Dear Yis. Jeffery:
In your letter to Robert Ryan dated Aprfl 9, 1900, yau requested information on the palo Verde Nuclear Generating Station (PVNGS) located approximately 35 nIiles West af Phoenfx, Arizona.
Your first question was concerned fifth spent fuel storage.
PVHGS Units 1, 2 and 3 ~~f'll each include a separate fuel building>>
Each building Mill house a nevi fue'f area, a spent fuel poa'l, a shipping cask area, and a fuel pool cooling and cleanup systen.
The'fuel handling system fs designed to handle the spent fuel unde@later franI the tfme ft leaves the reactor until ft is placed in a cask for shiplent offsfte.
The tfRC has reviewed the design criteria and bases for the spent fuel storage facilities and has found them to be acceptable.
A nore detailed descrfptfon of the spent fuel storage facilities nay be found fn Sectfan 9.1 of-the Palo Verde Final Safety Analysis Report (FSAR).
A copy of the FSAR may be found fn your Local Public Document Room located at the Phoenix Public Lfbrary, 12 East ttc0o>Iell Road, Phoenix, Arizona 85004.
You >>ere also interested fn emergency evacuation plans.
Since the accident at TNI>>2,.the NRC has established a nunber of new requirenents related to er,:ergency planning.
These requirements were developed by the hRC Emergency Preparedness Group in conjunction rsfth the local and state officials at each nuclear plant.
Each plant fs non required to estab1fsh an Krergency Opera-tions Center fram which crftfcal decisions concerning evacuation can be made.
You expressed a concern regarding the "lack of authority" during the accident at TPI-2.
The role of t)RC fn respondfng to emergencies has undergone careful scrutiny during the past year.
As a result of tMs scrut)ny, procedures hav been develo ed which wi11 assure that fn the event of an emergency, ttte"t C

will assist when assible dit ect
<>hen necessar a d f.
FI A second question
><hfch yau raised was concerned v]fth the education and skill level of nuclear plant personnel.
Control room operators are required to undergo an extensfve training program <<hfch includes not only classroom in-struction but also sfrIulatar training.
Prior to obtainfng a license, reactor operators are given examinations by the NRC.
As a result of the TNI-2 accident, the operator training programs have been expanded and fmpraved.
In addition, all reactors are na<< required to have a Shift Technical Advfsor (STA) available at al'l tfnes.
The STA is a trained engineer whose function is ta act as an advisor to the cantrol room personnel fn the event of an errergency.
A number of addftfonal crfter fa, afned at improving the "scan-machine interface",
have been and are being developed by the tlRC.

Ns. Eileen Jeffery JUN? 6 1980 In your last question, you asked for inforaat;ion co",>par ing PIGS with %PI.
The PVEIGS units and TE>ater reactors (PtERs).
HN>ever, there are a number of design differences between PVEEGS and THI.
These differences are due ma)nly because the PVHGS reactors and reactor coolant systems are designed by Combustion Engineering, Incorporated
{CE),
whereas the TEII reactors and reactor coolant systems are designed by Babcock and tii'lcox (BNE).
One of the major design differences fs found in the stean generators which are used to transfer heat out of the reactor.
Systems and components
<Aich contributed to the incident at TEH-2 (e.g.,
auxi'tiary feed>>ater
- system, power-operated belief valves) have been carefully re-evan$ ned by the HRC.
As a resu'lt of this re-examination, a nurser of design changes have been required for a11 reactors, includ'lng PVNGS.
A summary of the actions required of all reactors as a result of'he TNI<<2 accident nay be found in NUREG-0660 "ENC Action Plan Developed as a Result of the THI-2 Accident" A copy of this document can be found in the Loca)
Public Document Room.
Ifyou have any additional questions,-
please contact us.
For your information, the EERC Prospect Panager for PVNS is Janis Kerrigan, tko r;yy be contacted on 301-492-8423 or by tEriting to the BRC, The HRC Resident Inspector for PVENS is Le>>is Vordenbruggen
