Dear Sir:
In Reference 1 the NRC requested extensive additional information concerning the subject modifications.
The Authority responded to this request in Reference 2 and committed to provide the following information: pressure monitor response time and accuracy; water level monitor accuracy; and, hydrogen monitor accuracy and location.
l contains information on the hydrogen monitors.
Information concerning the pressure and water level monitors will be provided to you by June 15, 1983.
If you have any questions, please do not hesitate to contact Mr. J.A.
Gray, Jr. of my staff.
ON Vqry truly yours, 0)q.

e POWER AUTHORITY OF THE STATE OF NEW YORK JAMES A. FITZPATRICK NUCLEAR POWER PLANT ATTACHMENT 1 TO JPN-83-38 DATED May 2, 1983 The accuracy of containment hydrogen monitors is i 5% of full scale.
The monitors are set on a scale of 0-10%, and they also have the capability to be set for 0-30% hydrogen concentration.
The system consists of two redundant trains each capable of obtaining samples from three locations in the primary containment, one location in the suppression chamber, and one location in the reactor building.
Sample locations for both trains are:
1.
Drywell lower level El.276'-6" 2.
Drywell mid level El.310'-6" 3.
Drywell upper level E1.343'-6" 4.
Suppression chamber El.250'-3" 5.
Reactor building El.300'-0" The twc hydrogen analyzers are located on Elevation 300'-0" of the Reactor Building.
The sample point locations for H sample lines in the drywell and suppression pool have been select 3d to adequate indicate the concentration level of hydrogen in the containment.
These locations are representative of the drywell area.
