, REQUEST FOR ADDITIONAL INFORMATION SECTION 9.5.1 FIRE PROTECTION l WESTINGHOUSE ADVANCED PRESSURIZED WATER REACTOR DESIGN RESAR - SP/90 OCTOBER 1986

, TASK COMPLETION NO. 141213 i O ,

280.1 Section 9.5.1.1.d, pages 9.5-3. -4 The staff position reflecting fire protection for redundant safe shutdown trains in advanced reactor designs is that such O

redundant trains will be completely separated by 3-hour fire rated barriers, or completely separated by a 1-hour fire rated barrier with fire detection and automatic fire suppression throughout the area containing 1-hour fire rated barrier r separation. This protection is acceptable for redundant safe shutdown e:;Lipment located inside or outside primary contain-ment. The staff does not recognize as acceptable for use in Advanced Reactor Design any methods which rely upon:

o Spatial separation,  !

o Use only of automstic detection and suppression, or i

o Separation by radiant energy shields

, This is consistent with the guidance given in Section C.5 - I General Plant Guidelines. Subsection a. Building Desion, of Standard Review Plan, MREG-0800, Branch Technical Position CHEB o.5-1.

Section 9.5.1.1.d of the SSAR is inconsistent with this position. Provide clarification showing how RESAR SP/90 meets this position or provide justification for not doing so. ,

RESPONSE: -  !

Subsection 9.5.1.1(d) has been modified to clarify our intent to meet the guidelines provided in BTP CMEB 9.5-1. Note that contrary to what is stated above, the use of spatial separation isconsideredacceptableperparagraphC.5.b(2)(b).

L O WAPWR-AS 280-1 AMENDMENT 2 7388e:1d APRIL, 1988

280.2 Section 9.5.1.1.e, page 9.5-4 The staff understands that one of the major goals of the APWR is to streamline the review process by eliminating requests for deviation and the subsequent need for staff review of such requests. The last sentence on page 9.5-4 reads, "The design basis fire approach will also be utilized as appropriate to 2

determine if specific deviations (emphasis added) from the fire protection features approach will provide an equivalent level of V fire safety." This sentence is not consistent with the above stated goal. Please clarify this issue. (NOTE: It is the staff position that PRA cannot provide the basis for exemptions torequirements).

RESPONSE

Subsection 9.5.1.1(e) has been moGified to remove the reference to "specific deviations"; deviations to the general separation philosophy are described in Subsection 9.5.1.3(a).

280.3 Section 9.5.1.3.a. page 9.5-7 The same concerns raised in Question 280.1 above apply here respecting spatial separation and use of one-hour fire rated barriers and fire detection and automatic fire suppression. In O. addition, we are confused by the wording in the second paragraph concerning the term "fire barriers." The commonly accepted definition of a fire area is a volume in a building that is bounded by barriers of some known fire resistance rating given

. in terms of hours. Please clarify the last sentence which reads, in part, "Similarly, fire barriers will be provided within a fire area to separate. . . ."

RESPONSE

i Revisions to Subsection 9.5.1.1(d) and 9.5.1.3(a) are provided

, to provide conformance with the requirements, and to clarify the

! definition of a fire area.

,' The concerns raised in question 280.1 above reflecting spatial

,' separation, and the concerns raised in question 280.3 above reflecting use of fire barriers within a fire area apply in Subsection a. Separation of Safe Shutdown Equipment. Please clarify this section.

RESPONSE

Subsection 9.5.1.3(b) has been revised to provide clarification.

280.5 Section 9.5.1.4.1, page 9.5-8 Please explain how the flame and heat resistant characteristics 3 of the passive fire protection features will be determined, and to what they will be compared.

RESPONSE

It is expected that the flame and heat characteristics of the passive fire protection features included in the SP-90 plant can be demonstrated using existing test data. If not, additional tests will be performed during the Final Design Stage.

280.6 Section 9.5.1.4.1.a, page 9.5-9 Should the reference in the second line be to Subsection 9.5.1.3(a) rather than to 9.5.1.4(a) as shown? ,

RESPONSE

Yes! The text has been revised to reflect Subsection 9.5.1.3(a) as the correct reference section.

280.7 Section 9.5.1.4.1.b and e, page 9.5-11 o See Question 280.1 above for comments on radiant energy O- shields, o We have two questions concerning the last sentence in i 9.5.1.4.1.b which reads, "Each fire barrier component will be tested or analyzed to assure adequate fire resistance ratings." ,

i '

a. We assume that "component" refers to such things as doors, dampers, penetration seals and cable wraps (we have already stated that radiant energy shields are not acceptable), and that such "components" will be tested in configurations like those to be used in this O advanced reactor design. The staff finds this concept acceptable. If "component" refers to individual structural portions of total barriers (i.e. columns and beams or portions of concrete slabs used in the construction of fire wall or ceiling-floor assemblies),

then this concept is not acceptable. Clarify what is l

meant by "component."

.1

b. The staff generally does not accept analysis in lieu of full scale testing for determining the adequacy of barrier fire resistance rating. How will such analysis be accomplished to assure that the results will be ,

acceptable in place of actual full scale testing? '

. This position is consistent with Section C.S.a of BTP CHEB 9.5-1 of the Standard Review Plan, NUREG-0800, j RESPONSE:

l l

With regard to part a. of the question, the staff's assumption l with regard to the definition of ' component' is correct.

In response to part b., it is the intent to utilize, where l practical, proven components and materials (see also response to i

Question 280.5). In scoe :ases, additional analysis may be i required to determine the adequacy of barrier fire resistance ratirq. If such analysis cannot be executed in an acceptable

manner, additional testing will be performed during the Final Design stage.

o What are the qualifications and responsibilities cf the person who will review and evaluate each configuration? '

o What code or standard does "analyzed" refer to?

,O o Will the criteria used in these analyses be that in ASTM

V E-152 and NFPA 80 or will other criteria be used?

RESPONSE

a. The paragraph in question was in error and has been deleted,
b. Page 9.5-12 has been revised for clarification purposes.  ;

280.9 Section 9.5.1.4.2.b, pages 9.5-13, -14

. Will each fire pump be equipped for automatic and remote manual start, and manual stop only at the fire pump location (no remote stop capability), or automatic stop capability that conforms to the requirements of National Fire Protection Association i Standard No. 20 "Standard for the Installation of Centrifugal l Fire Pumps?" Also, NFPA 20 is not referenced along with other <

NFPA standards at the end of this section. Is this an oversight, or does Westinghouse not intend to follow this standard with respect to their fire pump installations?

]

RESPONSE

Exclusion of NFPA 20 here was an error of omission (this standard is referenced throughoutSubsection9.5.1). The SP/90 will conform to this standard with respect to fire pump

! installations.

9.5 OTHER AUXILIARY SYSTERS  !

e 9.5.1 Fire Protection System 9.5.1.1 Design Basis I The Fire Protection Program is developed to assure, through a defense-in-depth .

satrix, that fire will not affect redundant components required to achieve safe shutdown and to prevent an increased risk of radioactive releases to the  !

environment. In addition, the Fire Protection Program is intended to minimize O property damage and protect personnel from injury due to fire. The l defense-in-depth protection matrix is based on recognition of potential fire

hazards in safety-related areas and the need to protect redundant safe l shutdown et;uipment from a comen mode fire-related failure.

l

) a. A Fire Hazards Analysis will be conducted to assess vulnerability of l plant safety-related equipment to damage by fire. The study will j include an inventory of in situ flammable / combustible material and a .

t

' review of anticipated plant activities such as storage areas, radwaste

  • l step-off pads, oil quantities in various pieces of equipment, and oil  ;

transport and handling methods to determine locations in which a  !

serious fire may occur. i i

! Based on this information, the following features of plant general arrangement will be reviewed: l l

o Access and egress routes o Equipment locations

o Construction materials.

.\

This review will assess potential for damage to safety-related equipment and the effect of postulated fires relative to maintaining h

the ability to perform safe shutdown functions and minimize radioactive releases to the environmer.t.

b. Active and passive fire protection features will be provided in

- cor.bination as a means for assuring defense-in-depth against fire.

In order to preclude a single fire resulting in an unacceptable release of radioactivity, passive fire protection features with apprcpriate fire resistance qualification will be provided to separate redundant systems and equipment required to achieve safe shutdown.

In areas where plant processes or presence of combustible material result in potential for fire ignition and significant fire propagation er personal injury, apprcpriate fixed fire suppression and detection systems will be installed to promptly notify plant personnel and provide fire suppression capabilities, g Additional fire barriers, fire detection equipment, fire hose stations, and portable fire suppression equipment will be provided based on results of the Fire Hazards Analysis and professional judgment of an engineer experienced in fire protection.

c. Fire protection concepts for the WAPWR consider fire concurrent with less of off-site power such that safe shutdown is achievable following less of systems, equipment, and comronents in any one fire area without use of off-site power. Fire, is considered concurrently with g

other Design Basis Events or Accidents only when one may initiate the other. Examples are as follows:

o Fire induced by a Design Basis Accident (such as earthquake),

o Loss of Coolant Accident (LOCA) induced by fire.

WAPWR-AS 9.5-2 AMENDP.ENT 2 5405e:1d APRIL, 1968

i Where the possibility exists for fire to be induced by a Design Basis  ;

Accident, the hazard will be mitigated by system equipment design l (such es a seismically qualified oil collection system for reactor  !

coolantpumps). Where a loss of equipment function or malfunction due to fire may result in a LOCA, vulnerable equipment and components will be protected from the effects of a fire to preclude a LOCA.

]O i

If a fire is not initiated by or does not initiate another Design Basis Event or Accident, a fire is not considered to occur concurrent with and coincidental to Design Basis Events such as:

O o Design Basis Earthquake 1 o Ternado o Flood j o LOCA

) d. In Nuclear Power Block (NFB) areas outside containment separation of safety r31ated equipment will be achieved by three hour fire barriers.

1 i

> Ins'ide containment, separation by three hour fire barriers is not practical because all compartments need to be in communication with l each other in order to relieve pressure following a high energy line break. For this reeson, fire protection is achieved by one or more of l the following parameters:

i 2

o Separation by existing structural walls (note that these may be 3 l

hour fire barriers, but they do not fully enclose the equipment requiring separation),

i 1

O o Separation by horizontal distance of more than 20 feet with no intervening combustibles or fire hazards, coupled with fire il detection and automatic fire suppression.

10 Fire barriers will also be utilized to separate safety related areas from non-safety related areas as dictated by the Fire Hazards

i nPWR A5 9.5-3 AMENDMENT 2 i 905e:1d APRIL, 1953 i

l

Analysis. Similarly, fire barriers will be provided within a fire area to separate components which present a fire hazard to other .

2 components or cable concentrations within the area. For example, each diesel generator is separated from the remainder of its associated g

safety related area.

e. In order to determine appropriate combination of activo and passive fire protection features for property conservation and perser.nel safety considerations, the design basis fire approach will be used, employing professional judgment of engineers experienced in fire protection and use of validated analytical techniques existing in the public domain or developed specifically for the APWR.

2

f. Fire protection fluid systems will be arranged by piping netwerk and provision of sectional isolation valves, such that a single failure or system impairment will not remove primary and secondary protection from service (i.e., fixed and manual suppression systems).
g. The citimate objective of the WAPWR Fire Protection Program is to minimize uncontrolled release of radioactive material to meet requirements of 10CFR100, 9.5.1.2 Codes and Standards
a. Nuclear Regulatory Commission NUREG-0800, Standard Review Plan Section 9.5.1 of the Standard Revie.

9.5.1.3 Protection of Safe Shutdown Related Equipment g

a. Separation of Safe Shutdown Equipment Safety related redundant components which may be required to function 2

to achieve safe shutdown will be protected as described in Subsection 9.5.1.1(d), with the exception of the Main Steam and Feedwater Tunnel WAPWR-AS 9.5-6 AMENDMENT 2 5405e:1d APRIL, 1988

and the Main Control Room outsido containment, and the pressurizer relief system inside containment.

V The Main Steam & Feedwater Tunnel contains the safety class portions of the main steam and feedwater lines outside containment in a single f- area. The probability of fire initiation in this area is low because of the low density of cabling in this area. In addition, the steam generator power operated relief valves, which may be required to achieve cold shutdown and which are located in the Main Steam and feedwater Tunnel are backed up by the relief valves of the Steam

/ Generator Overfill Protection System, which are located inside containment.

With regard to the Main Control Room, the probability of fire initiation is low because of the following features:

o The extensive use of multiplexed interconnection, which has eliminated the need for cable spreading rooms. 2 o 'The use of l w voltage (24V) within the control boards.

l o The use of firs > retardant materials i

Moreover, fire detection and mitigation are enhanced by the continuous presence of plant operators in the Main Control Room by the incorporation of automatically actuated fire extinguishing systems, and by the availability of portable fire extinguishers.

Nevertheless, because a fire in the Main Control Room cannot be excluded, two emergency panel rooms are provided for in the SP-90 design. Each of these two emergency panel rooms is located in one of I the redundant safety related areas and includes the capability to j bring the reactor to cold shuf.down using one of the redundant trains of engineered safety features.

O WAPWR-AS 9.5-7 AMENDMENT 2 5405e:1d APRIL, 1988

The pressurizer power operated relief valves (PORV's) are a safety grac'e means to depressurize the Reactor Coolant System (RCS) to allow injection of borated water by the High Head Safety Injection Pumps.

The redundant pressurizer PORV's, which are safety grade, are located in a single area above the pressurizer. This exception is judged acceptable for the following reasons:

o The probability of a fire in this area is extremely remote due to 2 the absence of significant quantities of combustible material o The charging pumps would normally be available to inject borated water into the RCS without the need for depressurization o RCS depressurization is achievable without reliance on pressurizer PORV's (i.e. using the safety grade hot leg letdown valves),

although this would be a less desirable mode of operation due to the complex operator action required.

b. Protection of Safe Shutdown Power and Control Cables Redundant safe shutdown cables and associated circuits will be O

protected as described in 9.5.1.1(d), except as noted in 9.5.1.3.(a) 2 above.

c. Fire Barrier Rating Barriers will be rated in accordance with criteria as stated in Subsection 9.5.1.1(d).

9.5.1.4 Fire Protection System and Feature Descriptiens O

9.5.1.4.1 Passive Fire Protection Features Passive fire protection features are considered to be building assemblies and l insulating materials which have fine and heat resistant characteristics.

l WAPWR-AS 9.5-8 AMENDMENT 2 5405e:1d APRIL, 1988

Passive fire protection features consist of fire rated structural assemblies,

. (i.e., walls,floorsorceilings),whichhave penetrations protected by fire

% rated devices (i.e., dampers, doors or firestops). Insulating materials consist of cable wraps and heat resistant coatings. The fire rating of these structural assemblies, penetration protection devices and insulating materials is determined by appropriate test procedures.

Passive fire protection features, henceforth referred to as fire barriers, are used to separate safety related systems from nonsafety related areas, redundant safety-related divisions or trains from each other and safety-s related components which may present a fire hazard from other safety-related components. This separation will ensure that a single fire cannot cause loss of ability to achieve safe shutdown.

a. Location of Fire Barriers Fire barriers will be provided on each elevation of safety-related areas to meet the criteria stated in Subsection 9.5.1.3(a). The 2 following is an elevation-by-elevation list of redundant safety-rel'ated equipment which will be separated from its counterpart by three-hour fire rated barriers.
