SUBJECT:
VISIT 'IO SHOREHAM, MARCH 28, 1979 COPIES 'IO:
M. S. Plesset The visit of the Shoreham site was very educational for all of us.
Actual contract with the physical plant is always of valor:. A few comments resulting from my visit follow.
My main purpose was to see how the suppression pool vents and SRV's were supported. The vents are tied together with a matrix of beams.
This should be contrasted with Zimmer where there are no supports.
It came as some surprise to find that the Shoreham design is having some difficulty meeting the requirements of the DFFR. An appeal to both the use of SRS and the ring vortex model may be necessary. 'Ihis will require consideration of both before making any decisions about Shoreham's ability to meet the DFFR.
I noticed that tne control rod drive tubes pass close to the recir-culation piping.
It appeared to me that a little thought could have yielded a better path for the piping.
It is not apparent why it has to be routed past high pressure piping.
v:m control room is of an old design and as a result seems to have something other than the operator in mind. A great deal could be done to improve it from a human engineering point of view.
In light of 'IMI-2, I think it would be worthwhile to see if some improvem,.ts could be made.
I have not reviewed the Shoreham Tech Specs, but would like to do so.
On reviewing several others, I find that the LER program seems to be unrelated to operator training and requalification. 'Ihere are informal channels at most plants for LER's.
It would be better if the process by which relevant LER's are keyed into a plants operations were more formal.
