.The Honorable Shirley Jackson l

Chairperson

. U.S. Nuclear Regulatory Commission l

Washington, D.C. 20555-0001

Dear Chairperson Jackson:

I We have been following closely the developments at Millstone in - particular i

Millstone Unit 2 because it was designed and built by the same NSSS

. vendor i

(Combustion Engineering) and Architect Engineer (Bechtel) as. San =

Onofre Units 2 and 3 (SONGS 2/3) which is only 4 miles from our residential r

j homes - in south San Clemente. We know that the initial design and safety j

analysis for - both Millstone Unit 2 and SONGS 2/3 was done in the early and mid 1970=EDs - by the same management and functional engineering personnel.

Therefore this - leads us to suspect that any nuclear safety concerns at Millstone Unit 2 are - likely to be applicable' to SONGS 2/3. Please confirm that the Nuclear -

Regulatory Commission has evaluated SONGS 2/3 in light of the problems at =

4 Millstone and can assure us the none of the nuclear safety concerns'and l

problems at Millstone exist at SONGS 2/3.

As an example of a nuclear. safety concern at Millstone which maybe -

applicable to SONGS 2/3 consider the following found on the Internet:

l

-ECSteam - generator safety valve'setpoint does not consider piping run. A i

review of the - steam generator design found that the pressure drop between j

the steam - generator and the safety valves was not taken into account in determining the - safety valves-ED setpoint. Thir error was discovered in the analysis for a single MSIV - closure at power. The additional pressure drop could be as high as 100 to 150 - psid. The resulting steam generator pressure would exceed 110% of ASME = design pressure-EE. Other Millstone Unit 2 safety 1

concerns found which maybe - applicable to SONGS.2/3 relate to the spent fuel i

pool, ECCS, LOCA, etc. Please - assure us that none of the Millstone nuclear l

safety concerns and problems exist = at SONGS 2/3. Thank you in advance for your response.
