1.0 Introduction ('" 1.1 Overviev This binder contains the results of American Electric Power Service Corporation's (AEPSC) review of the Cook Nuclear Plant's storage of flammable and combustible liquids for its comp 1b ace with the National Fire Protection Association (NFPA) Codes. This code coupliance review specifically deals with the combustible oil storage room, the flammable liquid storage room and the portable flammable liquid storage cabinets located within the plant. These rooms (Miscellaneous Oil Storage Room and Flammable Liquids Storage Room) and storage cabinets have been evaluated against NFPA 30
" Flammable and Combustible Liquids Code".
1.2 Background
In developing our File Protection Commitment Data Base, It was found that AEPSC had committed to NFPA 30. AEPSC engineers were assigned to review, evaluate and justify code compliance issues for this code. The results of their reviews are contained in this report. 1.3 Scope of k'ork This analysis evaluates the dedicated flammable and combustible liquid storage rooms as well as the portable storage cabinets installed at the Donald C. Cook Nuclear Plant to the requirements of NFPA 30. The 1987 edition of NFPA 30 was the edition under which the rooms and cabinets have been initially evaluated. The 1987 edition year was chosen so that the rooms and cabinets would be reviewed against the most current code requirements. The dedicated storage rooms are to be evaluated against the code requirements to determine compliance , noncompliance and open items. Deviations are to be reevaluated to determine whether each item could be deemed acceptable "as installedd 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 code requirements in later editions, are then to be evaluated based on engineering judgements, calculations, analysis of plant design features, field reviews, etc. In instances where the deviation cannot ae justified, modifications are to be made to the systems. All justifications, evaluations and recommended modifications are described in the code compliance verification checklist portion of this report. The areas of the plant that have been reviewed include:
- Unit 2 Turbine Building Miscellaneous 011 Storage Room (Fire Zone (FZ) 89).
NFPA 30 Rev. O Page 3 of 8
lO: L/- - Service and Office Building Flammable Liquid Storage Room (FZ (j 131).
- Portab1L flammable _ liquid storage cabinet locations in the Auxiliary _and Turbita Buildings.
The scepe of'this review is limited to these areas since they are the only areas where flammable. liquids are stored or where combustible liquids are dispensed. It_was determined that AEPSC's commitment in our 1977 Response to Appendix A to BTP APCSB 9.5-1, Section D.2.(d), dealt with flammable liquids only. Therefore, only the flamme.ble liquids room (FZ 131) and the flammable liquid storage cabinets need be_ included in the scope of this review. However, in the practice of good fire protection engineering, the Miscellaneous oil Storage room (FZ 89) has been included in this scope because of the dispensing operations which take place within this room. Two chapters of NFPA 30 are not applicable to the Donald C. Cook ! Nuclear Plant. These chapters are as follaws:
- Chapter 2 " Tank Storage".
-- Chapter 3 " Piping, Valves and Fittings".
-pI Chapter 2_does not apply since no permanent flammable liquid tanks exist within the security boundary. Likewise, Chapter 3 does not apply since no flammable liquid piping systems are installed within the Cook Juclear Plant's security boundary. Combustible oil storage ranks were not evaluated against this code since no commitments were made by AEPSC to install these systems within the NFPA 30 requirements. Future modifications to the flammable and combustible liquid storage rooms are to be evaluated for NFPA 30 code compliance. Any noted deviations and/or justifications will be documented and contained within this report. Future storage of flammable and combustible-liquids within the portable cabinets will. remain under the control of plant procedure PMI-2270. 1.4 Fire-Protection Systems Reviewed The fire protection systems which have been reviewed are identified
-below:
Fire Area Fire Zone Unit Description B 89 2- Miscellaneous Oil Storage Room Sprinklers B 131- 162 Flammable _ Liquid Storage Room Sprinklers Note: The review of the sprinkler systems in these areas was limited to only the sprinklers and piping network within the identified rooms. 7 NFPA 30 Rev. O Page 4 of 8
l.5 Ceneral Assumption ( This report utilized the fellowing general assumption shown below: (1) Specifications and drawings were used to evaluate the piping, fittings and miscellaneous hardware used in the storage rooms to confirm compliance with the requirements of the appropriated NFPA codes in effect at the time of this review. (2) Workmanship and construction practices during of installation the systems complied with the code requirements in effect at the time. (3) It is assumed that all surveillance tests and procedurem are properly implemented. 2.0 Purpose The purpose of NFPA 30 is "to reduce the hazard (flammable and combustible liquid storage) to a degree consistent with reasonable blic safety, without undue interference with public convenience and necx tity which require the use of flammable and combustible liquids. Thus, compliance with this standard does not eliminate all hazards in the use of flammable and combustible liquids". With this statement in mind, it should be understood that it is recognized that the flammable and combustible liquids storage rooms as well as the portable storage cabinets installed at Donald C. Cook Nuclear Plant do
. not meet this standard verbatim. It is also recognized that these areas are not below the level ot safety prescribed per NFPA 30, as demonstrated by this report. The fire protection " defense-in depth" (as described within this text) philosophy assures plant safety.
3.0 Methodology NFPA 30 was broken down into two distinct categories (storage rooms and storage cabinets). The Piping, Valves, HVAC and Fire Protection Section of the Nuclear Engineering Department was tasked with evaluating both of these categories. NFPA 30 was reviewed in depth to determine which sections specifically addressed the ability of the storage facilities. 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 the storage facilities. The storage room portion of this review was performed by both a field walkdown (see NFPA 30 Walkdown Checklist portion of this binder (attachmer.t 3)) and a document search. A summary of these results is contained in the NFPA 30 Compliance Evaluation portion of this binder. NFPA 30 Rev. O Page 5 of 8
;n I(,,) Diis evaluation lists the applicable code sections; whether the -installed - (if systems did/did_not comply or if the code sections were not applicable to the-installed. system; and comments or justifications for each noncomplying /not applicable section. This evaluation also has an additional column to 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.
The storage cabinet portion of this review was performed by a field walkdown (see Storage Cabinet Walkdown portion of thiu binder (attachment 3)). A summary of these results is contained in the NFPA 30 Compliance Evaluation portion of this binder. This evaluation lists the applicable code-sections; whether the installed systems did/did not comply or if the code sections were not applicable to the installed system; and comments or justifications for each noncomplying /not applicabla section. This evaluation also has an additional column to identify the documents reviewed for verification of the specific code sections. Once again, one can see that all applicable paragraphs were evaluated for compliance / noncompliance. In addition to the above mentioned portions of this binder, there also exists a " correspondence" section (attachment 1), as well as a section that contains a copy of the 1987 edition of NFPA 30 (attachment 2). 4.0 Conclusions / Recommendations j This evaluation concluded that flammable / combustible liquid storage areas of the Donald C. Cook Nuclear Plant are generally in compliance with NFPA
.30. The storage areas were evaluated against the code requirements of the edition year identified to determine compliance, noncompliance, and open items. Deviation. were 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 could not be justified are identified within this text and their recommendations are identified below.

Oil Room Floor Drains Dato: Friday, November 30, 1990 8:23:06 EST Attach:
'Cartify: N Forwarded by: -The purpose of this message is to summarize the various discussions, regulatory interpretations, and inspections which have occurred as a result of your July _12, 1990 memo regarding NFPA Code 30 compliance in the Cook Plant -. Miscellaneous Oil Storage Rooms.
It.is recognized that the various environmental regulations which apply to the storage of oil and hazardous chemicals are all designed.to ensure that spills are contained. To the contrary, NFPA Code 30 requires that drainage systems be provided to_ direct flammable liquids to a safe location. I&M and AEPSC Environmental pursonnel consulted regarding this regulatory dichotomy agreed t in cases such as this we must simply "do what we can" to comply with the f~' (, Ant of the both regulations.
. Based on this philosophy, three options were discussed:
- 1. Routing floor drain flow within the rooms to new collection tanks
- 2. . Installing CO2 fire' suppression systems in the rooms
-3. Providing curbs around the floor drains Although ccat estimates were not specifically calculated for the first two options, they were dismissed as viable options because of their impracticality, for-a number of reasons. While therofare some drawbacks to the installation of curbs around the flocr. drains, it was agreed that they would provide a reasonable. amount of-protection in the event-of drum rupture, would allow for ; flow of fire protection water fror the rooms, and would be relatively inexpensive to install.
Based on-our meeting on November 29, I understand you will proceed with the curb. design discussed with the Utility Crew (who work in the rooms), and will have the work package added to the existing plant modification to provide ventilation upgrades to the rooms. Please provide me with the drawings of the proposed curb design when they become available, and we'll see thmt they are reviewed by interested partjes at the plant. Let me know if you need any more assistance on'this project. l

- 2) NFPA 30 Code Coepliance Report As you know, Section 4-4.2.11 of NFPA 30 (1987 edition) requires us to exhaust air from a point within 12" of the Flammable Liquid Storage Room's floor with make-up inlets being located within 12" of the floor on the opposite side of the room. It is my understanding that you have initiated a plant modification (12-PM-819) to upgrade the existing HVAC configuration within this room to meet the intent of Section 4-4.2.11.
One exception we are taking to Secticn 4-4.2.11 is the lack of an
,,_ airflow switch interlocked to sound an audible alarm upon failure of the ventilation system. A )uutification allowing this deviation follows, (V)
Per Attachment 1 (psge 3 of 34) of Procedure 1-OHP-4030.001.001, this room is to be tou; by the plant operators. One of the specifics that operators are to look f or is that the HVAC fan is running (procedure step no 2). Cince operators are continuously checking the fan (once per shaft). we feel that we already comply with the intent of this section of dFPA 30. Please attach a copy of this memo to 12-FM-819 for historical records. Return the original to .te ro that the NFPA 30 Code Compliance Evaluation can be updated.

/TP' lb<r' U NOV141990 INDIANA MICHIGAN FIRE PROTECTION Date November 12, 1990 Subied Containment Pequirements From D. M. S'itceraldf To D. L. Baker C. E. Hawk The puroose of this memo is to reauest an evaluation of proonsed alternative means of containment for oil, colluting materials and hazardous waste at two locations at the Cook Plant.
Soecificallv, we utilize the Service Buildina Miscellaneous Oil Storace Room and Turbine Ruilding Oil Storace Room for
/~'\ the storace of bulk oils, solvents, and other V flammable / combustible liquids. The Service Buildino Miscellaneous oil storage Room is also used for temnorar" hazardous waste storace.
The flogr drains in these rooms are routed to the Turbine Room Sump, however, thev are plucced. The doorwaus to these rooms are also elevated at least 5 inches # rom the #1oor level to provide containment cacacitv within the rooms. P. J. Russell of AEPSC Pipinc, HVAC and Fire Protection has informed us that the floor drain plugs must be removed to comply with Section 5-3.4.1. of NFPA Code 30. This code reauires that drainace sustems be nrovided to direct flammable or combustible leakage and fire protection water to a safe location. Two alternate means of comnliance ware suggest bv Dussell: provide curbs a'round the drains
- provide a separate drainaae tank #cr the runoff.
Considering the tank size recuired for the second option (able to contain the laraest expected flammable and/or combustible licuid leak and simultannous fire protection' water discharge), the curbina antinn annears more desirable and [_ more easily implemented (tha rurbs do, however, present a tripping hazard and create drum maneuvering di'#iculties.) (- Both Mr. Pussall and mvso valcone other sucanstions for containment which will s*ill onmniv wieh the NFPA Code. Intra-Symem i a--
4 k . Containment Pecuirements November 17, 1990 Pace 2 Until a more desirable option is found, however, nu snecific cuestion relates to whether the curbina option comn11es with the anolicable environmental reaulations. The reaulations to be considerad include, at a minimum; 40 CFR ll? 40 CFR 265 Michican Admin. Code part 5, Pule 323 uichican Act 64 nules In mv own research on this matter, it was found that Rule 3?3.115 states that a containment area shall be so constracted that no licuid collutina material can escane therefrom hv aravitv through sewers, drains... to the surface water or ground waters of the state. Drovided that we were able to nrovide sufficient capacity per the regulations, does this clause in and o# itself preclude the use of curbs, since the polluting naterial would reach the aroundwater in the avent of drum runture and fire svstem actuation? Perhaps we can cet tocether and brainstorm this issue. I would like to oive P. Russell an answer by the end of November. Thanks in advance for nour heln. lis c: J. E. Rutkowski J.

Thanks. As we discussed the other day, we recognize the need to remove the floor drain plugs from the drains in the Service Building and Turbine Building Misc. 021 storage rooms, for fire protection reasons. We also agreed that constructing curbs around the floor drains in these rooms would allow large quaatities of fire protection water to drain from the room to the Turbine Room Sump in the event of system actuation, but would also serve to contain run of the mill oil or chemical spills in the room. One drawback to the curbing is that they will make it more difficult to maneuever drums within the rooms (possible tripping
<h azard?)
(
\u ver, in researching the regulations regarding the containment volume re.. ired, I'm not sure whether this design would comply with the regc, (For example, Michigan regulations addressing oil spillage containment rec;uire that "the area be so constructed that no oil can escape therefrom by gravity through sewers, drains or otherwise...to the surface or ground waters of the state.") I will ask our corporate Environmental staff for their cpinica on this, and let you know the outcome. How about replacing the fire protection system in these rooms with a CO2 system????

requires that drainage systems be provided to direct flammable or combustible leakage and fire protection water to a safe location. During our NFPA 30 code compliance Evaluation, we noted that the drains within the flammable and combustible liquid storage ooms are plugged. Since we have committed to meet the requirements of NFPA 30 in our 1977 response to Appendix n of BTP APCSB 9 5.1, we recommend that these plugs be removed, Obviously, once the drains are unplugged, we are exposing ourselves to the environmental concerns of allowing oils into the Turbine Building drainage system. We offer the following compromises so that both (ervironmental and fire protection) concerns are adequately covered. o Provide a 2 1/4" curb around the open drain so that the largest expected flammable and/or combustible leak will not spill into tho drainage system unless the fire protection system simultaneously discharges (Attachment 1). Obviously, the chances of this scenario occurring are . e uv v The fire pre-plans can be revised to include a section on the environmental concerns of a fire and simultaneous oil spill in these areas. The pre-plans can also include the clean-up actions needed if this scenario does, in fact, occur. or o provide a separate drainage tank for the largest expected flammable and/or conbustible 11guld leak and simultaneous fire protection water discharge. To assure that all environmental concerns are adequately addressed and that we meer the requirements of NFPA 30. we recommend that you review our proposals and initiate an acceptablu design change to unplug the existing drains within the Flammable Liquid Storage Room (Fire Zone 131) m swen

Sections 4-3.2 and 4-3.2.1 of this code require that portabic storage cabinets remain tightly closed. During our NFPA 30 Code Compliance Walkdown of the plant's cabinets we noted some deviations to these requirements.
Cabinet number 131 2 was noted to have a broken handle and cabinets 44N-1 and 69-1 would not remain closed due to inadequate latches. f-'3/ To assure that all portable flammable liquid c.abinets meet the requirements of NFPA 30, we recommend that you rake the necessary steps to either repair or replace these cabinets. Please respond to us in writing when these cabinets are upgraded into compliance so that we can update the Code Compliance Evaluation.

It should be noted that the classification of a liquid can b'e changed by cortamination. For example, filling a Class II liquid into a tank which last contained a Class I liquid can alter its classification, as can exposing a Class II liquid to the vapors of a Class I liquid via an inter-cornecting vapor line (see 2-2.6.4 and 2-3.5.6). Care shall be exercised in such cases to apply the requirements appropriate to the actual classification. [ NFPA 30 - 1987. , .
