Brunner, Chief Reactor Operations and Nuclear Support Branch Region i U.S.
Nuclear Regulatory Commission 631 Park Avenue King of Prussia, PA 19406
Dear Mr. Brunner,
Your letter of March 5, 1981, forwarded combined inspection Report Nos. 50-277/80-35 and 50-278/80-28.
Appendix A addresses two items which do not appear to be in full compliance with Nuclear Regulatory Commission requirements.
These items are categorized as Severity Level IV Violations and are restated below with our responses.
A.
Technical Specification 6.13, "High Radiation Area,: states in part, "Each High Radiation Area in which the intensity of radiation is greater than 100 mrem /hr but less than 1000 mrem /hr shall be barricaded and conspicuously posted as a High Radiation Area and entrance thereto shall be controlled by issuance of a Radiation Work Permit.
Any individual or group of individuals permitted to enter such areas shall be provided with or accompanied by one or more of the following:
1.
A radiation monitoring device which continuously indicates the radiation dose rate in the area...".

Mr. E.
J.
Brunner, Chief Pags 2 Contrary to-the above, on December 27, 1980, two individuals were observed working at the north Scram Discharge Volume header, a high radiation area, without having a radiation monitoring device which indicates dose rate.
RESPONSE
As discussed in the Inspection Report, the two individuals involved were immediately directed to leave the area until a radiation meter could be provided.
They obtained a portable survey meter and continued working within the north Scram Discharge Volume (SDV) header area.
Investigation revealed that the technicians involved had been working in the north and south SDV header areas, both of which were correctly posted as high radiation areas.
As required by the Radiation Work Permit (RWP) common to the two header areas, the technicians used a portable radiation survey meter while working in the south header area.
However, they forgot to take the meter with them from the south header area and entered the north header area without properly verifying that they met all RUP requirements.
The two technicians had worked in the north SDV area for less than ten minutes without a portable survey instrument.
Exposures received by the tuo technicians for the day were well within the daily PBAPS limits of 300 mrem, as determined by Harshaw badge readings.
Following the event, the individuals involved were forcefully reminded by their supervisor to read and obey all RWP requirements each time they enter such an area.
In addition, the first step of the Philadelphia Electric Company disciplinary policy was enforced which includes an oral warning.
Other personnel of the same work group were also reminded of their responsibility to ecmply with RWP requirements.
B.
Technical Specification 3.6.A.1 states, "The average rate of reactor coolant temperature change during normal heatup or cool down shall not exceed 100 degrees F increase (or decrease) in any one hour period."
Contrary to the above, during normal cool down, between 4: 30 PM and 5:30 PM on December 29, 1980, reactor coolant temperature, as indicated by the
'B' recirculation loop temperature recorder, decreased 102 degrees F.

Mr.
E.
J.
Brunner, Chief Page 3
RESPONSE
As stated in the Inspection Report, shutdown cooling was immediately secured when the excessive temperature decrease was discovered.
The operator who allowed the cooldown rate to exceed the cooldown limit was counseled by the Operations Engineer.
This event was previously reported in Licensee Event Report 2 37/IP and, as noted in this Inspection Report, the inspector verified the accuracy of the Licensee Event Report including corrective actions.
Very truly yours, 0 0. _ L d'
