20555 In the Matter of Metropolitan Edison Company (Three Mile Island Nuclear Station, Unit No. 1)
Docket No. 50-289 (Restart)
Dear Chairman Edles and Administrative Judges Buck and Gotchy:
Pursuant to the procedures outlined in Licensee counsel's letter to the Appeal Board of October 1, 1981, enclosed is a copy of a February 2, 1983 letter from H.D.
Hukill, Vice President TMI-1, to J.F.
Stolz, Office of Nuclear Reactor Regulation.
Mr. Hukill's letter sets forth a proposed alterna-tive method for ensuring that potential exposures from fuel handling accidents at TMI-1 conform to current regulatory guidelines.
As reflected in the Licensing Board's Partiel Initial Decision on Plant Design and Procedures, Unit Separation, and Emergency Planning Issues, dated December 14, 1981, Licensee comIritted to upgrade the Fuel Handling 8302160293 830208 PER ADOCK 05000289 m

Gary J. Edles, Esquire Dr. John H. Buck Dr. Reginald L. Gotchy February 8, 1983 Page Two Building Ventilation System to include a new engineered safety feature ("ESF") filter system prior to the first refueling outage after restart.
The purpose of this upgrade was to bring TMI-l into compliance with the guidance set forth in Regulatory Guide 1.52 (Rev. 2, Ma rch 1978).
Upon further analysis, Licensee now proposes tc satisfy Regula-tory Guide 1.52 guidance b3 2dministratively revising fuel handling procedures to preclude the movemeat of irradiated fuel into the Fuel Handling Building until 12 days after shutdown.
Calculations performed in accordance with NRC Staff guidelines show that such a delay prior to fuel move-ment in the Fuel Handling Building will allow sufficient decay time to keep the dose from postulate 6. accident within i
the numerical guidelines of Standard Review Plan ("SRP")
j section 15.7.4.
Mr. Hukill's letter requests modification of Licensee's commitment to install an ESF filter system.
Respectfully submitted, Robert E.

Three Mile Island Nuclear Station, Unit 1 (TMI-1)
Operating License No. DPR-50 Docket No. 50-289 Engineered-Safety-Feature (ESF) Filter System Tne ASLB Partial Initial Decision (PID) on Plant Design and Procedures dated D2cember 14, 1981 states at Paragraphs 1265 and 1326(a) that GPUN chall upgrade the Fuel Handling Euilding Ventilation System to include a new engineered safety facture (ESF) filter system prior to the first refueling outage. The FID also set:cs that this system will n.aet the guidelines of Regulatory Guide 1.52 (Rev.
', harch 1978) and must be in operation whenever Unit 1 fuel movements are in i
l progress. We request that TMI-1 be relieved of the obligation of meeting this j
requirement.
L I
Ancivses for the radiological consequences of a postulated TMI-l fuel handling I
accident (FHA) have been performed using the assumptions outlined in Attach =ent 1.
These assumptions have inccrporated the guidance of SRP.
15.7.2 and of Regulatory Guide 1.52, Rev. 2 (March 1978) with the exception of the item noted oelcw.
The results of these analyses are given below:
SRP Exclusion 15.7.4 Boundary LPZ Limit 10 CFR 100 Limit Thyroid 75 14.3 75 300 (rem)
' thole Body Dose 0.15 0.03 6.25 25 l
(rem) l As can be seen from the assumptions in Attschnent 1, an elapsed time period of twelvt (12) days (288 hours0.00333 days <br />0.08 hours <br />4.761905e-4 weeks <br />1.09584e-4 months <br />) has been used to provide additional decay time for I
tafimetdyc gasec, and thus, reduced integrated doses (thyroid /whole body) ct L.-th the exclusion boundary cnd low population zone. The time period mentioned GPU Nuciear Corporation is a subsidiary of tne GeretalFuthe Ut'i ties Corce atibn C3^ %C..-,-

Mr. J. F. Stolz 5211-83-023 above represents the time elapsed between reactor shutdown (beginning of hot shutdown) and when the first spent fuel assembly is to be transferred into the Fuel Handling Building.
Current defueling procedures will be amended to preclude moving irradiated fuel into the Fuel Handling Building before 12 days after shutdown.
The above analysis confirms the adequacy of the TMI-1 design with respect to off-site impacts. The ventilation separation modifications inp3 ace at restart 4
assures no adverse impacts inplant from a fuel handling accident in the FHB.
The co=:nitment allows an alternative to the conditions imposed by the ASLB in Paragraph 1265.
Sincerely,
