Dear Mr. Callan:

~

l 4

l I'm enclosing copies of. letters I recently~ received from one 1-of my constituents, Joseph Stankowski, regarding his further

j. concerns about NRC examination of' primary piping welds and reactor. coolant piping welds at the Millstone 3 reactor (see 1

enclosed the NRC). letter of November 26, 1996 sent to my constituent by Mr. Stankowski Senior Engineer for a p~eriod workedof 14 years. at Northeast Utilities as a 1

l My constituent is concerned about any regulator request that may be granted to Northeast Utilities. According y relief to

~

l my constituent. the critical welds in the piping that goes from 1

the reactor vessel to the reactor coolant pumps cannot be l inspected ultrasonically as required by regulations because '

Northeast Utilities and the NRC approved of the material from 4

i which the piping is fabricated -- material with a large grain structure. My constituent contends that these welds can be 4

examined by x-ray, but Northeast Utilities doesn't support this ,

approach because it would have to drain the water in the pipes --

a process that would be time-consuming and costly for the utility.

He further states that the welds that are not i

accessible could be monitored using acoustic emission techniques.

i* I would appreciate a response concerning each of these points.

j.

a Thank you for your attention to this matter.

a S trely, i

n kYi On a related matter, I was pleased that the NRC has sharply \,

facilities from safety and other regulations. curtailed I have been its policy urging relating -' to 4

this change in policy since April 1994 because the' old policy

• appeared to amount to a de facto license amendment without

, following proper procedures. The new policy ensures that this type of exemption will only be granted in very limited ,

... . circumstances where safety is not an issue.
