Dear Mr. Lochstet: 

This letter is sent to acknowledge receipt of your petition dated March 29, 
1979, on behalf of the Environmental Coalition on Nuclear Power to suspend 
the operating license for each pressurized water reactor. Your petition is 
being treated under the procedures specified in 10 CFR 2.206 of the 
Commission's regulations. Accordingly, we will inform you of our decision on
your petition within a reasonable time. 

Enclosed for your information is a copy of the notice that will be filed for
publication with the Office of the Federal Register. 

                                        Sincerely, 



                                        Harold R. Denton, Director

                       NUCLEAR REGULATORY COMMISSION 

                     PETITION TO SUSPEND ALL OPERATING 
                  LICENSES FOR PRESSURIZED WATER REACTORS 

                REQUEST FOR ACTION PURSUANT TO 10 CFR 2.206 

     Notice is hereby given that by petition dated March 29, 1979, the 
Environmental Coalition on Nuclear Power, State College, Pennsylvania, 
requested that the Commission suspend all operating licenses issued for 
pressurized water reactors.  The petition alleges that the safety 
evaluations performed for these licenses are invalid, because the incident 
which occurred on March 28, 1979, at Three Mile Island Unit 2, a pressurized 
water reactor, shows that the evaluations of the Emergency Core Cooling 
System (ECCS) for all pressurized water reactors cannot demonstrate the 
performance of the ECCS required by 10 CFR 50.46. 

     The petition is being treated pursuant to the procedures specified in 
10 CFR 2.206 of the Commission's regulations, an accordingly, action will be
taken on the petition within a reasonable time.  A copy of the petition is 
available for inspection in the Commission's Public Document Room, 1717 H 
Street, N. W., Washington, D.C. 20555. 

                                   FOR THE NUCLEAR REGULATORY COMMISSION 


                                   Daniel R. Muller, Acting Director 
                                   Office of Nuclear Reactor Regulation 

Dated at Bethesda, Maryland
this 23rd day of November, 1979.

                Before The Nuclear Regulatory Commission 
                            Emergency Petition 

     The Nuclear Regulatory Commission is hereby petitioned to immediately 
suspend the operating license for each Pressurized Water Reactor (PWR) 
currently licensed to operate.  This petition is brought before the 
Commission pursuant to 10CFR 2.204, 2.206, 50.54 and 50.100.  This petition 
is brought because the safety evaluations performed for these licenses are 
not valid. 

     As required by 10CFR 50.46, each PWR shall be equipped with an 
Emergency Core Cooling System (ECCS) which shall be designed so that its 
performance shall be to respond to postulated accidents in such  a way as to 
limit the fuel temperature as specified in 10CFR 50.46.  This specification 
would not permit the fuel to melt.  These postulated accidents include the 
double-ended rupture of the largest pipe in the reactor coolant system.  All 
PWR power plants are licensed subject to this regulation.  The procedures 
used to demonstrate this performance are not valid. 

     The Three Mile Island Unit II plant is licensed to operate subject to 
this requirement.  On 28 March 1979 an accident occurred at this plant.  The
accident was initiated by an event less severe than the double-ended rupture
of the largest pipe in the reactor coolant system.  The consequence of this 
accident was that at least some of the fuel melted.  This consequence is 
clearly in excess of the performance required under 10CFR 50.46.  Thus, the 
analyses used to predict such performance are invalid.  Thus, it has now 
been established in fact by the evidence of 28 March 1979 at Three Mile 
Island Unit II, that the basis for granting these licenses was invalid, and 
they should be immediately suspended, or revoked.
