AFFIDAVIT OF LEONARD 1. LOFLIN IN SUPPORT OF

SUMMARY

DISPOSITION OF EDDLEM AN CONTENTION 75 (BIOFOULING)

STATE OF NORTH CAROLINA )

)

COUNTY OF WAKE )

Leonard I. Loflin, being duly sworn according to law deposes and says as follows:

1. I am Manager, Engineering - Harris Plant of Carolina Power & Light Company, and give this affidavit in support of Applicants' Motion for Summary Disposition of Eddleman Contention 75. I have personal knowledge of the rnatters set forth herein and r '

believe them to be true and correct to the best of my information, knowledge and belief. A summary of my professional qualifications and experience is attached as Exhibit "A" hereto.

2. Eddleman Contention f5 in th'is proceeding asserts that one or more species of clam, oyster or other marine growth (e.g. barnacle) will prove resistant to biocides added to cooling tower water and thus be able to grow and live in the SHNPP condensers creating debris which would foul and block the condensers preventing the plant's access to its ultimate heat sink, with serhus safety consequences. The purpose of this affidavit is to summarize the effects of a complete fouling and blocking of the SHNPP condensers 8309070269 830901 PDR ADOCK 05000400 0 PDR

o on the plant's access to its ultimate heat sink, in support of Applicants' summary disposition n)otion.

BLOCKING / FOULING OF CONDENSERS AT SHNPP

3. If for any reason the SHNPP condensers should become completely blocked with the plant in any mode of power operation (up to 102%) the plant would readily be brought to a cold shutdown condition by use of the Service Water System.

4. The Service Water System consists of both the normal and emergency service water systems. The emergency service water system is designe'd to ultimately remove the core decay heat as well as the heat stored in the primary coolant water. The emergency service water system has two completely independent and redundant trains and is supplied by either the Main or Auxiliary Reservoir. A complete description of the service water system can be found in the SHNPP FSAR Section 9.2.

5. The SHNPP design basis assumes no credit for condenser availability (the main condensers are a non-safety /non-seismic system). The Service Water System, with no reliance upon the condensers, is designed to bring the plant to a cold shutdown condition.

CONCLUSION

6. The complete loss of the SHNPP condensers due to the accumulation of debris, or for any reasc.:. willin no way prevent the plant's accessibility to its ultimate heat sink j and no safety consequences will result.

This the Yday of .
