- On such a basis would the radiant heat load on the raector encl osure not be at least 5 times the loac of 35 Stu, and possibly 10 times or . ore?
Ans.or No. The correct number i s 5,0 00 gallons. In addition, radiant heat depends on burning ra te, d is tance to the receptor, and fraction of heat r ad lated,, rather than total amount of fuel comausted. 05 Stu per square foot per hour is the correct v al ue for this hypothetical release of gasoline. See response to NRC Question 311 13. Also see Calculation ti tl ed "Raciant Heat" .

. And woul d not th is r ad iant heat load impact the diesel gene rat or enclosur es and the diesel fuel storage equally, and accumulote anu generate over several hour s?
Answer P.a i i a n t heat imp inci n<j on tne diesel generator enclosures will gradually warm th e surface lay *- of tne materiel from which these structure s are constructed. The diesel fuel storage tanks are curieu ond woulc not be subj ec t to raciant heat from a fire.
As a metter of per spec ti ve , the warming rate of 95 Stu per square foot per hcur shoulo ce conparea to 440 E tu per square foot per -
hour, which is the human thresholo of pain at that exposure rate, ..
or to a rate of 50 to 60 Stu per square f cot per hour from the sun at midday under a cl oudless sk y. See Calcul ation titled "R ac ian t hea t", (Des ig na ted Di sc ov e ry 10, Item 27).

- How far would ruptur i ng dr a. .,a s from both sides of the rupture before the r iver crossing valves are closed 5 to 10 miles both nortn and south?
Answer The closest manual valves are respectively 0.7? miles scuth and 4.32 mil es nortn o f tne Sc hu yl k i l l River crossing. Tne i compressor stations on either side of the river crossing are at Eagl e, 7.5 mil es sou tn, and near Easton, 37.6 mil es norto. It is conceivable that the entire contents of the pipeline between
'acjacent compressor stat ions cculd be rel eas ed. This is approximatel y 45 mil es o f pipeline. or approximately 40 mill ion cubic f eet o f gas. Gas would fl ow out of both enas of the rupture f or approx imatel y 25 minutes, which is the t ime it tak es to empty the 7.5 mije segment. Gas would then continue to flow at half the ori,ginal r at e from t he 37.6 mile segment for another 200 minutes. See Walsh to ;;cnr tel econ dated 7/21/S3.

Answer
.* !o . The fire would burn at ene rate for 25 minu tes, and at nalt that rate for an addit ional 200 minu te s (see response to Question 33). Radiant heet would impinge on the nearest structures at a rate of 65 ( apercx imatel y 70) 3tu cer sauare foot per hour for 25 minu tes, ano at a rate of 34 Utu per square foot per hour'for the remaining 200 minutes.
