TEST REOUIREMENTS:

Articion IWC-5200 and IWD-5200, requiro hydrostatic pressure to bo 1.25 and 1.10 timos system design pressuro rospoctively.

BASIS FOR RELIEP_

Thone requirements do not addronn the different pronsure ratings on the suction and dischargo sidos of pumps and what is to be used as a boundary interf ace.

l Mr. Stovon A. Varga 3-4-86 ALTERNATE TESTING:

Where the renpoetivo synton primary pronsuro ratings on the nuction and dischargo nidon of system pumps differ, l

l the system tont boundary shall be divided into two l separato boundarios (such an nuction sido and dischargo side tent boundarios). In the case of positivo displacomont pumps, the boundary interfaco shall bo considorod as the punp. In the caso of contrifugal pumps, the boundary interfaco shall be the first shutoff valvo on the dischargo nido of the pump.

l This clarification in included in subsequent oditions of ASME Section XI, which havo boon approved by the NRC.  ;

Your approval in nonded for tho ton year System Leakago and Hydrontatic In-Servico Inspection Program. Hocauno of the t largo offort involved, the work han boon scheduled during l anvoral outagon. Somo applicable tents are schedulod for the i next refueling outago which will begin on March 22, 1986.
