The IDVP Interim Technical Report 14, dated December 6, 1982, includes temperature and pressure environmental aspects for safety related equipment in the auxiliary feedwater system with respect to a potential main steam line break outside containment.

We request that you provide us with the information listed in the enclosure necessary to calculate the temperature and pressure transients in area GE of the auxiliary building (elevation 115 feet - 0 inch) resulting from a main steam line break in area GW.

We intend to determine, separately from the IDVP, the temperature and pressure profiles for this case for comparison with the IDVP results.

Sincerely,

Enclosure:

PRESSURE AND TEMPERATURE PROFILES FOR PIPE BREAV OUTSIDE COI'tTAINHEt<T The following information is requested for main steam line break analysis in area GW of the auxiliary building (elevation 115 feet - 0 inch) with respect to the tempe'rature and pressure transient in area GE:

1.

With respect to the pipe to be broken; type of fluid (water or steam) h.

temperature c.

pressure d.

source of the fluid e.

flow rate (or assumed flow rate) as a function of time enthalpy as a function of time 2.

With respect to the compartments being analyzed:

3.

a.

number of compartments analyzed b.

for each compartment:

i.

initial temperature ii.

initial pressure iii. initial humidity iv.

floor area including floor space taken by equipment (square feet) v.

number of vents and vent areas (square feet) for each vent vi.

compartment wall height (feet) c.
