Dear Mr. Ray:
SUBJECT:
NRC BULLETIN 89-02 (TAC NO. 74307)
The staff has reviewed your August 13, 1990 response to NRC Bulletin 89-02, "Stress Corrosion Cracking of High Hardness Type 410 Stainless Steel Internal Preloaded Bolting in Anchor-Darling Model S350W Swing Check Valves or Valves of Similar Design." In your response, you stated that during your review of the safety-related check valves at SONGS 1, your review confirmed that neither Anchor-Darling Model S350W swing check valves nor any other check valves of similar design are used in safety-related applications. Therefore, we consider this matter closed and review activities under TAC NO. 74307 completed.
