INSPECTION RESULTS
Failure to Maintain Fire Protection Compensatory Measures During Control Room Ventilation Isolation Signal Actuation Cornerstone Significance Cross-Cutting Aspect Report Section Mitigating Systems Green NCV 05000482/2023002-01 Open/Closed None (NPP)71111.05 The inspectors identified a Green finding and associated non-cited violation of technical specification 5.4.1.d, for the licensees failure that written procedures shall be maintained covering fire protection program implementation. Specifically, the licensee failed to maintain Procedure AP 10-103, Fire Protection Impairment Control, revision 39, which required a fire compensatory measure to maintain engineered safety feature switchgear rooms A and B halon system functional during a control room ventilation isolation actuation.
Description:
The inspectors reviewed the licensees Updated Safety Analysis Report (USAR),normal operating procedures, and surveillance procedures for the control room ventilation isolation signal (CRVIS) and the fire protection program. Specifically, the inspectors reviewed surveillance Procedure STS GK-005A, Control Room Ventilation Isolation Response Time Test - Train A, revision 2, and Procedure AP 10-100, Fire Protection Program, revision 25, and identified the following:
The licensees fire protection program uses a defense-in-depth approach to fire protection to ensure that the plant can be safely shut down and public health and safety is maintained in the event of a fire. This protection is accomplished through automatic detection and suppression systems, trained personnel, fire emergency procedures, and administrative controls.
Procedure AP 10-100 provides the list of procedures for the licensees fire protection program. These procedures implement the fire protection program as described in the USAR which included:
o Procedure AP 10-103, Fire Protection Impairment Control, revision 39, defines the compensatory measures required for out-of-service or degraded fire protection features.
o Off normal Procedure OFN KC-016, Fire Response, revision 52, was developed to provide instructions for establishing response to, control of, and recovery from fire events.
o Alarm response Procedure ALR KC-888, Fire Protection Panel KC-008 Alarm Response, revision 33, provides control room personnel with basic instructions for responding to each alarm, instructions for clearing the alarm, and a list of the field instruments which could generate the alarm.
Procedure STS GK-005A manually initiates train A(B) CRVIS by depressing the actuate pushbutton on SA HS-9(13), which controls building ventilation train A(B) isolation. This inserts the CRVIS signal and opens control room filtration system A(B) supply dampers. If control room filtration system supply dampers are closed with a CRVIS signal present, they will reopen once their associated close signal is removed. The only way to maintain the supply dampers closed is to reset the CRVIS signal prior to closing them or remove power from the dampers prior to removing the close signal by removing control power fuses in the control room. However, during an engineered safety feature (ESF) switchgear room fire, the control room radiation monitor lost power and both trains of CRVIS will actuate and seal in.
Therefore, the only way to ensure the control room filtration system A(B) supply dampers remain closed was to remove power to maintain the ESF switchgear room A and B halon boundary in event of the fire. This is due to one of two control radiation monitor loss of power and causing a CRVIS actuation that cannot be reset. The licensee did have guidance in their normal operating Procedure SYS GK-122, Manual CRVIS Line-Up, revision 25, to remove power from the control room filtration system supply dampers by removing fuses. However, SYS GK-122 was not referenced in procedures STS GK-005A, AP 10-103, ALR KC-888, and OFN KC-016. Additionally, SYS GK-122 was not referenced as one of the procedures that implements the licensees fire protection program in accordance with procedure AP 10-100.
The licensee would have to rely on operator knowledge during ESF switchgear room fire to identify the need to use the guidance in SYS GK-122.
From the above, the inspectors determined the compensatory measure for the ESF switchgear rooms degraded halon barrier during CRVIS in accordance with procedure AP 10-103, attachment E, was not maintained. Specifically, the licensee failed to remove power from the control room filtration system A(B) supply dampers by removing fuses prior to releasing GK HIS-83 or 160 close pushbuttons to maintain the ESF switchgear room A and B halon boundary. The inspectors informed the licensee of the issue. The licensee then entered it into their corrective action program as condition reports 10023674 and 10023797.
Corrective Actions: The licensee established required reading for maintaining the control room filtration system A(B) supply dampers closed in case of a fire in the ESF switchgear and updated procedures AP 10-103, ALR KC-888, and OFN KC-016.
Corrective Action References: Condition reports 10023674 and 10023797
Performance Assessment:
Performance Deficiency: The licensees failure to maintain procedure AP 10-103, attachment E, compensatory measure for maintaining the ESF switchgear rooms A and B halon system functional during CRVIS actuation was a performance deficiency.
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the protection against external factors attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the licensee failed to maintain compensatory measures for maintaining the ESF switchgear rooms halon boundary functional during CRVIS actuation in the event of a fire.
Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix F, Fire Protection and Post - Fire Safe Shutdown [Safety Determination Process]
SDP. The inspectors assigned the finding a fire Category 1.4.1 using Inspection Manual Chapter 0609, Appendix F, Attachment 1, Fire Protection Significance Determination Process Worksheet, dated May 2, 2018, because the finding involved fire prevention and administrative controls. The inspectors determined that the finding had very low safety significance (Green) because the finding:
- (1) did not increase the likelihood of a fire, delay detection of a fire, or resulted in a more significant fire than previously analyzed such that credited safe shutdown strategy could be adversely impacted; and
- (2) the degraded fire confinement element continued to provide adequate fire endurance to prevent fire propagation through the fire confinement element given the combustible loading and location of equipment important to safe shutdown in the fire area of concern.
Cross-Cutting Aspect: Not Present Performance. Specifically, the performance deficiency occurred in 2003 when the licensee incorporated operating experiences associated with fire occurring in the ESF switchgear rooms when performing CRVIS surveillance testing.
Enforcement:
Violation: Technical specification 5.4.1.d requires that written procedures shall be established, implemented, and maintained covering fire protection program implementation.
Procedure AP 10-103, Fire Protection Impairment Control, revision 39, attachment E defines the compensatory measures required for out-of-service or degraded fire protection features.
Contrary to the above, the licensee failed to maintain procedures covering the fire protection program implementation. Specifically, from January 2004 to May 2023, as defined in procedure AP 10-103, attachment E, the licensee failed to maintain compensatory measures to ensure control room filtration supply dampers remained closed to maintain ESF switchgear rooms A and B halon system function during CRVIS actuation.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with section 2.3.2 of the Enforcement Policy.
Failure to Implement Emergency Exhaust System Surveillance Testing Procedure Cornerstone Significance Cross-Cutting Aspect Report Section Barrier Integrity Green NCV 05000482/2023002-02 Open/Closed
[H.5] - Work Management 71111.13 The inspectors identified a Green finding and associated non-cited violation of technical specification 5.4.1.e, for the licensees failure that written procedures shall be implemented for Technical Specification 5.5.11, Ventilation Filter Testing Program (VFTP). Specifically, the licensee failed to properly implement surveillance Procedure STS PE-006, Charcoal Adsorber In-Place Leak Test Safety Related Units, revision 17, when establishing the prerequisites for performing train A emergency exhaust system in-place leak testing of the charcoal absorber causing train B emergency exhaust system to become inoperable when an operator opened the wrong breaker.
Description:
On May 16, 2023, the inspectors performed a walkdown of train A emergency exhaust system to verify the licensee established surveillance Procedure STS PE-006, Charcoal Adsorber In-Place Leak Test Safety Related Units, revision 17, prerequisites.
During this walkdown, the inspectors identified the licensee failed to correctly implement surveillance procedure STS PE-006. Specifically, the licensee failed to open the train A emergency exhaust system humidity control heating coil breaker. Instead, the licensee opened the train B emergency exhaust system humidity control heating coil breaker and caused train B emergency exhaust system to become inoperable for approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. The licensee entered this issue into their corrective action program and performed an event review.
The inspectors perform a walkdown of train B emergency exhaust system and reviewed the event review and concluded the licensee failed to implement the work management process.
The key items that resulted in this violation included:
The licensee protected train B emergency exhaust system with the exception of the motor control center containing train B emergency exhaust systems humidity control heating coil breaker. The reason the licensee protected train B emergency exhaust system was, because on May 15, 2023, train A emergency exhaust system was declared inoperable for a failed surveillance test.
The licensee designated the incorrect steps as not applicable prior to implementing surveillance procedure STS PE-006. Specifically, the licensee designated steps to open train A emergency exhaust system humidity control breaker as not applicable, instead of train B emergency exhaust system humidity control breaker.
The licensee failed to verify job site conditions for train A emergency exhaust system prior to commencing surveillance procedure STS PE-006, as required by step 7.9.2.
Specifically, the licensee failed to verify the train A emergency exhaust system humidity control breaker was open prior to the inspectors identifying the breaker was not open. The inspectors identified the incorrect breaker was opened, because they questioned why the train A emergency exhaust system humidity control heat coiling status lights where on when power to the unit was removed in accordance with STS PE-006.
The licensee failed to ensure the individual from the operational relief crew was fully aware of plant status associated with train A emergency exhaust system being inoperable and train B emergency exhaust system being protected.
Corrective Actions: The licensee restored train B emergency exhaust system operability by closing its humidity control heating coil breaker and performed train A emergency exhaust system past operability evaluation, and determined it was operable during the time emergency exhaust system B was inoperable.
Corrective Action References: Condition report 10024447
Performance Assessment:
Performance Deficiency: The licensees failure to open the train A emergency exhaust system humidity control heating coil breaker, and instead opened train B emergency exhaust system humidity control heating coil breaker, which caused inoperability for train B emergency exhaust system, was a performance deficiency.
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the human performance attribute of the Barrier Integrity cornerstone and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Specifically, the licensees failure to open the correct breaker during train A emergency exhaust system surveillance testing resulted in train B emergency exhaust system being inoperable for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.
Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Using Exhibit 3, Section C, the inspectors determined the finding was of very low safety significance (Green) because it only represented a degradation of the radiological barrier function of the auxiliary and fuel buildings.
Cross-Cutting Aspect: H.5 - Work Management: The organization implements a process of planning, controlling, and executing work activities such that nuclear safety is the overriding priority. The work process includes the identification and management of risk commensurate to the work and the need for coordination with different groups or job activities. Specifically, the licensee failed to effectively plan and execute work by incorporating risk insights, job site conditions, the need for coordination with different groups, and to ensure individuals were aware of plant status, the nuclear safety risks associated with work in the field.
Enforcement:
Violation: Technical specification 5.4.1.e. requires that written procedures shall be established, implemented, and maintained covering all programs specified in Technical Specification 5.5, which includes Technical Specification 5.5.11, Ventilation Filter Testing Program (VFTP). The licensee established surveillance Procedure STS PE-006, Charcoal Adsorber In-Place Leak Test Safety Related Units, revision 17, to perform in-place leak testing of the auxiliary/fuel building emergency exhaust system charcoal absorber.
Contrary to the above, on May 16, 2023, the licensee failed to properly implement written procedures specified in technical specification 5.5.11. Specifically, during the performance of surveillance procedure STS PE-006, the licensee opened the incorrect breaker rendering train B emergency exhaust system inoperable.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with section 2.3.2 of the Enforcement Policy.
Observation: Semiannual Trend Review 71152S The inspectors reviewed the licensees corrective action program, performance indicators, system health reports, and other documentation available to help identify performance trends that might indicate the existence of a more significant safety issue. The inspectors verified that the licensee was taking corrective actions to address the identified adverse trends. The inspectors did not review any cross-cutting themes because none existed at the site.
To verify the licensee was taking corrective actions to address identified adverse trends that might indicate the existence of a more significant safety issue, the inspectors noted a trend in human performance. Specifically, the inspectors noted ten condition reports from April 5, 2023, to May 26, 2023, associated with human performance events. Examples included:
Condition report 10024172: The licensee identified, during the performance of quality assurance assessment QA-2023-0581, a trend associated with procedure adherence with information use procedures.
Condition report 10024176: The licensee identified the incorrect sample location was used for sampling the spent fuel pool. The licensee sampled from normal location instead of the alternate location for when the refueling water storage tank was aligned for recirculation. The licensee failed to verify procedure prerequisites are met rather than assuming they are met based on general plant conditions.
Condition report 10024432: The licensee identified an individual verified the incorrect breaker during clearance order verification. The licensee failed to perform an adequate pre-job brief, perform a thorough review of the work site, human error reduction tool usage.
Condition report 10024447 and NCV 2023002-02: The inspectors identified the licensee failed to properly implement surveillance procedure STS PE-006, Charcoal Adsorber In-Place Leak Test Safety Related Units, revision 17, when establishing the prerequisites for performing train A emergency exhaust system in-place leak testing of the charcoal absorber causing train B emergency exhaust system to become inoperable when an operator opened the wrong breaker.
Condition report 10024456: The licensee identified train A essential service water pump missed surveillance. The train A essential service water pump was placed on an increased frequency (every 45 days) to perform vibration measures due to being in the alert range in accordance with the ASME OM Code. However, the licensed failed to perform the surveillance at 45 days due to not having a consistent process for changing surveillance frequency in accordance with the ASME OM Code.
Condition report 10024699: The licensee tripped emergency diesel generator A during post-maintenance testing due to not nulling the voltage regulatory prior to placing it into manual. The licensee failed to use human error reduction tools and the latent condition contained with the procedure where multiply actions are contained in one step.
Condition report 10024701: The licensee identified the failure to declare the train A offsite circuit inoperable and missed surveillance requirement 3.8.1.1 when the emergency diesel generator A was paralleled with the offsite circuit and safety feature transformer A load tap changer was in automate. This occurred during post-maintenance testing of emergency diesel generator A. The procedure did not discuss the technical specification requirements associated with the safety-related transformer load tap changer in automatic and the impact on the offsite circuit.
Condition reports 10024329, 10024630, and 10023626: The inspectors identified three examples of the licensee failure to implement procedure AI 22C-013, Protected Equipment, revision 3. Specifically, two examples associated with not protecting equipment required by AI 22C-013 (H.8 Procedure Adherence) and one example of not determining if additional equipment was needed to be protected during technical specification equipment outages due to change in which work group performs the step.
In response to the above trend, the licensee issued site-wide communications, individual corrective actions, and performed a trend analysis documented in condition report
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
On June 8, 2023, the inspectors presented the radioactive effluent and environmental monitoring inspection results to J. McCoy, Site Vice President, and other members of the licensee staff.
On July 6, 2023, the inspectors presented the integrated inspection results to J. McCoy, Site Vice President, and other members of the licensee staff.
