T :eso.kl.vg $2:NPPD Pas.4 of 40 Thursday,Januaryti,iets 3:10:24 PM CALCULATION SHEET 1.0 Purpose The purpose of this calculation is to study the heat transfer rate and temperature profile in dead leg piping. Dead leg piping is piping with no flow which branches off an elevated temperature source. This study will be used to establish criteria for dead leg piping length beyond which temperature increases can be neglected for pressure locking susceptibility evaluations.
Specifically, this calculation will evaluate the temperature profile in the HPCI and RCIC suppression pool suction lines. This information will be used to evaluate the susceptibility of HPCI-MOV-MO58 and RCIC-MOV-MO41 to liquid entrapment (* boiler effect") pressure locking.
2.0 Methodology The analysis will be performed using one-dimensional steady-state heat transfer calculations consdering conduction heat transfer along the pipe and convection heat transfer between the pipe and the surrounding environs. The use of steady-state calculation methods is conservative in that the temperature profile in the dead leg is maximized and the timing considerations associated with transient heat transfer models can be neglected.
2.1 Heat Transfer Model The dead leg piping will be divided into a series of sequential nodes. Heat balance equations considering conduction heat transfer from adjacent nodes and convection heat transfer from the environs will be developed and solved for steady-state conditions. The solution will use finite difference methods which will be solved in an iterative process using a simple computer program.

CALCULATION SHEET 3.0 Analysis The analyses will be performed on the HPCI and RCIC suppression pool suction lines. Muitiple sensitivity studies will be performed using different heat transfer coefficients. The studies will assume an elevated suppression pool temperature of 140*F and an initial ambient temperature of 80*F. These assumed temperatures are conservative in that the maximum post-accident suppression pool temperature is 121 *FSI and maximizing the temperature differential will also maximize the heat transfer rate down the pipe.

Thermal Conductivity, k: 0.654 W/m*CW @ 140*F(assumed) = 0.378 Btu /h.ft*F Three sensitivity studies will be performed. The first sensitivity study will assume the entire dead leg has the thermal conductivity of water @ 140*F. The second study will use a composite thermal conductivity value based on the ratio of cross sectional areas of pipe and water. The third sensitivity study will assume the entire dead leg has the thermal conductivity of steel.

CALCULATION SHEET 4,0 Conclusion The primary conclusion of this study is that the temperature effects of elevated process temperatures diminish quite rapidly along dead leg pipe branch lines. For the "all steel
- sensitivity studies which clearly bound the real case, the temperature gradient is diminished within less than 25' of piping in the HPCI suction line and 20' of piping for the RCIC suction line. Therefore, HPCI-MOV-MO58 and RCIC-MOV MO41 are not susceptible to liquid entrapment (boiler effect) pressure locking due to suppression pool heating.
