TEST PROCEDURE
- CABLE VAULT ROOM ENCLOSURE INTEGRITY TEST l l
1.0 PURPOSE 1 l This procedure provides a method to equate Cable vault enclosure i 9terminedkage to worst by case Carbon Dioxide the tracer gas and leakage. door Enclosure leakage will be f an test procedure outlined bel The l calculation method provided by NFPA 12A, App. B, 1989 edition makes it possible to predict the level of the descending interface of the CO2/ air-mixture with respect to time. This calculated value provides a conservative prediction of the CO2 concentration and maximum hold time for the Cable Vault room. 2.0 DISCUSSION 2.1 Background The CO2 total flooding system was installed in the Cable vault to provide protection from a potential deep seated fire. The original installation was a manually activated system, which was installed in 1970. In j 1977 the system was upgraded to an automatically initiated system with second shot capability provided from the west switchgear room. The system was not discharge tested for design concentration as such a test was not required by NFPA 12, 1968 or 1973 edition. ; In 1977 a Tech Spec ammendment was issued which reflected the modifications to the Cable Vault CO2 system. The Safety Evaluation Report which was issued in support of this ammendment, refers to the design criteria for the system. At the time of installation the system was tested to the criteria of the National Fire Protection Association standard for CO2 systems (NFPA-12, 1977). The standard of record at that time did not require a full d Recently, the NRC, claiming the powers of the Authority Having (Jscharge test.isdiction, has interpreted that a full discharge test is required to prove L a adequacy of the CO2 system (ref. 3.9). In the response to the VY response to the notice of violation, the NRC stated that they would entertain an alternate to the full discharge test if a conclusive test method could be designed (ref. 3.10). The 1989 Edition of NFPA 12A, The Standard on Halon 1301 rire Extinguishing Systems includes an Enclosure Integrity Procedure in Appendix B. This test was developed for the subcommittee of the NFPA 12A committee which was charged with the task of developing an acceptable alternative to full discharge testing of Halon 1301 gaseous fire suppression systems. Appendix B is the result of the efforts of the subcommittee and the research team. This alternative test was presented to the NFPA 12A committee and approved. The test was then added to the draft of the new edition of the code. This draft j was then reviewed by the membership of the NFPA and approved by them for
- inclusion in the 1989 cdition of the code.
In cases where a substantial differential pressure exists across the bound 6ry of the enclosure additional test methods are required. In this case the differential pressure across the Ceble Vault - Reactor Building wall may be as auch as 1 1/2 inches of water. To ensure that this boundary of the enclosure it, leah tight, a tracer gas test will be conducted prior to the Enclosure Integrity test. The_ tracer gas test wil?. ensure the integrity of the cable Vault - Reactor Building wall thus guarenteeing the validity of the model usod in the Enclosure Integrity test analysis. I 1
To coot the recont NRC intorprototion of NFPA 12, and to test the adequacy and operability of the CO2 system, a tracer gas test and an Enclosure Integrity Test will be completed in the cable vault room. This will verify I t the Cabis Vault CO2 system is p ysically capable of providing and l ntaining a CO2 concentration of 5 % CO2 (by volume) for a period of ten : utes. In the event that these criteria are not achieved, further evaluation l will be performed with the potential for the performance of addit al Enclosure Integrity tests. 2.1.1 The Engineering Support Department is the organization with the overall responsibility for the test. 2.1.2 The vendor for these tests will be Retrotech Energy Innovations . Limited. 2.1.3 The vendor will provide the personnel for the completion of the tracer gas test and the Enclosure Integrity test. 2.1.4 The tracer gas and tracer gas analyzer equipment will be t provided by Vermont Yankee. 2.1.5 A calibrated door fan assembly will be provided by the vendor for the completion of this test. 2.1.6 In support of the test a Temporary Modification (89-53) may be installed to provide controlled ventilation of the Cable Vault room during a CO2 discharge. 2.1.7 The results of the Enclosure Integrity test will dictate the necessity for the installation of the Temporary Modification. 2.2 Safety Evaluation 2.2.1 Safety Class The cable vault automatic total flooding CO2 suppression system , (machanical equipment, piping, and electrical control equipment) is a non-safety class system. The CO2 system provides fire protection for safety class electrical cable and equipment, and is therefore designated a vital fire protection system. The walls which comprise the boundaries of the Cable Vault cro designated as vital Fire Barriers. These walls provide protection from fires which may occur outside of the Cable Vault. Additionally, the walls are designed to confine a fire which may occur within the Cable vault. The walls also serve the function of confining the CO2 which will be discharged in the ! event of a fire within the cable vault. 2.2.2 System / Test Discussion l The automatic total flooding high pressure CO2 fire suppression system , provides protection from a deep seated electrical fire for the Cable Vault. ' The system was installed in accordance with the requirements of the National Fire Protection Association (NFPA) fire code No. 12, 1969, 1973, and 1977 editions. The required concentration for this application is 50% CO2 by volume. The design flow rate is 840 lbs/ min of CO2 for 200 seconds. This will , provide a CO2 concentration of 30% within two minutes, and a 50% concentration l
/-Aghin seven minutes. The design " soak" time at 50% concentration is ten g jutes. The design calculations are documented in Reference 3.8.
i l
l Tho discharge of CO2 in the Cablo Vcult raises o potential lifo safoty consideration. Since CO2 is an asphyxiant, this test procedure addresses precautions that ensure that a 50.73(a)(2)(x) event (i.e. hampering site l l does not occur. The completion of this test procedure will not 9tsonnel)
/olve the actual discharge of CO2.
The initial portion of this test involves the introduction of a tracer gas to the Cable Vault atmosphere. The tracer gas to be utilized in this test is Sulfur Hexafluoride (Sr6). The tracer gas will be used in concentrations of 250 ppm or less. This level of Sr6 is well below the toxic limit of 1000 ppm. The Toxic Gas Monitoring System is not capable of detecting ST6, therefore the control Room Ventilation system and the Toxic Gas Monitoring system will be left in their normal operating configurations. The potential for overpressurization of the room due to the discharge of CO2 has been evaluated utilizing the guidance provided in NrPA No. 12; 1989. This possibility will be examined through a comparison of the Equivalent Leakage Area as determined by this test with the required free ' venting area as determined by the NrPA 12 code requirements. This ensures that sufficient vent area will be available to prevent excessive pressure buildup within the room during CO2 discharge. A review of the Switchgear room CO2 full discharge test results indicated that controlled venting of the room during the initial phase of the CO2 discharge was necessary. This provided a controlled means of evacuating air and allowing for a uniform concentration of CO2 throughout the room. This test will determine the need for the installation of such a controlled venting mechanism in the Cable Vault. Should these test results indicate the necessity for a controlled ventilation, Temporary Modification 89-53 will be installed. (The controlled psure ventilation of the exhaust fanwill andbe damper provided by delaying the for approximately deenergization three and minutes. This
\_ 4 prevent the pressurization of the Cable vault room and will enhance the distribution of CO2.
By controlling and minimizing the pressure within the room by delayed closure of the exhaust damper (TM 89-53), it is assured that wall, door, and fire barrier seal integrity will be maintained during the discharge test. The tracer gas and Enclosure Integrity test of the Cable vault will verify the design capabilities of the total flooding CO2 system. 2.3 This test does not present significant hazards not described or implicit in the safety analysis report, and there is reasonable assurance that the health and safety of the public will not be endangered in that: 2.3.1 The probability of occurrence of an accident is not increased in that the Enclosure Integrity test will only slightly increase the air pressure within the room. There will be no change in ambient temperature, nor any adverse impact on the operability of equipment or systems. The tracer gas test will be conducted at a concentration well below the toxic limits. To ensure that licensing commitments and fire protection standards are maintained, the continuous fire watch will be continued throughout the test. Although the automatic initiation of the O
CO2 systea will bo discblod, tho syston will still be availcble for manual activation. This will provide an equivalent or better level of fire protection for the Cable vault during the implementation of this test. and 2.3.2 The consequences of an accident is not increased in that the tracer gas test or the Enclosure Integrity test will in no way affect the operation of equipment powered or controlled by cables or components located in this area, and 2.3.3 The probability of equipment malfunction is not increased because the Enclosure Integrity test only serves to slightly increase the rooms air presure. hvIther the tracer gas test nor the Enclosure Integrity test alters the condition or configuration of any equipment within or outside of the Cable vault room, and 2.3.4 The consequences of equipment malfunction is not increased , because the introduction of SF6 or the pressurization of the room will have no detrimental effect on the operability of equipment within the Cable vault or Reactor Building, and 2.3.5 The possibility for an accident of a different type than O previously analysed is not created in that this test does not change or modify the intent of the design or equipment configurations. The CO2 system will remain available for manual
- activation.
and 2.3.6 The possibility of malfunction of a different type than previously analysed is not created because this test does not change the bases for any previous analyses. and 2.3.7 The m:* gin of safety as defined in the basis for any technical speci'. cation is not reduced because this test makes no changes to an-; safety limits or controls. 2.4 Based upon the above this test does not constitute an unreviewed safety question as defined in 10CFR50.59(a)(2).

Calculation of Peak Preosuro Durina Diocharao Problem Description The purpose of this calculation is to determine the maximum pressure which will be developed in the Cable Vault during a discharge of the CO2 system. NFPA 12, the Standard on Carbon Dioxide Extinguishing Systems, 1989 Edition, provides guidance in determining necessary leakage area for very tight enclosures. This method accounts for the discharge rate of the installed system as well as the structural strength of the enclosure.
On October 31, November 1, and November 2, 1989, data was gathered by Retrotec Energy Inovations Ltd. personnel to determine the Equivalent Leakage Area for the Cable Vault. This information, in conjunction with these calculations allowed for a prediction of the Equivalent Leakage Area as well as the maximum pressure anticipated during a CO2 discharge.
- 2) Method of Solution The maximum pressure was determined utilizing the approved methodology provided in NFPA 12, section 2-6.2, Pressure Relief Venting. This calculation assumes the expansion of the CO2 to be 9 cu ft/lb. .
From section 2-6.2.1 of Reference 3.1:
[ X = Q / (1.3) (P)
X = Free venting Area (in E)
Q = Calculated carbon dioxide flow rate (lbs/ min)
P = Allowable strength of the enclosure (psf)
=
From Table 2-6.2.3 of Reference 3.1:
Tvoe Construction Windace Pressure In. H2O PSI Bars-cace Light Building 100 MPH 25 psf .175 5 0.012 To determine the maximum pressure anticipated, the above calculation can rearranged to:
P = (Q/1.3 X)
Where:
X = ELA (in )
- 0.61 0.61 is the discharge coefficient for a hole in a flat plate.

- 3) Conclusions The above calculation provides a maximum pressure during the discharge-of CO2 in the Cable Vault. The value of 5 inches of water as specified by NFPA ;
12 is for light building construction. The enclosure which.makes up the Cable- '
Vault is of much heavier construction, with the exception of the doors. The values for light building construction account for the. construction of the doors. The value predicted by this calculation demonstrates that the room ,
.will remain intact during a discharge of the CO2 system in the Cable Vault.

ft APPENDIX A NOTICE OF VIOLATICN Vermont Yankee Nuclear Power Corp.' Docket No. 50-271 Vermont Yankee Nucitar Station License No. OPR-28 As a result of the inspection conducted on March 20-23, 1989, and in accordance i with the "Genertl Statement of Policy and Procedure for NRC Enforcement Actions", 10 CFR Pcrt 2, Appendix C (Enforcement Policy 1989) the folicwing violation was identifiec: i Technical Specification 3.13.0 r2' quires that the carbon dioxide fire suppression (CO2) systems located in the cable vault and diesel fire pumptrd day tank room shall be operable whenever equipment in the arta protected by the systems is required to be operable. Tha technical specifications $7 require a continuous fire watch if the CO2 system in the cable vault is inoperable and an hourly fire watch if the CO2 system in the fire pump day tank room is inoperable, h In a letter to NRC dated January 31, 1977, the licensee stated that the carben dioxido systems at Vermont Yantee were designed to meet the require- = jO ments of the 1977 National Fire Protection Association (NFPA) Standard 12. NFPA Standard 12 Section 1-7.3 specifies that the installed carbon dioxide systems shall be tested and the tests performed shall t,o adequate to deter- ! mine that the system has been properly installed and v-ill function as m intended. The CO2 systems are designed to achieve a 50 percent concentra-tion. In the cable vault, this concentration must be maintained for ten minutes. Contrary to the above, as of April 21, 1989, the CO2 systema in the cable vault and in the diesel fire pump dey tank room had not been demonstrated to be operable, in that no tests had been performeo of their capability to reach and maintain design concentrations of CO2, and the appropriate fire watches had nos been implemented. _- This is a Severity Level IV Violation (Supplement 1) Pursuant to 10 CFR 2.201, Vermont Yankee Nuc) ear Power Corp is hereby required a to tubmit to this office, within 30 days of the date of the letter transmitting 1 this Notice, a written statement or enplanation in reply, including: (1) The reasons for the violations; (2) the corrective steps which have been taken and the results achieved; (3) corrective steps which will be taken to avoid further violations; and (4) the date when full compliance will be achieved, blhere good cause is shown, consideration will be given to extending this # gqc4g' a response time, i , Ewa i d m 1 M , 10

2.0 Followup of Previous Inspection Findinos (Closed) Violation (89-04-01) Lack of Emeroency Lichts in the Control Room Torus Catwalk anc Fire Area FA-RB-5 The NRC identified the violation of 10 CFR 50 Appendix R, Section I!!.J in that emergency lights were not installed in the above areas. The licensee installed emergency lighting units in the' Control Room prior to the NRC team leaving the site. For the Catwalk area the licensee requested an exemotion from the requirement because the area contains lighting units powered from the Emergency Diesels. The NRC granted that y exemption. Fire Area RB-5 was re-examined by the licensee by turning off all lights in the area to determine the illumination. levels provided by the existing emergency lighting. The illuminttien was found to be adequate. The above actions satisfy the NRC concerns and this item is closed. (0 pen) Unresolved _ Item (68-04-02) Fire Stops in Reactor Bu11dina The NRC identified the concern that the fire stops installed to provide fire break zones were inadequately installed. These stops were installed in 5 to 7 foot strips on both sides of each fire break Area. The correct way of installing the fire stops would be to install the fire retardant thru the entire length of the fire break. The licensee committed to have the fire stops installed at the first opportunity. The licensee stated that they were unable to complete the engineering work associated with the fire stops, therefore, the fire stops will not be installed during this

The licensee, meanwhile, has in place, roving fire (Closed) Unresolved Item (88-04-03) Circuit Coordination Ouring the circuit coordination review of the Appendix R program, the NRC team observed that coordination curves and analyses for the 120V AC and 125V DC circuits were not available. The licensee acknowledged the coordi-nation and cocumentation concerns and committed to finalize the analyses. The analyses were completed and the inspector verified the time-current characteristic curves for the 120VAC and 120VOC circuits.The breakers This valve is used for containmentare adequately coercimated except for the breaker isolation in series with valve V10-18. One of these valves would remain closed because power cables for V10-17 and V10-18 are routec through different fire areas, therefore, a single fire could not disable both valves. The inspector had no further questions. This item is closed. (Closed) Unresolved Item (88-04-04) High Impedance Fault The NRC team identified that the analysis of the effect of high impecance O- faults on all electrical power sources required for safe shutdown was incomplete. The licensee completed this analysis and the inspector reviewed it with regard to fault conditions, assumptions for analysis, breaker 480V ACset points and safe shutdown operability for 120V AC, 125V DC and circuits. anelysis has been completed.The documentation concerning high impedance fault Based on this review, the inspector concluded that there is no high impedance fault concern and the safe shutdown load power supplies are adequately protected. = (Closed) Unresolved Item (88-04-05) Inadeouate Fuse Protection The NRC inspection team conducted a review of the common enclosure associated circuit concern to determine the adequacy of the electrical isolation protection. The team observed that 12 AWG conductors were protected with 35 Amp fuses instead of the required 30 Amp fuses. The inspectors reviewed the licensee analysis of the above concern. The 12 AWG conductors identified are cross-linked polyethylene insulated cables rated at 90'C continuous full load operation. . this type of cable is 40 Anp at 130*C up to 100 hours, which is stillThe emergency ; o above the rating of the protective fuses.

3.0 Controls of Combustibles and Icnition Sources The licensee has in place procedures that control the introduction of combustibles and flammables in safety-related areas. The licensee also has procedures that control the use of ignition sources such as frcm welding, cutting or grinding operations. The plant inspection by the inspector did not identify any unacceptable conditions.
- 4.0 Eautoment Maintenance Inspection and Tests The inspector reviewed several surveillance and testing procedures to determine whether the licensee has developed an adequate surveillance and maintenance program that assures-the functionality / operability of the ~
fire protection equipment. In addition, the inspector reviewed test records to verify compliance with applicable Technical Specification (TS) requirements. A violation was identified as follows: The inspector reviewed the carbon dioxide (CO2) systems installed in the cable vault, switchgear and diesel fire pump day tank rooms to verify that each system is capable of performing its required function. This review involved a system walk-down and a review of the test and surveillance procedures established to assure system operability. The applicable licensing requirements also were reviewed. Licensino Recuirements The CO2 systems are required by License Condition 3.F which states that an automatic CO2 system be provided in the cable spreading room (also referred to as the cable vault), the switchgear room and the diesel fire pump day tank room. The CO2 systems listed above are required to be operable by Technical Specification 3.13.0. The licensee in a letter to NRC dated January 31, 1977 from J. French I to V. Stello committed to abide by the 1977 National Fire Protection l Association Standard No. 12 (NFPA 12). This letter specifically states that the CO2 system in use at Vermont Yankee was designed to meet the requirements of NFPA 12. NFPA 12 is the guide for the design and installation of CO2 systems. Section 1-7.3 of this standard specifies that the completed system shall be tested to determine that the system will function as intended. The NRC has-adopted the recommendations of NFPA 12. This is stipulated in Appendix A to Branch Tecnnical Position 9.5-1,
r . na The CO2 system design was reviewed by the NRC and was (itscussed in an NRC dated Safety13, January Evaluation 1978. (SE), supporting License Amendment a3, - The SE states that the design of the CO2 system is acceptable because it can provide 50% concentration in the cable vault and maintain this concentration for ten minutes. The CO2 concentration and duration of concentration mentioned above are required for the effective extinguishment of deep seated fires that could housing occur ifequipment. electrical a fire started in areas such as the cable vault Procedure and Records Review The inspector reviewed the procedures which ensure that if a fire occurs in the areas protected by CO2 the proper alarms would activate, the ventilation dampers would close and the system would cischarge. The licensee also has procedures verifying that the design quantity of CO2 is available at all times. The review of these procedures did not identify any unacceptable conditions. - The inspector reviewed the CO2 system acceptance test records to
~
verify that the system can deliver the 50% of CO2 concentration for 10 minutes. The licensee preser.ted to the inspector the test results of the full discharge test conducted in the switchgear room. The licensee could not locate the records for tests for the other areas. However, they committed to search for the test records for these areas. The inspector indicated to the licensee that if these tests were not performed, the' system operability must be verified by a test. Regarding the switchgear room test, the licensee indicated that this test identified a condition where the concentration was not maintained at 50% for the entire 10 minutes in some locations of the switchgear room (high in the ceiling). On the advise of their vendor they made system modifications to improve the mixing of the CO2 so that this problem could be eliminated. The modifications included an adjustment to the discharge valve timing to slow CO2 injection. . They also made provisions for the ventilation dampers to stay open for five minutes to address room over-pressurization concerns and improve mixing of the CO2 in the room. The NRC on April 21, 1989 informed the licensee via telephone'that since the CO2 test records for the cable vault and the diesel fire pump day tank rooms had not been found and since inadequate evidence exists to verify that the system would function as intended, the system must be assumed inoperable and the compensatory measures-specified in the Technical Specifications be placed in effect. As a result of that call the licensee committed ,to declare the systeth O 4 I

- I inoperable and establish fire watches in accordance with the ;
Technical Specifications. Since compensatory measures for an incier- ! able CO2 system were not in effect when this deficiency was identified l by the NRC, this was a violation of the Technical Specifications - (violation.89-04-01). l 5.0 Quality Assurance (CA) Audit Review i The inspector reviewed the QA audits of the Fire Protection Program. The ! audits were found to be thorough. Audit finding were adequately-resolved. No unacceptable conditions were identified. ! 6.0 Fire protection Engineerina and Modifications The inspector observed activities that affect the Fire Protection-and- - noted the following .
- 1. The fire annunciator panel is located in the Security Room (SAS) ;
4 within the control room. The security monitoring panel that was- ' recently installed was placed right up to the Fire Panel making panel surveillance and testing difficult.
- 2. The licensee did not complete the work of the fire stops mentioned in Section 2 of this report. The need for these fire stops was identified in February 1988. The licensee must now erect scaffolds v l and do the modification work in the Reactor Building when the plant '
is at power.
- 3. The NRC, during the Appendix R inspection, could not verify the adequacy of the communication system because using walkie-talkie radios ;
i in some plant areas could adversely effect the plant. Walkie-talkies - would be used for communications to shutdown the plant from outside . the Control Room if a fire forced Control Room evacuation. The licensee
- committed to determine plant conditions for which use of.the communi-
- cation system is acceptable. The licensee reviewed the communications i
system and determined that the system would not perform adequately in i certain areas. The licensee corrected the problem by installing an ; antenna to enhance the radio signal. The corrective actions are adequate. The above items are examples where the engineering group did not perform a thorough job in the Fire Protection Area. 7.0 Fire Brigade Trainina 7.1 Procedure Review The inspector reviewed the fire Brigade Tra'ining program to verify that this program includes:
- a. Requirements for announced and unannounced drills;
p a' . y l b. Requirement for fire brigade training and retraining at prescribed frequencies;
- c. Requirements for at least one drill per year to be performed on a "back shift" for each brigade;
- d. Requirements for maintenance of training records.
No unacceptable conditions were identified. 7.2 _ Rec _ords Review The inspector reviewed training records of fire brigade members for calendar years 1988 and 1989 to ascertain that they had attended the-recuired quarterly training and participated in a quarterly drill, and received the annual hands-on fire extinguishment practice._ The inspector noted that all fire fighters have received the required training. However, the inspector observed that the licensee's procedures allow prospective fire brigade men.bers to be on the fire brigade without the initial hands-on fire fighting practice.- The concern is that personnel without firefighting experience can be a member of the brigade. The licensee explained that.the initial " live" fire fighting-training usually takes place during the warm weather months. The inspector verified that the licensee makes every effort to quickly O. qualify new fire fighters. This effort even includes sending some of them to fire Academies as far.away as Texas, but the procedures still allow membership in fire brigade without that training. At the time of the inspection, every member of the brigade had this training. The licensee was told of the concern and they committed to review it. This in an unresolved item. (89-04-02).- The inspector also noted that the licensee's record-keeping in this-area can be improved. The E, U licensee's staff had a problem locating the required records but ultimately the records were found. 8.0 Facility Tour The inspector examined fire protection water systems, including fire pumps, fire water piping and distribution systems, post indicator valves, hydrants and contents of hose houses. The inspector toured accessible vital and nonvital plant areas and examined fire detection and alarm iystems, automatic and manual fixed suppression systems, interior hose stations, fire barrier penetration seals, and fire doors. The inspector observed general plant housekeeping conditions and randomly checked tags of portabl.e extinguishers for evidence of periodic inspections. No deterioration of equipment was noted. The inspection tags attached to extinguishers indicated that monthly inspections were performed. 1 O

ir O No unacceptable conditions were identified. However, the inspector observed the following conditions requiring resolution by the licensee: i Housekeepino/ Hazard Control The inspectu observed that the licensee installed large wooden structures outside but next to the Reactor Building. These structures although temporary have been there for more than a year. A fire in these structures could affect the plant. The structures have no smokin floor.g signs but the inspector observed cigarette butts on the , The inspector also observed the licensee's practice of storing Nf combustible trash next to the training building. The inspectors observed a large nile of wooden pallets and other combustible truh bg.M stc*ed near the building. The inspector expressed the concern that a cig6rette from passers-by could ignite these combustibles. Within the Control Room, the inspectors observed that spare breathing. air bottles were stored on the floor. The inspector noted that these bottles represent a missile hazard to people and equipment. i penetration Review The inspector while in the cable vault inspecting the integrity of the fire seals noted that in the Northwest corner of the room, a sound of air leakage could be heard. MD$ This sound was later determined to be air leaking from the Reactor Building to the Control Structure via an apparently degraded penetration seal. That determination was made by the licensee. A work request to repair the seal was issued while the inspectors were still on site. 9.0 Unresolved Items Unresolved items are matters for which more information is required in ' order to ascertain whether they are acceptable, violations, or deviations. An unresolved item is discussed in Section 7.0. 10.0 Exit Interview l The inspector met with licensee management representatives (see Section 23, 1989.1.0 for attendees) at the conclusion of the inspection on March inspection The inspector at that time. summarized the scope and findings of the The inspector also confirmed with the licensee that the report will not contain any proprietary information. The licensee agreed that the inspection report may be placed in the Public Document Room without prior licensee review for proprietary information. (10 CFR 2.790). , At no time during this inspection, was written material provided to the licensee by the inspector. O

Dear Sir:
Subject:
Response to Inspection Report 89-04, Notice of Violation During a routine safety inspection of Vermont fankee's fire protection program conducted on March 20-23, 1949, a violation of NRC requirements was identified. Our response to this violation is provided below. l VIOLATION Technical Specification 3.13.0 requires that the carbon dioxide fire suppression (CO2 ) systems located in the cable vault and diesel fire pump day tank room shall be operable whenever equip-ment in the area protected by the systems is required to be operable. The technical specifications require a continuous fire watch if the CO2 system in the cable vault is inoperable and an hourly fire watch if the CO2 system in the fire pump day tank room is inoperable. j In a letter to the NRC dated January 31, 1977, the licensee stated that the carbon dioxide systems at Vermont Yankee were designed to meet the requirements of the 1977 National Fire Protection Association (NFPA) Standard it. NFPA Standard 12 Section 1-7.3 specifies that the installed carbon dioxide systems shall be tested and the tests performed shall be adequate to determine that the system has been properly installed and will function as intended. The C03 systems are designed to achieve a
$0 percent concentration. In the cable vault, this concentration must be maintained for ten sinutes.
Contrary to the above, as of April 21, 1989, the C03 systems in the cable vault and in the diesel fire pump day tank room had not been demonstrated to be operable, in that no tests had been per-formed of their capability to reach &nd maintain design con-centrations of CO2 , and the appropriate fire watches had not been implemented. Dl This is a Severity Level IV Violation (Supplement 1) _ _.,__._--_.m._-._ - - - - - -
