Dear Senator Hayakawa:
m.
a s/
Thank you for your. letter on behalf of Mrs.-Ruth Ann Friedlander regarding s
$[
the safety of. the Diablo Canyon nuclear _ power' plant.
%=:;- -

.4,
The Diablo Canyon nuclear power p.lant is owned by the Pacific Gas.and.-
- T ~
?ctric Company (PG&E), which received permits to build the plant from 2- _.
L... Atomic Energy Commission over ten years ago.
PG&E has applied for a
... ?
license to-operate the reactors and was given a license by the Nuclear f
- Regulatory Commission.(NRC) to' operate Unit 1 at' low power levels.
~
.i ' -
The Comission requires that nuclear plants meet design specifications.to,
withstand earthquakes..
In the case of the Diablo plant, it.was originally designed to withstand earthquakes associated with known geologic faults in the area of the plant.
After the plant was partially built, a previously unknown fault was discovered under water off the coast near the Diablo site.
j The NRC staff did an extens.ive review of the impact of any earthquake associated with this new fault on the plant and imposed new design criteria.. The electric company made a great many modifications in the plant to comply with these Earlier this year, both an NRC licensing board and an NRC j
new requirements.
appeal board found that the new design criteria were adequate and that the plant was built to safely withstand any earthquake that could reasonably be expected in the area..
i Soon after the NRC issued the low power license 'for Diablo Canyon Unit 1, k
errors were discovered in the information used to determine the adequacy of I
the design of certain portions of the plant to withstand an earthquake.
On November 20, 1981, the Nuclear Regulatory Comission suspended the low-power license for' Diablo Canyon Unit 1 pending completion of a specified
. seismic reverification program to the satisfaction of the Commissioners.

I am enclosing a copy of the Commission's order and a copy of a letter sent
.by.Mr. Harold Denton, Director of NRC's Office of Nuclear Reactor Reg 01ation, requesting certain additional information.
.W I hope that this infomation is responsive to your constituent's concerns.
