Nev. Rev. Stat. § 6.110

1. In any county having a population of 100,000 or more, the selection of persons as proposed grand jurors must be made in the manner prescribed in this section upon notice from any district judge as often as the public interest may require and at least once in each 4 years. The clerk of the court under the supervision of the district judge presiding over the impaneling of the grand jury shall select at random the names of at least 500 persons to be called as prospective grand jurors. The clerk shall prepare and mail to each person whose name was selected a questionnaire prepared by the district judge stating the amount of pay, the estimated time required to serve and the duties to be performed. Each recipient of the questionnaire must be requested to complete and return the questionnaire, indicating on the questionnaire his or her willingness and availability to serve on the grand jury. The clerk shall continue the selection of names and mailing of questionnaires until a panel of 100 qualified persons who are willing to serve is established.

2. A list of the names of persons who indicated their willingness to serve as grand jurors must be made by the clerk of the court and a copy furnished to each district judge. The district judges shall meet within 15 days thereafter and shall, in order of seniority, each select one name from the list until at least 50 persons have been selected. A list of the names of the persons selected as proposed grand jurors must be made by the clerk, certified by the chief judge of the district court and filed in the clerk's office. The clerk shall immediately issue a venire, and the court shall summon the proposed grand jurors to attend in court at such time as the district judge directs.

3. The court shall summon the proposed grand jurors, and the district judge presiding over the impaneling of the grand jury shall select at random from their number 17 persons to constitute the grand jury and 14 persons to act as alternate grand jurors. If for any reason an insufficient number of proposed grand jurors fail to appear, additional proposed grand jurors sufficient to complete the panel of grand jurors and alternates must be selected from the list of prospective grand jurors by the district judge presiding over the impaneling, and the persons so selected must be summoned to appear in court at such time as the district judge directs.

4. Every person named in the venire as a grand juror must be served by the court mailing a summons to the person commanding the person to attend as a juror at a time and place designated in the summons. The summons must be registered or certified and deposited in the post office addressed to the person at his or her usual mailing address. The receipt of the person so addressed for the registered or certified summons must be regarded as personal service of the summons upon the person and no mileage may be allowed for service.

5. If for any reason a person selected as a grand juror is unable to serve on the grand jury until the completion of its business, the district judge shall select one of the alternate grand jurors to serve in his or her place.
