Notice of Violation and Proposed 2 Imposition of Civil Penalty during the OA 1994 audit: however. as of August 22. 1996. no date had been proposed for the completion of any required modi fications.

c. Inadequate procedures for the evaluation and control of transient combustibles was identified during the 1994 OA audit: however, as of August 22, 1996, the applicable procedures had been revised but had not been effectively implemented. The issue associated with the storage of combustible materials was scheduled to be resolved by November 1996.
d. Inadecuate design control of fire barrier penetration seals was icentified during the 1994 QA audit. As of August 22, 1996, this issue had not been fully resolved and was scheduled for completion in late 1997.
e. Changes made to the plant without following the design change process (i.e., inadequate controls over plant modifications which affect the fire protection program) were identified during the 1995 QA audit. As of August 22. 1996, this issue was scheduled to be resolved by 1997.
f. Lack of testing of the backup fire suppression system for the cable spreading room since 1982 was identified by the 1995 OA audit. As corrective action. TVA planned to install a blind flange in this system and remove it from service:

however, as of August 22, 1996, the design change package was scheduled to be issued September 15, 1996 but no schedule date was provided for completion of this modification.

2. From initial plant licensing until September 21, 1993. 326 fire barrier penetrations in Units 1 and 2 which provided fire rated separation between redundant safety related components were not functional as required by TS 3.7.12. Fire Barrier Penetrations.

Specifically, on Se)tember 21. 1993. TVA determined that a number of fire dampers in Jnits 1 and 2 were not installed in accordance with the vendor's recommendations and were not functional. The required compensatory measures, which included an hourly fire watch, were implemented for these areas on September 21. 1993. and continue: however, as of August 22, 1996, final resolution of this issue was not scheduled until 1997.

3. TVA's 1994 QA audit identified problems with the control of combustible and transient fire loads in the Elevation 669 Spare Room, yet two specific violations of transient fire load procedural requirements, contained in Procedure SSP-12.15.

2 ISSUES TO BE DISCUSSED I 1 '. Technical Specification, Section 6.8.1.f, states that written procedures j shall be established, implemented and maintained covering the Fire i Protection Program implementation.

t i TVA's Nuclear Quality Assurance Plan (NAQP), TVA-NOA-PL89-A j provides a complete description of the quality assurance program for ,

! operation of the Sequoyah Nuclear Plant. NAQP TVA-NQA-PL89-A, i Section 5.0 identifies the programs'and features for which the NAQP applies. Section 5.0.B.6 lists fire protection as one of these programs.

I NAQP, TVA-NOA-PL89-A, Section 10.2.2.B, Corrective Action for l

Adverse Conditions, states: TVA nuclear. organizations and onsite non-l TVA nuclear. service organizations performing quality-related activities at nuclear facilities shall promptly identify and resolve adverse l.

conditions.

l The licensee failed to promptly identify and/or resolve adverse I conditions related to the fire protection program in that:

! (1) Quality Assurance audits of the fire protection program, i specifically, QA audits of October 9,1992, August 1,1994, l January 24,1995, and July 14,1995, identified fire protection .

discrepancies associated with inadequate implementation of the

!- Sequoyah fire protection program and as of August 22,1996, l corrective action had not been implemented to adequately address these discrepancies as follows:

l

).

a. Inadequate emergency lighting installation and an l

inadequate preventive maintenance program for the installed

! lighting units identified by the 1992 audit. At the end of l this inspection, field testing and preventive maintenance

procedure revisions to resolve this issue were in progress.

j b. No restoration program for approximately 1500 degraded i fire barrier penetration seals identified during the 1994 audit. At the conclusion of this inspection, engineering

[ design data input was scheduled for early 1997. As of F August 22,1996, no date had been proposed for i

l l

l .

i f

completion of required modifications.

j c. Inadequate procedures for the evaluation and control of transient combustibles identified during the 1994 audit. At

the conclusion of this inspection, procedures had been i revised but had not been effectively implemented. The issue associated with the storage of combustibles materials
in the plant were proposed to be resolved by November i 1996.

4

d. Inadequate design control over. fire barrier penetration seals 1 identified during the 1994 audit. Resolution of this issue is

[ scheduled for late 1997.

! e. Changes being made to plant without following design change process, i.e.' inadequate controls over plant changes j which affect the fire protection program, were identified during the 1995 audit. This issue was scheduled to be resolved by 1997. i

f. No testing of the backup cable spreading room fire suppression system for the cable spreading room since 1982 was identified by the 1995 audit. TVA planed to install a blind flange in this system and remove it from service. The design change package was scheduled to be issued September 15,1996. No schedule date was provided for completion of this plant change.

(2) From initial plant licensing until September 21,1993,326 fire barrier penetrations in Units 1 and 2 which provided tire rated separation between redundant safety related components were not functional as required by Technical Specification 3.7.12, Fire Barrier Penetrations. Specifically, on September 21,1993,TVA determined that a number of fire dampers in Units 1 and 2 were not installed in accordance with the vendor's recommendations and were not functional. The required compensatory measures which included a hourly fire watch were implemented for these areas on September 21,1993. Final resolution is not scheduled until 1998.

i 1

(3) Although previous TVA audits had identified problems with the l control of combustible and transient fire loads in the plant in the  !

elevation 669 spare room, continued violations of transient fire  ;

load procedural requirement were identified by the NRC inspector  !

on July 8-12,1996,in that: 1

a. Transient Fire Load (TFL) Permit TFL-95-0254 was issued for the storage of 1100 pounds of clothing and 400 pounds l of rubber / plastic radiation protective clothing on elevation i 690 between column lines A4 and A6 in the Auxiliary Building. This TFL permit expired December 31,.1995 and a new permit had not been issued and an appropriate engineering analysis had not been performed. This material

{

was stored directly beneath electrical raceways containing-safe shutdown related cables.

b. The following permits were issued for a spare room on elevation 669, were issued for longer than 6 months, did not receive approval by the Site Fire Protection Engineer, or had not received an engineering analysis to justify the change in occupancy: Permit TFL-95-0033 (high fire load),

issued February 5,1995 and extended.to December 31, 1996; Permits TLC-96-0003 (no fire load indicated) issued January 1,1996 with expiration date of December 31, 1996; Permit TFL-96-004 (medium fire load), issued January 1,1996 with expiration date of December 31,1996; and  !

Permit TFL-96-0005 (no fire load indicated) issued January 1,1996 with expiration date of December 31,1996.

2. Technical Specification 3.7.3, carbon dioxide (CO2) Systems, states that the Computer Room low pressure CO2 system shall be operable whenever equipment protected by the CO2 system is required to be OPERABLE.

From May 1990 until December 18,1995, the computer room low pressure CO2 system was inoperable. In May 1990, the heating ventilation air conditioning (HVAC) system for the Control Building had been modified by the installation of duct penetrations which were not arranged with dampers to close and isolate the room upon actuation of the CO2 system. The Computer Room CO2 system was placed out of

i r .

l service in December 1995 and remains out of service with a hourly fire j watch patrol implemented to meet the compensatory requirements of l~ the TS.

j 3. Technical Specification 4.7.12.a, Fire Barrier Penetrations, Surveillance

Requirements, states that each of the required fire barrier penetrations-

! shall be verified to be functional at least once per 18 months.

.The licensee failed to verify Auxiliary Building fire barrier penetrations in high radiation areas were functional at least once per 18 months. The Auxiliary Building penetrations in high radiation areas were not included in the 18 month surveillances performed in August 1995'and March 1994..

l

4. Technical Specification 6.8.1.f states that written procedures shall be established, implemented and maintained covering fire protection  !

program implementation.

i Technical Specification 4.7.11.4.c.2 states that each of the fire hose i

stations shown in Table 3.7-5 shall be demonstrated operable at least '

once per 3 years by conducting a hose hydrostatic test at a pressure of 150 psig or at least 50 psig above maximum fire main operating pressure, whichever is greater. The hose stations installed in the Reactor Buildings are listed in Table 3.7-5.

Between November 10,1990 and February 15,1996, TVA's surveillance procedures 1/2-SI-FPU-026-191.R, Fire Hose Inspections, for the reactor building fire hose stations were inadequate in that these procedures did not assure that the_ fire hose for these locations had been hydrostatically tested as required by TS Section 4.7.11.4.c.2 resulting in several fire hose stations being provided with fire hose that had not been hydrostatically tested within the required time.

NOTE:- -The apparent violations discussed in this predecisional enforcement conference are subject to further review and are subject to change prior to any resulting enforcement decision.

, Sequoyah Nuclear Plant Introduction TVA understands the significance of the fire protection issues and corrective actions and agrees that fire protection violations did occur SQN's recent history started with a four-phase Fire Protection improvement Plan in 1991 (61 of 63 items complete)

Several fire protection equipment upgrade projects are ongoing Desijite SQN's progress in the fire protection area, QA and NRC have noted some continuing deficiencies in program implementation SQN management now understands that delays in responsiveness were due to inadequate management involvement in fire protection (i.e., lack of ownership)

Corrective actions were taken that involved both organizational and personnel changes before NRC expressed current concerns  ;

SQN management relies on Quality Assurance to be intrusive Senior management will closely monitor the Fire Protection Program SQN is committed to timely completion of all tire protection issues 3 i i

- l Sequoyah Nuclear Plant Fire Protection History

- By 1988, programmatic Appendix R issues at SQN had been resolved

- In 1991, SQN developed a four-phase Fire Protection Improvement Plan (FPIP)

- Purpose of the plan was primarily to address Engineering items such as:

Evaluating the hydraulic performance of the Fire Protection System Updating the Fire llazard Analysis Completion of the Fire Protection Report Upgrading the Fire Protection System 61 of 63 items complete

- Several organizations were responsible for different aspects of fire protection l activities

- Original schedule was to complete this improvement plan by 1994

- After the FPIP began, both units at SQN were shut down in order to repair large amounts of piping on the balance of plant due to erosion / corrosion concerns i

- Resoitrees were temporarily re-prioritized to other design activities associated with the restart of the units

- Management determined that safety was not compromised by this decision ihe evaluation of the hydraulic performance of the Ilire Protection System was completed. Testing and analysis indicated that all tecimical specification requirements ,

were met

- The results also concluded there was more margin in the system than SQN previously believed  ;

- $RC was provided updates on schedule changes

- Independent of the FPIP, deficiencies were discovered during both site and corporate QA audits (1992 - 1995) -

Deficiencies spread over several organizations QA did not appropriately pursue the collective significance of fire protection issues 6

Sequoyah Nuclear Plant Fire Protection History  ;

- In May 1996, a corporate QA audit in fire protection escalated the issue that some long-term issues and previous audit findings (1992-1995) have not been ,

effective or timely l

- SQN management combined this escalation with the results of prior NRC-insp'ections and LERs, and concluded it was due to inadequate prior management involvement

- In Jpne 1996, after top management involvement, an integrated schedule was developed to track SQ~N lire protection issues

- To help implement enhanced management involvement, the responsibility for the Fire Protection Program was centralized within the Operations area

, Technical Support to Operations

- : Fire Protection now responsible for own surveillance instructions

- : One layer of management removed t

Fire Protection History

- A new Fire Protection Manager was also assigned in order to improve the implementation of actions within the fire protection organization

- Management is reviewing the Fire Protection Program on a weekly basis

- TVA self-assessment of the Fire Protection Program was performed utilizing '

experienced fire protection personnel from corporate, BFN, WBN, and an independent consultant ,

- Self-assessment concluded the first steps have been taken to correct immediate ,

problems; continued management attention is required ,

6 Sequoyah Nuclear Plant Fire Protection Apparent Violations i

I Criterion XVI 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, requires, in part, that measures be established to assure that conditions adverse to quality such as failures,  !

deficiencies, and nonconformances are promptly identified and corrected.

i Example 1 - Transient Fire Load Program For two areas on Elevation 669 (spare room) and Elevation 690 (protective clothing  ;

storage area) of the auxiliary building, requirements for control of transient fire loads were not met. The failure to promptly identify and resolve adverse conditions, ,

specifically the storage of combustible materials within the plant, is identified as an example of an apparent violation.

e Sequoyah Nuclear Plant Fire Protection Apparent Violations Exampie 3 - LER 327/93027, Degraded Fire Dampers Technical specification (TS) 3.7.12 requires all fire barrier penetrations (including fire dampers) to be functional at all times in fire zone boundaries protecting safety-related aieas. Fire dampers were installed in the various walls to provide a fire-rated separation from redundant safety-related components. The fire dampers at SQN had been inspected by the licensee a number of times during construction and preopera'tional and surveillance testing activities. These inspections failed to identify that the dampers were not installed in accordance with vendor's requirements. The failure to promptly identify and resolve the adverse conditions associated with the '

lire dampers is identified as another example of the violation.

i LER 327/96002, Fire Protection Ilose Stations TS 4.7.11.4.c.2 requires, in part, that each of the fire hose stations shown in Table 3.7-5 (of the TSs) shall be demonstrated operable at least once per three years by conducting a hose hydrostatic test .

Between November 19,1990 and February 15,1996, TVA's surveillance  :

instructions for procedures 1/2-SI-FPlJ-026-191.R for the reactor building fire hose stations were inadequate in that these procedures did not assure that the fire hoses for these loc 9tions would be hydrostatically tested as required by TSs. This issue is identified as an apparent violation.

Regulatory Perspective TVA's review of the regulatory requirements concludes the following:

- SQN's Fire Protection Program meets all Appendix R, technical specifications, and other regulatory requirements

- Program implementation problems have occurred

- No actual and minimal potential safety significance

- A review of each issue indicates that multiple redundant systems, components, or administrative processes were available even with the noted degradation to mitigate the consequences as the result of a fire

- Aggregate effect has been considered Engineeringjudgment shows Defense-in-Depth Fire Protection Philosophy adequately mitigates the consequences of a fire 33

Regulatory Perspective

- Regulatory significance

- TVA understands the regulatory significance of these issues Appropriate corrective actions were taken for all issues Comprehensive corrective actions address root cause

- Consistent with the NRC Enforcement Policy and past NRC practice, the four.LERs should be closed to non-cited violations ~

- The transient fire load and QA audit finding issues should be l combined as two examples of a Severity Level IV, Criterion XVI  :

violation 1

SQN developed corrective actions before enforcement was initiated

- ' No regulatory purpose for escalated enforcement i
