RESULTS OF EDDY CURRENT MEASUREMENTS IN RINGHALS 3 MAY, 1981 (Ref Westinghouse Report, December,-81)

Background:

Water Hammer Event in FW lines. Scope: 14 tubes in Row 49 inspected by Zetec. Result: No dents on preheater tubes. However, "it was suggested that several tubes exhibited signals, which should be monitored in future inspection". This last conclusion was,however,nct reported to SKI.

SKI POSITION 1. The fretting seen in Ringhals 3 is a new phenomenon, not earlier seen in this type of SG. It is of generic ' nature. 2. The fretting is very fast (leakage af ter < 3 000 EFPH operation). 3. The problem is a safet problem. 3.1 Small primary leaks increase risk for large accidents. 3.2 Risk for multiple tube /SG failure. 3.3 Break of barrier for release to athmosphere (fuel leakage) 4. The problem can most probably be solved. No acceptable solution has, however, yet been given to SKI for Ringhals 3k 5. Plugging according to RG 1.121 not sufficient. Basis is good for initial tube integrity, but analysis is in addition needed for 'l - additional wear l - effect of increased gap (rad gap 0.2 mm, tube thickness 1.1 mm) - lost supports (lower resonance frequency) - loose parts in secondary side (plugged tubes - no indication) l 6. Hydroelastic vibrations have not been shown to be the i only cause of harmful vibration. 7. (Full scale) model tests are very important. 9

Dear Mr. Felton:

Pursuant to the Freedom of information Act 5 USC S 9 (Subpart A), the Critical Mass Energy Project hereby request copies of, and otherwise access to the information detailed as follows: 1. SECY-82-72, "Overall Steam Generator Program," dated February, 1982. 2. Memorandum for Commissioner Bradford from W. J.

Dircks,

" Investigation of the Influence of Simulated Steam Generator Tube Ruptures During Loss-of-Coolant Experiments in Semiscale MOD-1 Systems," a May 1978 paper by EG&G Idaho, Inc. (TREE-NUREG-1213). 4. " Steam Generator Tube Rupture Effects on a LOCA," a November 1978 report by EG&G Idaho, Inc. (CAAP-TR-032). 5. Any and all documents containing information of steam generator operating experience in countries other than the United States. Specifically included in this request are analyses, studies, reports, memorandum detailing recent problems at Almara and Ringhals. Also included in this request are any and all documents transmitted to NRC by foreign governments or corporations concerning abnormal occurances or adverse operating experience with steam generators. The Critical Mass Energy Project is a public interest /non-profit organization. The materials sought are for a study that will be printed in our paper, Critical Mass Energy Journal, and distributed to the press and general public. As the information requested is in the general public interest, we request a complete waiver of all costs you might incur in processing this information or providing us access to it under provisions at 10 CFR E 9, 14a. 215 Pennsylvania Ase., SE a Washington, DC 20003 m (202) 546-4790 hy( .
