( 1.0 Introduction 1,1 overviev !
l This binder contains the results of American Electric Power Service l Corporation's (AEPSC) review of the Cook Nuclear Plant's centrifugal !
fire pump system for its compliance with the National Fire 'j Protection Association (NFPA) Codes. This code compliance review i specifically deals with the four high demand fire pumps, as well as '
the low demand fire pump. These pumps have been evaluated against i NFPA 20 " Centrifugal Fire Pumps". !
1 1.2 Backr.round j 1
In developing our Fire Protection Commitment Data Base. it was found I that AEPSC=had committed to NFPA 20. AEPSC engineers were assigned I to review, evaluate and justify code compliance issues t'or this. l code. The results of their reviews are contained in this report. ;
1.3 Scope of Work i This analysis evaluates the centrifugal fire pumps installed at the Donald C. Cook Nuclear Plant to the requirements of NFPA 20. The 1969 edition of NFPA 20 van the edition under which the system was ,
originally installed and therefore, this is the edition year upon i which the system has been evaluated. 3 The fire pumps-are to be evaluated against the code requirements to ;
determine complianco, noncompliance and open items. Deviations are i to be reevaluated to determine whether each item could be deemed '
acceptable "as installed" based upon credited plant procedures or past practices at the plant. Deviations and open items which cannot be justified on' these bases or on changes to the' specific coda i reqt irements in later editions,1are then to be evaluated based on-- -
engineering judgements, calculations, analysis of plant design +
features, field reviews etc. In instances where the deviation ;
cannot be justified, modification = are to be made to the systems. .
All justifications, evaluations and recommended modification: are described in the Code Compliance Verification Checklist portion of this report.
The areas of the. plant that have been reviewed include:
. Units 1 and 2 Diesel Fire Pump Rooms in the Screenhouse (Fire
-Zone (FZ) 28 and 30).
Units 1 and 2 Turbine-Building Pump Bays (FZ 2). '

( - Two chapters of NFPA 20 are not applicable to the Donald C. Cook- -
'" / Nuclear Plant. These chapters are as fo11own:
-i
. Chapter 300 "Special Fire Service Pumps". I 1
- Chapter 800 " Steam Turbine Drive".
Noither of these chanters apply since these types cf fire pumps and i drivers are not utilized at the Cooh Nuclear Plent. '
L Future modifications to the fire pump systems are to be evaluated ,
for NFPA 20 code compliance. Any noted deviations and/or i justifications will be documented and contained within this report. !

1.5 ceneral Assumptions This report utilized the following general assumptions shown below:
.(1) Specifications and drawings were used-to evaluate the piping, i fittings and miscellaneous hardware used in the fire pamp ,
-systems to confirm compliance with the requirements of NFPA 20 in effect'at the time of installation
-(2) Workmanship and construction practices during installation of l the pumps complied with the code requirements in effect at the time.
(3) It is assumed that all surveillance tests and procedures arc i properly implemented.
2.0 Purpose The purpose of.NFPA 20 is "to provide a reasonable degree of protection i
._for life-and' property from fire thr; ugh installation requirements for centrifugal fire pumps based upon sound engineering principles, test dats and field experience. Guidelines a'.i established for the design, installation and maintenanceEof these pumps, pump drivers and associated equipment. .The standard. endeavors to continue the excellent _ record that has been established by centrifugal pump installations and to meet the needs-of changing technology, Nothing in this standard is intended to restrict new technologies or alternate arrangements providing the level of safety prescribed by the standard is not lowered."

With this statement in mind, it should be understood that it is
, recogaized that the fire pumps installed at Donald C. Cook Nucicar Plant do not meet this standard verbatim. It is also recognized that the fire pump systern is not below the level of safety prescribed per NFPA 20. The plant's fire pump system reliability is derived through redundancy and independence. The following systern description should help the reader understand the level of protection at the Donald C, Cook Nuclear Plant.
Two 2,000 gpin at 152 psi horizontal centrifugal electric motor drivt3 fire pumps, two 2,000 gpm at 152 psi dieuel driven, vertical turbine fire pumps and a 500 gpm at 152 psi horizontal centrifugal electric rootor driven fire pump are provided for the fire water system. These fire pumps discharge into underground ring headers around the outside of the plant and into the interior ring header in the Turbine Building. This arrangement forms a series of smaller interior exterior loops connected through isolating valves to assure flow from multiple directions.
The fire pumps are started automatically and sequentially so that the systern can be supplied immediately with adequate quantities of water at the required pressure. The fire pro *.ecticn water flow may vary from as low as 30 gpra for a single sprinkler in operation to as much as 4,700 gpra for the combined flow, including hose streams, for the Unit 1 main transformer and Turbine Building wall exposure systems. One can see that store than enough pumps exist to supply even the largest water demand system. In fact, it can be argued that two of the 2,000 gpm fire pumps (n)
V can marginally supply enough water for a fire on the largest demand system, llenc e , it is evident that a great deal of redundancy was installed within the plant's fire pump arrangement.
The high demand electric fire pump motors are controlled from 600 V, electrically operated, draw out circuit breakers which are installed in metal clad switchgear enclosures qualified for Class I nuclear service.
Each of the electric fire pump circuit breakers is powered from independent busses, and each bus can be energized from separate emergency diesel generators. The pumps and controllers are completely isolated from each other, the pump being located in a separate pump room and the controller (circuit breaker) located in a separate switchgear room. This is consistent with the control of nuclear safety related pwnps installed at Donald C. Cook Nuclear Plant. Operation of the pumps is monitored and can be manually controlled form a centralized, continually manned control room. This is consistent with the basic philosophy of operating a nuclear generating unit. Control power for the breakers is supplied from a nuclear Class IE battery system. It is felt that the high demand electric fire pump controllers, being of the same type and quality as those for safety related equipment, are adequate to meet fire protection requirernents . They have proven to be reliable.
The redundancy of fire pumps and the complete independence of operation of one fire pump to another (including power sources) provides overall system reliability far greater than can be achieved by a single pump installation meeting the specific requirements of NFPA 20.

I i-E 3.0 Methodology NFPA 20 was broken down into two distinct categories (electrical and mechanical). The Piping, Valves, HVAC and Fire Protection Section of the !
Nuclear Engineering Department was tasked with evaluating all of the mechanical chapters contained within this code (chapters 1, 100, 200, 600 and 900). The Instrumentation and Control Section of the Nuclear j Engineering Department was tasked with evaluating all electrical chapters contained within this code (chapters 400, 500 and 700).
NFPA 20 was reviewed in depth to determine which sections specifically I addressed the ability of the plant's fire pumps. Code Sections covering topics, such as; information only, references to other NFPA codes, construction or equipment arrangement and nonrelevant types of occupancies were not included in this evaluation as these subjects do not affect the ability of these fire pumps.
4 The mechanical portion of this review was performed by both a field ;
walkdown (see NFPA 20 Walkdown Checklist portion of this binder) and a l document search. A summary of their results is contained in the ;
Mechanical Section f. the NFPA 20 Compliance Evaluation portion of ,
this binder. One can see that each paragraph of the code was ;
evaluated for complianco/non compliance, i The electrical portion of this review was performed by a document search
-as well as a field walkdown conducted by cognizant Electrical /I6C >
Engineering personnel. A' summary of their results is contained in the Electrical Section of the NFPA 20 Compliance Evaluation portion of this j binder. Once again, one can see that each paragraph of the code was evaluated for compliance / noncompliance.
This evaluation lists the applicable code sections; whether the fire pumps did/did not comply or if the code sections are not applicable to the fire pumps; and comments or justifications for. each noncomplying /not n applicable section. This evaluation also has an additional column te '
identify the documents-reviewed for verification of the specific code-sections. One can see that each paragraph of the code was evaluated for compliance / noncompliance.
In addition to the above mentioned portions of this bindes. there'also exists a " correspondence" section (attachment 1), as well as a section i that contains a copy of the 1969 edition of NFPA 20 (attachment 2).
4.0I' Conclusions / Recommendations .
This evaluation et .cluded that the Donald C. Cook Nuclear Plant's fire pump installation is generally-in compliance with NFPA 20. The fire pump -j systems were evaluated against the code requirements of the 1969 edition t to determine compliance, noncompliance and open items. Deviations were reevaluated to determine whether each item could be deemed acceptable NFPA 20 '

Fire Protection System Fire Pumps rio. P.J. Russell 9 to J.C. Jeffrey The purpose of this memo is to inform you of a significant change to RFC-12-3005, "Dedic:.ed Firn Protection Water Supply," concerning the licensing process. NS&L has determined that it is necessary to maintain the existing diesel fire pumps as well as the new fire pumps being installed under the new water supply system. This mandate is a result of their concern that the NRC will eventually require the Cook Nuclear Plant to design thu fire protection system to handle a simultaneous
,-, seiomic and fire event.
(\--) This change will require us to maintain the existing fire pumpn in accordance with all our existing commitments. As you know, one commitment is to be in f ull compliance with NFPA 20, " Centrifugal Fire Pumps." llence, all of the concerns which were being addressed in RFC-12-3020 (which was cancelled) have to be reopened. We are requesting that you initiate a new RFC to address these concerns. This RFC is necessary in order to take full credit for the existing diocol fire pumps.

" STANDARD FOR THE INSTALIATION OF CENTRIFUGAL, FIRE PUMPS" jCOPE:
This analysis evaluates the centrifugal fire pumps installed at the Donald C.
Cook Nuclear Plant to the requirements of NFPA 20. The 1969 edition of NFPA 20 was the edition under which the pumps were installed ar.d evaluated.
PURPOSE:
The purpose of NFPA 20 is "to provide a reasonable degree of protection for life and property from fire through installation requirements for centrifugal fire punps based upon sound engineering principler, test data and field experience. Guidelines are established for the (esign, installation and raintenance of these pumps, pump drivers and associated equipment. The standard ende<vors to continue the excellent record that has been established by centrifugal pump installations and to meet the needs of changing technology. Nothing in this standard is inteuded to restrict new technologies er alternate arrangements providing the leve'. of safety prescribed,by the standard is-not lowered."
k With this statement in mind, it should be understood that it is recognized o
that the fire puiaps installed at Donald C. Cook Nuclear Plant do not meet this standard verbatim. It is also recognized that the fire pump system is not below the level of safety prescribed per NFPA 20. The plant's fire pump system reliability is derived through redundancy and independency. The following system description should help the reader understand the level of protection at the Donald C. Cook Nuclear Plant.
Two 2,000 gpm at 152 psi horizontal centrifugal electric motor driven fire pumps, two 2,000 gpm at 152 psi diesel driven, vertical turbine fire pumps and a 500 gpm at 152 pai horizontal c.entrifugal electric motor driven fire pump are provided for the fire water system. These fire pumps discharge into underground ring headers around the outside of the plant and into the interior ring header in the Turbine Building. This arrangement forms a series of smaller interin -exterior loops connected through isolating valves to assure flow from multiple directions.
The fire pumps are started automatically and sequentially so that the system can be supplied imrnediately with adequate quantities of water at the required pressure. The fire protection water flow may vary frota as low as 30 gpm for a
-single sprinkler in operation to as much as 4,700 6pm for the combined flow, including hose streams, for the Unit 1 main transformer and Turbine Building wall exposure systems. One can see that more than enough pumpa exist to supply even the largest water demand system. In fact, it can be argued that two of the 2,000 gpm fire pumps can marginally supply enough vater for a fire
.(i on the largest demand system.' Hence, it is evident that a great deal of redundancy was installed within the plant's fire pump arrangement,
/* 11 ttGss tadt / l S2ye 2 of E The high demand electric fire pump motors are controlled from 600 V,

A number of these deficiencies impacted documents prepared by the PIR.F Section. Our response to thc ABB Irtpell comments are as follows.
NFPA 20 - FIRE PUMP CODE COMPLIANCE REPORT Item C.1 r Sections 41a and 41b. The compliance statement indicated that the ftre Q] pumps are isolated in separate fire zor:es. Although this may be true for the two diesel driven fire pumps, the three electric driven fire pumps are all located within the same fire zone (Fire Zone 2), Further clarification should be provided to address the concern of the installation of these pumps within the same fire zone.
Response
Our response to Sections 41a and 41b have been revised for clarification.
Item C.2 Section 143b. The compliance statement has indicated that the unlined steel suction pipes installed tor the fire pumps has not experienced excessive friction lors. The basis for this statement should be indicated (i.e., flow testing). Also, the statement that the internal painting of the suction piping is an " unnecessary expense should not be provided as a part of any justification. This statement should be deleted.
Response
Ovr response to Section 143b has been revised to delete the " unnecessary expense" corment. We also added the Performance testing procedures as technical reference for the basis of our statement that excessive
{qj friction loss through the suction pipe is not a problem.

Section 222a. This section has been listed as not applying; however, this section is an extension of Sections 222b and 222c and should be addressed accordingly.
Response
Our response to Section 222a has been revised so that there will be no misunderstanding in our complete compliance with Section 222 of NFPA 20, The following is the Pl%s Section's response to ABB Impell's comments concerning AEPSC's memos dated February 8,1989 and April 26, 1969. _
Item A ,
P A hydraulic analysis should be performed to verify the adequacy of the existing water supply system to support the demands of the existing and any nov suppression systems installed.
Responae
- A computerized program has been purchased for the purpose of evaluating-existin3 as well as new fire suppression systems, This program is being; installed onto the AEPSC computer system by calculation number DCC-FP-12 MC05 S. I r
Item B.1 ,
i These memos further discuss justifications made for deficiencies t identified in Impell's Report No. 09 0120 0123. The evaluations ,
j ; provided in these memos should identify the technical data used in l
- supporting the conclusions made (i.e., AEPSC memo dated June 17, 1988).
Response-These memos are based on the engineering judgement of a qualified fire protection engineer. The justifications were written upon the completion'of a field walkdown conducted by the author.

Code Compliance Verification Checklist for NFPA 20-1969 ' Standard for the Insta!!ation of Centrifical Fire Pumps".
ABB impell's review of the Cooe Compliance Verification Checklist for NFPA 20 identified several generic deficiencies which are detailed below.
/'3 A. Numerous code sections and justification statements have not provided a
() technical reference to provide a basis for the conclusion made in the compliance statement. The code sections noted, but not limited to, include Sections 243 through 531 and 666c through 934. The technical references are essential for supporting the respective compliance statement or justification.
B. Numerous " Comply" or 'Does not Apply" statements made to document compliance to code section requirements, did not indicate the basis for why the system is in compliance. These code sections include Sections 443,454a, 456c, 456d, 511e, 512c, 513di, 513d2, 514b2 thru 514b9, 514c1, 514c2, 515d4, 515e, 525 thru 528, 712a thru 712c, 713e2 thru 713g, 714a2, 714a3, 714b1, 714b3,715b1 thru 715c2,715d4,714e3 thru 715f3. The applicable supporting statements should be provided to document why compliance or non-applicability is true.
C. Inconsistencies were noted in a number of statements raised questions which requires additional clarifications. These sections include the following:
- 1. Sections 41a and 41b. The compliance statement indicated that the fire pumps are isolated in separate fire zones. Although this may be true for the two diesel driven fire pumps, the three electric driven fire pumps are all located within the same fire zone (Fire Zone 2). Further clarification should be provided to address the concern of the installation of these pumps within the same fire zone.

- 2. Section 1438. The compliance statement has indicated that the unlined steel suction pipes installed for the fire pumps has not experienced excessive friction loss. The basis for this statement should be indicated (i.e., floty testing). Also, the statement that the internal painting of the suction piping is an " unnecessary expense" should not be provided as a part of any justif; cation. This statement should be deleted.
J. Section 222a. This section has been listed as not applying, however, this ection is an extension of the Sections 222b and 222c and should be addressed accordingly.
- 4. Section 440. This section may not apply since this facility is a power plant and does not have a transformer specifically provided for the fire pumps.
(Qsd
- 5. Section 451c, The compliance statement made for this section implies that there is a non-compliance with the system however, a detailed justification has not been provided. This justification should be provided.
- 6. Sections 455b and 455d. The compliance statements for these sections seem to be incomplete since the statements only make reference to either the high or low demand fire pumps. Further clarification should be provided to indicate that all electric driven pumps have been reviewed against the requirements of these sections.
- 7. Section 513d3. The compliance statement does not adequately address the code section requirements. The compliance statement should address whether the pump controller components (i.e., power supplies, fuser, have beef. rated for continuous duty. This system should be evaluated agaif.st this code sect'on's requirements, t
- 8. Section 514a. The last sentence in the justification statement provided has not been completed. This statement should be completed.

ABB impell's review of numerous evaluations performed by AEPSC to show compliance with deficiencies identified in Impell's Report 09-01204123, indicated the following open items.
A. A hydraulio analysis should be performed to verify the adequacy of the existing water supply system to support the demands of the existing and any new suppression system installed.
B. The review of AEPSC's memos dated 2/8/89 (NFPA 13) and 4/26/89 (NFPA 72E) indicated the following open items.
- 1. These memos further discuss justifications made for deficiencies identified in ABB Impell's Report 09-0120-0123. The evaluations provided in these memos should identify the technical data used in supporting the conclusions made (i.e., AEPSC memos dated 6/17/88).

From J.D.-Markham / f To P.J. Russell This memorandum is to document an analysis of the availability of the fire pumps due to a control room fire.
This document is at the request of E.A. Taylor as noted in the attached letter. ,
We had previously indicated in our NFPA 20 Code Compliance Review that the four (4) main (high demand) fire water pumps (two (2) electrical driven and two (2) diesel driven) are completely independent. 'The fire pumps are independent -
physically and electrically (power and control). However, O there are some interconnections of fire pump control circuitry between Unit 1 and Unit 2 control rooms that signal a back-up fire pump to start in the event fire water ,
pressure is inadequate. The question arises whether these interconnections would affect an adequate supply of fire water-due to a control room fire.
These interconnections are electrically separated but cannot be claimed to be separated according:to Appendix-R criteria.
Hosever,- the probability of a' fire affecting any two fire pumps.is unrealistically remote. A detailed examination of the circuitry indicates the only Appendix R separation-concern would be the 24VDC starting control circuits of the two diesel fire pumps. The circuits of the two pumps are located within the same control panel in both Unit 1 and Unit 2 control rooms. A high current short to ground on bnth start circuits could prevent the diesel fire pumps from starting (including local start), but an open. circuit or a short between control conductors would not prevent local starting.
There are no interconnections of the main (high demand) electric driven fire pumps control circuits fros Unit 1 to Unit 2 control rooms. Also, in our opinion, a control' room fire'that would prevent either of-the main (high demand) electric driven fire pumps from being started (local f
manual or automatic) cannot be postulated since the start L

-.In; summary-iniour opinion, a control roomLfirst (1) would in the most likely. worst case situation prevent the starting of one-diesel-driven pump, (2) could, although highly improbable,-prevent the starting of both diesel driven pumpe, (3)-would not prevent the starting of either electric driven pumps.

Region III recently was at the plant doing a fire protection inspection audit on open Fire Protection items. One of the items thac they reviewed and subcequently closed +sas the open item on the Fire Pump controllers and their diffennees from NFPA '.0. The study that you performed on these controllers was given to Jeff Holmes, Re61on III, for further review. During a follow-up exit prone call last week, (fr.
Holmes inform- ,us that he was cloring out the item on the Fire Pump controllors.

Ronald N. Gardner, Chief -/l-d7 Plant Systems Section Date Inspectica Summary Inspection on February 13-17, March 15, and April 5,1989 (Reports No. 50-315/89004(DRS); 50-316/89004(DRS))
Areas Inspected: Routine, unannounced inspection to review the implementation of the licensee's fire protection program including a followup of licensee action on previous inspection findings; review el the fire protection organization; administrative controls; fire protection system surveillance test
- program; Quality Assurance; battery room exhaust fans; and Licensee Event Reports (LER) (30703, 64704, 90712, 92700, a:1d 92701).
Results: Of the seven areas inspected, three violations were identified (f ailure to properly seal C02 system valve in the open position-Paragraph 5; failure to provide adequate design control measures-Paragraph 8; and improper electrical cable routing discovered by corporate reviewers not communicated 9 actions-Paragraph 8). Additionally, two other violations were also identified;to
i
~ ,
v! engineering evaluation be presented in an auditable form and that the
' evaluation be expanded to include fire damper manufacturers other than Ruskin.
In response to the inspector's request, the licensee developed an internal memo dated February 23, 1989, from H. Young to J. Grier, which indicated that an evaluation will be performed to confirm that all Ruskin dampers not previously tested were bounded by the testing previously performed and that the scope of the evaluation will be expanded to include dampers other than Ruskin. Thic, evaluation will consider fire dampers in Appendix R and Appendix A fire walls and a report of this evaluation is scheduled to be completed by January 15, 1990.
Based on the licensee's proposed actions, this Part 21 (316/84006-PP) is considered closed. The proposed licensee actions are considered an open item (315/89004-01(DRS); 316/89004-01(DRS)) pending review and acceptance of the damper test results.
- c. (Closed) Open Item (315/85013-01(DRS); 316/85013-01(0RS)):
Unprotected structural steel beams support 4 inch poured concrete above each of the diesel fire pump rooms. The rooms were provided with sprinkler protection and the diesel fuel oil tanks were installed in a sand covered pit. Subsequent to the previous inspection, NRR
( indicated that adequate fire protection features ware in place.
( ])
During this inspection, the inspector toured the area. Due to the presence of the sprinkler system, the storage of the fuel oil tank in a sand pit, and the availability of fire hoses and foam, it appears that a potential fire can be easily controlled and extinguished.
Based on this information, this open item is considered closed.
- d. (Cleted) Open Item (315/85013-03(DRS); 316/85013-03(0RS)): The licensee utilized tygon plastic tubing as a flexible connector in the reactor coolant piping oil collection system. This item was to remain open pending the licensee's submittal of documentation clarifying the use of tygon plastic tubing in the oil collection system for review by NRR.
During this inspection, the inspector obtained the licensee's documentation regarding the use of tygon plastic tubing and forwarded the documentation to NRR. The results of this review will be documented in a future safety evaluation report.
'e. (Closed) Open Item (315/85013-11(DRS); 316/85013-11(DRS)): The licensee was unable to provide the applicable generic test data for penetration fire seals at the time of the inspection, Inspector review of the NRC issuea Safety Evaluation Report dated July 31, 1979, identified that the licensee had cited applicable generic test data for the penetration fire stops. This data indicated that the 9
5
7 I) silicone foam material in this (the tested) application provided a
\ three hour fire resistance to an ASTM E-119 type fire exposure. The SER also specified that during a site visit many of the Unit 3 penetration fire stops were observed. In addition, the SER specified that an additional penetration fire stop test was performed for a Unit 2 penetration seal design. As a result, the SER concluded that the penetration fire stops which were in place provided sufficient protection from the unbounded spread of fire along electrical cables.
Based on the SER review and a visual inspection of safety-related areas during plant tours on February 13, 14 and 15, 1939, to confirm that selected required penetrations were sealed, this item is considered closed,
- f. (Closed) Open item (315/85013-04(ORS); 316/85013-04(DRS)): The two electric motor-driven high demand fire pumps should be prcvided with controllers that are specifically tested and approved for fire service use. The controllers should comply with all applicable provisions of NFPA.
The NRC safety evaluation transmitted by letter dated July 31, 1979, to the licensee, indicated that the licensee's position regarding the controller's ability to meet the applicable provisions of NFPA 20 was reviewed and determined to be acceptable. Based on this review, this item is considered closed.

Several Licensee Event Reports were submitted to the NRC regarding fire barriers that were degraded without the licensee establishing compensatory measures as required by Technical Specification (TS) 3.7.10. The failure to have establisned the required fite watch patrols in accordance with the Action Statement of TS 3.7.10 is considered a violation (315/89004-02(DRS); 316/89004-02() ,5)).
The degraded fire barriers were subsequently repaired. During this inspection, the inspector was informed that improved personnel training has contributed to the prevention of recurrence of this problem for approximately the last two years. This violation meets the tests of 10 CFR 2, Appendix C, Section V.G; consequently, no Notice of Violation will be issued, and this matter is considered closed.
- 3. Fire Protection Organization
,The inspector examined the qualifications of a corporate fire protection engineer, the plant fire protection coordinator, and other personnel who perform fire watch duties.
During this review, the licensee provided the inspector with resumes of the corporate fire protection engineer and the plant fire protection coordinator. The corporate fire protection engineer has degrees in fire O

- 21. REQUIREMENTS. Fire pumps should be provided with as large and reliable a supply of water as possible. The ade- r-quacy and the dependability of the source of water are of l primary importance and must be fully determined at the ,"
time of installation, also the prospects for its reliability in the future. The minimum water level with maximum dis. ;.
charge from the pump must be determined. Where a store.!
supply is the only one available, a reliable method of re. *f plenishing the supply should be provided. Representative-
~
of the pump manufacturer shall assist in estab!ishing thm ;

)' 210. General, 211. SUITABILITY. The deep well turbine-type pump is f particularly suitable for hre purnp service when the source mf r
of water is located below the surface of the ground and it !T. i would be difficult to install any other type of pump below y C,
the minimum water level. It is a vertica shaft centrifugal 4
pump with rotating impellers suspended from the pump P;.
head by a column or eduction pipe which also serves as a i
support for the shaft and bearings. It was originally de- f i
signed for installation in bored wells, but may also be used h.
to lif t water from lakes, sinnms, open sumps, and other o.
sub surface sources. Oil. lubricated enclosed line shaft or %
water. lubricated open line shaft pumps will be acceptable. j 1 '
212. MAXIMUM Drrrit. Wells should not be considered j
' as a source of supply for fire pump service where the water -
level when aumping at 150 per cent capacity exceeds 200 3, j feet from t1e surface of the ground. In all applications ?,
where the water level is expected to exceed 50 feet the au- " -
thority having jurisdiction shall be supplied with data on ", j the draw-down characteristics of the well and the pump performance to determine the available discharge pressure .,
at the discharge flange of the vertical pump. J' 0713 B-4 h 4

I Chapter 300-Special Fire Service Pumps. iI J '
j .310. General. M' i 311. APPLic/. Tion. Special fire service pumps are in. M, tended for installation in situations where the available '
supply of water is limited and draft of water in ex.
D.;' ; !
cess of the maximum delivery of the pump would be likely *; .
to reduce the supply pressure to an undue extent. It is not
! usually advisable to reduce the pressure in public mains l 4 i l below 20 pounds per square inch suction pressure while the M j pump is operating at its rated capacity. Special fire service (;'
pumps may also be used as booster pumps in situations +
l where there is no deficiency in the volume of water a tailable t !
but the pressure is inadequate to supply the quan'.ity of Q~
water necessary for efficient discharge from the highes* c sprinklers. The authority having jurisdiction may permit T the use of these pumps for other special situations where ;' i such use is acceptable to said authority. They are for use '
only where the conditions are not such as to justify in.
stallat, ion of a standard fire pump. ;
312. Ust. Special fire service pumps may be installed :l i
instead of standard fire pumps only when their installation is approved by the authority having jurisdiction.
320. Water Supplice.

i 331. STANDARD PUMPS. Standard special fire servie" pumps have nominal capacities of 200, 300 and 4T>0 gallons n per minute with preasure ratings between 40 and 100 psi.
The pumps shall have such wrformance characteristics that !.
the power required of the c riving motor will not exceed 30
- horsepower at any rate of water delivery within the delivery '
range shown by the head. delivery curve of the pump. w
?" !
332. SELECTION or PUMP. Selection of a pump for a given condition should be based on the capacity and pres- :>
q' sure conditions in the supply mains as determined by test.
and the capacity and pressure requirements of the installa. $Q i

32d Pressure Maintenance Pumps (Jockey or Make-Up }
Pump). The 'use of an auto:natic pressure ;
maintenanco pump is desirable under some cir-cumstances.to maintain a uniform or a relatively high pressure on the fire protection system. The 3 3 J' 7 ~1 capacity and pressure rating of the pump shall be
- suf ficient to maintain the desired pressure against the leakage in the system as approved by the autherity having jurisdiction. -A centrifugal type pump is preferable. L'hcre the discharge-pressure at pump shutoff of a centrifugal type pump exceeds the working pressure rating of the }
fire protection equipment, or a turbine vane l (peripheral).or a positive displacecent type of {
pump is used, a suitable relief valve shall } {
be installed on the pump discharge to prevent { j damage to the fire system. (See Figures 100a t j

142a A horizontal pump with driver is correctly aligned on bedplate before shipment. This alignment, how- T f)f F ever, usually is disturbed during transit or by in- Nh J L correct leveling of bedplate on foundation. The pump manufacturer's instructions on alignment should be carefully followed.
142b Any baseplate, no matter how heavily it is built may be slightly sprung in shipment, or may be dis- ,/ ,j/, . I torted by an unever; support. on the foundation, or ,,lii 'd' l 7

by uneven tightening of the : foundation bolts, or by the pull from the pipe connections. It is i necessary to be careful when installing the pump ,
