1.0 INTRODUCTION

SB 1 & 2 PSAR Alllendmen t 56 November 1985 It is necessary to demonstrate that equip11ent used to perfora a required safety function for Seabrook Nuclear Station - Units 1 & 2 are capable of functioni.ng properly in the normal, abnormal, or accident enviroDDental conditions to which they could be exposed. As stated in NUUG-0588(1), among these enviromaental conditions are the elevated te~erature, humidi t,., and/or pressure which could result from the postulated rup.ture of high energy lines which may be in the vicinity of thie equipaent. Tbe purpose of this study is to evaluate the co118equences of high energy line breaks outside containment and develop the enviro1111ental envelopes for Class lE equipaent. 31-1

2.0 METHOD OF ANALYSIS SB 1 & 2 PSAit Aaendment 56 Noveaber 1985 Each of the high energy linea and all of the Claaa lE equipment outside containment were identified and located. Baaed on this infonaation, the various plant buildings were nodalized and the high energy line break (BELB) locations chosen in such a way as to provide an accurate representation of the environmental conditions that would result in the vicinity of the Class IE equip.ent following a postulated BELB. 2.1 Mass and Energy Releases Each high energy line was evaluated on the basis of the methods of Standard Review Plans 3.6.1 and 3.6.2(2) to deteraine the types, areas, and locations of postulated ruptures that would result in the most severe environmental conditions at each of the Class lE equip-aent. The break releases were calculated using the Moody critical flow model(3) and accounting for physical restrictions within the system (e.g. flow and pressure control valves) and the frictional effects of the piping systea. These release rates were taken to be constant, i.e. no decay of the reservoir pressure was assu.ed, until isolation of the ruptured line was initiated or, as in the case of the closed Bot Water Beating Systems, until the piping inventory was depleted. ~e methods and assuaptions eaployed in calculating the aass and energy release rates for each high energy line are outlined in Table 2.1-1. As noted in this table, isolation of aany of these lines will be accomplished by the use of redundant teaperature detectors in various plant areas that, in the event of elevated teaperaturei, will send closure signals to redundant isolation valves present in the 3!-2

SB 1 & 2 fSAR Amendment 56 November 1985 high energy lines. The locations of these temperature detectors are provided in Figures 2.1-1, 2.1-2, and 2.1-3. The mass and energy release rates used in evaluating the pressure, temperature, and huaidity responses throughout the various plant areas are calculated and defined in References 6, 7, and 8. 2.2 Pressure/Temperature/Huaidity Transients The environmental conditions that result due to postulated high energy line ruptures were determined* for the following areas:

1. Primary Auxiliary Building (PAB)
2.

Contaim~ent Enclosure Area ( CEA)

3. Fuel Storage Building (FSB)
4. Main St;eaa/Feedwater Pipe Chase
5. Tank FBI11 Area (TFA)
6. Waste Processing Building/Primary Auxiliary Building (WPB/

PAB) Chase For BELB other than Bot Water beating Line Breaks (BWHLB), the envir-onaental Responses of the PAB, CEA, TFA, WPB/PAB Chase, and KS/FW Pipe Chase were calculated using the COMPREss(4) coaputer prograa. Using the break mass and energy releases and the building nodaliza-tiona discussed previously, COMPRESS calculates the transient pres-sures, temperatures, and huaidi ties that would occur throughout the plant building following these ruptures. The.ethods and assumptions used in these pressure/ temperature calculations agree with those of NUREG-0588(1). Table 2.2-1 lists the ambient conditions, building initial conditions, and other pertinent design basis information used in analyzing these environmental transients. The ambient and initial conditions were 3I-3

SB 1 6 2 FSAR .AIIIendmen t 56 November 1985 chosen so as to maximize the temperature response that would result from these postulated HELB. In addition, the Uchida condensing steam heat transfer correlation is used during the condensing mode while a convective heat transfer coefficient of 2.0 Btu/hr-ft2-°F is used otherwise. The environmental response of the PAB, CEA, and PSB to postulated HWHLB was calculated using a reasonable, yet still conservative, hand calculation method which accounted for mass and beat transfer between the hot water and the room air. Since the HWH subsyste.s are closed systems which will not be isolated and these plant areas are supplied with ventilation air by non-class lE systems, the maximum temperatures and humidities that result from BWHLB are calculated by releasing the total HWH subsystem fluid mass into the initial rooa air 1188&. The building initial conditions were determined based on the histor-ical distribution of ambient conditions which occur during the ti* of the year when the HWH system is in operation (September through May). These conditions are defined in Table 2.2-1. JI-4

3.0 BELB ANALYSES AND RESULTS SB 1 & 2 PSAR Alllendment 56 NoYe~aber 1985 The environmental response of the plant buildings to postulated high energy line ruptures were calculated using the methods outlined in Section 2.0. The results of these RELB analyses (other than BWHLB) are presented in the following sections. 3.1 Primary Auxiliary Building From an evaluation of each of the high energy lines in the PAB and their operating conditions, it was concluded that the break locations listed in Table 3.1-1 would provide emrironmental envelopes for the Class lE equipment. Figure 3.1-1 shows the layout of the PAB and the zone designations which were useful in defining the environmental parameters throughout the PAB. Zone 32A, which is not shown, represents the PAB below the the (-)6' elevation and includes the piping tunnels, Zone 32B repre-aents the 2' and (-)6' elevations, and Zones 32 and 33C, 32 and 33D, and 32 and 33E represent the 7', 25', and 53' elevations, respective-ly. Zones 47 and 48 represent the Chemical and Vol~ Control System (CVCS) equipaent vaults and contain no Class lE equipment. Table 3.1-2 suamarizes the peak and enveloping te.peraturea and pres-aures that would occur in each of these zones for each postulated high energy line rupture. All area& can be taken to experience 100% relative huaidity, condensing environments, however, air displacement and thus essentially pure steu enviro011ents would be expected to occur only in the general vicinity of the postulated breaks. JI-5

SB 1 & 2 PSAR Amendment 56 November 1985 For each of the ruptures considered in these tables there follows a aeries of four figures, lettered A though D. The A series of these figures (e.g. Figure 3.1-2A, 3.1-3A) physically defines the nodal arrangement which was chosen to analyze the rupture's effect on the PAB environment. The B series provides the flow diagrams and physical paraaaeters (volumes, beat sink areas, flow areas) for this nodal arrangement. Figures C and D provide the calculated temperature and pressure transients for each of the nodes defined in the A and B aeries figures. 3.2 Containment Enclosure Area The Contaimaent Enclosure Area contains several high energy (eves) lines, however, only the letdown line operates at an elevated tem-perature. Therefore, only a rupture of this line has been considered as stated in Table 3.2-1. The layout of the Containment Encosure Area, which includes the Mechanical Penetration Area, the Charging Pwap Cubicles, and the Residual Beat Reaoval (RHR), Safety Injection (SI), and Containment Spray (CBS) Vaults, is shown in Figure 3.2-lA, Sheets 1 and 2. These figures also show the nodal arrange11ent used, while Figure 3.2-lB provides the corresponding flow diagram and physical parameters. Table 3.2-2 summarizes the pressures and temperatures experienced in the various areas of the enclosure volume following a postulated eves letdown line break. Figures 3.2-lC and 3.2-lD show the transient temperatures and pressures in the CEA. By a variation of the aaau.ed initial conditions (10% va. 95% relative huaidity), an additional investigation was made which determined the maximum pressure response of the CEA. This result is shown in Figure 3.2.-lE. For the HELB 3I-6

SB 1 & 2 PSAR Amendment 56 November 1985 temperature detection system is use, the peak pressures correspond to approxiaately 95 seconds after the break. These peak pressures are listed in Table 3.2-2. The relative humidity throughout all CEA compartaents would reach 100%. 3.3 Main Steam/Feedwater Pipe Chase The breaks evaluated for the Main Steaa/Feedwater Pipe Chase are listed in Table 3.3-1. It was concluded that the MS line breaks will result in 1l0re severe environmental conditions than the FW line breaks. Figures 3.3-lA and 3.3-lB define the MS/FW Pipe Chase arrangement and nodalization. The MS/FW Pipe Chase reaches a maximum of 325°F for a spectrum of MS line break sizes from 0.10 ft2 to 1.0 ft2. The t~ perature transient resulting from a 0.10 ft2 break is provided in Figure ~.3-lC and the results are summarized in Table 3.3-2. 3.4 Tank Farm Area The break evaluated for the Tank Farm Area is listed in Table 3.4-1. Since no HELB temperature detectors are located in the Tank Farm Area, the Auxiliary Steam line break releases will continue until the operator detects the break and isolates the line. Figure 3.4-lA defines the nodal parameters used for the Tank Farm Area HELB analysis. The resulting tewaperature and pressure transients are provided in Figures 3.4-lB and 3.4-lC, respectively, and the peak values summarized in Table 3.4-2. 3!-7

SB 1 6 2 PSAR. Allendmen t 56 November 1985 3.5 Waste Processing Building/Primary Auxillary Building Chase The WPB/PAB Chase, which is located between the WPB.~nd ColWIIIl Line A of the PAB, contains both Class IE equipment and several Auxiliary Steam and Condensate linea. Tbe line ruptures which have been eval-uated are listed in Table 3.5-1. Figure 3.5-lA defines the nodal parameters used for evaluation of the WPB/PAB Chase response to postulated BELB. Figures 3.5-lB and 3.5-lC provide the temperature and pressure transients that result for the enveloping BELB. The peak values for pressure and te~~perature are suamarized in Table 3.5-2. 31-8

4.0 HWHLB ANALYSES AND RESULTS SB 1 ' 2 PSAR Alaendment 56 Noveaaber 1985 The environmental response following postulated BWHLB has been ca1.culated for those plant buildings with Bot Water Beating (BWH) systems which operate in the high energy region, i.e. pressure greater than 275 psig or temper-ature greater than 200°F. The HWBLB postulated are listed in Table 4.Q-l, The results of these BWBLB analyses are presented individually in the follow-ing sections and are summarized in Table 4.o-2. 4.1 Primary Auxiliary Building The peak environmental conditions at the 53' elevation of the PAB due to postulated HWBLB were found to be ll0°F with a relative humidity of 100%. These conditions are enveloped by the consequences resulting from other BELB postulated to occur in the PAB. 4.2 Containment Enclosure Area The BWB system piping which serves the PAB and FSB passes through the CEA. A postulated rupture of one of these lines results in tempera-tures and relative humidities throughout the CEA of approxi11Ultely 106°F and 100%, respectively. Due to the location of this piping, very localized conditions may be slightly more severe although the large recirculation air flows will tend to mitigate these effects to a certain extent. With the exception of these localized effects the environmental conditions that result from a eves letdown line break will envelope those resulting fr011 a HWBLB. 4.3 Fuel Storage Building Since the hot water heating piping are the only high energy lines present in the FSB, the environmental conditions that result from a postulated HWBLB will define the enveloping conditions for high 3I-9

SB 1 & 2 PSAR Alendment 56 November 1985 energy line ruptures. The resulting enviro1111ental conditions are lOODF with a 100% relative humidity. 4.4 Emergency Fee~ter Pumphouse Since the hot water heating piping are the only high energy lines . present in the EFWPR, the environmental conditions that result from a postulated HWHLB wtil define the enveloping conditions for high energy line ruptures. The resulting environaental conditions are aa*F with a 100% relative buaddity. 4.5 Service Water Pumphouse Since the hot water heating piping are the only high energy linea present in the SWPH, the environmental conditions that result fro* a postulated HWHLB* will define the enveloping conditions for high energy line ruptures. The maximum temperature that would be expected to result in the SWPH is 9o*r. Due to the relatively large room volume and 81U.ll volume of hot water heating piping for the SWPR, the maximum relative humidity that is expected to result following a HWHLB is 90% 3I-10

5.0 CONCLUSION

S SB 1 6 2 PSAR Amendment 56 November 1985 The analysis of high energy line ruptures outside containment has yielded a realistic evaluation of the elevated temperatures, pressures, and humidities that can result in the various buildings of Units 1 and 2. These results provide the HELB enviromaental envelopes for evaluation of the Class lE equipment. These envelopes should be evaluated along with the conditions that result following postulated -.oderate energy line breaks, loss of ventilation air flow, and any other events which aay cause adverse envir-onaental conditions to develop. 31-11
