Ell /IE The f.'uclear Ecuulatory Conuission has received additions! information frc;n its inspectors at the Three Mile Island Pv,.or Plant in Pennsylvdnia J

where an accident occurred earlier today.

This updates the liRC announce-trent maele earlier today,

~

a No injuries have been reported.

Lou levcis of radiaticn have been 1

I l

measured off the plant site.

The m.iximum ccnfirmed radiation reading war, about three milliroentgens per hour abouc one-third mile from the site.

1 At one mile, a reading of cne railliroentgen per hour was measured.

It is believed that this is principally direct radiation coming from radioactive raterial within the reactor containment building, rather than from release 1

of radioactive matr. rials frc ' the containment.

Extensive efforts are continuing by the State of Pennsylvania, the Department of Energy, and the NRC to measure the amount of radioactive material which may have been i

released frca the site. A helicooter with special instruments also is beiry i

used, j

It now appears that the cause of the turbine shutdoun at the plant early tcday was a reduction in flow of fendvater to the steam generators.

I The sequedce of events which led to the release of' radioactivity to the reactor containment build ~ng has not been detemined.

There was a release of primary ccolant voter to the containment.

Emergcncy core w

. cooling systems are continuing to provide wacer to cool the fuel. The rr. actor is shut down.

The pressure in the reactor systcm is being sicwly cduced.
