Zinner Nuclear Power Station, Unit 1 FR0ft: Robert L. Tedesco, Assistant Director for Licensing Division of Licensing SUBJECT : BOARD NOTIFICATION - AIR PRESSURE LOADS ON THE DRYWELL -
WETWELL VACUUM BREAKERS DURING POOL SNELL FOLLOWING A POSTULATED LOCA (Board Hotification 82- )
In accordance with present NRC procedures regarding Board Notifications, the enclosed information is being provided for your information as constituting new infornation relevant and naterial to safety issues. This infomation is qeneric and may have applicability to all dockets with boiling water reactors having eitner a Mad I or 'iad II type containment. Due to the larger volumes in the Mark III containments, we do not anticipate this matter will affect these f acilities.
Basically, the safety-related caanonents involved are the drywell to wetwell vacuum breakers which can be sub. ject to an air-clearing load resulting fron a pool swell following a postulated loss-of-coolant accident. Various components of the vacuua breaker potentially can be overstressed by an inoact load whose magnitudes are snown on Attachment 1 for seven Mark II facilites. Of these seven, four have Anderson-Greenwood vacuun breakers whose present design might be overstressed at an impact circular velocity of about 10 radians /second.
(Refer to the !1 arch 1982 status in the chronology of Attachment 2).
Attachmnt 3 shows a vacuun breaker configuration typical of the GPE valves.
These three attachments were taken from the infornation supplied to the staff at a meting wi th the Mad II owners in Bethesda, Md., on fiay 20, 1982.

i Two of the three utilities using the GPE vacuum breakers couldn't state at this time wtiether their design satisfied the appropriate structural criteria.
Additionally, the staf f has not yet had the opportunity to review the complex modeling of the fluid-structure interaction used to predict the disk inpact velocities. IIe will continue to actively pursue this natter with the Mart II owners group, including holding additional meetings with the applicants, and will be able to provide an assessment of this phenomenon after receipt of additional information from the affected utilities.
