Clark, Chief Operating Reactors, Branch 3 Gentlemen:
DOCKETS 50-266 AND 50-301 ADDITIONAL INFORMATION NUREG-0737 POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 This letter is to advise you of our failure to complete 1
installation and place in operation certain portions of the radioactive monitoring equipment in accordance with our schedule i
for compliance with NUREG-0737, Item II.F.1.1,
" Noble Gas Monitoring",
and in accordance with the Commission's Confirmatory Order of March 14, 1983.
We apologize for our failure to notify you of this omission in a more timely manner.
There was of course no violation of Technical Specification or limiting condition for operation.
As you will recall, the Commission's Confirmatory Order of March 14, 1983 confirmed Wisconsin Electric's schedule of i
(
December 1982 for installation of the noble gas monitoring equipment discussed in our July 20, 1982 letter.
Since our implementation date i
for this item was scheduled prior to the issuance of the Confirmatory Order, Attachment 2 to the Order listed this item as complete.
On May 17, 1983, an NRC Inspector brought to our attention that four of the eight monitors which comprised our response'to Item II.F.1.1 were not installed and operating at the time of the March 14, 1983 Confirmatory Order, and, uhus, this item was not, in fact, complete as of the date of the Order.
As discussed in our letter dated April 26, 1982, our provisions for accident monitoring of noble gas effluents consist of the installation of three SPING 4 monitors, one on each unit's
(
containment purge exhaust stack and one on the auxiliary building O

Mr. H.
R.
Denton May 25, 1983 exhaust stack, one SPRING 3 monitor on the radwaste packaging area exhaust stack, and four SA-11 monitors which view the main steam line upstream of the safety valves to monitor steam releases.
As discussed in our letter dated July 20, 1982, the four SPING noble gas monitors were scheduled to be installed and operational on temporary power supplies by August 31, 1982.
The SPING's were intended to be operated on temporary power until the new station battery installation is complete.
In subsequent internal reviews of the NUREG-0737 response schedule in early 1983, we mistakenly overlooked that the noble gas monitoring Item II.F.1.1 commitment included both the SPING and SA-ll monitors.
Rather, the SA-11 monitors were considered to be associated with installation of other monitoring equipment referred to in our letters dated September 14, 1981 and April 26, 1982.
We have determined that this failure was due, at least in part, to the fact that our July 20, 1982 letter did not address these SA-ll monitors, which are the items in question, although they had been covered in our previous letter of April 26, 1982.
Since the SPING monitors were installed and operating, Item II.F.1.1 was erroneously considered completed as previously committed.
Presently the SA-ll monitors are physically installed, i
and two of the four are operating on temporary power.
Physical installation of the Unit 2 monitors was completed in February 1983.
The Unit 1 monitors were installed during April 1983.
Electrical hook-up to the monitors was completed for Unit 1 in April 1983, and for Unit 2 by mid-May 1983.
We are presently repairing the two non-operating monitors and completing the calibration procedures.
We expect to have all four SA-11 monitors operating and calibrated by June 30, 1983.
Please note that while all the new monitors are to be operating in accordance with the schedule described herein, there is other final work associated with this installation that would remain to be completed after June 30.
These activities, which do not affect the operability'of the monitors, include such items as integration of the new apparatus into plant procedures, refinement of calibrations, completion of operator training, preparation of Technical Specifications, resolution of any problems identified during the initial operating phase, and provisions for permanent power supply.
A similar observation is applicable to the two isokinetic stack samplers provided in response to Item II.F.1.2; the samplers have been installed and operating.
The provision of permanent power, the resolution of a flow controller discrepancy, procedures, training, and Technical Specifications, however, remain to be completed.
We again apologize for our failure to identify this omission in the earlier implementation schedule in a more timely manner.
We are reviewing how this oversight occurred in order to insure that it is an isolated instance, and to preclude such problems in the future.
We shall be pleased to provide you with the results of our investigation as soon as it is completed in about 30 days.
We would also note that, as discussed in our letter

i Mr. H. R. Denton May 25, 1983 dated March 14, 1980, interim methods were developed and available to permit the estimation of high-level release rates based on direct radiation measurements obtained on the header for the atmospheric steam dump and steam generhtor code safety valves in the event that such data were needed.
Very truly yours, 6
