RLTedesco/JKerrigan the Design Margins of the A number of concerns regarding the adequacy of the General Electric Hark III containment design have been raised by Mr. John Humphrey, a former employee of GE.

When these concerns came to the attention of the NRC staff on the Grand Gulf docket, we initiated a series of telephone conference calls and meetings.

While these concerns were first directed by Hr. Humphrey towar ds Grand Gulf, in subsequent discussions he extended his concerns towards other facilities.

After considering Mr. Humphrey's concerns, we concluded that this information is potentially generic an'd may have applicability to all dockets with boiling water reactors which use the GE pressure suppression containment systems (i.e., the GE Mark I, II and III containment systems).

The enclosure to this letter contains 22 categories into which Mr. Humphrey's concerns were coalesced on the Grand Gulf docket as of June 21, 1982, less those items which are clearly associated with a Mark III contairmrent.

In sorrre instances, we have modified an original concern to make it more applicable to the Hark I and II containments and have added some footnotes which generalize Ilr. Humphrey's concerns.

Me request that you respond within 14 days of receipt of this letter wi th your pr oposed schedule for submitting a program to address those concerns which we have identified as being potentially applicable to your facility. If you have arly questions on this matter, please contact the assigned project manager.

Hr. Byron Siegel (301-492-7534) is the contact for operating Mark I facilities and Mr. H.D. Lynch (301-492-9793) is the contact for all other facil~t~es.

This information is being requested under Section 50.34(b)(2)(i) of 10 CFR Part 50 and was approved by $1B under a blanket clearance 3150-0011 which expires April 30, 1985.
