71111.05

The inspectors identified a Green finding and associated non-cited violation (NCV) of License

Condition 3.I, Fire Protection, associated with the licensee's failure to implement and maintain

in effect, the provisions of the approved fire protection program as described in the Updated

Final Safety Analysis Report (UFSAR), which resulted in a non-conservative calculation for

the low-pressure carbon dioxide system for the Unit 1 and Unit 2 cable vaults.

Description: On August 24, 2023, the inspectors performed a walkdown of the Unit 1 cable

vault, Fire Zone 1, elevation 15 feet. The inspectors identified several penetrations on the

west wall that were not sealed. The licensee determined that the unsealed penetrations on

the west wall led to a void space between the Unit 1 cable vault and the Unit 1 safeguards

building basement. The west wall (or false wall) leading to the void space is not an

Appendix R fire barrier but was being credited as a boundary for the low-pressure carbon

dioxide system for the cable vault. The Appendix R fire barrier is the wall between the Unit 1

cable vault void space and the Unit 1 safeguards building. The concern is that carbon dioxide

could leak into the void space and impact the ability of the low-pressure carbon dioxide

system to perform its function to suppress deep seated fires in the cable vault.

Calculation CE-1853, Volumes of Requested Rooms, was used to determine the volume of

the cable vault but did not include the volume of the void space. In 2008, the results from CE-

1853 were used as a design input in Calculation ME-0828, Cable Vault and Tunnel

Calculations for Surry Units 1 and 2 Fire Protection, which resulted in a non-conservative

calculation. Calculation ME-0828 determined that the total carbon dioxide required to

suppress a fire in the Unit 1 cable vault, accounting for known leakage paths, was 4262

pounds. ME-0828 stated that the amount of carbon dioxide supplied was 4271 pounds. This

results in a positive margin of 9 pounds. However, if ME-0828 is adjusted to include the

volume of the void space, approximately 1000 cubic feet, the minimum carbon dioxide

required would result in a deficit (negative margin) of 74 pounds.

Additionally, on August 24, 2023, while following up on the issue identified by the inspectors,

the licensee identified a penetration in the Unit 1 safeguards building basement that was not

sealed. The degraded penetration was located on the fire barrier wall between the Unit 1

safeguards building basement and the Unit 1 cable vault void space. This degraded

penetration is dispositioned as a licensee-identified violation in the Inspection Results section

of this report. The issue is noted here since the as-found condition, as identified by the

inspectors, could have resulted in the loss of carbon dioxide not only to the void space but

through the void space to the Unit 1 safeguards building basement. The licensee repaired the

degraded penetration on the Unit 1 safeguards building basement fire barrier; however, the

inspectors took this degraded condition into account in determining the significance of the

finding associated with the non-conservative Calculation ME-0828.

The licensee declared the carbon dioxide system for the Unit 1 cable vault non-functional and

established an hourly fire watch in accordance with Technical Requirements Manual (TRM)

3.7.8. The licensee reviewed Calculation ME-0828 and identified conservatisms associated

with the conversion factor for carbon dioxide loss rate, an error in the total height of the

volume of the cable vault, and CO2 actual discharge time versus the designed requirement

time. The licensee identified enough conservatisms in the calculation to confirm functionality

of the Unit 1 cable vault low-pressure carbon dioxide system with the volume of void space

included in the total cable vault volume and exited TRM 3.7.8. Including the degraded

conditions identified by the inspectors and the licensee, the revised preliminary calculation

resulted in 76 pounds of carbon dioxide supplied above the required amount.

On August 28, 2023, the licensee performed an extent of condition review in the Unit 2 cable

vault and identified similar conditions and performed similar actions as for Unit 1.

The inspectors concluded that the licensee did not maintain Calculation ME-0828 in

accordance with the requirements of CM-AA-CLC-301, Engineering Calculations, Attachment

1, Fundamental Expectations, which stated, in part, that assumptions shall be justified and

bounded by the station design basis. The design bases layout of the void space is detailed in

Drawing 11448-FC-24D, Plan and Details, Elevation 15 feet - 0 inches, Auxiliary Building.

The inspectors noted that CM-AA-CLC-301 is the administrative procedure for engineering

calculations including calculations for fire protection systems.

Corrective Actions: The licensee declared the low-pressure carbon dioxide system in the Unit

1 and 2 cable vaults non-functional, entered the associated TRM action statement, and

performed a preliminary recalculation to justify functionality. The licensee initiated a corrective

action assignment to finalize the calculation.

Corrective Action References: CR1236252, CA12063265, and CA12082541

Performance Assessment:

Performance Deficiency: The inspectors found that the licensees failure to implement the fire

protection program in accordance with licensee procedure CM-AA-CLC-301, which resulted

in non-conservative calculation, was a performance deficiency within the licensees ability to

foresee and prevent.

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 calculation deficiency resulted in negative margin

for amount of carbon dioxide needed to suppress a fire in the cable vaults, which resulted in a

reasonable doubt of functionality in the as-found condition of low-pressure carbon dioxide

system. This issue is similar to more than minor example 3.h. in IMC 0612, Appendix E, in

that, the licensee revised the calculation to solely obtain favorable results.

Significance: The inspectors assessed the significance of the finding using IMC 0609

Appendix FProperty "Inspection Manual Chapter" (as page type) with input value "NRC Inspection Manual 0609</br></br>Appendix F" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process., Fire Protection and Post - Fire Safe Shutdown SDP. In accordance with IMC 0609, Appendix F, Attachment 2, Degradation Rating Guidance, the inspectors assigned a

low degradation rating due to the revised preliminary calculation resulting in concentration

above the required amount. Specifically, the revised preliminary calculation resulted in

approximately 76 pounds of carbon dioxide above the required amount. In accordance with

IMC 0609, Appendix F, Attachment 1, Significance Determination Process Worksheet, Step

1.3 - Low Degradation Deficiencies, the finding screened to very low safety significance

(Green). In addition, the inspectors verified that the non-conservative calculation for the fixed

suppression system did not adversely affect the ability of the system to protect any equipment

important to safe shutdown.

Cross-Cutting Aspect: Not Present Performance. No cross-cutting aspect was assigned to

this finding because the inspectors determined the finding did not reflect present licensee

performance.

Enforcement:

Violation: License Condition 3.I, Fire Protection, states in part, The licensee shall

implement and maintain in effect the provisions of the approved fire protection program as

described in the Updated Final Safety Analysis Report UFSAR Section 9.10.1, Design

Bases, states in part, Compliance with these criteria is contained in the following

documents Fire Protection Program documents and the associated Administrative

Procedures describe the administrative and technical controls. CM-AA-CLC-301,

Engineering Calculations, Attachment 1, Fundamental Expectations, stated, in part, that

assumptions shall be justified and bounded by the station design basis. The design bases

layout which included the void space is detailed in Drawing 11448-FC-24D, Plan and Details,

Elevation 15 feet - 0 inches, Auxiliary Building.

Contrary to the above, from at least 2008 to August 24, 2023, the licensee failed to implement

and maintain in effect, the provisions of the approved fire protection program as described in

the UFSAR, resulting in a calculation that did not justify functionality of the low-pressure

carbon dioxide for Unit 1 and Unit 2 cable vaults. Specifically, the licensee did not ensure that

design inputs regarding the layout of the cable vaults were incorporated into the calculation.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with

Section 2.3.2 of the Enforcement Policy.

Licensee-Identified Non-Cited Violation

71111.05

This violation of very low safety significance was identified by the licensee and has been

entered into the licensee corrective action program and is being treated as a non-cited

violation, consistent with Section 2.3.2 of the Enforcement Policy.

Violation: License Condition 3.I, Fire Protection, states in part, The licensee shall

implement and maintain in effect the provisions of the approved fire protection program as

described in the Updated Final Safety Analysis Report UFSAR Section 9.10.1, Design

Bases, states in part, Compliance with these criteria is contained in the following

documents Fire Protection Program documents and the associated Administrative

Procedures describe the administrative and technical controls. Licensee procedure CM-AA-

FPA-100, Fire Protection/Appendix R (Fire Safe Shutdown) Program, states, in part,

Penetration seals must provide equal or greater fire rating than that of the fire barrier.

Contrary to the above, on August 24, 2023, the licensee identified a degraded fire penetration

on the fire barrier wall between the Unit 1 safeguards building basement and the Unit 1 cable

vault that did not provide the required three hour or greater fire rating. The licensee repaired

the degraded penetration, which had existed for an unknown period prior to identification.

Significance/Severity: Green. The inspectors assessed the significance of the finding using

IMC 0609 Appendix F, Fire Protection and Post - Fire Safe Shutdown SDP. The finding was

determined to be of very low safety significance (Green) because there is an adequate

automatic suppression system on either side of the fire confinement element in accordance

with IMC 0609, Appendix F, Attachment 1, Step 1.4.4: Fire Confinement, Question 1.4.4-B.
