20555 Res Phila Eleo. Limerick Gen.Sta. Units 1 & 2.
Pear Mr. Butler, Docket No. 50 0 M M3 As intervenors in the Limerick licensing process under the name R' WVt L.
o Authony/F0E we are referring to the notice in the Fed. Reg, 12/26/85,52874-52876 si dated 1/gned by you and forwarded to ue with anotice fromNRCtag.
R, 27/86 P4:q Following the instructions in the F.R. notice we sent a lot e Secre-tary,NRC, opposing the granting of the exemption requested by Pi$DMp'etiton-ing for a hearing and for leave to be admitted as intervenors to proteistpur safety and health.
On 2/5/86 we followed this up with an amendment directed to the Secretary petitioning a second time to be admitted as intervenors and asking for a hearing.
We trust these petitions will be granted.
what appears to us to be In pursuing our petitions we are handicapped by /26/86 F.R. notice. We ask confusing and,we believe erroneous material in the 12 that you kindly supply clarification.
Furthermore,se have been supplied with a copy of a letter,1/29/86,from M.J.Cooney,PECO, to Robert Bernero,Dir.Div. BWR Licensing NRC.
We are enclosing a copy of this letter which refers to a request for information (RAI) from R.E. Martin,NRC " in support of a December 18,1985 Re quest for Amendment..".
Are we to assume that this is the same letter of 12/18/85:
referred to by you in your F.R. notice,p 52875, from PEco ? We are also enclosing !
a copy of our letter of 1/30/86 to the Secretary and our amendment of 2/5/86.
6 We seek clarification from you on the questions and comments set forth below.
- 1. Letter to R.Bernero, 1/29/86.
Are the NPRDS valves reviewed in TABLE 1 similar to those which are the subject of the Amendment,F.R. 52874 ?
F.R. states that the lines in question " ard small (1 inch or less) " TABLE 1 specifies the sizes 1 " to 12 ". TABLE 2 "is a compilation of information reguarding the valves for which temporary relief of the testing requirement is sought". This table speci-fies 37 valves ranging from three @ 1" to 12 8 8",
8@ 12", and one @ 15". Please explain the discrepancy in sizes between F.R. 52874 and these valves in the tables if this is the same 12/26/85 request for exemption from PEco.
2.
If,as it appears to us, the amenament requested by PEco is the same one referred to in all the documents above will it be necessary to publish a cor-in the Fed. Reg. and po kpone action on the amendment ? We were rected notice /5/86 by the Chief of Docketing that the Project Director will be s
inforged on 2 l
the person to recommend to accept or deny the amendment request.
If this is so, will Mr.R. Martin or any other NRC agent be prevented from acting on PEco's re-quest ?
Since Mr. Martin requested additional information and Mr. Cooney stated that a " multi-faceted program " had he.en undertaken but was incomplete as of 1/29/86, will NRC withhold action until the results of the " program" are in ?
3 Since the subject of the leak test exemption and extention of time limit is a deadline in the regulations which ends on 2/19/86,apparently, will you require PECo to comply with the regulations and the Technical Specifications and proceed to carry out.the required surveillance tests by 2/19/86
?
We repeat our petition to you and the Commission and all agencies of NRC to enforce the Tech.Speo. test requirements and require PEco to stop operating the unit i reactor as of 2/19/86 until the safe operation of the plant can be assessed from tha results of the required valve tests.
We are serving copies of this letter by mail on the Respectfully yours hg, ggg,

January 29, 1986 Docket No. 50-352 Mr. Robert Berner'o, Director Division of Boiling Water Reactor Licensing U.S. Nuclear. Regulatory Commission Washington, D.C.
20555
Dear Mr. Bernero:
The following information is provided in response to a Request for Additio'nal Information (RAI) from-Mr. R. E. Martin, Limerick Project Manager, of your staff, in support of a December 18, 1985 Request for Amendment to the Limerick Operating License and Temporary Exemption. to the requirements of Appendix J to 10 CFR 50.
This request was directed towards supplying information relative to industry experience with valves similar to those which were the subject of the Amendment Request.
In order to support this RAI, a multi-faceted program has been undertaken which includes the following: 1) Review of Nuclear Plant Reliability Data systems; 2) Contact with other utilities identified as having similar valves; 3) Contact with valve manufacturers of the specific valves; and 4) Review of general experience with testing of similar valves at Peach Bottom Atomic Power S tation (PBAPS).
Table 1 (attached) addresses item 1 above.
Items 2 and 3 remain under investigation.
In response to item 4, general experience with similar valves at PBAPS indicates that valve leakage appears to be related to type of service and time in service.
Valves which are used in non-modulating applications, such as those which are the subject of this amendment request, tend not to have problems meeting leakage criteria.
Table 2 (attached) is a compilation of information regarding the valves for which temporary relief of the testing requirement is sought.

Mr. Robert Bernero January 29, 1986 Page 2 The.information gathered thus far has revealed nothing which would alte'r or affect the conclusions contained within our
. application.
Should you have any questions or require additional information, please do not. hesitate to contact us.
Very truly yours,

Kelly, Senior Resident Site Inspector See Attached Service List Table Explanation Results of review of industry experience conducted through Nuclear Plant Reliability Data System Columns 1,__2, 3, 4 Manuf acturer, Model Number, Size and Type of valves which are the subject of the amendment request.
- Column 5 - Similar Number Identified Number of valves identified upon interrogation of NPRD data base.
Search was based upon manufacturer, type and size
' range (e.g. Velan, gate, 2"-6").
Computer generated listing was manually sorted to identify similar model numbers.
If no similar model numbers were identified, the number reported represents the numbers of all valves of same manufacturer, type and specific size.
Column _6_
NPRD f ailure reports were obtained for all valves identified and reported in Column 5.
These reports were reviewed and those f ailures which were relevant to leakage rates and isolation function are tabulated.
It is notable that the reported f ailures concern valves which have been in service for significant periods and were reported to NPRD as " wear-out".
Column 7 Identifies those totals which are reported for all valves of same size when similar model numbers could not'oe identified.
