, states, in part, that measures be established to assure that applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures, and instructions.
Contrary to the above, the licensee had not included the ANSI N-195 minimum margin in the design calculations of minimum HPCS emergency diesel generator fuel oil storage volume and subsequently had not translated adequate design basis requirements into specifications, procedures, and instructions to meet the licensees FSAR commitment.
The licensee initiated condition reports for each of the above problems during the inspection to address associated problems. A complete list of condition reports can be found in the list of documents at the end of the report.
Because of the very low safety significance of this issue and because the issues have been entered into the licensee's corrective action program, the finding is being treated as a Non-Cited Violation, consistent with Section VI.A.1 of the NRC Enforcement Policy (NCV 50/373-2002-011-02; 50/374-2002-011-02). This issue was determined to be sufficiently different from the issue on the air start system system such that it should be considered a separate violation rather than a separate example of a violation.
2.
Introduction:
Green. The inspectors identified an NCV of 10 CFR Part 50, Appendix B, Criterion III that applied to all of the emergency diesel generators on both units. The licensee replaced the vent control valves on the diesel generator heads with valves having different form, fit and function and did not apply a design control process commensurate to the original design.
Discussion: During a walkdown of the emergency diesel generators, the inspectors noted pressure test connection valves on the diesel cylinder heads that appeared different from the original. The licensee confirmed that the valves had been modified so the inspectors requested copies of the design change documents used for the installation of the equipment. The licensee responded that the valves were installed using the alternate parts replacement program. After some discussion, copies of the alternate parts replacement records and appropriate procedures were obtained.
During visual examination of the old and new valves, review of the alternate parts evaluation and review of the current surveillance procedure, the inspectors determined that the old and new valves had substantial differences and actually performed different functions. Therefore, the use of the alternate parts evaluation, where the part was assumed to have the same basic form, fit, and function, was not appropriate.
The inspectors noted that the original needle valve stem had to be completely removed to allow connection of test equipment. Once testing was completed, the test connections had to be removed, the valve stem installed and hand tightened in a clockwise direction to prevent flow. The replacement required an adapter for installation into the head. The valve then fitted onto the top of the adaptor and functioned as most valves, where the stems are not removed during operation. Instead a handwheel was turned to rotate the valve disc off its seat and allow flow to the test equipment, which could remain connected no matter the position of the valve. Another important difference introduced by this change in valve design was that the stem was required to be rotated clockwise for opening and counter clockwise for closing. This was different, not only from the original design, but also from the opening and closing of most valves.
Based on the documents reviewed, the inspectors concluded that a type of failure, not previously identified (i.e., ejection of the valve adapters), could have occurred with this type replacement valve. During discussions, licensee personnel stated that such an incident had occurred around 1998 at another plant where a cylinder test valve adapter was ejected from a diesel resulting in the inoperability of the diesel. The information had been distributed as industry experience type information. As a result of the industry experience notification, the licensee revised its procedures to add a warning to ensure that the valves were not over tightened.
Analysis:
Evaluation of this issue concluded that it was a design control deficiency resulting in a finding of very low safety significance. The design control deficiency was due to the licensee having failed to control the design modification process to the same degree as the original design. Because the licensee installed the new valves as an alternate parts replacement, a 10 CFR 50.59 screening or evaluation was not performed and drawings and procedures were not updated.
Because the licensee identified the potential for a new failure mode associated with this modification (as evidenced by warning in the surveillance procedures), the inspectors reviewed the issue against the requirements of 10 CFR 50.59 and discussed this issue with the cognizant individual in the Office of Nuclear Reactor Regulation for issues regarding 10 CFR 50.59. In either 1994 or 1998, the wording of 10 CFR 50.59 would have required the licensee to have submitted the modification for NRC review and approval, presuming the licensee had recognized at that time that a different failure mode had been introduced into the system.
However, in March 2001, a revised version of 10 CFR 50.59 took effect. The revised version permits changes to be made that introduce new failure modes, as long as those new failure modes do not result in "more than a minimal increase in the likelihood of a malfunction of equipment important to safety." Based upon the current warning in the licensees procedure and the fact that the valves are only opened during surveillances, the inspectors concluded that the modification would not result in more than a minimal increase and that the issue did not require further NRC review.
Enforcement:
10 CFR Part 50, Appendix B, Criterion III, Design Control, states, in part, that measures be established to assure that applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures, and instructions. It further states that design changes shall be subject to design control measures commensurate with those applied to the original design.
Contrary to the above, in December 1994, when the new valves were installed, the licensee did not apply the design change process commensurate with the original design in that they did not perform a 10 CFR 50.59 screening or evaluation nor did they update operating procedures or drawings. This led to a potential new failure mode not being evaluated properly. Because the issue involved a failure to implement a required regulatory process, application of the significance determination process was not appropriate. However, after consultation with NRC management, it was determined that the issue was of very low risk significance and should be assigned a color of "Green."
Because of the low safety significance of this issue and because it is in the licensees corrective action program, the issue is being treated as a Non-Cited Violation, consistent with Section VI.A.1 of the NRC Enforcement Policy (NCV 50/373-2002-011-03; 50/374-2002-011-03). The licensee entered this into their corrective action program as condition report 124850.
.3 Components
a. Inspection Scope
The inspectors examined the 0 diesel generator cooling water pump to ensure that component level attributes were satisfied. The attribute selected for review was component degradation, due to the impact that the pumps failure could have on the diesel generator.
Component Degradation: This attribute was verified through review of component repair histories and review of corrective action documents. The inspectors reviewed the attribute to verify the licensee was appropriately maintaining components in the emergency diesel generators and associated support systems
b. Findings
No findings of significance were identified.
OTHER ACTIVITIES (OA)
4OA2 Identification and Resolution of Problems
a. Inspection Scope
The team reviewed a sample of emergency diesel generator and associated support system problems that were identified by the licensee and entered into the corrective action program. The inspectors reviewed these issues to verify an appropriate threshold for identifying issues and to evaluate the effectiveness of corrective actions related to design issues.
