AFFIDAVIT OF Robert W. Keaten State of New Jersey )
SS County of Morris
)
Robert W. Keaten
, been duly sworn, deposes and says:
1.
I am Direc tor of the Systems Engineering Depa rtment of GPU Nuclear Co rporation, and have over 20 years experience in the nuclear field, including expe rience in accident analysis.
In my role as Direc tor of Systems Engineering, I have become familiar with the matters stated herein.
With re spec t to this information, I either have personal knowledge thereof, or have been informed of such information by GPU Nuclear Corporation personnel.
I make this affidavit in support of " Licensee's Motion for Clarification, or in the Alternative Reconsideration, of the Boa rd 's Rulings on the Fuel Handing Building ESF, Filter System."
2.
Licensee has determined that tubing within the TMI Unit I steam has been subjected to some chemical attack.
Investigations a re gener i
u nde rway to determine the precise cause of the observed attack.
Equipment fabricated from materials of a type similar to the steam generator tube s is also located in the reactor vessel ar.d may be subject to attack.
As a result, t
Licensee plans to inspect this equipment to determine if it has been degraded.

l
Currently, Licensee plans to accomplish this inspection by removing the reactor vessel head and making progressively more detailed inspections of the reactor vessel and its internals.
If it becomes neces sa ry to remove a substantial number of fuel assemblies, this inspection effort may require defueling of the Unit reactor core and transfer of the fuel assemblies to the Unit 1 spent fuel pool for temporary s t., rage.
3.
Licensee's present intention is to remove the reactor vessel head on April 2, 1982.
No detailed schedule has been established for the remaining portions of the inspection effort.
4.
The Unit 1 a rea of the TMI fuel handling building does not have installed an Engineered Safety Feature ("ESF") filter system satisfying the guidelines of Regulatory Guide 1.52, and such a system could not be installed
'l by April 2, 1982.
5.
In order to assess the potential hazard s from a postulated Unit i fuel handling accident, GPU Nuclear Corporation engineers have conducted an offsite dose analysis conservatively reflecting current TMI-1 fuel conditions.
The analysis took no credit for either filter efficiencies or radioactivity dilution due to elevated release from the fuel handling building ventilation system.
It also assumed that TMI-1 had been shut down and that radioactive isotopes in the fuel had decayed for a period of two-and-one-half years.
All other assumptions and methodology used in the analysis were in accordance with the guidelines of Section 15. 7.4 of the S tandard Review Plan and Regulatory Guide 1.25.
I have attached as Exhibit I hereto a list of assumptions and key parameters used in the analysis.
6.
The results of this offsite dose analysis are as follows:
Exclusion Boundary LPZ
-5
-5 Thyroid dose (rem) 8.7x10 1.7x10 Whole-Body Dose (rem) 6.5x10 1.3x10' 7.
The offsite doses projected from this analysis are very low and represent small fractions of the limits of 10 CFR Part 100.
- Licensee, therefore, believes that the proposed movement of Unit 1 fuel within the Unit 1 fuel handling building, even in the absence of an ESF filter system, poses no undue risk to public health and safety.
Permitting such fuel movements at this time will allow Licensee to make a timely investigation of possible degradation of materials within the Unit I reactor vessel.

(a) 10% of noble gases and iodines from a damaged fuel assembly (total 208 fuel pins assumed to be damaged).
(b) 30% of the K -85 and I-129 inventory is assumed to be released.
p 5.
No c redit was taken for either filter e f ficiencies or radio-activity dilutions due to the elevated release from the fuel handling building ventilation system.
