@LENN L MOESTER vect entsiotNT huctgan April 12, 1985 Mr. Harold R. Denton, Director Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555 KMLNRC 85-086 Re: Docket No. STN 50-482 Ref: SLNRC 84-0018 dated 2/2/84 from NAPetrick, SNUPPS, to HRDenton, NRC Subj: Containment Sump Screens
Dear Mr. Denton:
Flow criteria associated with the containment sump screens were revised in SNUPPS FSAR Revision 13 which was provided by the Reference. Up to that time KG&E commitments to Regulatory Guide 1.82 criteria had existed unchanged in the PSAR and FSAR since the SNUPPS Utilities responded to PSAR question Q040.15 in 1974.
The change came about when the Wolf Creek Architect / Engineer made final containment flood level calculations and was submitted to the NRC at KG&E's initiative. Recently we have found that the change should not have been made and KG&E now desires to reendorse our former commitments to Regulatory Guide 1.82.
Attached are marked up FSAR pages which reflect those previous commitments.
These pages are hereby incorporated into the Wolf Creek Operating License Application. The FSAR will be formally revised in the first annual Wolf Creek FSAR update.
Yours very truly, GLK:bb

KMLNRC 85-086 1 of 3 SNUPPS Since the containment spray pumps are designed to operate with ('
entrained particles up to 1/4 inch in diameter and the minimum (,j constriction size in the spray nozzles is 7/16 inch, this screening is adequate to assure proper system operability.
Each screening barrier has supports which are designed to h withstand the differential pressure which would exist if the -
screens were 100 percent clogged. Both the screens and the -
W grating are designed'to withstand the differential pressure of 100-percent clogging, and sufficient screen area exists to

It spray pump NPSH. The sump baffle arrangement is shown in -
~g Figure 6.2.2-3.
The sump baffle arrangement does not allow flow into the sump
[ below 6 inches above the concrete floor level surrounding the 2 sump. This arrangement leaves ample depth for buildup of
?[ high-density. debris without affecting sump performance.
Additionally, the velocity of recirculated fluids approaching theatrach rack vill be betreen 0.01 and 0.09 fps - faral-l y med : cf cperation fvilvwing LOCA cr-MSLB 3 _and thus a low g velocity settling region for high-density particles is pro-sq vided.

E Any debris which eludes the baffling, screens, and settling region passes into the sump through the 1/8-inch screen and
-$ will be drawn into the suction piping for the containment y spray and residual heat removal systems. Such debris is small
( enough to pass through any restriction in either: system or the reactor vessel channels, and will eventually be pumped back f'# oqf- into the containment.

- ~ Testing and inspection of components of the CSS, except those s in the spray additive subsystem, are discussed in this section.
Testing and inspection of components in the spray additive subsystem are discussed in Section 6.5.2.4.
_j Each containment spray pump has a shop test to generate com- -
plete' performance curves. The test includes verifying total differential head (TDH) and NPSH for various flow rates. A shop thermal transient analysis, from ambient temperature to 350-F in 10 seconds, has been performed on the CSS pump.
Results of that analysis assure that the design is suitable for the switchover from the injection to the recirculation phase.
