-ABSTRACT '

As requested by PMD (Reference 1), an analysis of flooding due to I postulated high and moderate energy line failures in the auxiliary building of.the Dyron Station was performed. This analysis was carried out to address Item 3 of the acceptance criteria of the NRC-SRP Section 3.4.1 (Reference 2). Fluid release into the various aree of the auxiliary building was-determined by surveying i the high and moderate energy lines (Reference 3) in each area and selecting the line failu're which would produce the worst flooding conditions. The fluid release rate from postulated line failurer was calculated based on the criteria of the NRC-SRP 3.6.1 (Refer-ence 4). The fluid release was accumed to occur for a period of

'30 minutes at which time the leaking line was assumed to be isolated .

Most areas of the auxiliary building would experience a maximum flood level of less than two inches. An exception to this genera.11-zation is the plant area at elevation 343'0" which houses the

( ,e, residual heat removal (RHR) pumps (A&D) and the containment spray (CS) pumps (A&B). This entire area would experience a maximum flood level of 38" for a number of postulated line failures both inside and outside of the area.

I. INTRODUCTION ~

Analyses.were performed to determino the flood level response of the various areas of the auxiliary building to postulated failures of modcrate and high energy fluid systems. To accomplish this, the auxiliary building was divided into 191 1

flooding zones. Twenty-six (26) of these zones were termed

" general areas" which are areas that exhibit large open spaces within the plant and often contain stairwells and hatches which are open to lower levels. One hundred sixty-five (165) of these areas,were termed "subcompartments" which.are smaller .

1 '

areas (generally) enclosed by Seismic Category 1 walls and which open to the general areas only through doorways.

The auxiliary building piping was surveyed to determine which postulated line failures would produce limiting flood levels.

The-fluid release rates woro calculated based on crack or break sizes determined from Reference 4 and the duration of

[]) the release was taken to be 30 minutes. In most casos the blowdown rate was considered to be constant. In other casca, an initia,1 high blowdown rato (based on line inventory) was followed by a smaller rato based on an upstream limiting area.

Fluid removal from general areas was by means of contrally located stairwells or open hatches and to a lessor extent, floor drains. Where no such removal paths woro present, the i fluid 'as w assumed to accumulato within the arca. Fluid removal from subcompartments was by means of floor drains and flow under doors leading to general areas.

Flood levels for the 191 areas' wore calculated for breaks 1 '

within and outside of tho areas of interest and the limiting flood levels were tabulated. The calculated flood lovels woro ,

1 found to bo loan than 2" for most areas in the auxiliary l building. The remaining arcan may be divided into two clanson.

Pagar 8 Project No. 4391-00 4392-00 II. SYSTEM DESCRIPTION The auxiliary building of the two unit Byron Station is a Safety-Category I structure which houses safety-related equip-ment essential to the safe-shutdown of either reactor. This equipment includes the residual heat removal (RH) system, the safety injection (SI) system, the containment spray (CS) system, and the auxiliary feedwater (AP) pumps. The. building also houses a number of systems used in normal plant operations such as the steam-generator blowdown (SD) system.

Postulated breaks or through-wall cracks of piping systems could result in f looding of subcompartments or general areas within the auxiliary building. In many areas the potential flood level is reduced by fluid removal thrcu' hg floor drains and flow under doorways. The floor drain (FD) system is a non-safety-telated system consisting of a network of floor

- drains and drain pipes throughout the auxiliary building.

"' These drain pipes converge to the floor drain sump at elevation 330'0". The floor drain sump pump removes the collected fluid from the sump pit and pumps it to two 8000 gallon floor drain tanks at elevation 364'0". In the event that this pump fails, the water from the floor drains will collect in the watertight floor drain sump room. The volume of this room is approxi-mately 2000 ft 3 (N15,000 gal) and there are two such rooms in the, auxiliary building (one for each unit) .

. METHOD OF ANALYSIS The maximum flooding levels for-the 191 flood zones of the 2 auxiliary building were calculated using a consideration of.

' fluid release to each zone, fluid removal (via stairwells,

~ hatchways,;etc.)-from each zone, and fluid accumulation within each zone. Each of these aspects of flooding is 2

-discussed separately below.

Inflow The maximum fluid release to each zone of the auxiliary building due to a'pos'tulated pipe failure within the zone was

-determined by an examination of various system lines based on the, drawings of Reference 3. Fluid release was calculated for the various lines in question and the line failure found to result in the' greatest release'was designated as the limiting failure. Fluid' systems were classified as eitherL

(.) high or moderate energy systems (References 4 & 5) and differ-

.ent methods were used to calculate fluid release from each-of these systems (see Appendix D).

The design basis fluid release rate from a moderate energy system was based on friction flow through a crack area determined as detailed in Reference 4. This area is calculated for a through-wall pipe crack and is taken as a circular opening with an area equal to that of a rectangle one-half pipe diameter in length and one-half pipe wall thickness in width. Friction flow from a through-wall crack is reckoned using the following equation:

P AP = (3-1) (Reference 6) g where

~T he fluid release rate from a high energy fluid line was determined from consideration of a double-ended break. A limiting flow area was determined for each side of the break.

On one side of the break this was usually a check valve of

(]; zero area'and on the other side, typical limiting areas include flow orifices'and valve seats. The inventory between the break and limiting flow area was modeled as being instantly released to the flood zone and the fluid release rate from that time was calculated based on choked flow at the limiting area.

Outflow Fluid removal from general areas is analyzed by calculating flow through stairwells, hatchways, floor drains, and~under doors. Flow through floor drains and under doors is analyzed using the same methods as are used for subcompartments. These methods are discussed later. Fluid removal by flow down hatchways and stairwells is analyzed as flow over a broad crested wier. The discharge rate is expressed by:

A slope along the free surface of the' flood is required to drive flow toward_the. opening (stairwell or. hatchway). The additional flood height'due to this effect is assessed by

Flow under doorways is analyzed using the minimum flow pre-dicted by either of two models. Method 1 models the flow as flow under a sluice gate and Method 2 models the flow as fr,1ction flow through an orifice. Details are found in Appendix C.

g 4392-00 Flood Level' Calculation

-The-maximum flood level'within an area was calculated using L

one of the four methods described below and detailed in Appendix A.

Method'l accounts for flooding _casos'in which the inflow and outflow are both constants. The flood level is assumed to continuously rise until the inflow is stopped and:

h=(Qg-O)g at/A (3-5)- (Reference 12) where ,

h flood height (ft) 0 1 - inflow (ft /sec) 3 Og - outflow ~(ft 3/sec) g,, At - flow duration (5ec)

A - free floor area of flood' zone (ft 2)

' Method 2 accounts for cases in which the outflow for a flood height of 2" is greater than the prescribed inflow for the zone. In this case, the flood height is said to be "<2" with .

no further specification.

' Method 3 involves situations in which the outflow.is a function of flood height. Eventually a flood height will be reached at which the inflow and outflow are balanced. By calculating this height, the maximum flood level is determined.

Method 4 involves cases in which the outflow is a function of flood height, but in which the outflow is still.lcss than the inflow at the time the inflow is stopped. In this method, credit is taken for outflow which is based on flood heights

'during the transient (i.e., stepwise approximations are made 7;' for outflow during the transient, see Appendix A).

.IV. MODELING ASSUMPTIONS

~

To analyze flooding, the Auxiliary Building was divided-into )

191' flooding zones. 'The' demarcation of these zones was' gen-

'erally:along physical boundaries such.as reinforced concrete walls and doors' . A _ listing of the zones is found in Table 1 and locations of the zones are found-on Figures 1 to 11.

Twenty-six (26) of the ::ones are termed " general areas" which '

are large open areas _usually containing st'airwells-and hatchways I

to lower levels. .One hundred sixty-five (165) of the zones-are termed "subcompartments" which are enclosed areas which pormally contain floor. drains and one door open to a general' area.

, Flooding, analysis requires a specification of fluid inflow, outflow, and accumulation within each zone. The modeling assumptions used in each of these areas are discussed separatelyL q _below.

Inflow Modeling Assumptions Appendix,B contains the methods and calculations used in determining fluid inflow due to postulated line failures.for each of the zones. For each zone, one line' failure was'found-to result'in the highest fluid release for the area in question.

.These limiting failures are listed in Table 1. Assumptions used in obtaining these release rates are as follows:

1) The limiting fluid release rates come from postulated failures of the lines shown on the drawings listed in Reference 3. ,

l 2) Stress 1cvels in certain large moderato energy lines i and certain CV system high energy lines were evaluated 2 s and found to be such that-no line failures need be postulated for these lines (References 15, 16, 17).

- Outflow Modeling Assumptions Appendix'c contains the methods and calculations used in determining fluid-outflow through floor drains, under doors,

.and down. stairwells and hatches. Outflow capabilities assumed for individual zones are shown on Table-1.

J. Assump-

^ tions used in determining the outflows are as follows:

1) The maximum flow through floor drain lines was taken,from:

- Reference 9 as 96 gpm for 4" drain lines and 300'gpm for 6" drain ~ lines. The flow was taken to be'indepen-

, dent of the flood level in the room. Calculations in Appendix C demonstrate the ability of either normal

. floor drains or leak ~ detection sump drains to supply a 4"idrain line with 96 gpm given a flood height of ~ less than 2"..

2) When more than one floor drain was attached to the same 4" drain line, no credit was taken for the extra drain (s) .

The flow was assumed to be limited by the line. Also, in order for a 6" drain line to carry its full capacity,.

it was assumed that it must be supplied by at least s

three 4" floor drains. For further~ explanation and 9 details, see Appendix C.

ci J

Calc. No. ,3C8-1281-001 Reviciont 3 3 Page: 16 Project No. 4391-00 4392-00

3) The total floor drain capacity was assumed to be limited to the. floor drain sump capacity which is 300 gpm for each unit. For the essential service water pump area the limiting drainage was assumed to be the areas' floor drain sump capacity of 100 gpm.
4) All sump pumps in the floor drain system were assumed to fail. Thus, flow was assumed to continue into the floor drain system until the integrated flow equaled the volume of the floor drain sump room (15,000 gal each). When these rooms were calculated to be full, flow into the floor drain system was assumed to be stopped.
5) In calculating flooding within a zone due to a break within the zone, doors leading to adjacent zones were assumed to be closed. For normal doors (not watertight) an opening of 18 sq.. in, was assuraed under each door

(=36" wide x h" clearance) .

6) In calculating the outflow down stairways as flow over a broad crested weir, the width of the '.teir was taken as the perimeter of the stairway opening.

Flood Level Calculation Assumptions Assumptions used in calculating flood level were taken as follows: ,

1) Gross floor areas for the flooding zones are given in Table 1 and are calculated in Appendix C.
2) The free floor area used in Equation (3-5) was taken as 80% of the gross floor area except where noted in Appendix D. Exceptions were made fcr rooms with tar %s where the free floor area was calculated exactly.

, , Revision: 3 Page: 18 3 Project No. 4391-00 g- 4392-00 s-V. RESULTS Results of the flood level calculations are shown in Table 2.

The first column, "30 Minute Flood Level," indicates the maximum flood level due to a line break within the zone of interest. The second column, " Concomitant Flood Level,"

indicates the maximum, flood level from postulated line failures either within or outside of the zone of interest.

Most of the flood zones (132 of 191) have maximum calculated 2 flood levels of 4" or less. As would be expected, most o.f the zones located in the upper elevations of the plant (above el . 4 01 ' 0 ") fall intolthis category (termed Flood Category I).

Zones in this category are typified by areas having no large fluid lines and/or having large floor areas and drainage capacities via either floor drains, stairwells, or door openings.

g Another" group of zones is termed Flood Category II zones.

This designation indicates a maximum flood level of between 4 " and 10" . Of the twenty- three (23) zones in this category, nineteen (19) of them are located at elevation 346'0". The maximum flood levels for these zones arise from a large line failure (48" SX line) followed by accumulation within a large area (the entire elevation).

The last category, termed Flood Category III, involves zones with' maximum flood heights greater than 10". Thirty-six (36) 2 2

zones fall into this category and include the RHR pump rooms (A & B), the RHR HX rooms (A & B), the CS pump rooms (A & B),

the blowdown condenser rooms, and surface condenser room A.

In only one area would a flood in one of these zones cause 1

a concomitant flood exceeding 10" in adjacent areas. A design r J

basis through-wall crack in any of the r.ones RHR pump room (A sor B), or CS pump room (A or B) , would give rise to extensive flooding (up to 38") in the other three connected zones.

As~seen from Table 3, the zones which experience flood-levels exceeding 10" are concentrated in the lower portions

'ofEthe auxiliary-building.-'It should also be noted that none of-the upper floors-in the building-would experien 2

significant flooding. This result. reflects the general design'of systems:within the building with large lines and high' energy systems located .primarily on t:1e lower floors.
