o SHEET 3 OF 5 OBJECTIVE:

On August 2.1996 a six crop per minute Essential Service water (EF) leak was discovered upstream of valve KJV0786B. The leak is on the 'B" Emergency Diesel Generator intercooler Heat Exchanger drain line just below the seal weld where the 3/4" line connects to the heat exchanger outlet end bell (see Ref.1 through 5).

METHODOLOGY:

Per section C. part 3.a of Genenc Letter 90-05 (Ref. 6) the "Througn-Wall Flaw approach is applied in this evaluation.

The piping configuration is such that it does not restraint against the thermal movement. Thus, the piping stresses due to thermal loading are zero.

PIPE MATERIAL:

Pipe with the " Flaw

• is a 3/4" Dia. Sch. 80, CS, SA 106 Gr. B (see Rcf. 7).

PIPE DESIGN PARAMETERS:

Pipe design pressure is 200 psi and design temperature is 150 deg. F (Ref. 8). For pipe routing and stress calculation see attachment A.

~

FLAW SIZE:

The length of the flaw was measured using both UT (Attachment B) and RT (Attachment C) examinations. The RT results revealed a material reduction zone approximately 3/8"long or less. Thus, the length of the through-wall flaw is conservatively assumed to be 3/8* long.

ASSUMPTIONS:

The weight of the valve KJV0786B is assumed to be 10 lb. The weight of the pipe cap is conservatively taken as 1 lb.

CALCULATION BODY:

The flaw size satisfy the limits of the Section C part 3.a of the Genenc Letter (Ref. 6) for flaw evaluation. Thus, this method is applied here to calculate the required entical stress intensity factor. The calculated factor shall be less than 35 ksi(in) 5 for ferntic steel. The datail of the calculation is shown in the following page.

o SHEET 5 OF 5 CONCLUSION:

The calculated entical stress intensity factor is 3.955 ks:(in) ' which is less than allowable value,35 ksi(in) 5 for ferntic steel. Thus, the structural integnty of the piping with " Flaw is acceptable.
