SATAUS OF HATCH SDP ITEMS ON YOUR LIST Dan, I wanted to follow up on my previous e-mail regarding the hatch open items pending SDP.

Currently there are two URIs in the Fire Protection area which are open that will require SDP analysis.

They are:

50-366/03-06-01 URI Concerns Associated with Potential Opening of SRVs (Section 1R05.03.b) 50-366/03-06-02 URI Untimely and Unapproved Manual Operator Action for Post-Fire SSD (Section 1R.04/05.b.1)

Both of these Issues deal with a vulnerability that exists in the routing of cabling associated with the SRVs at Hatch. As a result of this cable routing in certain scenarios SRVs can lift and endanger the licensee's safe shutdown. The first URI deals with the cable routing; the second deals with the licensee's manual actions taken In response to the potential vulnerability. Currently we are trying to determine if there Is a credible fire scenario that could endanger the cables. The geometry of the equipment space Is more involved than the models the inspectors have been provided. As a result the FP folks in HO are running the proposed fire scenario through their more sophisticated model.

Please note that URI 03-06-06 is closed In the current report which Is in routing for concurrence.

If there are any questions please let me know.
