1.A.
Three nodes (compartments) were used in the analysis. These were the Main Steam Tunnel (MST) - West, the MST - East, and the atmosphere.
1.B.
Initial conditions for each node are provided in the following tabl e.
Callaway FSAR (Wolf Creek USAR) Figures 1.2-15 and 1.2-16 or Figure 38-2 provide the MST compartment height (approximately 62 feet).

1.C.
For a nodalization diagram, refer to Sheet 2 of Figure 38-4 of -
the Callaway FSAR (Wolf Creek USAR).
1.D.
The MST - West was identified in the MSLB superheat submittal 8
of 4/4/86 as the break compartment. All safety-related equipment is
{
located in the lower half of the MST compartments. Relative locations i
of safety-related equipment may be determined from Callaway FSAR (Wolf Creek USAR) Figures 1.2-12,13,15,16; 3B-2 and 3.6-1 (Sheets 1, 2, 3, 29, 30 and 49). However, since worst-case environmental conditions (MST-West) were used in calculating the surface tempera-tures of all equipment without consideration of spatially varying conditions, equipment locations are not a factor in the conclusions stated in the MSL6 superheat submittal.
1.E Table 1 provides the requested information on heat sinks.
1.F In preparing Table 3.4 of the MSLB superheat submittal, nine equip-ment types were modelled.
In addressing the request for additional information, the need to perform a more detailed analysis of one equipment type (Equipment 10) was identified. The ten equipment thermal models are discussed in the following sections. All models are one-dimensional except those for Equipment 9 and 10.

Correlation of the equipment listed on Table 3.4 of the MSLB superheat submittal to the above equipment types is discussed below.
Main Steam Pressure Transmitters - The transmitters correlate directly with Equipment 3.
The model used in the analysis is conservative because the thickness of the transmitter housing is approximately 0.25" instead of the modelled.0747".
Main Steam Pressure Transmitter Instrument Cable - This cable is run in solid and flexible conduit in the MST.
The themal lag response of flexible conduit is limiting. Therefore, the cable correlates to Equipment 5 with a conduit diameter of 0.75".
When comparing the thermal response of conduit, the surface temperature of smaller conduit followed more closely the room temperature than larger conduit. Also, for a given size, flexible conduit followed more closely the room temperature than solid conduit.
I It has been noted that an error existed for this equipment on Table I
3.4 of the MSLB superheat submittal. 2For the feegwater isolation signal temperatures, with break sizes 1.g ft and 0.7 ft, thg temperatyres in Table 3.4 should be 250 F and 245 F instead of the 235 F and 232 F values which are incorrectly picked off the thermal lag curves.
(A
- Page 4 of 27 i
revised Table 3.4 is attached. The table has been revised to correct the i
above error and to incorporate additional changes identified in the follow-ing discussion).
MSIV/MFIV Solenoid Valve.- The valve correlates to the curves for a Skinner solenoid valve (Equipment 10).
Revised qualified and thermal lag temperature values have been incorporated into Table 3.4 based on revised qualification data and a two-dimensional analysis for this solenoid valve.
MSIV/MFIV Wiring and Lugs - This equipment is locatM inside terminal boxes mounted on the MSIV and MFIV actuators. The one-dimensional terminal
+
box response curve (Equipment 2) was conservatively applied to this equip-ment.
MSIV/MFIV Terminal Blocks - The terminal blocks correspond to Equipment 9.
lWsed on an examination of the lumped-heat-capacity anapsis for the i
terminal box, it was found that results from thg 1.0 ft MSLB enveloped those of the other breaks, including the 0.7 ft break, at all' times 2
until the end of the analysis for the 1.0 ft MSLB (800 seconds). For this reason, the detailed two-dimensional analysis was performed only for this break. Moreover, since the temperature of the terminal block remained below the qualification temperature for the entire duration of the two-dimensional analysis, the results were considered bounding and conservative.
Tngs the terminal block temperature response was determined for the 1.0 ft break using a two-dimensional analysis.- The equipment tempergttrres for the other size breaks were determined as follows. The 1.0 ft 2
temperature response fcr the terminal blocks was compared to the 1.0 ft response of the terminal box (Equipment 2).
Itwasnotedghattheterminal block response lagged the box response by approximately 85 F in the time period of interest.
Since the terminal block temperature response is drfven by the terminal box response, it was assumed that the approximately 85 F difference in temperature puld exigt between the tgrminal block and the terminal box for the 4.6 ft, 0.7 ft and the 0.5 ft cases.
In this way, the terminal block temperature values for steam line isolatioa in l
Table 3.4 of the submittal report were obtained from the Equipment 2 thermal lag curves.
j For the feedwatgr isolation temperatures in Table 3.4, it was assumed that the 4.6 ft break temperature was tge same as for steam /line isolation (thisassumptionwagusedfortge4.6ft break case for all equipment);
i and, for the 0.7 ft and 0.5 ft cases,thetempegatureoftheterminal bigckwasassugedtoinc5easeatacnstant
.65 F/second from the 1.0 value (135 F). 2 65 F/second is the maximum terminal block rise 0
ft rate for the 1.0 ft break.

MSIV/MFIV Control Cable - This cable is run in conduit and flexible conduit in the MST. The temperature correlates to the thermal lag values for 1.5" flexible conduit (Equipment 6). The submittal Table 3.4 values for this equipment have been revised to reflect actual thermal lag values for the four break sizes. The values previously provided were based on an average of thermal lag values for 0.75" and 2" flexible _ conduit.
MSIV/MFIV Limit Switch - A thermal lag curve was not specifically developed for a limit switch.
It was assumed that a limit switch housing thermal response would be similar to the resporise of the solenoid valve solenoid housing (Equipment 1). This assumption is appropriate because the thickness of a limit switch body (approximately 1/8") is equal to the thicknets of the modelled solenoid valve solenoid housing. For a sketch of a limit switch refer to Figure 17.
MSIV/MFIV Conax Connector - These connectors correlate to Equipment 4.
MSIV/MFIV Limit Switch Instrument Cable - Portions of this cable are routed 4
i in 0.75" Able hose.
Tnerefore, the thermal lag response curve for Equip-ment 7 is appropriate for this cable.
J-601A Solenoid Valve - This valve correlates to the curve for a solenoid j
valve body (Equipment 8).
J-601A Control Cable - This cable is run in conduit and flexible conduit in the steam tunnel and correlates to Equipment 5.
Question 2 1
All assumptions used, including but not limited to the following:
2.A.
Junction loss coefficients; 2.B.
Heat transfer coefficient for heat transfer through walls; 2.C.
Condensation model used.

Response
2.A.
Assumptions used in the MSLB superheat submittal concerning mass and l
energy release, environmental conditions and equipment performance are discussed in sections 3.1, 3.2 and 3.3 of the submittal. Additi-onal assumptions pertinent to environmental conditions and equipment performance are:
j a.
Cooling by the MST ventilation system is conservatively neglected.
b.
Owing to their low failure pressure, the MST blowout panels open soon into the transient. Hence, they are modelled as simple open i
vents.
c.
Thermodynamic equilibrium exists at all times in the MST compart-ment atmosphere. Page_6 of 27 i
. -=
l I
l d.
The MST volume is filled with a homogeneous mixture of air, steam and water.
e.
Air is treated as an ideal gas, and steam is treated to second order in the virial expansion of the equation of state.
f.
Flows between compartments are calculated using steady state compressible flow equations for an ideal gas; inertial effects and vapor dropout are not considered.
g.
The junction loss coefficients between nodes have been calculated using simple contraction and expansion losses.
2.B.
For convection, the heat transfer coefficient was calculated based on a velocity, a characteristic length, and the compartment thermodynamic conditions.
Hilpert's Equation was used to evaluate the forced convection heat transfer coefficient based on a Reynolds number at i
film conditions.
If this heat transfer coefficient was less than its natural convection counterpart, then the natural convection heat transfer coefficient was used assuming turbulent conditions (Ref.
NUREG-0588, Rev. 1).
2.C.
For the condensing heat transfer coefficient, four times the Uchida heat transfer coefficient was used (Ref. NUREG-0588, Rev. 1).
Question 3 Analysis results:
4 3.A.
Compartment temperature versus time curve (peak temperature specified);
3.B.
Compartment pressure versus time curve (peak pressure specified);
d 3.C.
Equipment temperature versus time curve (peak temperature specified) for each piece of equipment; 3.D.
Equipment qualification temperature; i
3.E.
Identification of locations for A., B. and C.,
if spatially varying i
within a compartment.
Response
3.A.
Compartment temperature versus time curves were provided in the MSLB superheat submittal, Figures 3.2-1 through 3.2-4.
l 3.B.
The petk pressures achieved in the MST for the MSLB superheat analysis are provided in section 3.2 (page 4) of the MSLB superheat submittal.
These pressure values are lower than those calculated by an analysis that maximizes pressure (rather than temperature) conditions.
Therefore, reference is made to Figure 3B-5 of the Callaway FSAR. (Wolf Creek USAR) for the worst case pressure versus time curve for the g
i MST.
i
' 1 Page 7 of 27 I
3.C.
Worst-case equipment temperature versus time curves are provided, for each of the ten equipment types identified in the response to question 1.F., in Figures 1 through 10.
The worst-case temperature values provided in Table 3.4 of the submittal report are obtained by using the curves and the appropriate actuation time for the equipment. The actuation times, for steam line isolation and feedwater isolation, are listed'in Table III.B-4 (cases 59-63) of WCAP-10961-P except that manual steamline isolation is assumed to occur 600 seconds after reactor trip and allowance is made for steamline isolation valve closure time, i.e. the time from receipt of a closure signal until the valve is fully closed.
3.D.
Equipment qualification temperatures are provided on Table 3.4 of the MSLB superheat submittal (last. column on table).
3.E.
As discussed in the response to question 1.D. above, spatially varying conditions were not assumed in the analysis.

f Hoffman NEMA Type 4 JIC Boxes are designed for use in areas which may be regularly hosed down or are otherwise very wet. They
)
are suitable for use in dairies, breweries, and similar installations.
These boxes are fabncated from 16 gauge and 14 gauge steel and have external screw clamps on three sides of the cover. The screw clamps are quick and easy to operate and have no loose parts. The l
continuous hinge has a stainless steel hinge pin. The solid neoprene h
gasket is attached to the cover with oil-resistant adhesive. Cover clamps and clamp screws are stainless steel. All seams are continu-ously welded and there are no holes or knockouts. External feet are y
furnished for mounting. The standard finish is gray enamet inside and out over phosphatized surfaces. Additional fansshing of the exte-rior is necessary if the box is located in a wet area. Weldnuts are provided in 6 x 4 and larger sizes for mounting the optional panels and terminal kits which must be ordered separately. When ordenng special "CHNF" boxes, be sure to completely specify the hanging arrangement. These boxes conform to the NEMA standard fortype 4 g
(Watertight and Dusttight) and Type 13 (Oiltight and Dusttight) enclosures, and to JIC standard EGP-1-1967. All boxes are listed by Underwnters' Laboratones, Inc.
