20555 Subj ect: Calvert Cliffs Nuclear Power Plant Units No. 1 and 2, Docket Nos. 50-317 and 50-318 10 CFR 50.72 Dedicatad Telephone Reporting Recuirements

Dear Mr. Eisenhut:

On February 29, 1980, the Commission amended its regulations by adding a new section 50.72 to require that each facility licensed under 10 CFR 50.21 and 10 CFR 50.22 notify the NRC Operations Center as soon as possible and in all cases within one hour of the occurrence of any of twelve types of significant events. Since the dedicated telephone was installed, Calvert Cliffs has made approximately ninety dedicated telephone reports pursuant to this regulation. Shny of these reports were made as a result of overly censervative interpretations of the rather general 50.72 reporting requirementa by operating personnel. To reduce the number of unnecessary reports, site specific guidelines have been developed which serve to clarify the 50.72 eporting requirements as they apply to Calvert Cliffs. These guidelines have 'coen incorporated into Calvert Cliffs Instruction 118, Report-ing Requirements. A copy of the applicable section of this instruction de-scribing the guidelines we will now be following is enclosed for your infor-mation.

We believe, the guidelines are consistent with the purpose of the regulation which requires reporting only significant events. In addition, our objective in attempting to reduce the number of unnecessary dedicated telephone reports is part of our continuing efforts to relieve the Shif t Supervisor and other operations shif t personnel of administrative burdens. However, as in the past, operaticus personnel will continue to be encouraged to make reports if any doubt exists as to the reportability of specific event.

Very truly you-

ENCLOSURE 1

DEDICATED PHONE REPORTS Per the requirements of 10 CFR 50.72 the NRC Operations Center shall be notified of the following events witnin one hour of occurence.

(1) Any event requiring initiation of the licensee's emergency plan or any section of that plan.

- NOTE -

This item should be reported only if an unusual Event or higher EAL is declared. Actions taken in order to assess if an EAL has been reached do not constitute implementation of the emergency plan.

(2) The exceeding of any Tecnnical Specification Safety Limit.

(3) Any event that results in the nuclear power plant not being in a controlled or expected condition while operating or shutdown.

- NOTE -

Since our alant procedures address analyzed plant conditions, they are in that sense " expected".

This item should be reported whenever plant conditions are such that they cannot be controlled by our emergency or abnormal operating procedures (one example of this condition might be a total icss of heat sink).

i

(4) Any act that threatens the safety of the nuclear power plant or site personnel, or the security of special nuclear material, incluoing instances of sabotage or attempted sabotage.

l10TE -

J This item should be reported if an "act" is committed by an individual or group of in-dividuals against the plant or plant personnel.

(5) Any event requiring initiation of shutdown of the nuclear power plant in accordance with Technical Specification Limiting Conditions for Operation.

NOTE -

This item should be reported when the unit is placed in Mode 2.

(6) Personnel error or procedural inadequacy which,-

during normal operations, anticipated operational occurrences, or accident conditions, prevents or could prevent, by itself, the fulfilment of the i

safety function of those structures, systems ard components important to safety that are needed to (i) shutdown the reactor safely and maintain it in i

a safe shutdown condition or (ii) remove residual heat.~ollowing reactor shutdown, or (iii) limit the release of radioactive material to acceptable levels or reduce the potential for such release.

l 7,-

- NOTE -

This iten should be reported if the personnel or procedure inadequacy "by itself" results in a " loss of safety function" such as dis-abling both redundant cenpanents or trains of safety features or disabling both auxiliary feedwater trains.

j (7) Any event resulting in manual or automatic actuation of Engineered Safety Features including the Reactor Protective System.

- NOTE -

Inadvertent actuations of ESFAS or RPS should also be reported under this iten. Planned actuations sach as Surveillance Testing should not be reported.

(3) Any accidental, unplanned, or uncontrolled radio-active release.

(Normal or expected releases from maintenance or other operational activities are not included).

- NOTE -

For gaseous activity, this item should be reported anytime either main vent monitor count rate increases to a count rate equivalent to 25% of the limits specified in Appendix B Technical Specification 2.3.5.1.

if the alarms and increases in count rates cannot be attributed to maintenance or operational activities in progress sucn as Reactor Coolant diversion.

(9) Any fatility or serious injury occurring on the site

and requiring transport to an offsite medical facility for treatment.

NOTE -

This item should be reported anytime an emergency vehicle (ambulance) is required for transport of a victim of fatality or serious injury. Such transport of individuals taken ill on-site need not be reported. Do not report the relatively minor injuries which we transport ourselves (such as eye injurles) as a-precautionary measure.

(10) Any serious personnel radioactive contamination requiring extensive onsite decontamination.or outside assistance.

i NOTE -

This item would include any decontamination effort whicn goes beyond the conventional use of soap and i

water (such as the use of chemical agents) or re-l quiring off-site treatnent.

involving radiactive material which causes or threatens to cause any of the following:

An individual receives 25 RC4 wnole body,150 RD1 to the skin, or 375 REf4 to the extrenities.
